C., August 23d, 1866. an To the Corporators of the Ches. Bay & Potomac River T. W. Canal: GENTLEMEN - I herewith transmit a report upon the feasibility and cost of constructing the 6. Chesapeake Bay and Potomac River Tide-water Canal." ARGUMENT. The length of the proposed canal route from Washington to Annapolis, is 34 miles. The distance between the same points via Potomac River and Chesapeake Bay, is 190 miles; saving in distance 156 miles, and from 24 to 30 hours in time to all the markets of the East. The total saving to the consumers of Cumberland coal alone, would, upon the yield of 1865 and rates of 1866, amount to over one million dollars annually. (For cost of transportation, see appen- dix A). By the proposed canal route, the cost of transportation from Cumberland would be 25 per cent less to New York, 35 per cent less to Philadelphia, and 34 per cent less to Baltimore, than if sent over the Baltimore and Ohio Railroad and inland canal route. Upon the rates of 1866, this would reduce the cost per ton at New York $1.60, at Philadelphia $1.84, and at Baltimore $1.29; resulting in a saving of $576,000 at New York (assuming that one-half brought to tide over the road is shipped to that point), of $165,600 at Philadel- phia (on one-sixth the whole tonnage), and $116,100 at Baltimore. As affecting the cost over the present water lines from Cumber- land to the eastern markets, it would cheapen the cost of transport- ation 10 per cent to New York, 11 per cent to Philadelphia, and 12 per cent to Baltimore, and reduce the cost of coal to New York 54 cents per ton, 50 cents to Philadelphia, and 43 cents to Baltimore. Assuming, as in the first case, that two-thirds is sent to New York, one-sixth to Philadelphia, and one-sixth to Baltimore, the result would be a saving of $123,600 at New York, $28,500 at' Philadelphia, and $24,500 at Baltimore; making a total saving to Digitized by Google IV. the coal consumers of New York of $700,000, Philadelphia $194,- 100, and Baltimore of $140,610; total $1,034,710, equal to an average reduction of $1.20 per ton. As to the local trade with the District of Columbia, the advan- tages gained are equally as important. From Washington, the cost of transportation would be 13 per cent less to New York, 26 per cent less to Philadelphia, 38 per cent less to Havre de Grace, and 40 per cent less to Baltimore than if sent via the Potomac River, Chesapeake Bay and inland canal route. Assuming the consumption of anthracite coal within the district at 150,000 tons annually (which is not an over estimate), and that one-half comes from Philadelphia and the balance from Havre de Grace the saving to consumers upon the rates of 1866, from Philadelphia would be $31,125, and from Havre de Grace, $28,500 total $59,625, equal to an average reduction of 40 cents per ton. The average distance saved to the above points is 153 miles, and in time from 24 to 30 hours. By referring to appendices B and D, it will be seen that the con- struction of this canal is of vital importance to the Chesapeake and Ohio Canal. Great difficulty is now experienced in obtaining vessels at Georgetown, and the consequence is, that large shipments now made at this port, are by vessels especially chartered at New York and Boston at increased rates. This embarrassment is not experienced at Baltimore, from the variety and magnitude of its commerce, and would not be so for the Chesapeake and Ohio Canal if its terminus was brought near Baltimore. Annapolis (the terminus of the proposed canal) is only 38 miles from Baltimore, while Georgetown is 225 miles; and the distance by ocean, from Anna- polis, is 70 miles less to New York than from Georgetown. This advantage, together with the control of railroad lines leading from- Cumberland into the mines, would make the coal tonnage of the Chesapeake and Ohio Canal equal to one million tons annually, instead of one-third of that amount. The Chesapeake and Ohio Canal Company now pay the Cum- berland and Pennsylvania Railroad Company $1.04 for the trans- portation of a ton of coal 23 miles, from the mines to the canal, 150 per cent greater than charged upon any of the coal roads of Penn- sylvania, as shown in appendix D. The actual cost of transporting the same over the Baltimore and Ohio Railroad would be 22 cents Digitized by Google V. per ton, a difference of 82 cents per ton that would be saved if con- trolled by the canal company. The rates now charged via ocean, from Baltimore to New York, are $2.65 per-ton, and from George- town, $3.00. Allowing the same rates from Annapolis, and the charges would be $2.48 per ton, a saving of 52 cents per ton, if shipped at Annapolis instead of Georgetown; and a total direct saving by these improvements suggested at the termini of $1.34 per ton. The coal tonnage of the Chesapeake and Ohio Canal, for 1865, was 343,202 tons. Assuming that two-thirds of this quantity went to New York, the amount that would have been saved on this, is $281,425 at Cumberland terminus, and $119,000 at Anna- polis terminus; total $400,425, equal to 10 per cent on a capital of four million dollars. By referring to appendix D, it will be observed that the lowest the Baltimore and Ohio Railroad can reduce its rates, is mills per ton per mile, while upon the same relative basis of cost the Chesapeake and Ohio Canal can reduce its rates as low as 4100 mills per ton. These rates are without profits to carriers or stockholders. As shown in appendix A, the average cost of transportation of coal upon railroads is 2½ times the average cost on canals, 4 times the average upon tidal rivers and bays, and 8 times the average of coal sea-borne. The average cost of management on gross receipts, for railroads, average 55 to 65 per cent, and for canals 20 to 35 per cent. In the analysis of canals and railroads, appendi D, it was found by experiments on the cost of fuel over different roads, that Cumberland coal was 121 per cent cheaper for locomotive uses than the semi-bituminous coal of Northern Pennsylvania, 141 per cent cheaper than anthracite, and 54 per cent cheaper than wood. Size, Capacity and Cost of Canal. The size of the proposed Chesapeake Bay and Potomac River Tide-water Canal and locks are of the same dimensions as the Delaware and Raritan, thus admitting the largest class of boats trading with New York and Philadelphia to the wharves of Wash- ington without transhipment, and of a capacity to pass vessels of 270 tons burthen. The summit level is 90 feet above mean tide, requiring 18 lift locks of 10 feet each, and two tidal locks, seven Digitized by Google VI. feet lift each. The prism is 75 feet wide at surface of water, 47 feet at bottom, and seven feet depth. The locks are 110 feet in length between quoins, and 24 feet wide. The total quantity of water required to supply this canal is 12,487 cubic feet per minute, for 270 days navigable season, based upon a trade of 120 passages per day, and annual tonnage capacity of six to eight million tons. It is proposed to obtain this quantity of water mainly from the Big and Little Patuxents, which furnished in the aggregate, from careful measurements last August, 8600 cubic feet per minute; the balance from one or more reservoirs on the Big Patuxent The drainage area required to supply this quantity for 270 days; is 27,071 acres, including area of pond. Ample facili- ties are offered for the construction of reservoirs and receiving from this source an abundant supply of water, or four times the quantity required. upon the branches of the Big Patuxent alone, as will be seen by reference to page 33. The estimated cost of canal on the South River line, for timber locks and bridge supports, and inner slopes faced with slope walls and lining the entire length of canal, including five per cent for contingencies, is $3,539,420. The same, without slope walls and contingencies, $3,045,106. The estimated cost for wooden locks and bridge supports, with protection walls on both slopes for one- half the length of canal, including five per cent for contingencies, is $3,369,390, equal to $132,133 per mile. The same, upon the line terminating at Round Bay, is $3,552,101, equal to $139,298 per mile. Since the completion of the surveys proper, and while the report and estimates were being prepared, a reconnoissance was made, by which it was found that the lines could be shortened three miles without materially increasing the cuttings. This would reduce the cost of the South River line $396,396, making the total cost upon last-mentioned basis $2,972,994, and the Round Bay line $3,134,207. If the South River line should terminate at South River, instead of continuing the canal through the ridge 1½ miles to Annapolis, the total cost would be $2,769,294. The following presents the esti- mated cost of the two lines as revised, with wooden locks and bridge supports, and slope walls and lining for one-half the length of canal, including five per cent for contingencies: Digitized by Google VII. South River Line, terminating at South River. $2,769,294-$115,383 per mile. " " " " " Annapolis 2,972,994 = 116,588 " Round Bay Line " " Severn River, 3,134,207 - 122,910 " The inducements presented for adopting the Round Bay line are, that if desirable at any future time to extend this canal to Balti- more, it could be accomplished at a small expense by connecting the arms of the bay, requiring in the aggregate only from 21/2 to three miles of canal, which would shorten the distance between these points nearly one-half, or 15 miles, and make the total distance from Washington to Baltimore 51 miles, 174 miles less than by the Chesapeake Bay and Potomac River, and only 11 miles greater than by railroad. I am of the opinion that a canal thus constructed from Washington to Baltimore, the cost would not exceed $3,850,000. As shown in the analysis of canals and railroads, appendix D, all of the Atlantic coast canals, between New York city and Pamlico Sound, are of the first-class investments of this country. The Chesapeake and Albemarle Canal yields an annual net revenue of 21 per cent on its cost; the Chesapeake and Delaware, 10 per cent, and the Delaware and Raritan, 24 per cent on its cost. The Chesa- peake and Ohio Canal, under its present bad management, yields an annual net revenue of 7% per cent on a capital of $2,640,340 the Baltimore and Ohio Railroad, 17 per cent net revenue on its cost. The Atlantic coast canals form an inland communication for vessels of 270 to 300 tons burthen from New York city to Pamlico River, a distance of 514 miles. For a more full discussion of the questions involved in this pro- ject, I would most respectfully call your attention to the following report and appendices: Appendix A shows the cost of transportation of coal, and freight other than coal, upon railroads, canals, tidal rivers and bays, and sea-borne. Appendix B embraces descriptions of the principal bituminous coal mines, quality and character of coal, also the relative cost and distances of same from market. Appendix C-Sketch of Maryland, its climate, soil, productions and resources, physical characteristics and the estimated revenue that would be received along the line of the proposed canal. Appendix D embraces descriptions in detail, also an analysis of Digitized by Google VIII. each of the Atlantic coast canals, showing trade, cost of manage- ment and net revenue on investment; also same for the Chesapeake and Ohio and New York State canals for 1865, and the Baltimore and Ohio Railroad for 1863. The latter embraces important exper- iments and deductions on the cost of fuel, also the service of loco- motives. Appendix E-Synopsis of all former surveys for a canal from Washington to Baltimore. Appendix F-Report of Thomas Franklin, assistant engineer, giving elevations above mean tide and distances upon the lines sur- veyed for the present proposed canal. In regard to the probable business of the proposed Chesapeake Bay and Potomac River T. W. Canal, I would add: That from the careful analysis made of the length of routes and the cost of trans- portation over each, the great advantages resulting from its construc- tion would make it the key controlling the entire trade from the Cumberland coal fields and the District of Columbia. It would draw commerce to the District, and take all of that which now passes down the Potomac, destined eastward. It would restore and establish the commercial supremacy of Washington, SO long abandoned to her more enterprising sister cities, and convert her capacious canal, now used as a sewer, into a harbor for all transhipments from the interior, of traffic destined to markets along the coast east of Baltimore. These results will most assuredly be secured, as already demon- strated; and if the commerce of the District, with an aggregate popu- lation of 100,000 inhabitants, together with the advantages to secure at least seven-eighths of the traffic from the Cumberland coal fields, is an inducement to capitalists, then I would recommend the speedy construction of this canal. I have adopted the method of showing the ability of this canal to compete, rather than attempt an estimate of its probable tonnage and revenues. Respectfully submitted. S. H. SWEET, Engineer in charge. Digitized by Google REPORT. The surveys were commenced March 14th, and the field work completed about the middle of June, 1866. During this time over 100 miles were carefully examined with the transit and level, and 50 miles of reconnoissance made with the level only. The examinations were first directed toward finding a feasible route for a tide-water canal, and, failing in this, our instructions were to obtain the most practicable route for an elevated or lock canal. EXAMINATIONS FOR A TIDE-WATER CANAL The surveys were commenced on the Eastern Branch Potomac, at the mouth of " Beaver Dam Creek," and the valley of this stream was surveyed four miles from its mouth, resulting in an elevation of 80 feet above mean tide. This line was abandoned, and another run up the "Cat-tail Branch a distance of six miles, and meeting with an elevation of 181 above tide; a third line was traced up the northeast prong of the Cat-tail Branch, meeting with an eleva- tion of 1561 feet above tide 61 miles from the Eastern Branch. This line was also deemed impracticable, and another line was surveyed up the "Cabin Branch" a distance of four miles, at which an elevation was found of 110 feet above tide within two miles of the summit. A reconnoissance was then made in the vicinity of the head-waters of the Piscataway, to find, if possible, a gap through the ridge or table land; but the country proved more formidable than by the first lines, and all further attempts for this object were abandoned. This singular plain, commencing at the foot of Parr's Ridge, is of comparatively recent formation, and belongs to the great Atlantic plain, which extends from the Hudson to the Mississippi. Parr's Ridge (the base of which is composed of primary rocks of the stratified series) was once the original shore line of the sea, and the Digitized by Google 2 intervening country to Point Lookout (composed of tertiary beds of clay and sand, highly fossiliferous) was by a slow process uni. formly packed by the united action of the two great rivers along its borders, the Potomac and Susquehanna. The records of numer- ous surveys show that the highest elevations throughout this lower plain, as also the lowest depressions, keep about the same general level above the sea. Parr's Ridge sweeps semi-circular from the Susquehanna, passing about 30 miles north of Baltimore, reaching the Potomac below the mouth of the "Monocacy," with a uniform elevation of from 850 to 1,000 feet above tide. EXAMINATIONS FOR A LOCK CANAL After a thorough examination of the country, the most practicable route for a lock canal was found, having two feasible termini (from the Big Patuxent) on Chesapeake Bay one on South River, and the other on the Severn, at Round Bay. This line, for description, is called upper line B. This line commences at the Annacosta or Eastern Branch Poto- mac, three-quarters of a mile from Bladensburg, and about 41 miles from Washington. It follows up the Paint Branch" about seven miles, with a uniform grade of 10 feet to the mile; thence up the Beaver Dam Branch about four miles, with a grade of 13½ feet, crossing the summit, 156 feet above tide, upon the land of Luther D. Jones, Esq. It then follows down Cass Valley" about two miles, on a grade of 32 feet per mile, reaching an elevation of 90 feet above tide on the land of Dr. Wm. Duvall. The line then follows along the western bank of the Big Patuxent valley, at an elevation of about 95 feet above tide, for 2½ miles, crossing the Horse pen Branch," the valley of which is 50 feet above tide. The line crosses the Big Patuxent at "Priest's Bridge," one-half mile below the junction of the Little with the Big Patuxent. The surface of water of the latter stream was found 25 feet above tide. From the Patuxent the line passes up "Sanford's Branch' about two miles, with a grade of 22 feet per mile, and crosses the summit, between the Patuxent and South River, 165 feet above tide. From this summit the line follows down "North Run Branch" three miles, to South River, at Clagett's Landing; thence down South Digitized by Google 3 River 4⁴ miles; thence across the ridge 1½ miles, to Annapolis Bay. The summit of this ridge is 50 feet above tide. The total distance, by this line, from Washington to Annapolis, is 34½¹ miles, 251 of which is canal. ROUND BAY TERMINUS, This line commences three-quarters of a mile west of the Big Patuxent, on the line described above, and this stream is crossed above the forks. The surface of water in the creek is 48 feet above tide, and the summit, between the Little and Big Patuxents, 165 feet above tide, on the land of Chas. T. Bealmer, Esq. From the summit, the line approaches the Little Patuxent on a grade of 60 feet per mile, and crosses this stream near " White's Mill," the surface of water being 43 feet above tide. The line then follows up " Tower's Branch," reaching the summit, between the water sheds of South and Severn rivers, on the land of L. W. Wharfield, 1321 feet above tide. "From this summit two lines are presented, one to the Severn and the other to South River; the latter, from recon- noissance, found one mile shorter, and the grade as favorable." (See Thomas Franklin's report, Appendix E, giving report of the seve- ral lines in detail, also elevations and distances upon all the lines.) The summit between the South and Severn rivers is found, on this line, at an elevation of 100 feet above tide; thence (cross- ing the Elk Ridge Railroad 100 feet above tide) passes down 'Indian Creek," on a grade of about 231/2 feet per mile, to Round Bay, on the Severn, seven miles from Annapolis. The length of this line is as follows: Distance from tide to tide-Potomac to Severn River-total of canal. 251 miles. do do Eastern Branch Potomac to Washington 41 de do used of Severn River, from terminus to Annapolis 7 do Total distance from Washington to Annapolis 362 miles. Since the commencement of this report, Messrs. Franklin and Carter made a reconnoissance with the level, with a view of improving the above described lines, in which they were very successful, as will be seen from the following report of Mr. Franklin: "The line is much shorter than either of the other lines, it being the chord of which the Beltsville, or upper line B, is the arc. By this line the total dis- tance of actual canal would be reduced to 221, miles to either South River or Round Bay, and the summit but a few feet higher. The ridge between the 'Fally and Horse-pen Branches' can be avoided in part by increasing the length of line about one-half mile." Desiring to be on the safe side, I have made no estimate upon this improved line, and have not in any of the calculations made use of it in the Report proper. Digitized by Google 4 GENERAL PLAN AND SIZE OF CANAL ADOPTED. In deciding upon the height of the summit level, especial import- ance was given to the reduction of lockage. From an accurate calculation, the grades or lockage on the Pennsylvania canals increase the actual cost of transportation (exclusive of tolls) 40 per cent. Upon the New York State canals, the average time, for the sea- son, consumed in overcoming feet of lockage, is equal to that in passing over one mile of canal. The time in passing through the locks average 25 feet, as equal to one mile, but in falling from and recovering the original speed, together with other detentions, bring it down to the above standard. By fixing the height of the summit level at 90 feet above mean tide, not only was the lockage reduced to a minimum, but also the cutting across two-thirds of the summit level, and giving an eleva- tion deemed most practical for crossing the valley of the Big Patuxent, and for diverting its waters with that of the Little Patuxent, by artificial feeders about five miles in length, into the summit level of the canal. The size of the prism and locks were fixed the same as the Delaware and Raritan Canal" for two reasons: first, that the largest class of boats trading between the cities of Philadelphia and New York, could land their cargoes at the wharves of Washington without transhipment; and, secondly, that locks and canals with these dimensions, secure greater economy in the cost of transporta- tion commensurate with the cost of the work, than any within the States of Pennsylvania and New York, except the Erie, Cayuga and Seneca, as will appear from the following calculation of the cost of movement, is based upon prices previous to 1862, and reduced to level canals.

The size of prisms are about the same, but the locks of the former are nine feet less in width and ten feet less in length than the latter; and, while the cost of construction is about the same, the Delaware and Raritan has double the capacity. DESCRIPTION AND ESTIMATED COST OF EACH LINE, AS LOCATED. UPPER LINE B. The total length of this line, from Washington to Annapolis, is 341 miles; 251 of which is actual canal, as follows: Distance from Washington to Annacosta, 41 miles; Annacosta to summit, between Potomac and Patuxent, 11± miles; summit to Big Patuxent, miles; Big Patuxent to summit, between Patuxent and South River, 2ₜ¹σ miles; summit to South River, 31½ miles; South River to Crab Creek, 4 ⁴ miles; Crab to Spa Creek or Annapolis, 1½ miles. There are 20 locks, 18 of which are lift locks of 10 feet each, and two tide locks at each end, of seven feet lift each. Lock No. 1 is loca- ted about 800 feet from the Annacosta, and the summit lock, No. 10, is 91 miles from the Annacosta; the intermediate ones, at nearly equal distances apart. The length of the summit level, or from No. 10 to 11, is miles, and from summit lock to South River, 21 miles; the intermediate locks being at nearly equal distances apart. These locks overcome a rise and fall of 180 feet. The grade from the Annacosta to the summit cutting is uniform, and averages 14 feet per mile. The depth of cutting to the summit lock averages from three to four feet at the head of each lock ascending, and 12 feet at the foot. The total quantity of excavation on this portion is about 985,900 cubic yards of earth, and about 66,400 cubic yards of embankment. The distance from the summit lock to the summit cutting is 1% miles, the depth of cutting regularly increasing from 3½ feet to 66 feet at the summit, and falling again to a cutting, on the opposite side, of seven feet, in a distance of 31 miles from the summit lock. The total quantity of excavation in this distance, through the sum- Digitized by Google 7 mit, is 2,420,100 cubic yards, 1,193,400 cubic yards of which is from a cutting of over 20 feet. The depth of cutting from the foot of the summit to the Patuxent is from four to five feet, except for a distance of 500 feet each side of the "Horse-pen Branch," where it is from 20 to 25 feet. The canal level crosses the Horse-pen Branch at an elevation of 40 feet above the water in the creek, and the width of the valley on this line is about 1,000 feet. The surface of water in the Patuxent is 65 feet below the canal level, and the bottom of the valley about 60 feet below. The width of the valley, at the bottom, is 1,800 feet, and at the top or canal level, 2,800. To pass this stream will require a four arch stone culvert, or one with a single arch of 75 feet span, and to cross the valley, 1,345,800 cubic yards of embankment. For 11 miles east of the Patuxent the line passes along the slope of Sanford's Branch, where the excavation is just enough to make the embankments. The greatest depth of cutting through the sum- mit, between the Patuxent and South River, is 75 feet, and the distance through it, on a line of seven feet cutting, is 1½ miles, requiring for the distance 1½ million cubic yards of excavation, one million of which is from a depth of over 20 feet cutting. From the summit lock, No. 11, to South River, the surface of the ground falls with a uniform grade of 40 feet per mile, and the cutting averages 12 feet in depth at the foot of each lock descending, and from 21/2 to three feet at the head. It is proposed to use South River from Clagett's Landing to Crab Creek, a distance, by triangulation, of 4₅ miles. The depth of water, from the termination of the canal line to six feet depth, is about one-half mile. The distance across the ridge of land separating South River from Annapolis Bay, is 1½ miles. The greatest depth of cutting is 561 feet, requiring the removal of 926,000 cubic yards of earth excava- tion. No rock is met with on the whole line, and the material being of loam, clay and sand, mixed in proper proportions, can be easily handled.

ROUND BAY LINE C. From Eastern Branch Potomac or Annacosta to within three fourths of a mile of the west side of the valley of the "Big Patux- ent" the line is the same as described on upper line B. Commencing on the summit level, three-fourths of a mile west of the Patuxent, the canal line is carried across the valley of the "Big Patuxent" at an elevation of 48 feet above the water, and about 22 feet above the valley. The width of the valley, at this elevation (on the canal level), is 3,800 feet, and at the bottom, 2,500 feet. To pass this stream will require a four arch stone culvert, or, which would be more preferable, a single semi-circular arch of 50 feet span and to cross the valley, 538,000 cubic yards of embank- ment. The greatest depth of cutting through the ridge between the Little and Big Patuxent is 65 feet, being one mile from the Big, and 1100 miles from the Little Patuxent; making the distance between these two streams 2TTor miles. The distance through this summit, on a line of seven feet cutting, is 4,000 feet, and the quantity of excavation required, about 1,266,000 cubic yards, 800,000 cubic yards of which is from a cutting of over 40 feet, 2 Digitized by Google 10 The canal level crosses the valley of the Little Patuxent at an elevation of 43 feet above the water, and about 40 feet above the valley. The width of the valley, at the bottom, is about 1,200 feet, and at canal level, 3,200 feet. To pass this stream will require a four arch stone culvert or a single arch of 50 feet span and to cross the valley, 831,000 cubic yards of embankment. After leaving the Little Patuxent, the line passes through a wide ridge dividing the waters of South from Severn River. The length through this ridge, on a line of seven feet cutting, is 8,600 feet, and the distance through, on a line of 30 feet cutting, is 7,200 feet. The greatest depth of cutting is 42 feet, and the average for the whole distance about 34 feet. To pass through this ridge will require the removal of 1,371,000 cubic yards of excavation. This summit commences about 20 miles and ends 22 miles from the Annacosta. The eastern end of the summit level is 2TTTO miles from Round Bay, and 2,100 feet west of the "Annapolis Elk Ridge Railroad." It is proposed to pass the canal under this railroad, by a tunnel, as the road is about 30 feet above the bottom of canal. The cut- ting from the summit lock to Round Bay, is light. The grade is uniform, and the locks are located at nearly equal distances apart. The distance from the canal terminus, at Round Bay, to Annapolis, by the Severn River, is seven miles. The total distance, by this line, from Washington to Annapolis, is 364 miles, 251 of which is actual canal.

It would reduce the original cost of canal over one-half million dol- lars, greatly facilitate the completion of the canal, which could be made available in transporting and distributing the heavier mate- rials for stone structures whenever the old ones require rebuilding. Wooden locks will last, with slight repairs, 20 years. COST OF CANAL PER MILE.

The observations were generally made daily, though intervals of one or more days occurred in which they were discontinued, owing to rain or other causes. The height of water was registered anew after such intervals, so that no variation of surface, by rain or otherwise, was allowed to affect the result.

The average loss for the first 421/2 days was, from the puddled basin 0.27, or over one-quarter inch per day, and from the basin not puddled 0.332, or one-third inch per day, leaving an average loss from filtration of 0.062 inch, or one-twelfth of an inch. The mean daily evaporation for the month of August was about one-third of an inch per day, and was assumed at this rate for seven consecutive months in the calculations made of the quantity of water received into the basin from drainage sources in the Central Park. The filtration was assumed at one-tenth of an inch daily. Digitized by Google 19 Collecting the foregoing results, and assuming the greatest daily evaporation from each, we have the following as the maximum evaporation from water surface for the entire navigable season of 270 days: From Table No. 1 0.2163 of an inch daily.

The surface of water in the proposed canal is 75 feet wide and 251 miles long; hence, the total loss, from evaporation, will be 7.61 cubic feet per minute per mile, or 75 X 5280 X 1 inch X 251 = 194.05 for 24 X 60 the whole length. FILTRATION. Numerous experiments were made upon the Erie and Chenango canals to obtain the total loss from leakage at structures, evaporation and filtration. The size of canals were 28 feet on bottom, slopes 1½ to one, and four feet depth of water. The total loss upon 36 miles of the Erie Canal, as determined by O. W. Childs, from these causes, was 85 cubic feet per minute per mile; and upon the Che- nango Canal, from evaporation and filtration, by Messrs. Tracy and Talcott, cubic feet per minute per mile. The average loss from all the structures, except locks, upon both canals, was nine cubic feet per minute per mile, and from evaporation, three cubic feet per minute per mile. The original loss assumed for new canals of these dimensions for evaporation, waste and filtration was 100 cubic feet per minute per mile; calling the loss from evaporation and waste 12 cubic feet per minute per mile, there would be left for filtration, in the first result, 73 cubic feet, upon the second, 621, and upon the third, for new canal, 88 cubic feet per minute per mile; making the average 741 cubic feet, which quantity is assumed for the Potomac and Chesapeake Tide-water Canal in the calculations for filtration. Filtration upon canals, of different depths and areas, are as the square root of their depths and areas pressed; and, areas being the same, are as the square root of their depths. Hence, the width of Digitized by Google 20 bottom that would discharge a quantity equal to that discharged from the slopes, would be, for a canal 28 feet wide on bottom, four feet deep, with slopes 11 to one, as follows: √4=2 and √2=1.41 for slopes; the length of both slopes=12 feet, which is inversely as the square root of depth on bottom to the square root of depth on slopes, viz., 2:12::1.41:8.46 the width of bottom, and the whole width=8.46|28=36.46 feet. Applying the same principle to the Chesapeake Bay and Potomac River Tide-water Canal (being 47 feet wide on bottom, seven feet deep, and slopes two to one), 7=2.645 for bottom, and √3.50= 1.87 for slopes, the length of both slopes=28 feet; hence, 2.645:- 28::1.87:20, the width of bottom and whole width=67 feet. If the former had seven feet depth instead of four, it would discharge V4:~7::73]:97.20 cubic feet; hence, the quantity discharged by the proposed canal (36.46:67::97.20)=178.61 cubic feet per minute per mile; allowing, relatively, the same filtration through the bottom as the sides. The general formula used, and much more simple, gives about eight per cent less in result, viz., (4/4+28/4):7v/7+47 V7::1:2.24x73=164.64 cubic feet per minute per mile. WASTE AT STRUCTURES. From careful measurements at structures, waste weirs and acque- ducts, upon the Chenango and Erie canals, the average loss from this source was about nine cubic feet per minute per mile ; hence, increasing this in proportion to the increased size of canal, and it equals (40+28); cubic feet per min- ute per mile. Collecting results, the total loss upon one mile of canal, exclusive of water required for locks=200.35 cubic feet per minute per mile. LOCKAGE WATER AND LEAKAGE THROUGH GATES, AT SUMMIT Locks. This item is naturally resolved into the amount of trade of the canal, and the number of locks full of water required for each boat. Under the most favorable circumstances, one lock full is required for each boat, and two locks full is the greatest ever re- quired for one boat. Considering the great irregularities of trade, found in practice to effect this item unfavorably, I am of the opinion Digitized by Google 21 that nothing less than three locks full should be allowed for the passage of every two boats. The following are the greatest number of lockages made in any one day upon the New York State canals: Erie Canal 264 (double locks) and 199 single Champlain Canal, 88; Oswego, 96.; Cayuga and Seneca, 86; Chemung, 51; Genesee Valley, 58; and Crooked Lake Canal, 32 lockages. The greatest number of lockages made in any one season on the Chesapeake and Delaware Canal was 15,417 or 57 lockages per day. The length of navigable season averages upon the New York State canals 240 days, and reaches as high in some seasons as 255 days. When locks are in good condition, boats can be passed in five minutes; but when locked in rapid succession, it takes from seven to eight minutes, caused by a too sudden reduction of water directly at the head of the lock. It is believed safe to assume, for the trade of this canal, 120 lock- ages a day, or one every 12 minutes, requiring 180 locks full of water, and the length of navigable season at 270 days. This will give a capacity (calling the trade going westward one-half of east- ern) of 6,561,000 tons, 10 per cent greater than ever experienced on the New York State canals. The two summit locks are 110 feet between quoins, 241 feet average width, and 10 feet lift. Hence, the quantity of lockage water would equal (110 x 24} x 180 x 10) 3,368.70 cubic feet per minute. To this should be added 12 per cent for flushing and waste, making the total lockage water=3773 cubic feet. For the item of leakage much depends upon the condition of the locks. They are found to vary upon the Erie Canal, with the same lift, from 800 to 1300 cubic feet per minute. Lock No. 60, Erie Canal (18 feet wide and 10 feet lift), was found to leak 1344 cubic feet per minute, and No. 61, of eight feet lift, 1220 cubic feet. The locks upon the Chenango and Erie canals (15 feet wide and 8 feet lift) were found to average 500 cubic feet per minute. Assuming the leakage at 1200 cubic feet per minute for a lock 18 feet wide and 8 feet lift, that for 10 feet lift would be equal to (8:/10::1200=) 1344 cubic feet per minute. Hence, the leak- age of the two summit locks of the Chesapeake Bay and Potomac River Tide-water Canal would equal (18:24::1344:1803> 3606 cubic feet per minute.

FROM STREAMS. Careful measurements were made August 18, 1866, of the natural flow of the following streams. At the time of measurements, no rains, of any more than ordinary character, had fallen, and the streams were pronounced, by the inhabitants, lower than they had been for many years. The sources of these streams are from 'Parr's Ridge," and are of the most permanent and constant char- acter. BIG PATUXENT RIVER. This river is the largest within the State. It rises in Parr's Ridge, and flows southeasterly through the lower plain. It is navigable to Nothingham, 40 miles, for vessels of 250 tons, and for large boats, 15 miles, to Queen Anne. About 60 miles from its mouth, it approaches within five miles of one of the arms of Chesapeake Bay, and flows southward, nearly parallel, within 10 miles from the western coast. After flowing eight miles from its source, it receives the Cabin Branch, 7½ miles long, from the north four miles further, it receives the Cat-tail Branch, nine miles long, also from the north; six miles lower, Hawlings river, 12 miles long, enters, and soon after joined by the Little Patuxent, from the east. These are the main branches of the "Big Patuxent," and are remarkable for their permanency or constant flow. The direct drain- age of the Patuxent was estimated by Geo. W. Hughes, in 1837, at 100 square miles, and the Cat-tail Branch at 46 square miles. The point chosen for gauging this stream was directly at the Baltimore and Ohio Railroad bridge. The section of the stream at Digitized by Google 23 this point was uniform and the slopes regular. The length of section from which the measurements were made was 50 feet in length, and the velocity taken nine times at different points on the surface, and the depths or soundings taken throughout the entire section. The measurements were made between the hours of 9 and 11 o'clock A. M., and found to furnish 3616 cubic feet per minute. This stream was measured at the mill immediately above, in May last, and found to furnish, at this time, 4016 cubic feet per minute. It is proposed to introduce this water into the canal by a feeder about five miles long, entering the summit level on the lands of Dr. Duvall. LITTLE PATUXENT RIVER. This stream rises also in Parr's Ridge, gathering the waters from a broader extent of country, and rather intercepting the upland drainage from Parr's Ridge from flowing into the Big Patuxent. There are three considerable branches to the main stream before it reaches the Baltimore and Ohio Railroad. It joins the Big Patux- ent about seven miles below the railroad. The section selected for obtaining the measurement of the flow in this stream, was about 1000 feet below the Baltimore and Ohio Railroad. The section was uniform, of regular width and uniform velocity. Six observations of the surface velocity were made, and the depths obtained throughout the section. It was found to fur- nish 4771 cubic feet per minute. Measurements were also made of Dawson's and Rogues' Branches, that enter the Little Patuxent from one-half to four miles below the railroad. These two were found to furnish, in the aggregate, 222 cubic feet per minute. All of these streams are remarkable for their constant and permanent flow. Collecting the foregoing results, we have from natural sources : From the Big Patuxent River 3616 cubic fect.

The quantity of water that can be collected into a reservoir, depends upon the character of soil, slopes of the catchment Digitized by Google 24 basin, and the annual rain-fall. From the experiments made by Mr. John B. Jarvis, in this State, 45 per cent of the annual fall of rain was collected. From experiments in Ireland, on the River Robe, in 1851 and 1852, an average of 571 per cent passed into the river, and upon the catchment of Ballinrobe River, 58 per cent. In the Journal of the Royal Agricultural Society of England, Mr. Josiah Parks states, that 421 per cent of the annual rain-fall filters through the soil, and 571 per cent is evaporated; being mean results of eight years' observations. Upon the whole area of England, Neville estimates that one-third of the annual rain-fall passes into the streams and sea. Upon flat tillage soils of Ireland, it was found that only 40 per cent of the annual rain-fall filtered through the soil, while the drainage in the high, steep districts ranged from 75 to 100 per cent of the rain-fall.

A rain gauge was established at Eaton Brook, and the quantity of falling water carefully recorded ; at Madison Brook, the rain gauge kept at the Hamilton Academy has been furnished for this purpose.

"From table No. 2, it appears the average drainage, from June to December, inclusive (seven months), was 0.392 of the falling water, or nearly two-fifths; and the average, from June to October, inclu- sive (five months), was 0.319, or nearly one-third of the fall. August is the minimum month, and shows a drainage of 0.192, or nearly one-fifth of the fall. July is the maximum month (except December), and the drainage was 0.414, or over two-fifths of the falling water. "From table No. 3, the drainage for the year was, including snow on the ground, 0.449, or nearly one-half falling water; January to May, inclusive (five months), 0.662, or two-thirds of the fall; June to October, inclusive, was very uniform, although the falling water is very different, which causes a great range in the ratios for several months. This was produced by the reservoir on Madison Brook, which retained the flood waters and discharged them nearly uniform through the reservoir pipes, causing the highest ratio to appear in the month of the least fall, and the smallest Digitized by Google 27 ratio in the month of the greatest fall, of water. It is, therefore, obvious that an average of June to October (five months) will be required to give a proper view of the drainage during the season of greatest evaporation. "From June to October, the Eaton Brook valley gave a drain- age of 0.319, and Madison Brook valley, 0.246 of the falling water. This result, it is believed, has been produced by the different characters of the two districts drained. The Eaton Brook valley is, in itself, very narrow, and the grounds that drain into it are generally quite steep, and the soil mostly of a very close texture. The Madison Brook valley is much wider, the slopes of the ad- joining lands that drain into it more easy, and the soil in some parts more porous than that on Eaton Brook. "The Eaton Brook valley, I should think, would afford more than an average drainage over a large district of country, including the usual varieties of soil; and the Madison Brook valley would not differ materially from the general average." Five years after the above experiments by Mr. Jarvis, Mr. Wm. H. Talcott found, from actual measurement, that to discharge through the pipes of Madison Brook reservoir the drainage shown in the table from June to October, inclusive, an average of twenty millions cubic feet each month, required a head of 30 feet, and remarks that, " with a depth of 45 feet of water, the surface area amounts to 235 acres." It may, then, reasonably be supposed that 30 feet deep will cover at least 100 acres, and, therefore, the drain- age of this valley must have been exposed, during the whole time, to the waste of the reservoir of these dimensions. The Canal Commissioners, in their report of 1835, say, in rela- tion to waste from reservoirs, that " a special examination of the banks of reservoirs Nos. 2 and 3, on Madison Brook, has shown that the soil is much more porous than was anticipated, and more particularly No. 2." "This," remarks Mr. Talcott, "indicates that the waste from filtration may have been very considerable in addi- tion to the evaporation." Mr. Talcott found from measurements in 1840, that the fall of rain on Oil Creek valley, during September, October and November, was 5.54 inches, and the drainage 1.17 in- ches (ratio 0.211), leaving 4.37 inches for the consumption of the ground by evaporation, or a ratio of 0.789 of the fall. Digitized by Google 28 From table No. 2, the fall of rain for September, October and November, in 1835, was 6.54 inches, and the drainage 2.19 (ratio 0.334), leaving 4.35 inches (a ratio of 0.666) for evaporation from the ground. The total fall of rain on Madison Brook valley, from January to December, was 35.26 inches, and the drainage 15.83 inches (ratio 0.449), leaving 19.43 inches (ratio 0.551) for evapora- tion from the surface of the ground. Doyle and Dalton determined the evaporation from the surface of the ground, in 1796, 1797 and 1798, to average 25.14 inches, which was 76 per cent of the rain-fail, and 24 per cent for filtration and drainage; and from the surface of water the evaporation was found to average 44.43 inches, or nearly 24 per cent greater than the rain-fall. ENGLISH AUTHORITY AND EXPERIMENTS ON DRAINAGE. The following tables, Nos. 4 and 5, show the monthly fall of rain, and the corresponding discharge of the river Robe, at Baltimore, County of Mayo, Ireland. The area of drainage or catchment basin being 70,000 acres, the lower end 100 feet and the upper end 336 feet; the average height of the surface, about 180 feet above the level of the sea. The average fall of the river, not including the rapids, is from one to two feet per mile; the catchment is about 20 miles ong, about one-tenth of the area bog or low marsh, and nine-tenths clayey and gravelly; the river is about 33 miles long.

RAIN-FALL IN MARYLAND. The quantity of rain which falls annually varies with the district, the year, and at different parts of the same district; indeed, it is necessary to obtain the fall, from observation, for any particular district, when it is necessary to apply the results to scientific pur- poses. Elevation is also an element controlling the annual rain-fall, as found by experiments in England. At Kinfaun's Castle, Scot- land, a gauge 600 feet high, on a hill, gave 41½ inches fall of rain, while one at the base, 580 feet lower, gave only 251/2 inches. From the 23d of February, 1860, to June 6th, 1860, the fall of rain, at Dublin, was eight inches, while at the Leefin Mountains, 2000 feet high, it was 13.1 inches, showing an increase of 40 to 50 per cent. Prof. Phillips, of England, has given the following formula for "calculating the difference between the ratios of rain falling on the Digitized by Google 31 ground at any height, h, in the same place, t~the temperature of the season, and c, a co-efficient dependent upon it; then the differ- ence d is The mean height at which rain begins to form, from this formula, is 1747 feet over the ground; and at 356 feet high the depth which falls is half of what falls on the ground." The slight difference of the elevations in the district of Mary- land in which it is proposed to collect the water, will not, materially, affect the average fall of rain. From observations, in 1836, at the Maryland Academy, by Lewis Brantz, the quantity of rain that fell from July to November, inclusive, was 11.83 inches, as follows July, 1.32 inches; August, 3.13; September, 1.28 ; October, 2.55 ; and November, 3.55 inches. The quantity that fell during the same months, in 1817, was 18.13 inches, an increase of 35 per cent. The average annual fall at Georgetown, from 1819 to 1827, inclu- sive, was 38.10 inches, and the average of least fall, 31.67 inches. The following statement shows the average (by weights of periods) of the quantity of rain that fell each month, in the State of Maryland made up from the three periods of observation, viz., 1817 to 1824, inclusive, 1854 to 1859, inclusive, and for the years 1863 and 1864. The fall, from 1854 to 1859, is made up from observations annually recorded at five different points within the State, embracing the higher and lower distriets, also for the years 1863 and 1864; to which 18 affixed a column of minimum rain-fall, the former being the maximum average.

The average area of six of the principal reservoirs in the State of New York, is about five per cent of the catchment basin. The annual loss from the surface of the reservoirs, has been found to be Digitized by Google 33 one-half Qf an inch per day, or 1871 inches for the year; 49% inches of which is from evaporation, and 137.84 by filtration. These, together with the area of the pond, are assumed at 20 per cent, which, it is believed, is beyond any contingency. This leaves a net yield per acre of (69,657-20 per cent) 55,726 cubic feet. The deficiency, or quantity required beyond that furnished from natural sources, is 3880 cubic feet per minute, or 1,508,544,000 cubic feet for 270 days. Hence, the drainage area required to supply this is equal to (1,508,544,000) 27,071 acres, including area of reservoir. Ample facilities are offered for the construction of reservoirs, and receiving from this source an abundant supply of water, even upon the branches of the Big Patuxent River. The drainage area of the Cat-tail Branch (one of the branches of the Big Patuxent) was found, by Col. Abert, to equal 27,000 acres. The following shows the location and drainage area of reservoirs proposed by Col. Abert, upon the principal branches of the Big Patuxent Cat-tail Branch 27,440 acres, with a dam 50 feet high.

The same facilities are offered on the branches of the Little Patuxent River, giving in the aggregate over five times the area required, or 19,400 cubic feet per minute. 5 Digitized by Google APPENDIX A. COST OF TRANSPORTATION. The commercial value of a route depends first, upon its geograph- ical location; and second, its capacity for the movement of freight. On canals, the cost of movement depends upon the burthen of boats and the amount of lockage; on railroads, upon the grades and curves, which affect the economy of transportation. To determine the comparative cost of transportation between railroads and canals, both should be reduced to level grades; that is, the increased expense overcoming grades and curves reduced to its equivalent of level road, and the time or detentions in passing locks, to that of uninterrupted navigation, or to a uniform speed of two miles an hour. Thus, taking the speed of freight trains at 15 miles an hour, the resistance on a level is=9₁³σ lbs. per ton, and the total resistance due to a 30 feet grade lbs. As- suming the length of incline at 10 miles, its equivalent of level road would equal (22.04 of 10) 23.72 miles; hence, if the cost of transport ation over this 10 miles was 15 cents, the cost on a level road would equal (150.72) mills per ton per mile. Upon the New York State canals the detentions for lockages average feet lockage as equal to the time passing over one mile, at a speed of two miles an hour. The length of the Erie canal is 3501 miles, and the cost of transportation, exclusive of mills per ton per mile. Then the cost upon a level would equal 350}>< 21 mills per ton per mile. The actual cost of transportation, instead of freight charges, should be used for comparison between routes, as the latter fluctuate on the different routes of the same length and capacity, and on differ- ent articles, affected always by monopoly. COST OF TRANSPORTATION ON RAILROADS. The following statement shows the actual cost of transportation and freight charges, for a series of years, determined from the reports of the several railroad companies sent annually to the State Engineer and Surveyor of the State of New York.

COST OF TRANSPORTATION OF COAL ON RAILROADS. But few railroad companies keep their accounts so that the cost of this class of freight can be obtained. I herewith present all the examples I have been able to obtain from the Auditor General's report on the railroads of Pennsylvania, and other official sources. The following statement shows the average cost of transportation of freight on Railroads, other than coal, for eight years, as shown in table No. 1; also the cost of transportation of coal, the average being made from the years 1863 and 1864.

Digitized by Google 40 Cost OF TRANSPORTATION ON CANALS. From experiments in France, it was determined that when the sectional area of the canal was times, and its width 41 times that of the boat, the conditions were then the same as the move- ment of the boat in an indefinite space of water. The resistance to the movement of a boat in a canal is caused by the piling up of the water at the bow by being confined within the banks, and falling from this height, escapes along the sides, producing, by displacement, a counter action and resistance, the more considerable as the interval between the sides of boat and canal is reduced. No experiments of this nature have been made in this country, with our build or model of boats ; but it is deemed sufficiently accurate to use the formula obtained from the barges upon the Languedoc Canal, as they partake of the general build of our boats. Dubuat's formula P"=P"[(1-0.18³)X(1-q)x(-1)]; or P'= 8.46 (where q=ratio between the resistance with and without a prow ; c=sectional area of canal ; s=sectional area of boat ; P= resistance of a boat in an indefinite fluid, and P'=that experienced in a canal). This formula was found to nearly double the resistance actually experienced on the Languedoc Canal. D'Anbuisson made a series of experiments, and corrected the formula of Dubuat, so that the resistance from calculation agreed with the observed resistance. The formula, as corrected, or with sufficient exactness, was found to agree with the actual force expended. This part of the calculation embraced in the cost of transportation, covers the expense of towing, and is, upon different canals, in proportion to the resistance. The Erie Canal is taken as a basis, it furnishing the most accu- rate and reliable record of the expense of animal power as applied to towing, which has not, for several years, exceeded 25 cents a mile. The resistance, at a speed of two miles an hour, with boats of 210 tons burthen (the average now used), upon the Erie Canal, is 428 lbs. The description and dimensions of Digitized by Google 41 canals over which the products from the coal mines are transported, are given in the preceding pages of this report. The following statement shows the cost of transportation upon Canals, Bays, Rivers and Sea-borne, together with the rates added for tolls upon Coal (1861). The calculations are made upon the following basis: Age of boat assumed at 10 years, which, together with cost of furniture and interest, is divided into 2300 days; the repairs of boat and furniture 25 per cent of original cost; expense of crew $6 per day, and the cost of maintenance assumed at 40 per cent of gross receipts. The items of calculation were obtained from the most reliable sources, and, from numerous applications, found correct.) No. 5. PER TON PER MILE. NAME OF ROUTE. Length of route and canal.

The following calculation- shows the effect upon the market value of a ton of wheat and corn transported on railroads, canals and wagon roads. The cost of transportation upon railroads is assumed at 1& cents per ton per mile; canals, cents; and wagon roads, at 15 cents per ton per mile. In a ton of wheat of 2,240 pounds, there are 37½ bushels, and 40 bushels in, a ton of corn, and the value assumed in market for the former is $56.25, or $1.50 per bushel, and the latter $30, or 75 cents per bushel.

Corn, 200 miles from market, by wagon road, is just equal, in value, to the cost of transportation, while the same distance by railroad, its value is only reduced 10 cents, and by canal only six cents per bushel.

DESCRIPTION OF THE PRINCIPAL BITUMINOUS COAL FIELDS, TOGETHER WITH COST OF COAL FROM EACH, AND DISTANCES FROM MARKETS. CUMBERLAND COAL FIELDS. These mines are situated at and near Cumberland, at the termina- tion of the Chesapeake and Ohio Canal, and along the Baltimore and Ohio Railroad and its auxiliaries, the Cumberland and Pennsyl- vania Railroad, Cumberland Coal and Iron Company's Railroad, George's Creek Railroad, and Hampshire Railroad. These mines rank the first of bituminous coal fields on this conti- nent, not only in quality, but superior advantages for transportation to the great markets of the East, and facilities for mining. The workable mines are embraced within the Frostburg and Piedmont regions, lying mostly within the county of Allegany, Maryland. These mines were opened in 1842, and, although followed by new developments in the north of Pennsylvania, have always been preferred for marine uses. The coal contains a greater percentage of carbon than any found in Pennsylvania, Virginia, and Missouri, as will be observed from the following analysis: MINES. STATE. Percentage of Carbon. Evaporation per pound, (Steam 212.) Quantity of heat, by vol- ume. Percentage of Coke, by weight.

The coal lies in a trough between Davis and Savage mountains, and occurs in four principal beds, as follows: The lowest vein is five feet thick, and includes a stratum of iron one foot thick; the second is eight feet thick, and the third 14 feet, and the fourth 41 feet thick. Besides these, there is a vein six feet thick, lying 600 feet below the "big" or 14 feet vein. The quality of the lowest, or five feet vein, partakes of the nature of anthracite, and contains 85 per cent of carbon; the second or eight feet vein, yields a coal of 80 per cent carbon and 20 per cent bitumen; the third, called the "Big vein" of 14 feet, consists of two kinds, one possessing considerable lustre, and the other dull and hard, resembling cannel coal. This, the principal vein, contains 74⁻³⁻ per cent of carbon. Numerous other veins occur, alternating in the lowest portions of the deposit with slates, shales, bands of iron ore and slate clay, and the upper portions alternate with strata of shale, sandstone and limestone. Beyond the ridge called the "Backbone," is the "Younghis Garny" coal fields, with seams 20 feet thick. The following shows the number of companies and workable mines, together with the yield from each, in 1865. YIELD IN COMPANY. COMPANY. YIELD IN Tons. TONS.

" Peidmont " (opened in 1853) 2,739,623 " Total 9,349,729 " Of this quantity, the Baltimore and Ohio Railroad transported. 6,516,010 " And the Chesapeake and Ohio Canal (opened 1850) 2,833,714 " The total quantity of bituminous coal imported since its intro- duction 8,500,000 " Total quantity mined and sent to market of bituminous coal from all the mines in Pennsylvania, since 1845 6,500,000 " From this, it appears that over 35 per cent more coal has been sent to market from the Cumberland mines than from all the bituminous mines in Pennsylvania. Of this vast trade, the Baltimore and Ohio transported, in 1865, 35 per cent more than the Chesapeake and Ohio Canal. As shown in a preceding statement, coal can be sent to New York from Cum- berland, via the proposed canal, 26 per cent cheaper, and to Philadelphia 29 per cent less than by the Baltimore and Ohio Rail- road and ocean, the cheapest present route from the coal fields, except the Chesapeake and Ohio Canal and ocean. To show the practical development of the Cumberland coal region, also the present facilities and cost of getting this coal into market, a general description of the property owned and worked by the "Hampshire and Baltimore Coal Company" presents, per- haps, the fairest example. The property is embraced in two tracts, the Hampshire and Midland, 12 miles apart, embracing an aggre- Digitized by Google 55 gate area of 2212 acres, 350 acres of which is the " Big vein," of 14 feet in thickness. The Hampshire tract is situated at Piedmont, and is bounded on the north and east by the Potomac River. The succession of work- able coal veins are as follows: The Big vein (from which the coal is now mined) is 1000 feet above the river, is 14 feet thick, with two slate seams, one two inches thick, and the other 10 inches. The next vein is 2½ feet thick, and lies 60 feet below the Big vein and of a harder quality. The third vein is three feet thick, 460 feet below the Big vein. The fourth vein is six feet thick and 535 feet below the Big vein, and 595 below occurs a vein three feet thick, making, in all, an aggregate depth of about 261 feet of coal, estimated to yield 38,720 tons per acre. The coal is mined at an elevation above the railroad, and delivered directly from the chute into the cars. The tram roads are worked by eight-ton engines instead of horses. All of the coal from these mines is sent by the Baltimore and Ohio Railroad 208 miles to Locust Point, Baltimore, and there either transhipped into vessels of from 250 to 450 tons burthen, and sent by the ocean 490 miles to New York, or which is more pre- ferred, by the inland canal route in boats of 270 tons, 2281 miles to New York. The freight charges from Baltimore via the inland canal route to New York in 1865, averaged $3.00 per ton (13.15 mills per ton per mile), and in July, 1866, averaged $2.65 or 11.60 mills per ton per mile; and to Albany, from Baltimore, $3.25 or 81 mills per ton per mile; the total distance being 3881 miles. Digitized by Google 56 The following statement shows the amount it has cost the company per ton, including cost of mining, interest on investment, freight charges, salaries, office rents, insurance, &c., for the years 1861-3-4-5 and 6, from the Hampshire mines.

It embraces an area of 279 acres, 95 of which is the "Big vien" coal seam, 14 feet thick. One-half of the tract is upland, and the other bottom. The aggregate area is estimated to yield 10,000 tons per acre. The coal is mined about 300 yards from the line of railroad, and at an elevation above it, thus dispensing with the use of tram roads. The company own a fleet of 26 canal boats, of capacity to transport, without interruption, 9000 tons per month. The coal from these mines is sent 23 miles to Cumberland, by the " Cumberland and Pennsylvania Railroad" where it is tran- shipped into boats of 115 to 120 tons burthen, and sent 184 miles over the Chesapeake and Ohio Canal to Georgetown. The coal is here transhipped into vessels of 250 to 400 tons burthen, and sent 530 miles by the ocean to New York, or 418 miles by the inland canal route. Digitized by Google 57 There are many embarrassments operating against the success of this cheap and capacious outlet from the Cumberland coal fields, viz : First, the exorbitant freight charges of the Cumberland and Penn. Railroad, being 150 per cent greater than charged upon any of the Pennsylvania coal railroads; second, the unprecedented delays and detentions on the Chesapeake and Ohio Canal, together with the high rates of toll; and the last, but perhaps the greatest, is the difficulty of obtaining vessels requiring return cargoes, from the limited commerce of the district. This last embarrassment is not experienced at Baltimore, from the magnitude and variety of its commerce, and would be SO for the Chesapeake and Ohio Canal, if its terminus was brought near Baltimore as by the construction of the proposed canal; Annapolis (terminus of proposed canal), is only 38 miles from Baltimore, while Georgetown is 225 miles, and the distance, by ocean, from Annapolis, is 70 miles less to New York than from Georgetown.

Before the enlargement of the Cayuga and Seneca and Erie canals, coal, from these mines, was sent over the Tioga Railroad, 40 miles, to Corning, and there shipped into boats of 70 to 80 tons burthen, and carried to the Erie Canal markets. Since the comple- tion of the enlargement of the above canals, all the coal from the new, extensive mines of John McGee, Esq., is sent by railroad from Bloosburg, 80 miles, to Watkins (at the head of the Seneca Lake), and there shipped into boats of 210 tons burthen, and carried to Buffalo, 209 miles; Rochester, 116 miles; Montezuma, 56 miles; Syracuse, 89 miles ; Oswego, 127 miles; Utica, 145 miles; Albany, 255 miles, and New York, 405 miles, from Watkins. The character of this coal is: Percentage of carbon, 73.4; steam (of 212°) evaporated, per lb., 10.9; quantity of heat, by volume, 85; percentage of coke, by weight, .83. BARCLAY MINES. The only outlet from these mines into this State, is by the North Branch and Junction canals. The coal is brought over the Barclay Railroad, 16 miles, to Towanda, and there shipped into boats of 85 tons burthen, and sent to Athens, 15 miles; Elmira, 38 miles; Watkins, 61 miles. At Watkins the coal is transhipped into boats of 210 tons burthen for distant ports on the Erie Canal. It would be economy to tranship if the distance to be transported from Wat- kins exceeded 50 miles. The total distance of these mines from Watkins, by canal, is 77 miles; Bloosburg mines, by rail, 80 miles - the point of transhipment from both mines. These mines were not considered practically in operation pre- vious to 1854. In relation to the facilities and working condition of these mines, Col. O. W. Childs, in his report on the Chenango Canal extension, remarks, that the Barclay Railroad Company forwarded, in 1858, 16,000 tons, and in 1859, 30,000 tons, of which only 18,482 tons came into this State by canal. Their road, machinery and mines appear to be in good working order, and although the quan- tity shipped in 1859 was less than double that of 1858 (a year of the early use and interrupted employ of the road, added to the delays consequent upon seeking and introducing their coal to a new and untried market), the company being more fully prepared now, Digitized by Google 59 contemplate doing a much larger business another year, and with some additional motive power could, in a single season, send forward "120,000 tons." THE TREVORTON MINES. These mines are situated at the outer croppings of the 2d Middle Anthracite Coal District, in the vicinity of Trevorton, 13½ miles by the Trevorton Railroad to Port Trevorton, on the Susquehanna. River. Port Trevorton has a direct water communication with the New York State canals at Elmira (via the Susquehanna, North Branch and Junction canals), 200 miles; with Havre de Grace (via the Susquehanna and Penn. canals), 119 miles; with Baltimore (via same route), 173 miles; with Philadelphia (via the Susquehanna, Union and Schuylkill canals), 197 miles. There are also direct railroad communications from the mines to Binghamton (via the Northern Central, Lackawanna and Blooms- burg, Delaware, Lackawanna and Western, and New York and Erie railroads,) 184 miles; to Elmira (via the Susquehanna, Williams- port and Elmira railroads), 1421 miles; with Baltimore (via Northern Central Railroad), 141 miles, and with Philadelphia (via Northern Central, H. P. and Mount Joy, and Penn. railroads), 179 miles. LYKENS VALLEY MINES. These mines lie at the extreme northwest corner, or arm, of the 1st Southern, or Schuylkill District, and 16 miles by the Lykens Valley Railroad to Millersburg, on the Susquehanna River. Coal from these mines is shipped into boats of 85 tons burthen, at Millersburg, and sent by direct water communication to Havre de Grace (via the Susquehanna), 104 miles; to Baltimore, 158 miles ; to Philadelphia (via the Susquehanna, Union and Schuylkill canals), 182 miles ; to Elmira (via the Pennsylvania, North Branch and Junction canals), 215 miles. From these mines there are direct railroad communications with Binghamton, 187 miles; Elmira, 160 miles; Baltimore, 128 miles ; and Philadelphia, 166 miles. Digitized by Google 60 SHORT MOUNTAIN MINES. These mines lie adjoining the Lykens Valley mines, and the coal is sent to market over the same routes. DAUPHIN COUNTY MINES Also lie adjoining the Short Mountain and Lykens Valley mines, and the coal is sent to market over the same routes. BROAD Top MINES. These mines are situated between Seaton and Hopewell, on the Broad Top Railroad, 36 miles from Huntingdon. Coal is sent to Seaton by a branch about eight miles long, and at Hopewell by a branch about five miles long. The mines are seven miles long, and about three miles wide. The coal is sent by the Broad Top Railroad, 31 miles, to Huntingdon, and there shipped into boats. Huntingdon has a direct water communication with Harrisburg (via the Juniata and Susquehanna), 107 miles; Havre de Grace, 183 miles; Baltimore, 237 miles; Philadelphia (via Juniata, Susque- hanna, Union and Schuylkill canals), 261 miles; with Elmira (via Juniata, Susquehanna, North Branch and Junction canals), 320 miles; with New York city (via Juniata, Susquehanna, Union, Schuylkill, Delaware and Raritan, and Bay), 374 miles; with Albany (via Juniata, Susquehanna, North Branch, Penn. Coal Co's Railroad, Delaware and Hudson Canal and Hudson River), 412 miles. From the mines there are direct railroad communications with Baltimore, 219 miles; Philadelphia, 241 miles; New York, 313 miles; Elmira, 268 miles. PITTSBURG COAL MINES. [From Hunt's Merchants' Magazine.] The Pittsburg coal fields embrace an area of 15,000 square miles, or 9,600,000 square acres. The developed territory lies along the Monongahela, Youghiogheny and Allegheny rivers, and along the Pennsylvania, Connellsville, Pittsburg and Steubenville railroads. " There are 70 collieries along the Monongahela, embracing 12,894 acres, valued at $4,809,875, and from which the main supply is received in the markets. They give employment to 3500 hands, and it is estimated that over 13,000,000 tons of coal have been taken from these mines since 1845. The amount of tolls Digitized by Google 61 collected from shipments of coal on the Monongahela, in 1865, was over $85,000, an increase of $45,500 in two years. The coal shipped on the Youghiogheny is brought to market over the Con- nellsville Railroad. There are 22 collieries along this road, that embrace an area of 3929 acres, valued at $1,000,000. They give employment to 900 men. Two million tons (valued at about $5,000,000), have been transported over the Connellsville road in the past five years. " There are 12 collieries in the hills surrounding the city, covering an area of 1570 acres, valued at $1,250,000, and which furnish employment to 1500 men. Several of the rolling mills in Sligo and Birmingham are supplied from collieries immediately above them. 'These city mines' furnish nothing for outside markets. They yield a yearly product of 3,000,000 bushels, all of which is consumed by our rolling mills and iron works. The collieries that border the Pennsylvania Railroad from this city to the foot of the mountain' are not usually classed as in Pittsburg measures, though the most valuable lie nearest this city. The bulk of the trade goes East. Those immediately in the vicinity of the city cover about 1000 acres all told, employ 400 hands, and send to this market an annual average of 4,500,000 bushels. The Allegheny Valley collieries, though neither very numerous nor productive, extend over a large tract of territory, perhaps 1500 acres, and employ about 500 hands. From these collieries, the Allegheny Valley Railroad brought to this city last year about 70,000 tons. These coal lands are considered exceedingly valuable, and but for the limited facilities for transportation at the very season when their product is most called for, they would no doubt be extensively worked. " The exact depth and value of the coal measures around Pittsburg it is impos- sible to figure. But the upper seam alone averages eight feet in thickness. An industrial writer figures the contents at 53,516,430,000 tons, which, at $2 per ton, would be worth $107,032,860,000. The total number of collieries at pre- sent in operation in the Pittsburg coal field, embracing the whole range which we have described, is 103 ; hands employed, 6424; value of lands, $7,589,700; value of annual coal product, $5,000,000." The length of the Monongahela navigation, from Pittsburg to New Geneva, is 82 miles; and the Youghiogheny navigation, from Mc- Keesport to West Newton, 18 miles. The most direct route to the Philadelphia market for the Pitts- burg coal, is via the Pennsylvania Railroad, 355 miles; and to Chicago, via the Pittsburg, Fort Wayne and Chicago Railroad, 4671 miles. Digitized by Google 62 The following statement shows the length of railroads and the freight charges on coal per ton per mile, over the trunk lines and branches leadin from the Pittsburg mines, for 1865.

The burthen of boats over this 461 miles of canal, average 90 tons, and the cost of transportation, for 1861, averaged 11.86 mills, and for 1865, 19 mills per ton per mile. The cost of transportation over the Pennsylvania Railroad averaged, for 1861, 20 mills, and for 1865, 26.60 mills per ton per mile. The cost of transhipments, in 1861, averaged eight cents per ton, and for 1865, about 16 cents.

MARYLAND-ITS CLIMATE, SOIL, PRODUCTIONS AND PHYSICAL CHARACTERISTICS This State was named after Queen Henrietta Maria, and was the first English province settled in America, in 1632. There were no slaves imported after 1769, and was prohibited in 1783. The Irish and Germans settled principally in the western counties. In 1665 the population was 16,000, and in 1830 there were 291,100 whites and 156,000 blacks. Baltimore was founded in 1730 ; Annapolis was founded in 1683, under the name of Proctor's Landing; and was made the capital in 1692, and incorporated a city in 1708. St. Mary's was the first set- tlement made in the State. The State boundary is very irregular, and embraces an area of 7,680,000 square acres, 5,438,000 of which is land. The Chesapeake peninsula has an area of about 3,200,000 square acres, and is about 180 miles in length from Elkton to Cape Charles. The eastern shore is less broken than the western, and both are deeply furrowed by the action of streams. The neck between the bays joining the main shore, is about 12 miles wide, and expands to 70 miles in width, and again contracts to 10 miles in a distance of 60 miles. Its general elevation is about 220 feet above tide. Chesapeake Bay embraces an area of about 2,240,000 square acres, or one-quarter the area of the State. The length of the bay, from its mouth to Havre de Grace, is 190 miles from south to north. The width of its mouth, between capes Charles and Henry, is 11 miles. Its average width below the mouth of the Potomac, is 14 miles; opposite, 10 miles, and above, eight miles; throwing off, on both sides, numerous arms, forming beautiful and capacious harbors, deep and navigable for large class of vessels. A sand bank, called the "middle ground," covered with from 10 to 18 feet depth of water, lies midway between the capes, leaving broad and deep chan- Digitized by Google 65 nels each side. The area of country drained by this bay is over 44,800,000 square acres, upon which there is annually deposited from rains, an average of 224 million cubic feet per minute, 751 million cubic feet of which reaches the bay.

The depth between its mouth and Washington, is from 18 to 120 feet; and the tide flows to George- town, 128 miles from its mouth. The distance, by air line, from Washington to the mouth of the Potomac, is about 72 miles. SOIL. The character of the soil in the region of the proposed route of the Chesapeake Bay and Potomac River Tide-water Canal, through the counties of Anne Arundel and Prince George, is of the richest and most durable kind, and one of the finest tobacco districts in the State. The soil is composed of light silicious loam, mixed with clay in proper proportions for culinary plants, strawberries and cereals. It is finely pulverized, yet not sandy; mixed in due proportions with green-sand-marl on the surface, showing great fertility, productive- ness, and inexhaustible, even under indifferent cultivation. The surface, in every direction, is undulating, the elevations not abrupt or rising above a general level, but graceful and easy for cul- tivation and for perfect drainage. These remarkable characteristics of soil and rural beauty are more applicable to the eastern half of Prince George's county. Material for enriching the poorer sections, is everywhere abundant, from the masses of oyster shells at the mouths of streams, from six to eight feet deep, called "Indian shell banks," together with the immense beds of shell-marl, in no respects fossilized, and the oyster rocks of Sinepuxent Bay. When the new system of labor is successfully introduced into this portion of the State, the land can be made to yield 25 per cent more than the average of the best agricultural districts of the State of New York; and, the soil being light and the drainage perfect, can be worked from 15 to 20 per cent less in expense. It is not unusual for farmers to raise three crops a year. The existence of a belt of the upper secondary series, extending Digitized by Google 67 across the State, south of Parr's Ridge, through the counties of Cecil, Kent, Anne Arundel and Prince George's counties, has been found of the same age as the New Jersey green-sand-marl. This eastern plain consists of tertiary beds of clay and sand, in some places highly fossiliefrous, and in others quite destitute of organic remains. The beds of shell-marl occur in the central, eastern and lower western counties-sometimes at the surface, and sometimes covered by a stratum of sand and gravel from 10 to 30 feet thick- consisting of shells of different kinds imbedded in clay and cemented together by a calcareous cement. The shell-marl deposits through large portions of the State, were from the closing of immense bays, such as the process now going on of Sinepuxent Bay, which is four miles wide and thirty long. West of this plain extends a belt of primary rocks of the stratified series, comprising gneiss, mica-slate, hornblend rock, limestone, ser- pentine chlorite and clay slates, &c., and passing on the west side into rocks of the Grauwacke group. CLIMATE. The following Meteorological Table shows the comparison between the temperatures of the States of New York and Mary!and, also the rain- fall, which clearly illustrates the superior advantages of the latter for culinary plants, grapes and strawberries. The observations for the State of New York were taken at eighteen different localities, and for Maryland at five places. STATE OF NEW YORK. STATE OF MARYLAND. MONTH. Av. 1854 to 1859.

The same for the State of New York, summer mean 67°.5; July, 72°.6; August, 69°.2, and September, 59°.5. As to the quantity of rain, it is about the same ; and, from the temperature, the seasons of Maryland precede New York about five weeks. PRODUCTIONS. The staples of the eastern shore are Indian corn and wheat, and the same articles, with tobacco, are the staples of the western shore. Rice and cotton are raised to a limited extent in the south- ern counties, and the castor oil bean found to thrive. Prince George county yields the greatest quantity of tobacco of any in the State. In 1860, there were in Maryland over three million acres of improved land, and 1,833,300 of acres unimproved. The cash value of farms was estimated in 1860 at $145,973,600, and for farming implements over four million dollars. For the same year, the orchard products were estimated at over one-quarter of a million, and garden products over one-half a million dollars. The quantity of tobacco raised in 1860 was nearly 40 million of pounds, and the estimated value of live stock, for the same year, was 142 million dollars. The capital invested in real and personal estate was, in 1860, nearly 52 million, and the value of annual products, 421 million dollars. The taxable value of real and personal property of the State, in 1865, was 2781 millions, and in 1864 it was 2854 mil- lion dollars, showing a decrease of 71 million dollars, caused by the deduction of all slave property. Epsom salt is also produced from magnesian earth, associated with serpentine also, yellow chrome; blue vitriol from the black earth of Monocacy Valley, red and yellow ochre, copperas, fire-brick, pottery, stone and glazed wares. Iron, coal and lime are the staples or constitute the mineral wealth of the western counties; also chro- miferous ores near Baltimore and Cecil. Porcelain earth, lime, marble, manganese and copper ores, occur in this tract. In the counties of Dorchester, Caroline, and Worcester, is found the bog iron, and in the belt forming the western plain, hone ore, brown ore, and brown oxides. Among the useful minerals found in Prince George and Anne Arundel counties, are the valuable clays for the Digitized by Google 69 manufacture of stone and glazed wares, and in Cecil county is found materials for fire-brick, alum earth, copperas ore, red and yel- low ochres. In the valley beyond the Blue Ridge, is found the pipe or limestone ore and the coal measures of Alleghany county. In Mr. Trimble's report on the survey of the Potomac and Balti- more Railroad, 70 miles long, he estimated the gross revenue from local freight at $271,600 per annum, assuming that all the products of the country, for five miles in width, each side of the line, would pass over this road. On looking over the products of the State, I think this estimate a fair one. Assuming the same basis of calculation, and increasing the area or width by the difference in the cost of transportation, (which is at least one-third less per ton per mile than upon the railroad), and it makes a stripe each side of the proposed canal about 71 miles wide. Using this as a basis, and making the allowance for difference in distance and rates of transportation, and the gross revenue received from tolls on local trade on the proposed Chesapeake Bay and Potomac River Tide-water Canal would be $48,500 per annum.

Many of these vessels, of too great capacity for the Delaware and Raritan Canal, take the sea from New York to Norfolk, and then the inland route to Newbern and other points along the coast. During the last four months of the season of 1865, over 40 steamers bound from New York, Phila- delphia, Portland, Boston, and Baltimore, to Charleston, Savannah and the West Indies, availed themselves of this inland route. Before Digitized by Google 71 the blockade of the southern ports in the late war, over 300 vessels of all classes were occupied with the commerce passing over this canal.

CHESAPEAKE AND DELAWARE CANAL. This canal is 131 miles in length, and connects the heads of Chesapeake and Delaware bays. The prism is 46 feet wide on bottom, 66 feet at surface water, and 91/2 feet deep. The locks 220 feet in length between quoins, 24 feet wide, and four in number, Digitized by Google 72 overcoming a rise and fall of 30 feet. The capacity of the canal will pass boats of 300 tons burthen. The summit level is supplied with water by steam power. It is accomplished by two engines, attached to a wheel 38 feet in diame- ter, revolving in a reservoir, that raises the water in curved radial compartments, discharging it at the shaft, 13 feet above the sur- face, of lower pond. By this method 6,000,000 cubic feet is raised and discharged into the canal every 24 hours, equal to 4166 cubic feet per minute. To operate it requires two enginemen, four fire- men, and nine tons of coal every 24 hours, at an annual expense (1866) of $31,618.61.

In 1866, 108,818 tons of anthracite coal passed westward, and 39,136 tons semi anthracite and 120,433 tons of bituminous coal passed east- ward. Mr. H. V. Lesley, the secretary of the company, informed me that over 70,000 tons of anthracite coal passed over this canal in 1865, consigned to the District of Columbia. The total coal tonnage of this canal was, for 1865, 360,781 tons, and for 1866, 268,387 tons. The construction of this canal cost, up to 1866 (including new machinery for raising water, $31,515, and old feeder, $110,925), $3,271,127, equal to $242,306 per mile, and without the old feeder (now dispensed with), $234,090 per mile. The cost of repairs and management, exclusive of cost of new machinery, for 1865, was $98,725.38, equal to $7313 per mile; and for 1866, it was $127,668.08, equal to $9457 per mile. The gross amount of tolls collected, in 1865, was $424,312, equal to $31,430 per mile; and for 1866, $350,939, equal to $25,995 per mile.

DELAWARE AND RARITAN CANAL. This canal is 43 miles in length, from Bordentown, on the Dela- ware River, to New Brunswick, at the mouth of Raritan River. The size of prism is 75 feet wide at surface of water, 47 feet wide on bottom, and seven feet deep. The locks are 18 in number, 110. feet in length, between quoins, and 24 feet wide, overcoming a rise and fall of 146 feet. The burthen of boats equal 270 tons, and the motive power used upon the canal is steam towage. The canal is owned by and embraced in the "Camden and Amboy Railroad and Transportation Companies." The distance. from Port Richmond (east limit of Philadelphia) via this canal, to New York, is 100 miles, as follows: Port Richmond to Bordentown 23 miles; Delaware and Raritan Canal 43, and New York Bay' 34 miles. The following shows the coal trade of the canal, for the year of 1865: Coal from Schuylkill, in boats 664,5381 tons.

The receipts of the Delaware and Raritan Canal Company were one million, one hundred and twenty-eight thousand and seven dollars and thirty cents ($1,128,007.30), and the expenses were three hun- dred and seventeen thousand, five hundred and seventy-seven dollars and seventy-five cents ($317,577.75), inclusive of transit duties. Those duties which accrued from the canal were sixty thousand, nine hundred and ninety dollars and ninety-nine cents ($60,990.99), and those paid were fifty-four thousand, five hundred and ninety-eight dollars and eighty-four cents ($54,598.84). There are employed upon the canal, mainly, 24 steamers and five propeller tugs. I have been unable to obtain the cost of this canal, and have assumed it the same (although far inferior in the character of con- Enlarged fact length Digitized by Google 75 struction, but about the same in capacity) as the average of the Cayuga and Seneca, Oswego and Erie canals, equal to $80,000 per mile. This makes the total cost of construction $3,440,000, and the annual net revenue on same for 1865 equals 24 per cent, and the cost of management and repairs 28 per cent of the gross receipts. The average rate of toll upon the gross tonnage is about 1π³⁻ cents. The toll upon coal in 1861 was one cent, and in 1864, 1100 cents per ton per mile.

(See Appendix A for the cost of movement over canals.) Cost of motive power 18 cents per mile. " " boat and furniture, with interest on the same 4.345 " " " " repairs 0.638 " " Expense of crew 15.500 " " Total actual cost of movement, exclusive of tolls 38.483 " " which, divided by the burthen of boat (120 tons), equals mills per ton per mile, exclusive of profits to carrier, or toll. The actual rate charged for 1861, exclusive of tolls, was 51 mills per ton per mile, and including tolls, 81 mills. The cost of repairs and management is assumed at the average for canals, 30 per cent of gross receipts from tolls, and we have the following, reduced to a level canal, and including the cost overcoming lockage: Actual cost of movme't, mills pr. ton pr. mile 3.2 for lockage, and 2.49 for a level.

The actual cost of moving freight over railroads, embraces expenses of maintaining roadway and real estate, cost of repairs of machinery, and cost of operating the road. Applying the same basis for the Chesapeake and Ohio Canal, we have: Repairs of rolling stock 0.638 cents per mile. Cost of motive power 18.000 " " " " " crew and maintaining canal 34.000 " " " Total cost of transportation, exclusive of tolls 52.638 " " " equal to mills per ton per mile upon the basis of the actual cost of railroad transportation, and the lowest rate to which the cost of transportation over the Chesapeake and Ohio Canal can be reduced, and the total receipts per ton per mile, including profits to stockholders and carriers, for the year 1861, as follows: Digitized by Google 78 Actual cost of transportation, including expense of crew, repairs of boat and canal 4.38 mills. Profits to carrier 2.30 " Net toll (1863) or profits to stockholders 2 " Total rate of freight charges 8.68 " which may be taken as the maximum rate; hence, the Baltimore and Ohio Railroad, to compete with the Chesapeake and Ohio Canal, must make the actual cost of transportation equal to 4100 mills per ton per mile, and freight charges 8% mills, based upon [prices pre- vious to 1862. Assuming that all conditions were equal, this could not be done, as the Baltimore and Ohio Railroad cost, exclusive of equipment, $14,383,734 more than the Chesapeake and Ohio Canal, and the percentage of expense on the gross receipts for repairs and management, has never been below that experienced upon the Chesapeake and Ohio Canal. It is evident that seven-eighths of all the coal from the Cumber- land mines should pass to tide-water over this canal, and the only additional facilities required to secure this trade is the control, by the canal company, of ráilroad lines leading from the canal to the mines, and the shipments, via ocean, to be made from Annapolis instead of Georgetown, which would secure in the first a reduction in the cost of coal of 82 cents per ton, and in the latter a ready command, at all times, of vessels requiring return cargoes, from its proximity to Baltimore, and a reduction of 52 cents per ton in freights. The following shows the rates of freights actually charged, including tolls, over the Chesapeake and Ohio Canal; also; via ocean, from Georgetown to New York; also, over the Baltimore and Ohio Rail- road and ocean, for the years 1861-4-5 and 6 : DISTANCE, IN MILLS PER Tox PER MILE.

The average rate of toll, upon gross tonnage, was 457 mills per ton per mile, and the freight charges, including tolls, averaged, for the season, 11½ mills, being for down freight, and for up freight. The cost of repairs and management was 23 per cent of gross receipts. SKETCH OF THE ERIE CANAL, SHOWING COST OF TRANSPORTATION. The following condensed sketch of the Erie Canal, showing the gradual reduction in the cost of transportation, and the method pursued in the foregoing calculation, may be of interest to many not conversant with its general character as connected with this subject: Erie Canal. - The construction of the Erie Canal was com- menced July 4th, 1817, and completed October 26th, 1825, at a cost of $7,143,789 19,255 per mile. The dimensions were as follows: Width at surface, 40 feet; at bottom, 28 feet, and four feet depth. The locks were 90 feet in length between quoins, 15 feet wide. The average burthen of boats used was 50 tons. The length of canal, before its enlargement, was 362 miles, from Albany to Buffalo. The cost of transportation, in 1830 (the earliest record preserved), was, for tolls cents, and for tolls and freight 51 cents per ton per mile, from Albany to Buffalo; and from Buffalo to Albany, the tolls were about 1½ cents, and tolls and freight 2½ cents per ton per mile ; making an average upon the tonnage to and from tide- water (which was five to one)=three cents per ton per mile, includ- ing tolls. The enlargement of the Erie Canal was authorized May 11th, 1835 and accompanying the estimate of its probable cost, was one showing, that by the proposed enlargement the cost of transportation would be cheapened 50 per cent. The cost of transportation, in 1835, was, from tide-water, for tolls, cents, and for tolls and freight 4x½ cents per ton per mile; 2 Digitized by Google S1 and to tide-water, for tolls nine mills, and for tolls and freight 14 cents; making the average cost upon the tonnage to and from tide- water (which was about 5&4 to one) 21% cents per ton per mile, including tolls. The enlargement was practically completed in 1859, but the construction account was not closed until April 10th, 1862. The total cost of construction, including the original canal, was $42,952,997, and including land damages and interest on loans, $55,187,890. The present size of this canal is 70 feet surface, 56 feet at bottom and seven feet depth, and 3501 miles long. The locks are 110 feet in length between quoins, and 18 feet wide in the clear. The average burthen of boats now used is 210 tons. The cost of transportation, in 1862, averaged, from tide-water, for tolls four mills, and for tolls and freight 7 π¹σ mills per ton per mile and to tide-water, for tolls six mills, and for tolls and freight cents per ton per mile; making an average upon the tonnage to and from tide-water (which was as eight to cents per ton per mile=a reduction of 50½ per cent from 1835. The aggregate of the carrier's charges, in 1862, averaged mills, and the tolls mills per ton per mile. The total cost of repairs and management of the Erie and Champlain canals for 1864, was $578,330, equal to $1366 per mile, and the gross receipts from tolls, $4,042,092, equal to $9716 per mile. The total tonnage of these two canals was 3,382,582 tons. The cost of repairs and management for 1864, was 14½ per cent of the gross receipts, and paid a net revenue of 7% per cent on a capital of $45,250,000, equal to the total cost of these two canals. The actual cost of movement, calculated upon the method adopted in this report, is as follows: Expense of crew (1 captain at $60 per month, 2 hands, $45 each 1 cook, $30 per month)=$6 per day, by 81/2 days $51 00 Cost of boat and furniture, with interest for 10 years, divided into 2300 days-total per day $2.50, by 81 days, the time of passage 21 25 Repairs of boat, 25 per cent of cost=38 cents per day 3 23 Towing 25 cents per mile, by 3501 miles 87 62 Total cost of passage $163 10 Actual cost, including lockage, per ton per mile (210x350) 2.21 mills.

Profits to carrier 3.93 " " " Net toll 3.57 " " " Total cost upon basis of receipts of R. Rs. 10.60 " " " Hence, railroads, to compete with the Erie Canal, must reduce the actual cost of transportation to three mills, and receipts to cents per ton per mile. The total number of boats registered up to 1854, was 2126 upon the New York State canals, and the total number registered from 1844 to 1864, inclusive, was 8943 ; making total number 11,069 boats. The total number registered from 1854, to 1864, inclusive, was 5427, and the number registered in 1864, was 399, the greatest number of which was 210 tons burthen. Allowing two horses to each boat, the total cost of equipment of the New York State canals in 1864, was about $18,000,000.

From the foregoing, the average receipts of the New York Cen- tral were cents; Erie, and New York canals cents per ton per mile, or the average of both roads 2% times the cost upon the canals. The total value of the total tonnage of the New York State canals for 1864, was $274,500,000. The value of total tonnage arriving at tide-water from the Erie and Champlain, was $145,500,000, and the value of wheat and flour which came to the Hudson River for this year, was 48,333,333. The total cost of repairs of the New York State canals for 1864 was $846,624, equal to $943 per mile. BALTIMORE AND OHIO RAILROAD. This was the first railroad opened for passenger traffic in this country, in 1830, and the second upon which locomotives were first used, in 1831. The first locomotive was built at West Point, and weighed four tons, with a maximum speed of 20 miles an hour. Since 1850, the Chesapeake and Ohio Canal has been its only competitor in the transportation of coal from Cumberland to tide- water. From 1860 to 1865, inclusive, 2,375,256 tons of coal was Digitized by Google 84 transported over this road to Baltimore, and 1,310,797 tons over the Chesapeake and Ohio Canal. In 1865, 424,316 tons was transported over the former and 343,200 tons over the latter. The following analysis of this road is from the annual report of the company for the year 1863. The report is very deficient in detail, omitting to classify the expenses and receipts for passenger and freight traffic, and to give the number of tons of freight moved one mile. The desired results are, however, approximately obtained by comparison with other railroads for the same year. Length and cost of roads owned by the company. CosT OF ROADS. LENGTH. MILES. TOTAL.

The same for all the New York State railroads, for 1863, was 601 per cent. Upon 13 of the principal railroads in New York, it averaged 591 per cent, 41 per cent greater than the Baltimore and Ohio road. The net revenue on the cost of main stem, is 16 per cent; northwestern Virginia per cent, and Washington Branch 421 per cent, mak- ing the average annual net revenue, for 1863, on total cost of road and equipment of 17 per cent.

The lowest cost of machinery department for the New York roads in 1856, was 38.10 cents per mile run, fuel being 161 cents. There were 79 engines in use upon the "Northern Central Rail- way" in 1863, varying in weight from 32,000 lbs. to 63,000 lbs. The tractive power of the smallest is equal to 3780 lbs.; of the average, 10,967 lbs., and the largest, 12,936 lbs., with a working pressure of steam on cylinder of 70 lbs. per square inch.

The trial was continued for several months over 96 miles of the Erie Railway, and the superintendent of the motive power, Mr. F. Leech, stated in his report for that year, " that it proved 47⁻³⁻ per cent cheaper than wood, reckoning the cost of the former at two dollars and seventy cents per ton, and the latter at three dollars per cord, all delivered in the tender." The result of this experiment shows, that when wood cost three dollars per cord, coal was worth five dollars and seventy cents per ton.

These experiments clearly demonstrate that, by the use of coal upon railroads instead of wood, one-half the cost of fuel is saved, and this item alone, upon all the railroads in the United States, would amount to over 11½ millions of dollars annually. Cost of Transportation, and Effect of Grades on same. As determined in the forepart of this analysis, the cost of man- agement on the Baltimore and Ohio Railroad was 341 per cent of the gross receipts over all the roads operated by the company, and per cent on the main stem. The same upon 13 of the principal railroads in the State of New York was 591 per cent, equal to 41 per cent greater than the former of aggregate lines, and 50 per cent above the cost of the former for the main stem. The actual cost of transportation on the 13 New York roads was 12 Digitized by Google 90 184 cents, and receipts cents per ton per mile; hence, the actual cost of transportation in the aggregate on the Baltimore and Ohio Railroad for 1863, was cents, and main stem cents per ton per mile. The receipts, to realize the same profit as upon the New York roads, should have been, for the aggregate, 17 cents per ton, and upon the main stem, 1100 cents per ton per mile. The rates actually charged in 1863 for the transportation of coal on the main stem from Piedmont to Baltimore, was 1800 cents per ton per mile. The relative advantages of different railroads, depends upon their grades and curves, which affect the economy of transportation; and to effect a comparison, should be reduced to level lines requiring an equal expenditure of power. Experiments were made on an extensive scale in England, as also upon the Erie Railway, to find the resistance due to grades and curves, at different speeds; also, the resistance on a level. The formula obtained by D. K. Clark, a distinguished engineer and author, for the total resistance to the motion of a railroad train upon a level was +8-R where V= velocity in miles per hour, and R=the resistance in lbs. per ton. The resistance due to any grade is independent of all other consid- erations, and determined by the formula 2240 5280 The resistance due to curves was determined by Mr. McCollum, at one-half lb. per degree of curvature per 100 feet, or for a 4° curve two lbs. per ton. Mr. Clark estimated the resistance due to curves of one mile radius and under, at lbs. per ton. "The general practice of some engineers," remarks Mr. Vose, "in equating for curvature, is to add one-fourth mile to the measured length for each 360° curvature, disregarding radius." The average of the three experiments on curves gives 1140° curvature as equal to the expense in passing over one mile of straight level line. The chief items affected by grades are fuel and first cost of loco- motives. In doubling the work done by engines, the cost of fuel is only increased 90 per cent. In descending grades, 25 feet per mile is sufficient to allow the train to roll down by the force of gravity alone, and any more than this is of little use; hence, in equating for descending grades, one mile should be deducted for each mile of 25 feet grades. Digitized by Google 91 The following table shows the resistance, in lbs., per ton, and for 100 tons, at speeds of 10 to 100 miles an hour on a level road, calculated from the formula 171+8; also, the resistance per ton upon grades of 10 to 100 feet per mile, calculated from the formula 2240 X grade the latter being independent of the former: POUNDS RESISTANCE.

To lead well, the truck of an engine should have at least five tons placed on it.

The following are the maximum grades on the several divisions of the Baltimore and Ohio Railroad: Baltimore to Harper's Ferry 80 miles; maximum grade, 82 feet. Harper's Ferry to Cumberland 98 " " " 40 " Cumberland to Raccoon 88.2 " " " 116 " Raccoon to 148 miles 60.5 " " " 40 " 148 miles to Wheeling 51.3 " " " 80 " The relative length of each division, reduced to level roads, is as follows - assuming, from the general rule, that the greatest load that can be taken over any section is limited by its maximum grade, and the following shows the relative length of each division reduced to level roads : Digitized by Google 93 80 X (93+3+3) = 379.20 98. X (9.3+9.3) = 275.30 88.2 X (9.3+9.3) = 555.66 60.5 X (9.3+17) = 170.61 51.3 X (93+93) = 238.54 Measured 378 miles; equated 1619.31 miles, equal to 4⁻³₀ the actual length, or requiring times more expenditure of power than if the road was level. The actual cost of transportation over the main stem was found to be mills per ton per mile; hence,. the cost, reduced to a level, or upon a level road, would equal (9.2*3.31) 2114 mills per ton per mile. This is a very flattering result, and proves beyond question, that the adaptation of power to grades on this road is perfect. As demonstrated in a former statement, the actual cost of trans- portation over the Chesapeake and Ohio Canal was 4TOT mills per ton per mile, including repairs of boats, furniture and canal, and cost of movement; or upon the same basis as over the Baltimore and Ohio Railroad, without profits to carriers or stockholders. The cost, reduced to a level canal, would be (19.374.33) mills per ton per mile, equal to 37 per cent greater than the Baltimore and Ohio; showing that if both were level, the road could carry freight at rates 37 per cent lower than the canal; but by the increase of grades and cost of overcoming them, the canal can carry 50 per cent lower than the railroad. The following are the characteristics of the New York and Erie Railroad. The divisions are made to correspond with those of the Baltimore and Ohio. 1st 107.70 miles of level road. 2d 93.06 " with maximum grade of 10 feet. 3d 99.00 " " " " 20 " 4th 97.63 " " " " 50 " 5th 49.54 " " " " 70 " The equated length of the above divisions are as follows: 107.70 X (level) = 170.70 93.06 X (9.3+9.3) = 135.78 99.00 X (93+93) = 189.09 97.63 X (9.3+21.3) 320.22 49.54 X (9.3+9.s) = 209.05 Actual 446.93 miles; equated 961.84 miles, equal to 215 times the length, or requiring more than double the expenditure of Digitized by Google 94 power than on a level road. The actual cost of transportation over the Erie Railway, in 1863, was 91 mills per ton per mile; hence, 9.5x446.93 the cost, reduced to a level, would equal 961.84 per ton, or 51 per cent greater than the Baltimore and Ohio Railroad. If the foregoing calculations are correct, the cost of management on the main stem of the Baltimore and Ohio Railroad should be 51 per cent lower than on the Erie. The cost of management of the Erie, in 1863, as stated in the annual report of the State Engineer and Surveyor, was ; hence, for the Baltimore and Ohio. it should be per cent, which corresponds with the amount as stated by the company in their report for 1863. The business of the Baltimore and Ohio road was performed by 221 engines of all classes, in 1863, and upon the Erie with 249 engines of all classes. The total miles run by the former during the year was 3,730,258, and by the latter 5,818,779, or 371 per cent greater. The following calculation shows the cost of overcoming grades from 10 to 116 feet per mile, based upon the actual cost of transportation over the Baltimore and Ohio and Erie raïlroads, under the following con- ditions: Weight of engine 73,700 lbs., distributed on eight drivers ; weight of tender, 40,000 lbs. ; capacity, 1747 gallons; diameter of cylinder, 181 inches ; stroke, 23 inches ; diameter of drivers, four feet, with a steam pressure of 75 lbs. per square inch, and at a speed of 15 miles an hour.

SKETCH OF FORMER SURVEYS FOR THE EXTENSION OF THE CHESAPEAKE AND OHIO CANAL TO BALTIMORE. 1st. DR. WM. HOWARD'S SURVEY, 1826. Dr. Howard, a distinguished civil engineer, made a survey in 1826 for a canal from Georgetown to Baltimore. He made the total length 44 miles, and lockage of 262 feet; estimating the cost at $3,530,000. The size of canal adopted was 33 feet on bottom, 48 feet at surface of water, and five feet deep. There were to be 38 locks, overcoming 130 feet of ascent, and 164 feet descent. The summit level was fixed at 146 feet above tide, and was over 12 miles in length. Upon this line there were three extensive cuttings: 1, of the ridge, between the Patapsco and Patuxent, greatest depth 64 feet, and extending 21 miles; 2, of the middle ridge, between the two branches of the Patuxent, 74 feet depth and 18 miles long 3, the ridge between the Patuxent and Potomac, of 72 feet greatest depth, and 2½ miles in extent. The aggregate expense of these cut- tings, he estimated at $1,200,000. The length from Georgetown to Bladensburg was 91 miles, with two locks descending 18 feet; expense $480,522, including aque- ducts over Rock and Tiber creeks and the Eastern Branch. From Bladensburg to summit level, 91 miles, with 17 locks ascending 130 feet; expense $388,903, including aqueducts over Northeast and Paint branches. For a supply of water, the Doctor contemplated diverting the waters of the two Patuxents, with several smaller streams, for the summit level, and, in descending toward the Potomac, receive the waters from Northeastern Branch, also the Northwestern; and from Bladensburg, to meet the waters from the Potomac. The streams having been gauged during a season of unparalleled drought, the report affirms that a canal laid down and constructed in the manner proposed, could be amply supplied with water, and Digitized by Google 96 was entirely practicable; and, from examinations, that no canal com- munication from Baltimore to the Potomac could pass northwest of the line selected, consequently that all the routes proposed through Montgomery county were impracticable The ridge between the two Patuxents, on the most southern route suggested by Dr. Howard, was found but 135 feet above tide, near a school house; and that the depression on Snowden's Ridge, on the land of Zelic Duvall, was 155 feet above tide. He made the summit level 21 feet above the depression between the two Patuxents, and but nine feet below the summit of Zelic Duvall's. Dr. Howard made accurate gauges of the streams, and found a natural supply of 2411 cubic feet per minute. The Doctor's route was along the valley of the Northeastern Branch to Bladensburg; thence crossing the Eastern Branch and continued along its right bank to near Benning's Bridge; thence to the north of the capitol and city hall to Rock Creek, and over this stream to the line of the Chesapeake and Ohio Canal. It was calcu- lated to feed the canal to the Eastern Branch from a large basin or reservoir, at the termination of the Chesapeake and Ohio Canal, which was 25 or 30 feet above tide. Going east, the line continues along the Eastern Branch, and crosses it by an aqueduct immediately below the bridge at Bladensburg. Passing through this town, it follows, first the valley of the northern Eastern Branch, then Pinery Branch, crossing the turnpike road one-quarter of a mile south of Vanesville. A little beyond this, the line attains its highest eleva- tion. CoL. ABERT'S SURVEY, IN 1838. Col. Abert's was the last survey made for a canal from Washing- ton to Baltimore. He pronounced the "Singanore and Seneca routes" entirely impracticable, and passes a general review of all former surveys. He declared the "Brookville route" practicable, with a due supply of water. The summit level of this route was 16 miles long, connecting on one side with the Seneca, at the mouth of " Weststone Branch," and on the other with the Patuxent, at the mouth of Hawling's River. The summit level was fixed at 375 feet above mean tide, and 120 feet below the "Seneca route," and from eight to nine miles south of it. This route required two tun- Digitized by Google 97 nels, the total length of which was over three miles. The line admitted of using the waters from six reservoirs, with a united drainage area of 64,044 acres. (For location of these reservoirs, see appendix C.) Col. Abert made the total development of feeder lines, from the reservoir, 15 miles in length, uniting, however, so as to form but two points of connection with the summit level. He estimated the yield from these reservoirs (assuming 29 inches fall of rain, and that one-third would be collected) at 2,247,199,497 cubic feet of avail- able water. He then shows the quantity of water required, as follows: To fill the canal 909,774,500 cubic yards. Leakage at locks 1,999,995,000 " Filtration and evaporation 18,195,490,020 " Lockage water 26,666,666,000 " Loss from feeders 11,376,199,999 " Half-inch loss per day from reservoirs for the year 17,206,399,000 " Making a total of cubic yards 76,354,524,049 or " " " feet 2,061,572,148 Leaving a surplus of cubic feet 185,627,349 And he remarks, that with this result the Brookville route may be considered practical. Col. Abert made a supplemental report, dated February 11, 1839, that the whole length of the canal, as laid down by him, was about 70 miles; and that an actual survey had been made of 21 miles; estimating the cost of same at $116,700; but that no estimate had been made of the remaining 49 miles, as this would show a cost of more than one-half million dollars per mile. REPORT OF CHAS. B. FISK AND GEO. W. HUGHES, 1837. The report of these gentlemen embraced examinations more especially to the facilities for supplying any canal across this portion of Maryland with water. They estimated the drainage area of the Patuxent valley at 64,000 acres. They estimated the flow of streams at 2400 cubic feet per minute, and doubted the capacity of natural resources for supplying a canal from Washington to Balti- more with water. 13 Digitized by Google 98 The following statement was submitted by them, showing the character- istics of the route surveyed: LENGTH.

Mr. Trimble's report is a review of reports on former surveys, and each route analysed. The " Westminster route," which ascends the Patapsco and its north branch to Westminster, thence descends by the valleys of Little Pipe Creek and the Monocacy to the Potomac, was deemed, by Mr. Trimble, impracticable. SINGANORE ROUTE was estimated to cost $8,810,000-$100,000 per mile. The natural summit at Grimes' tobacco house, in a depression of Parr's Ridge, was found 7661 feet above tide. The summit level was assumed 2381 feet below this point, or 528 feet above tide; which involved the construction of a tunnel three miles long, and cuts at extreme- ties of same of 50 feet. The quantity of water required above that furnished from natural flow, required the construction of a reservoir, the drainage area of which was fixed at 16,640 acres, which was estimated to yield (assuming one-half the annual fall of rain on this area) 951,567,831 cubic feet, from which was deducted evaporation and leakage at one-fifth, 190,313,550 cubic feet, leaving 761,254,281 cubic feet, to which was added natural flow of streams, making the total available supply 955,576,521 cubic feet. The quantity of water required for the canal was estimated by Mr. Trimble, for a trade of 125 lockages and 270 days navigable season, at 1,196,774,946 cubic feet, or 3077 cubic feet per minute. For the size of canal adopted by Mr. Trimble, this is but about one-quarter the quantity required at the lowest possible estimate. The size of canal was fixed at 32 feet wide on bottom, 60 feet at surface, and six feet deep. This route was pronounced impracticable by Mr. Trimble. Digitized by Google 99 SENECA ROUTE. The cost of canal on this route was stated by Mr. Trimble at $6,324,300. This route, leaving Baltimore, follows the valley of Patapsco to Elk Ridge Landing; thence ascends the valleys of Deep and Licking's runs to Merrill Ridge; thence acrosss the ridge and down Chandler's Branch to the north branch of Patuxent; thence crosses the tongue of intervening land at a depression near a school house, and reaches the "Big Patuxent;" thence ascends the same to Etchison's mill; thence, crossing the summit, descends the Seneca to the Potomac. Four lines, says Mr. Trimble, were traced across the summit within a space of four miles. Here, Mr. Trimble observes, surveys were never before made over this summit. The summit alluded to is a spur of Parr's Ridge, diverging at Damascus in a southeast direction, and dividing the waters of the Patuxent on the east from those of the Seneca on the west. The elevation of the summit, one mile north of H. Griffith's, was found 587.83 feet above mean tide, and 122 feet above the Patuxent at Etchison's mill. A tunnel 690 yards long at this point was pro- posed, with a depth at extremities of same of 50 feet, to reduce the summit level to 495 feet above tide. This was assumed as the summit level, and the Patuxent was crossed 1½ miles above, near Annapolis Rocks, at an elevation of 36 feet above. He proposed to obtain the quantity of water required beyond natural flow, from reservoirs on Patuxent, Cabin Branch, head of of Hawling's River, and branches of the Seneca, together with the natural flow from the valleys. He estimated the drainage area of these basins at 16,640 acres, and the available supply 1,346,834,493 cubic feet. All of which is respectfully submitted. S. H. SWEET, Civil Engineer.
