Public Library Coo 9713 Digitized by Google CHIEF ENGINEER'S REPORT. ALBANY, February 11th, 1853. To W. E. Bleecker, Lansing Pruyn, John N. Wilder, G. C. Davidson, B. C. Brainard, Theodore Townsend, Visscher Ten Eyck, Orlando Meads and J. D. Was- son, Esq'rs, and others, a committee appointed by the city of Albany to inquire into the expediency of constructing a ship canal from Albany to New- Baltimore. GENTLEMEN: I regret that my preoccupation with public duties has prevented me from devoting as much time to the examination of the ques- tion of the proposed ship canal as the importance of the project merits. This duty has, however, been performed in a very thorough manner, by Messrs. Octave Blanc and Isaac D. Coleman, and a particular branch of it by Mr. Wm. A. Perkins. The reports of these gentlemen, and the maps of the proposed route of the canal, are herewith submitted. The object proposed to be accomplished by the work in question, is to afford an uninterrupted navigation to the city of Albany for such classes of vessels as are required to navigate the ocean, and thus permit the transfer of freight received by the canal to be made at Albany instead of New-York. The crowded state of the wharves in New-York increases the cost of transhipment at that place. The improvement in ques- tion would relieve that port of a portion of its business, and reduce the charges on that portion of the trade of the canals destined for Digitized by Google 4 exportation, as well as that which is received by importation from foreign and domestic ports. The plans which have been suggested for the accomplishment of these objects, are : 1. An improvement of the channel of the Hudson river. 2. An extension of the Erie canal to a point on the river where the navigation for ships is now interrupted. And 3. The construction of a ship canal which will connect the Erie canal with the Hudson at a point where it has an unin- terrupted navigation. The trade and commerce which are already concentrated at this city, are seriously taxed by the obstructions which they en- counter in the first twelve miles of the Hudson below this city. The improvement of the channel of the river has been a favorite plan with a majority of those who have examined this subject. The careful examinations of the river, which have been made by the engineers of the United States government, have induced them to adopt a plan for its improvement, which has been com- menced, and so far extended as to show its effect. These plans, however, contemplate securing a depth of but nine feet of water, which would not be sufficient for the purposes you design to accomplish. The cost of obtaining a depth of water in the Hudson which would admit the heaviest class of vessels to your wharves, is, without closer examination, evidently too great to warrant its ex- penditure, even if there were a reasonable hope that a plan could be devised by which such a depth could be permanently main- tained. The second plan would require the breaking up of all of the existing arrangements of business at Albany and Troy, which would cause a sacrifice of property vastly greater than the expen- diture which is required to carry out the third plan. The last is the particular subject which you have desired to be examined. Having carefully investigated the matter, 1 was led to recom- mend to your committee that the surveys and estimates should be based on the plan of an independent canal, elevated above the level of the river, so as to be entirely free from the expense of per- forming any of the excavations below the level of the water in the river, and with its works protected against the influences of the Digitized by Google 5 freshets which have so frequently proved destructive to property in this city. This suggestion having met with your approval, Mr. Blanc was instructed to make his surveys and estimates on that plan. The only objection of much force to this plan arose from the apprehended difficulty or expense of procuring sufficient water to supply the canal upon the elevated level proposed. I suggested two plans for this purpose. The first was to raise the water by steam power from the river ; and the second to obtain it by regulating the discharge of the waters of the Norman's Kill by constructing retentive reservoirs thereon. The expense of both of these methods has been examined; the first by Mr. Coleman, assuming certain estimates which were pre- pared by me in reference to the Brooklyn Water Works; and the second by Mr. Perkins. I have not had sufficient leisure to examine the details of either of these estimates, but have so far reviewed them as to be satisfied that both plans are practicable, and that the estimates of cost can be relied upon. The dimensions of the canal, upon which the estimates are based, are as follows The width at bottom, 50 feet ; at surface water, not less than 120 feet ; and 20 feet depth of water. The Locks at New Baltimore are to be of sufficient size to pass vessels 300 feet long and 50 feet wide, provided with extra gates, so as to use less length of lock when vessels of smaller size are passed. The Locks at Albany, connecting the proposed basin with the river, are to be of sufficient size to pass boats 215 feet long and 30 feet wide, and are also to be provided with extra gates. The length of the canal is twelve miles; of which, three miles can be made with a surface width of water of 300 feet, with but little extra expense. Another three miles can be made of the same width, at an estimated extra expense of $50,000. These dimensions are believed to be amply sufficient to accom- modate the classes of vessels for which they are designed. In connection with this project, provision has been made in the plans and estimates for a large basin, covering 255 acres of land, and nearly one mile in length. The particular description of the several works proposed will be found in the annexed report. Digitized by Google 6 The estimated cost of the canal, basin, locks and works complete, according to this report, is $2,450,000. I have examined the prices contained in these estimates, and believe that they are sufficient. In works of this character, unex- pected difficulties occur which enhance the cost. For this reason I should deem it safe to assume that the cost would amount to three millions of dollars. The annual expense of furnishing a supply of water, tending the locks, and keeping the canal in repair, is stated at $75,000 per annum. I deem this sum sufficient, and, when added to the interest on the estimated cost, it will amount to $285,000 per annum. The value of the lots on the basin and piers, as stated in the report, has been taken at the prices estimated by some members of your committee. I have not sufficient information in regard to the probable value of such property to form an opinion of the correct- ness of this estimate. It gives a value of $1,600,000 to these lots, the annual interest of which is $112,000. If this sum should be realized, it would be equivalent to reducing the annual expenditure to $173,000, which sum must be reimbursed from the tolls on the tonnage passing through the canal. The average toll charged on the State canals is about 21% mills per 1000 pounds per mile. In the report, the toll on the ship canal is assumed at about 4 mills, or ten cents per ton for the length of the canal. There is but little doubt that ten cents would be a reasonable charge for the advantages which the work in question would furnish to the commerce using the same. This rate of toll would require 1,730,000 tons to reimburse the balance of the expenses of the interest on the cost, and the annual main- tenance, after deducting the estimated receipts from the wharf lots on the basin. Whenever 2,850,000 tons annually pass through the canal, paying the toll above stated, it will yield a sufficient revenue to pay the interest and maintenance, and leave the rents of the basin lots as profit to the proprietors of the canal. It is assumed in the report that the tonnage of the canals, ar- riving at and departing from tide water, will amount to four mil- lions of tons by 1856, and to six millions by 1860, and that one- half of this tonnage may be expected to pass through the canal. I am of the opinion that the tonnage which will pass through the canal after its completion, and the rents of the basin lots, will Digitized by Google 7 be sufficient to reimburse the interest on the cost of construction and the annual expense of maintenance. The future increase of business will be a guarantee for a fair profit on the investment. The examination which I have given to the subject enables me to say, with confidence, that the work presents no serious diffi- culty in its construction. The estimates, as corrected, I believe to be ample to meet the expense of building it. I am not sufficiently acquainted with the subject to be able to state, with the same de- gree of confidence, that the estimates for the revenue are correct, though I am quite sure that they are not overrated. The practi- cal knowledge possessed by your committee will enable you to correct any errors in this estimate. Very respectfully, your ob't serv't, WM. J. McALPINE. Digitized by Google Digitized by Google WM. J. MCALPINE, Esq. Sir-The undersigned herewith submit, for your consideration, the enclosed report, prepared under your direction, containing descriptions and estimates of the plans for a proposed ship canal, to overcome the obstructions in the Hudson river below Albany, together with some remarks upon the same. Respectfully yours, OCTAVE BLANC, 1. D. COLEMAN, Civil Engineers. 2, Digitized by Google Coogle RESIDENT ENGINEERS' REPORT. IT being conceded that an uninterrupted channel for ship navi- gation already exists from the mouth of the Hudson river to a place called Four Mile Point; about four miles north of the city of Hudson, the examinations of the river have been confined to that portion between the city of Albany and Four Mile Point. It is believed that sufficient examinations have been made to develop all the essential features and difficulties to be overcome. By reference to the soundings upon the map, it will be seen that from the village of New-Baltimore to Four Mile Point, there is, at extreme low water, a channel from 15 to 30 feet deep; which channel is, at its shallowest points at high tide, generally 20 feet ; a few points may not exceed 18 feet, at the lowest stage of the river in the dry season. It is safe to assume that there will be at low tide a channel of 15 feet, and at high tide of 18 feet depth, during the whole season, and for most of the time from 2 to 5 feet additional depth of channel. From the city of Albany to the village of New-Baltimore, the channel is very uneven, and at several points does not exceed 7 or 8 feet depth of water ; and that depth is frequently diminished by the formation of bars during spring floods. The deeper chan- nel is at many points both narrow and crooked, and frequently changing its location by the moving of the sand in the bed of the river, rendering it no uncommon occurence for boats drawing not more than 5 or 6 feet of water, though managed by experienced and skilful pilots, to be run upon the ground. From the register of the New-York Custom House, it appears that of the vessels trading at the port of New-York, about 7/80 of them do not exceed 12 feet draft of water, and of the remaining 1, most of them draw from 12 to 18 or 20 feet. A very small number draw over 20 feet. Digitized by Google 12 Your attention is called to statements annexed, marked A and B, exhibiting the dimensions, tonnage, and draft of water, of a portion of the vessels trading at the city of New-York ; also of statement marked C, exhibiting the character of boats trading at the city of Albany. From information obtained of gentlemen long engaged in freight- ing upon the river, it appears that the average cost, upon the following items of expenditure, for a trip from Albany to New- York and return, is as follows CANAL BOAT OF 90 TONS. # Towing of boat, $38 00 t8 days at daily expense of hands, of $4.00, 32 00 Charter of boat ($400 per an.) and repairs, equal, 20 00 $90 00 BARGE OF 200 TONS. # Towing of barge, $62 00 t 9 days at daily expense of hands, of $4.00, 36 00 Charter of barge ($600 per annum) and repairs, 30 00 $128 00 That, if the depth of water allowed the passage of vessels of 1000 tons, the cost of the above items of expenditure would be, for a BARGE OF 500 TONS. Towing of barge, $100 00 10 days at daily expense of hands, of $4.00 40 00 Charter of barge ($1,250 per annum) and repairs, 60 00 $200 00 VESSEL OF 1000 TONS. # Towing of vessel $115 00 12 days at daily expense of hands, of $4.00 48 00 Charter of vessel ($2,000 per annum) and repairs, 87 00 $250 00 * Gentlemen engaged in the business represent that, owing to the difference of shape of canal boats and barges, as compared with sea-going vessels, it costs consid- erable more per ton to tow the former than the latter. t The number of hands employed upon canal boats is generally 4, while on barges there are but 2; but as they assist in loading and unloading, and to avoid any dis- proportion which shall, in the comparison, be prejudicial to the small boats, the same number of hands has been estimated for a barge as a canal boat. Digitized by Google 13 Assuming that the trade upon the river will average 3 tons down freight to 1. ton up freight (the New York State canals average nearly 4 tons down freight to 1 ton up freight), and the foregoing items of expenditure will compare as follows: PER CANAL BOAT OF 90 TONS. 90 tons down freight, 30 tons up freight. 120 tons for $90, or 75 cents per ton. PER BARGE OF 200 TONS. 200 tons down freight, 66% tons up freight, 266g tons for $128, or 48 cents per ton. PER BARGE OF 500 TONS. 500 tons down freight, 166 tons up freight, 666² tons for $200, or 30 cents per ton. PER VESSEL OF 1000 TONS. 1000 tons down freight, 3331 tons up freight, 13333 tons for $250, or 18ᵃ, cents per ton. The other expenditures incidental to freighting, when not equal, will be less per ton on a large cargo than a small one. There not being the necessary depth of water in the river to accommodate such vessels as are generally employed in the coast- ing trade of the United States, between the city of New-York and the British Provinces, West India Islands, &c., but a very small proportion of boats that are used on the river go beyond the city of New-York; and the trade between Albany and Boston, Provi- dence, Baltimore, &c., &c., is generally subject to a transhipment at New-York. The expense of transhipment, under the most favorable circumstances, is 2 cents per barrel of flour, or 20 cents per ton ; and where flour goes into store at New-York and then is reshipped, it is subject to the following charge Digitized by Google 14 Landing from boat, 1 cent. Cartage, 3 to 4 cents. Cooperage, 2½ cents. Shipping, 3 cents. 91/2 to 10½ cts., say 10 cents per barrel, or $1.00 per ton. The extra charges upon flour are less than upon the average of other goods. Another advantage would arise from having ship navigation extended to Albany; most of property is damaged or wasted more or less every time it is transhipped. The damage to flour by sifting out of barrels not perfectly tight, and waste by packages being broken open, is represented by dealers as equal on an average to 1 per cent for each transhipment (some dealers say 2 per cent), or an average of 5 cents per barrel. Wheat and other grains, moved in bulk, are subject to considerable loss by each tranship- ment, and most of goods are damaged in that way. Every tran- shipment of property is therefore a tax upon it, not only for the labor that is required to perform the operation, but also in diminish- ing the value of the goods. The extension of ship navigation, as proposed, would remove the necessity of one transhipment now required on a large pro- portion of property now shipped from Albany. Comment on the foregoing is unnecessary; the whole is resolved into one question : Is the trade upon the Hudson river of sufficient magnitude to justify the necessary expenditure to make the desired improvement? There are no means of knowing the amount of trade now done upon the Hudson river, at and passing the city of Albany. That it is greater than the arrivals and departures to and from tide water, by the Erie and Champlain canals, is generally conceded by the business men of Albany. But a wide difference of opinion exists, as to the per cent. of advance of trade, over that on the canals, ranging from 10 to 25 per cent. It would appear safe to assume, for the purposes of this exami- nation, that the trade on the Hudson river at Albany is at least equal to the arrival and departure to and from tide water by the Erie and Champlain canals.

When we reflect from whence the majority of this great trade flows -that it is from what is as yet comparatively a new country, with every probability that, for a long time to come, it will continue to increase in population, wealth and trade, equal to its present growth-we may reasonably anticipate that, unless the trade is diverted into some other channel, the rate of increase upon the New-York State canals, and the Hudson river, will be equal for the next ten years to what it has been for the last ten. When we turn our attention to the geography of the country, examine the vast chain of mountains that divides the west from the east, the Mississippi from the Atlantic, we find no other routes that contain the natural advantages, and the facilities of rendering those advantages available, equal to those that lead through the valley of the Hudson. A proper spirit of enterprise, in well di- rected improvements, cannot fail to command the trade of that vast extent of country. The citizens of the western states, well aware of this natural advantage, prompted by a proper regard for their own interest, and having full confidence in the determined spirit of New-York Digitized by Google 16 to reap the rich harvest, project their lines of internal improvements with a view of reaching the sea-board by way of the State of New- York. This is also the natural channel for the trade of Canada West. When we take into consideration these facts, astounding as the figures may at first appear, there is much reason to anticipate that, with proper facilities to accommodate the growing commerce, the rate of increase in the trade that will seek the Hudson river for the next 10 years will rather increase than diminish, as com- pared with former years. Allowing the same rate of increase to continue, that has been realized for the past 10 years, the trade of 1856 will reach an ag- gregate of more than 4,000,000 tons, and in 1860 of more than 6,000,000. Without claiming that these figures give the present and proba- ble future trade upon the river with the accuracy that is desirable, they are a sufficient approximation to give us a general idea of the magnitude of that trade. If the river afforded a channel for the navigation of vessels drawing 12 feet of water, the propriety of making any large ex- penditure of money to deepen the channel might well be doubted ; or, if such channel could be obtained by a reasonable outlay, it might be questionable whether it would not be better to submit, with such facilities as that would afford, rather than to make an enormous expenditure to obtain deeper water. This consideration leads us to inquire into the practicability of obtaining a channel of 12 feet of water from the city of Albany to New-Baltimore. This is best answered by an examination of the various investigations, the proposed improvements, the work which has been done, and the results, of which a very full history, up to the year 1843, is given in the report of Capt. George W. Hughes, an extract from which is appended, marked. Also, extracts from the report of a special Board of Engineers, having the matter in charge, are ap- pended, marked. From these reports, it appears that a large amount has been ex- pended in attempts to improve the navigation of the river ; that the subject has engaged the attention of some of the ablest engi- neers of the country and no doubts can be entertained that the money, as a whole, has been as judiciously expended as could reasonably have been expected, considering the many difficulties surrounding the case. Digitized by Google 17 As Congress has uniformly included the river between Troy and Albany with that between Albany and New-Baltimore, and in all probability will continue to do so in all future appropriations for its improvement, it will be necessary to estimate from Troy to New-Baltimore, whenever we look to Congress for the means of such improvement. Captain Hughes, in his report, dated Novem- ber 30th, 1843, estimates that " to make a free, easy and unob- structed navigation, between Troy and the city of New York, it will require $449,634 10 to which he adds the following : " To this, of course, must be added whatever may be necessary to re- pair the works that have sustained injury, and to replace the machinery that has deteriorated in consequence of the long sus- pension of the appropriations." This would probably make the amount $500,000 at the time of his report. Since that time, many points have been seriously in- jured, and new obstructions formed in the river, which cannot fail to add at least 20 per cent to his estimate. Estimate, say $500,000 20 per cent, 100,000 $600,000 This does not include the expenses of engineering, or the su- perintendence of the work while in progress. In this it is assumed that the calculations made by the engi- neers were all correct, and their plans perfect; but by reference to sections 66, 67 and 68 of the report of the special Board of Engi- neers, it will be seen that there were no accurate examinations made with reference to the kind of improvement suggested, and the estimates were based upon the principle that " it is necessary, however, to make suppositions of some sort, as to all these matters, in order to obtain our estimates." The estimate of the special Board of Engineers was $819,634,10 (Captain Hughes adopts their estimate as the basis of his calcula- tions), but before one-half of the work was completed, the Federal Government refused the necessary appropriations to continue the improvement; and while it is admitted that much benefit has been derived from the work already constructed, and that it is impossible to determine what would be the exact result if the plan should ever be carried out, a careful examination of the effects 3 Digitized by Google 18 of the work already completed gives much reason to fear that it would fall short of affording the proposed depth of water. River improvements have always proved among the most diffi- cult duties that the engineer is called upon to perform. Subject to various and complicated circumstances, few if any plans of im- provement have equalled the expectations of their projectors. The improvement of the river Clyde, in Scotland, is regarded as among the most successful; but that has been the subject of 200 years' experiment, and vast expenditure of means employed. If the works upon the Hudson, so far as completed, have not fully answered the expectations of their projectors, they have but shared the fate of nearly, or quite all river improvements; and only adds another link to the great chain of evidence that the improvement of the bed of a river is attended with great expense and uncertainty of results. The spring floods of 1852 created such obstructions, at Cuyler's bar and at Castleton, that, persons interested in the navigation of the river, raised by subscription $3,000, and the Legislature of this State made an appropriation of $10,000 for the purpose of removing the most serious of the difficulties and but for such expenditure, navigation, by a large class of boats engaged in the river trade, would have been suspended between the city of Albany and Cas- tleton, the consequences of which cannot well be estimated. The Federal Government having extended its jurisdiction over the Hudson river, and expended a large amount on improvements, the idea cannot be entertained for a moment that any extensive improvements will be made, except by virtue of appropriations made by Congress, sanctioned by the President. To speculate upon the chances there are in favor of appropria- tions to finish the projected improvements, it is apprehended is no part of an engineer's duty. Suffice it to say, that the present Con- gress, at its last session, made an appropriation for that purpose of $50,000. This is, however, no positive index by which we can judge of the future action of that body, even at its present session, much less when a new Congress assembles, containing a large number of new members. But assuming that the necessary appropriations should be made, and that the improvements should answer the hopes of the projec- tors, will that furnish the depth of water necessary to accommodate the trade which it is now sought to bring to Albany ? Digitized by Google 19 It will be seen that it is desirable to have a depth of water that will allow the passage of vessels drawing from 15 to 20 feet, and that a very large proportion will require 12 feet depth of water. The plans of improvement commenced contemplate a channel of 9 feet, and no estimate appears to have been made for a greater depth; indeed any improvement, beyond that depth, appears to have been regarded as impracticable. It will be apparent to every reflecting mind, without going through the forms of a mathematical calculation, that, as the depth increases, the cost will increase with greatly augmented proportions; and, from the estimates made for a 9 feet channel, it is evident that for 12 feet would require an expenditure far beyond the hopes of the most sanguine. We are, therefore, brought to the conclusion that, to afford ship navigation to the city of Albany, other plans than working in the bed of the river must be resorted to. Before closing this point of the investigation it is proper to remark that, by an examination of the soundings of the river, as taken at this time, with the general rules laid down by the special Board of Engineers for the improvement of the river, it will be seen that it would require a large addition, in extent of structures, to the amount estimated in their report. The origin of the project of a Ship Canal, parallel to the Hud- son river on the east side, from opposite Albany to the deep water between Coeymans and New-Baltimore, is due to the late Ed- mund Charles Genet; and though he was able to set the matter in so clear a light as to command the respect of some of the first men of the State, he never enlisted sufficient influence to execute his designs. To use his own words : "The idea of a Ship Canal has, I know, been received with diffidence and reserve by several Commissioners, who did not, at the first glance, see into the prac- ticability and utility of a measure of that magnitude." The proposition of Mr. Genet was for a canal upon the east side of the river. This, to accommodate Albany, would impose the necessity of keeping a channel open across the river, and the opening of channels along the city ; and, in addition to all the obstructions to be overcome at the time Mr. Genet urged his project, the Hudson River Railroad now occupies a large portion of the line upon which he proposed to run, and is a serious objec- tion against locating a canal upon that side of the river-so much, that it has not been thought proper to make any estimate, at this time, of the cost of a canal upon that side, Digitized by Google 20 The present examinations and estimates will, therefore, be con- fined to the west side of the river. At the time Mr. Genet urged his project, various plans for constructing the canal were proposed 1st, a canal 16 f't deep at low wat'r, and 109 1ᵃ f't wide at top wat'r. 2d, " 7 " " 109 " " 3d, " 10 " " 109 " " 4th, " 10 " " 200 " " 5th, " 10 " " 300 " " All these projects propose that the canal should be excavated so that the surface of water in the canal would be the same as that in the river, the canal having a free communication with the river at each end of the canal ; in fact, either of them would have been but the opening of a new channel for the river. Among the most formidable objections to the plan were, that the canal would be liable to be filled up by the action of the spring freshets, which would overflow the banks; that it would be sub- ject to all the objections urged against an attempt to improve the channel in the present bed of the river; that it would be an end- less expense to keep the bottom dredged out. To obviate these objections, which it must be confessed are se- rious obstacles to the practical working of a canal built upon that plan, it is proposed that the canal should be elevated above the surface of the river, so that the top water line and the banks of the canal will at all times be above high water in the river; the outer bank, or side towards the river, to be so constructed that the action of the floods will not injure the canal. A careful ex- amination has been made of a line to locate a ship canal upon the west side of the river, with a view of elevating it so as not to be affected by the rise of the water in the river. No serious obstacles appear to be in the way of constructing such canal, and that part of Westerlo Island between the city of Albany and Normanskill affords a desirable location and facility for a capacious basin in connection with such canal. In addition to the security that such elevation would give to the permanence and utility of the canal, the banks of the canal and basin would afford a good location for the erection of large manu- facturing establishments which require large amounts of raw materials, and make it very desirable to locate at places that can be easily reached by water navigation, and thereby save the ex- Digitized by Google 21 pense of cartage. The heavy rise of water in the river at Albany, which during the spring floods sometimes reaches 18 feet, is a serious objection to locating upon the banks of the river. The ship canal and basin would afford locations which would have all the advantages of water communication that can be ob- tained on the banks of the river, without being subject to their in- conveniences. An estimate has been made of the cost of a ship canal and basin on the west side of the river from Albany to New-Baltimore the bottom to be on a level with the surface of low water in the river, and to have a depth of 20 feet water. (For location, see map annexed.) To construct the proposed basin will require the appropriation of about 255 acres of land, most of which is upon Westerlo Island, and will afford dockage and building ground of 1000 feet long and 200 feet wide upon the north end ; 5000 feet long and 200 feet wide on the east side, and next to the river; 1000 feet long and 200 feet wide on the south end ; and 6000 feet long, and of various widths, on the west side. Also, piers equal to 10,000 feet in length and 120 feet wide. In the present estimated cost is included the dock and embank- ment on the north end; 1000 feet of dock and embankment on each, the east and west sides; and 2000 feet of pier, with docks on each side ; the remainder of the east and west sides, and the south end, embankment and puddle wall, the same as for the canal. The whole upon the river side to have a heavy protection wall to guard against the floods, &c. The basin at the north end will communicate with the river by 2 locks combined, each 10 feet lift, capable of passing boats 215 feet long, 30 feet wide, (but very few if any boats that now trade at Albany, except steamboats, exceed those dimensions), with extra gates, so that boats of 100* feet in length can be passed without using unnecessary length of lock. # "The size of the most approved form of boat for freight for the enlarged canal, when drawing 6 feet of water and made to conform to the lock chamber, may be 95 feet in length, allowing 10 inches for play between the lock gates when three- fourths open ; 15 feet 6 inches in width upon its bottom, and 17 feet 6 inches at top water line, allowing 3 inches space upon each side of the boat between it and the lock walls."-Report of the Canal Commissioners in relation to the length and width of the chamber of the enlarged Eric canal locks, &c., in Senate, March 2d, 1849. Doc No. 50, P. 12 Digitized by Google 22 From the south end of the basin the canal will extend to New-Baltimore, a distance of 12 miles ; it will be 50 feet wide on bottom, and 120 feet wide at top water ; the inside bank to be lined with stone-work, and the outside, whenever exposed to the action of the river, to be protected by a heavy stone wall ; the embankment to be carried 5 feet above water line, 20 feet wide on top the outside slopes to be 2 horizontal to 1 vertical ; the inside slopes from the bottom to 14 feet high, 11 horizontal to 1 vertical, and at 14 feet high to have a set off of 61 feet ; from thence to the top a slope 1+ horizontal to 1 vertical ; the embankment to have a puddle wall carried 1 foot above top water line, 3 feet wide at the top, with a batter increasing its width of 1 foot horizontal to 3 vertical, and to be carried 3 feet below the natural surface of the ground, or deeper, whenever the material is of a character to require it. At New-Baltimore there will be 2 locks combined, each ten feet lift, capable of passing vessels 300 feet long, 50 feet wide, with a depth of 20 feet of water, with extra gates, so that in passing boats of 100 and 140 feet no more length of lock will be used than is necessary ; these locks will require a protection on the river side, and docking to pass down below them for the accom- modation of boats in tows. Three streams of considerable size will be taken into the canal from the west side, and will require waste-weirs opposite, or nearly so, constructed in a manner that, during the suspension of naviga- tion, the water may be passed directly into the river, and, during floods, pass the surplus water. The waste-weir at the Normanskill should have a foundation of bearing piles, concrete and timber ; the abutment and piers of rock-dressed masonry. It will require a water-way of 80 feet, divided, by 3 piers, into 4. spaces of 20 feet each. One of the spaces should have a timber bulk-head, with cast iron valve gates, similar to those used on locks. The other 3 should have solid timber bulk-heads so constructed as to be easily removed during the suspension of navigation. The waste-weir at Coeymans will have a rock foundation, and the one at New-Baltimore, by locating a short distance either side of the stream, can be built upon rock ; but the masonry and other work will have to be carried down 3 feet below the bottom of canal. These will be built substantially, the same as the one at Digitized by Google 23 Normanskill, except the water-way will be 40 feet, divided in 2 spaces, 1 with valve gates and the other solid timber bulk-head, constructed so as to be easily removed. Six culverts, or pipes, will be required, to pass drainage waters from the west side of the canal to the river. Cast iron pipes, 30 inches in diameter, with suitable protection walls, have been esti- mated for that purpose. Two swing bridges, one at the basin and one at Coeymans, will be required.

The amount of water requir- ed will depend upon the loss by evaporation from the surface, filtration through the bottom and sides, waste at the waste-weirs and locks, and the number of lockages per day. The loss by evaporation will be in proportion to the area of the surface of water exposed, and in the dry season of the year ranges from 1/6 to 1/8 of an inch per day, average say 1/6 of an inch. The canal will be 12 miles in length, to which should be added the locks at New-Baltimore and some portions of extra width, which will make the whole equal 121 miles of 120 feet wide. 7,920,000 square feet.

The filtration through the sides and bottom cannot be deter- mined with any degree of certainty. Experiments upon works already built are the only data upon which to base calculations. This must necessarily be imperfect, as the loss, through different materials, though of the same dimensions and subject to the same pressure of water, will not be the same. The following may be regarded as the most reliable experi- ment :- " In July last measures were taken to ascertain the quantity of water consumed by the present canal between Wayneport and Pit-Lock, a distance of 36 100 miles. Guages were made by obser- ving the velocity with which the water moved in a prism of known dimensions, embracing a section of the canal 200 feet in length, at points the most favorable for uniformity of flow that could be selected. These were at Wayneport, 4 miles west of the west lock at Macedon on the Palmyra level, about 31 miles east of the east lock at Macedon ; and on the Clyde level, a short dis- tance above Pit-lock. From a mean of three observations each day for a term of 33 days, taken at all the above mentioned places from the 30th of July to the 31st of August inclusive, the results shown in the following table were obtained Distance in Quantity passing Loss per minute Loss per mile per Average loes per miles. per minute. from place to fninute from place mile per minute place. to place. on whole distance.

There are several short distances, upon that portion of the canal between Wayneport and the point of observation on the Palmyra level, that are known to be open and leaky; and the ratio of loss, as compared with the other sections taken, is still further increased by the quantity that escapes at the wood trunk over Mud Creek. It should also be remarked that the summer was unusually dry, and the supply less for the time in which the observations were taken than during any other portion of the season."-Canal Com- 4 Digitized by Google 26 missioners' Report, made January 12th, 1848.

Embankment built with a puddle wall, as proposed, will reduce the filtration through the artificial banks of the canal to less than an average, as compared with the canals of this State. The natural banks and bottom will be of a very compact mate- rial-much of it clay. The general appearance on each side of the river is the same. Mr. Genet, in treating of the project of a canal on the east side of the river, says: " The filtration of the water of the river through the soil was considered another impediment. I have myself voluntarily impo- sed these preconceptions of my mind, and approached my plan with the severity of a judge; but the surveys, borings and geological observations have incontestibly proved that a uniform depth of 21 feet may be excavated on the line of the projected ca- nal without a single obstacle; that no filtration from the river seems to penetrate the alluvial bed." If, upon excavating the canal, any points should be found of open material, they should be lined with puddling. We might then reasonably conclude that the loss by filtration would be reduced to as small proportion as any part of the Erie canal of the same length, and that it will be perfectly safe to assume as data the experiment of 36₁₀₀ miles, a portion of which is known to be of open material, and subject to additional loss at the wood trunk over Mud Creek. For the purposes of this estimate, 50 cubic feet per mile per minute will be used as the loss by filtration upon the Erie canal, assuming the bottom and sides to be as compact as it is proposed to render them upon the ship canal. b In all cases where the banks are the same, and the facilities for the escape of the drainage at the bottom are equal, the loss by fil- tration on bottom will be in proportion to the square of the depth multiplied by the width of the bottom, and, on sides, the square of 1 of the depth multiplied by the length of slopes. But as the width of the embankment is increased, the facilities for the escape Digitized by Google 27 of drainage are diminished ; so also as the width of bottom is in- creased, the proportion of drainage from the bottom is lessened, for the filtration through the bottom must depend upon a horizontal as well as vertical movement for its escape ; it is evident that the water that drains from the outside or edges of the hottom, verti- cally, will impede the horrizontal escape from the centre. In the calculations for the canal, no deductions will be made for the above considerations ; but for the basin, the filtration through the bottom will be estimated for only 100 feet wide; the sides of the basin will be estimated as the same length of sides of the canal. Estimate for length of canal, 12 miles. " " embankment for basin equal to ca- nal, 1.6 " " " bottom for basin equal to canal, 2.25 " " total sides 13.6 miles; for total bottom 14.25 " / The Erie canal (old) is 24 feet wide on bottom, 4 feet depth of water, and the side slopes 8.944 feet in length, each. The proposed ship canal, 50 feet wide on bottom, 20 feet depth of water, and the sides (which will have irregular slopes) will equal a slope of 40.311 feet in length, each. The proportion of filtration through the bottom would be as : Erie Canal. Ship Canal. (4 x 24) : 1:: (20 X 50) : or ( 2 X 24) : 1:: (4.472 X 50) : 4.66 The proportion of filtration through the sides would be as : Erie Canal. Ship Canal.

If the resistance to filtration is the same on the bottom and sides, the proportion is : Bottom. Sides. V4 X 24 : 2 X 8.944 X 2 : .527 Or in proportion of 100 loss on bottom, to 52.7 loss on sides.

The filtration through sides for 1 mile of Erie canal would be, 17,25 " " The filtration through total for 1 mile of Erie canal would be, 50.00 " " This would give for proposed ship canal as follows : For bottom 32.75 X 4.66 = 152.62 cubic feet per mile per minute.

X 4.66 = 116.50 cubic feet per mile per minute. For sides 25 X 10.08 = 252.00 " " " For bottom 116.50 X 14.25 = 1660 c. ft. for canal and basin per min. For sides 252.00 X 13.60 = 3427 " " " Total, 5087 " " " For the purposes of this estimate the last amount will be as- sumed. At the waste-weirs there should be no leakage except at the gates ; the estimate is for cast iron gates, and if they are properly fitted the waste will not exceed 100 cubic feet per minute for each waste-weir. Loss of water at waste-weirs, 100 X 3 = 300 cubic feet per minute. The estimate cost of the locks contemplates the building of the gates and fixtures in such manner as not to admit of a large waste by leakage; and if so built and kept in proper repair, 1000 cubic feet per minute for each set of locks will be ample allowance. Loss of water by leakage at locks, 1000 X 2 = 2000 c. ft. per minute. The amount of water required for lockages will depend upon the trade done upon the canal. For a trade of 10,000 tons per Digitized by Google 29 day passing through each set of locks, it would require 100 lock- ages of an average of 100 tons each, and 50 lockages of an average of 200 tons each. The plan for the locks at the basin will admit of the passage of two canal boats or small barges at the same time ; and of barges, sloops, schooners, brigs and vessels 215 feet long, 30 feet wide, and drawing 8 feet of water. These locks would probably average 100 tons per lockage with the present class of boats that would seek the ship canal ; and when the enlargement of the Erie canal is com- pleted, that will pass boats of more than 200 tons, and it is pre- sumed that the majority of business done on that canal will be with the largest class of boats. Estimate that there will be 75 lockages requiring 115 ft. l'th of lock. " " " 15 " " 165 " " " " 10 " " 230 " then we have (115 X 30 ₫ X 10 X 75) + (165 X 30 ₫ X 10 X 15) + (230 X 30 X 10 X 10) = 24 X 60 2862 cubic feet per minute. The locks at New-Baltimore will pass three canal boats or small barges, or two large barges, sloops or schooners, at the same time ; and vessels which do not exceed 300 feet in length, 50 feet wide, and drawing less than 20 feet of water ; and, as barges and canal boats move in tows between Albany and New-York, it is presumed that the lockages at New-Baltimore would not average less than 200 tons ; and lockages which do not average more than that tonnage will not require an average of more than 170 feet length of lock. Then we have 170 X 511 X 10 X 50 24 X 60 = 3025 cubic feet per minute. Locks at basin will require 2862 cubic feet per minute. " New-Baltimore " 3025 " " Total lockage-water, 5887 This estimate of the amount of water required for a trade of 10,000 tons per day is for the present sized boats trading at Albany; but if the increased facilities attract a larger class of vessels, the same amount of lockage-water will accommodate a large increase of tonnage. So also the capacity of the locks, with the same amount of water, may be augmented by using those at Digitized by Google 30 the basin for boats not more than 100 feet long, and those at New- Baltimore for boats not more than 140 feet long, as four combined locks of 5 feet lift each. This would probably allow of an addi- tional tonnage of 50 per cent. with the above estimate of lockage- water. It has also been suggested that the superior advantage which this basin would afford, and the necessity which exists for a dry dock lock at Albany, would make it desirable to build one in connection with the basin; if so, 1000 cubic feet of water per minute should be allowed for that purpose. The foregoing estimates of the amount of water required for the canal and basin are upon the supposition that the embankments, waste-weirs and locks are all kept in good condition : to cover con- tingencies, 10 per cent. should be added to the whole amount.

To obtain this amount, two modes are suggested One, by ele- vating the water from the river by steam power ; the other, to build reservoirs on streams which will flow into the canal, and save, during floods and the suspension of navigation, a sufficient amount of water to use in the canal during navigation. If the first should be adopted, you would at all times have the benefit of the natural flow of the streams, which would for a por- Digitized by Google 31 tion of the time afford sufficient supply, and at other times a par- tial supply, besides the 2000 cubic feet above estimated, and it is not probable that the canal would draw its supply from the river on an average of more than six months each season. Therefore in estimating the cost of steam power, the quantity required will be assumed at 14,000 cubic feet per minute for a period of two months, 12,000 cubic feet per minute for a period of two months, and 5000 cubic feet per minute for the remaining two months. These quantities will be ample for the driest, and more than will be required in ordinary seasons. In the "report made to the water committee of the common council of the city of Brooklyn, April 15th, 1852, on supplying the city with water; by William J. McAlpine, civil engineer," a minute estimate is made of the cost of raising water by steam power, extracts from which are appended, marked. From these extracts it will be seen that " the duty of the engine has been calculated from the following data: The elevation of 5,000,000 gallons of water in 12 hours, through a pipe 6000 feet long, 30 inches in diameter, and to a height of 190 feet. "This duty, including the friction of the machinery, and of the water passing through the rising main, is equal to 17,000,000 of pounds raised one foot high per minute, or about 515 horse power. " An engine to perform this duty, must have a steam cylinder of 72 inches in diameter and 12 feet stroke, working steam at 20 pounds pressure per square inch. " Two plunge pumps are proposed to be driven by this engine; and, to make provision for the leakage after the valves become worn, they must be 3 feet diameter, and 81 feet stroke." # # "The engine has been calculated for a slow motion, low steam, and for working but 12 hours per day." " ESTIMATED COST OF ENGINES AND PUMPS. " Condensing engines, steam cylinder 72 inches diameter, 12 feet stroke, and boilers. $70,000 00 "Pumps and fixtures, 20,000 00 $90,000 00" It is proposed to elevate the ship canal, so that its surface of water will be 20 feet above the surface of the water in the river at extreme low tide; this will make it necessary to elevate the water on an average, say 18 feet. Digitized by Google 32 The maximum supply required is 14,000 cubic feet per minute, or equal to 28,000 cubic feet per minute, for 12 hours per day. 28,000 X 18 X 62.5 = 31,500,000 Add 20 per cent., = 6,300,000 = 37,800,000 pounds per minute to be raised one foot in height. This supply will be required for a period of two months. For another two months, it will require a supply of 12,000 cubic feet per minute, or equal to 24,000 cubic feet per minute, for 12 hours per day. 24,000 X 18 X 62.5 = 27,000,000 Add 20 per cent, = 5,400,000 = 32,400,000 pounds per minute to be raised one foot in height. For another two months, it will require a supply of 5000 cubic feet per minute, or equal to 10,000 cubic feet per minute, for 12 hours per day. 10,000 X 18 X 62.5 = 11,250,000 Add 20 per cent, = 2,250,000 = 13,500,000 pounds per minute to be raised one foot in height. From this comparison, it appears that to elevate the water by steam power will require two engines and pumps, equal in capacity to those estimated for the Brooklyn water works; the cost of which would be, $90,000 X 2 = $180,000. It further appears from the same report that the estimated cost of running such engines 12 hours per day, for one year, is as fol- lows: 15 tons of coal per day, $5, $75; equal per annum to, $27,375 00 2 enginemen per day, $2, $4; " " 1,460 00 2 firemen per day, $1,50, $3; " " 1,095 00 Oil, tallow, &c., per day $5, " " 1,825 00 Repairs of engine and machinery, 1,000 00 The age of the engine and machinery may be assumed equivalent to an annual cost of, 4,500 00 Total cost per annum, $37,255 00 Digitized by Google 33 The additional cost of the second engine of the same capacity would be as follows : 15 tons of coal per day, $5, $75, equal per annum to, $27,375 00 1 engineman " $2, $2, " " 730 00 Oil, tallow, &c., repairs of engine, and depreciation, 7,325 00 Total cost per annum, $35,430 00 Total for 2 engines per annum, $72,685 00 The two engines would raise 34,000,000 pounds one foot per minute. For the ship canal it would require that both engines should be kept at work four months, and the remaining two months would require but one engine. The cost of working the engines will be nearly in proportion to the amount of water elevated, which will give the cost of running the two engines four months, or one-third of a year, as follows For 2 months the quantity to be elevated will be equal to 37,800,000 pds. per min.

It was not deemed necessary to make a personal examination of the facilities of constructing reservoirs on the Normanskill, as Mr. Wm. A. Perkins, civil engineer, while engaged in making estimates of the cost of furnishing a supply of water to the city of Albany, made a full examination of the capacity of that stream for that purpose. He has very politely furnished an estimate of the cost of constructing the necessary reservoirs upon that stream. His communication is appended, marked. From his statement it appears that there is no question as to the 5 Digitized by Google 34 capacity of the Normanskill to furnish the necessary supply; the cost of which he estimates at $428,100.00. From this it will appear that the first cost of providing the sup- ply by reservoirs will be greater than by steam power, but the annual current expenses, after the work is completed, would be much less. Mr. Perkins estimates that it will require six reservoirs. These, if properly constructed, would not, including a person to attend each reservoir, exceed in annual current expenses each, $1000, or a total of $3,000, from which we make the following comparisons : Estimated cost of reservoirs, $428,100 00 Estimated cost of steam engines and pumps, 180,000 00 - Excess of cost of reservoirs, $248,100 00 Annual worth of $248,100.00, at 7 per cent., $17,367.00. Estimated annual current expenses by steam power, $30,000 00 Estimated annual current expenses by reservoirs, 6,000 00 Excess of annual current expenses by steam power, $24,000 00 Deduct annual interest on excess of cost of reservoir, 17,367 00 Making, $6,663 00 excess of annual cost of supply by steam power over the cost by reservoira. For the further purposes of this estimate, to provide for contin- gencies, it is deemed proper to use the estimated cost of the most expensive plan. LAND DAMAGES. Upon the question of land damages, the opinion of several gen- tlemen, whose judgment upon the matter is entitled to credit, has been consulted, and it is believed the sum of $200,000 is a liberal estimate for that item. ENGINEERING. In order to secure a proper construction of a work of the mag- nitude of the proposed ship canal, in addition to the final locating of the line, the perfecting of the working plans, laying out the work, and a general superintendence by competent engineers, it will be necessary that every portion of the work shall be performed under an immediate direction and inspection, by a constant attend- ance wherever work is in progress of construction. The engineering expenses are estimated at 5 per cent. Digitized by Google 35 ESTIMATE OF TOTAL COST. Section work, $1,109,870 00 Basin, 190,963 00 Culverts, 31,665 00 Locks at basin, 80,800 00 Locks at New-Baltimore, 256,420 00 Waste-weir at Normanskill, 22,715 00 Waste-weir at Coeymans, 9,852 00 Waste-weir above New-Baltimore, 12,160 00 Swing bridges, 20,000 00 Supply of water by steam power, 180,000 00 Land damages, 200,000 00 Engineering, 5 per cent., 105,722 00 Contingencies and miscellaneous, say 10 per cent., 220,168 00 $2,440,335 00 Say, $2,450,000 00 The present estimate has been for a canal 120 feet wide at top water ; six miles of the canal may be built, 300 feet wide at top water, without any increase of expense, except for the land taken and the increased waste of water by filtration through the bottom and evaporation from the surface, which would not amount to a large additional expenditure; another three miles may also be made 300 feet wide by an additional expenditure of about $50,000. The remaining three miles would mostly have rock cutting on the west side, and would not, therefore, require inside walls upon that side; it could be enlarged at any time when the wants of trade might require it, without incurring any additional expense more than would be necessary if the enlargement should take place at the time of original construction. The annual current expenses of such canal, after its completion and in use, are estimated as follows : Supply of water, if raised by steam power, $30,000 00 Lock-tending, 8 months, 4 men, at $40 per month, 1,280 00 " " " " $30 " 960 00 Watchmen, and ordinary repairs, 15 men, for eight months, at $30, 3,600 00 Materials and tools for ordinary repairs, 1,000 00 Watchmen, 6 men, 4 months, each at $30, 720 00 Mechanical work on repairs and materials, 2,000 00 Expenses for repairs and opening navigation in the Spring, 6,000 00 Superintendence and collection of tolls, 6,000 00 Carried forward, $51,560 00 Digitized by Google 36 Brought forward, $51,560 00 Miscellaneous, 1,000 00 Contingencies, say, 2,440 00 $55,000 00 An annual contribution to a fund to provide for the payment of expenses, caused by the extraordinary repairs to which a work of such mag- nitude is subject, say 20,000 00 $75,000 00 By the foregoing estimates it will be seen that to construct the ship canal and basin upon the proposed plan, will require the expenditure of $2,450,000.00: Which amount, at seven per cent., would be worth annually the sum of $175,500 00 Annual current expenses, estimated at 55,000 00 Annual contribution to fund for extraordinary repairs, 20,000 00 Making a total of $246,500 00 as the annual cost of such canal, or the amount which should be derived from such canal annually, to make the capital so invested paying stock. The sources of revenue will be the rents of docks, piers and other property connected with the basin, and the tolls on property transported on the canal. The present estimate for the basin includes the construction of docking and piers, and bringing into immediate use, in connection with such docks and piers, land suitable for building and forward- ing purposes, to the amount of 900,000 square feet, I of which is estimated as worth $1 00 per square foot $300,000 00 1 " " " 1 50 " 450,000 00 I " " " 2 00 " 600,000 00 Also, 200,000 square feet without docking, at $0 50, 100,000 00 Dry dock privileges, including use of water and 200,000 8. f. of land, 150,000 00 Total, $1,600,000 00 which, at 7 per cent., would be worth per annum, 112,000 00 The value of the above is estimated in accordance with the views of gentlemen acquainted with the value of property in the city of Albany. In addition to the foregoing, there are 2,500,000 square feet of the basin that could be converted into building and docking pur- poses at a profit, as soon as the wants of trade shall require more room than the docks and piers now estimated would afford. Digitized by Google 37 Amount which should be derived from the canal annually, $246,500 00 Estimated annual rents of basin property, 112,000 00 Which leaves the sum of $134,500 00 to be derived annually from the tolls on property transported on the canal. The present rates of toll upon the New-York State canals, is on all articles not enumerated or excepted, per 1000 pounds per mile, 4 mills. Special rates, less than the general rate, are established where articles if subjected to the general rate would not bear the expense of transportation, or would likely seek some other channel, or where the general interest of trade appears to demand such reduction ; while on the other hand, special rates, higher than the general rate; are charged upon some articles. The proposed ship canal and basin would be between 13 and 14 miles in length. A toll of 4 mills per mile per 1000 pounds would, for 13 miles, amount to 10Th cents per ton. It might be found good policy to adopt special rates of toll for different articles, but, as the amount of toll would be so small per ton, it would not probably be necessary to do so. It is proper to remark here that the present rates of toll on the New-York State canals are a great reduction from many of the former rates, especially for non-enumerated articles going from tide water, including merchandize in general, which was until the present season double the present rates. For the purposes of this estimate, 10 cents per ton will be as- sumed as the proper rate of toll upon all articles which should be transported upon the ship canal. This rate of toll will require an annual aggregate trade of 1,345,000 tons to pay the capital necessary to construct the canal and basin. We are therefore brought to the inquiry, whether it is reason- able to suppose that the canal can command that amount of trade. As has been stated, it costs for certain items of expenditure to move property on the Hudson river from Albany to New-York, or New-York to Albany, In canal boats of 90 tons, 75 cents per ton. In barges of 200 tons, 48 do do That it would cost in barges of 500 tons, 30 do do And in vessels of 1000 tons, 184 do do showing conclusively that it is much cheaper to move property in Digitized by Google 38 large than in small boats ; also, that property which is transhipped at New-York is subject in many cases to extra charges and loss in value. The interest of the forwarding merchant being promoted by the use of the canal, it is reasonable to suppose that it will command at least one-half of the trade upon the river. It has also been shown that the probable trade, which will seek the valley of the Hudson as its channel, will amount in 1856 to more than 4,000,000 tons, and in 1860 to more than 6,000,000. If these conclusions are correct, the business which will be done upon the canal will be of sufficient magnitude to make the ca- pital employed in its construction a profitable investment. It would be a work of supererogation to go into an argument to illustrate the benefits that accrue by an increase of commercial facilities ; the principle is well understood throughout the State. The constant efforts that are making in almost every county to better its commercial intercourse the numerous canals and rail- roads which have been constructed within the last few years, and the improvements that are made in the manner of conveying pas- sengers and freight, bear unmistakeable evidence that the general principle is well understood throughout the land that the con- struction of the proposed canal would cheapen transportation on the line of the Hudson river is beyond a doubt. The same law of trade which demands the reduction of tolls, and improvements which cheapen the cost of transportation upon the State canals, that the commercial circle accommodated by qur works of internal improvement may be extended and the amount of trade augmented, also demands the improvement of the facili- ties of trade between Albany and the seaboard. No fine-spun reasons need be urged to convince that any perma- nent reduction in the cost of transportation on the Erie canal, be- tween Albany and Buffalo, will increase the amount of trade be- tween those two places; the experience of past years has settled that question beyond a dispute; and practically it makes no differ- ence whether the reduction takes place between Albany and Buffalo, or Albany and New-York, the result will be the same. The citizens will be benefitted by the diminished cost of transpor- tation of property, the business on the line of the New-York State canals and the Hudson river increased, and the present great circle which bounds the trade which centers in the city of New-York will be extended. Digitized by Google 39 Admonished by the fact that a large proportion of the public works which have been completed within the last few years have greatly exceeded in their final cost the original estimates, great care has been taken to embrace in this estimate all the expenses which it is deemed probable that the completion of the work would be subject to. A liberal estimate has been made as to the quan- tities of work and materials in all the structures, and the prices affixed are believed to be sufficient to insure the performance of the work. A large margin has been given to meet contingencies ; and the estimates are submitted with the full confidence that the ship canal and basin can be constructed, upon the plan proposed, at a cost within the present estimates.

The obstructions to the navigation of the upper portion of the Hudson river seem to have attracted public attention at an early period after the Revolution. The State of New-York at last took the matter in hand, and made a beginning by an appropriation of money in 1797, between which time and the year 1818 it had ex- pended on a system of jetties or wing dams, including the sloop- lock and the dam above Troy, the sum of $148,707-100, besides private subscriptions to a considerable amount. It is stated in a report of a committee of the New-York House of Assembly, in 1818, that three plans had been suggested for the river improvement, viz: 1st. By the erection of piers or dams, as recommended by Mr. Moore, Mr. Beckwith, and the commissioners for improving the navigation. 2d. By projecting dikes or jetties, as adopted by Mr. Golborne in deepening the river Clyde in Scotland. 3d. By constructing an independent canal, on the principle of Mr. Genet. Of these three plans, the second seems to have been preferred, and to this unfortunate selection the formation or increase of many of the recent obstructions to the navigation are plainly referable. The system of jetties (if system it could be called) having sig- nally failed to produce the desired effect on the Hudson, a com- mission was appointed, in 1819, to report on the condition of the river and the best means for its improvement. Gov. Clinton, Mr. Van Buren, and Mr. Genet were members of this board, and un- der its auspices the first hydrographic survey of the river was made by Mr. Randal in the summer of the same year. Mr. Genet was permitted to present to the Legislature his indi- vidual views of the important question submitted to the investiga- tions of the commission, the other members declining to express an opinion on the merits of the projet. With his accustomed zeal and ability, Mr. Genet urged the construction of a ship canal from Greenbush to a point called Vyvede Hook, between Coey- mans and New-Baltimore, and the improvement of the bed of the river between Albany and Troy by a system of longitudinal Digitized by Google 45 dikes, as the plan best calculated to remove or rather to avoid the difficulties attending the natural navigation. Mr. Genet's proposition, although generally well received, was not adopted, and the whole matter rested till the spring of 1831 ; the jurisdiction of the federal government having been in the mean time extended over these waters by judicial decision, when De Witt Clinton, Esq., a civil engineer in the service of the United States, was directed to conduct a hydrographical survey of the Hudson river, from Waterford to New-Baltimore, under specific in- structions from the topographical bureau. The report, chart and plans, prepared in accordance with these instructions, were sent by the chief of the topographical bureau to the war department on the 30th of March, 1832, from whence they were transmitted to Congress on the same day. This plan for the improvement of the river was sanctioned by Congress, in the act of the 30th June, 1834, making an appropria- tion of $70,000 towards its accomplishment. At the request of Capt. Talcott, of the corps of engineers, who had been charged with the execution of the work, the whole sub- ject was referred to a board of engineers (composed of Col. Totten, Lieut. Col. Thayer, and Capt. Talcott), which was especially in- structed to review two projects which had been suggested ; the one by a canal, the other by deepening the bed of the river, and to give its opinion as to their relative merit and practicability, ac- companied by estimates of cost. The board of engineers, after analyzing with great skill and ability, and after discussing the two projects with much labor and detail, finally recommended that the attempt to improve the navi- gation be confined to the bed of the river. It will thus be seen that the special board of engineers recom- mended essentially the same plan which had been previously sanctioned by the topographical bureau, and transmitted to Con- gress on the 30th March, 1832, and adopted by that body in the act of 20th June, 1834. In the summer of 1836, Congress voted an additional appro- priation of $100,000 towards the improvement of the Hudson river, and directed that a pro rata expenditure of that sum should be made above and below Albany. Early in 1837, a further sum of $100,000 was granted for this object. Digitized by Google 46 In 1838, a further appropriation of $100,000 was made by Con- gress. No appropriation of money for the continuation of the improve- ments having been made since 1838, all operations were suspend- ed at the close of the year 1839, with the exception of slight re- pairs. The whole amount of money granted by Congress for the object was, $370,000 00 Of the above sum there was expended: On the 1st section (between the sloop-lock and Troy), $6,743 64 On the 2d section (between Troy and Albany), 130,234 60 On the 3d section (between Albany and Van Wie's Point), 230,313 54 367,291 78 Leaving a balance of $2,708 22 which has since been expended on the preservation and repair of the public property connected with the improvement. The sum total of the estimates by the special board of engineers for the improve- ment of the Hudson river, between Waterford and New-Baltimore, on the most perfect and expensive plan, was $819,634 10 The total amount, expended as above, was 370,000 00 Leaving a difference unappropriated of $449,634 10 For this sum,* judiciously and economically expended, I feel quite confident that a free, easy and unobstructed navigation may be obtained, at all times when the river is not closed with ice, be- tween Troy and the city of New-York.

No. 53, House of Representatives.] On the 19th of Nov., 1834, a special board of engineers convened to take into consideration the subject of improving the Hudson river, and of devising a plan to overcome the obstructions to navi- gation between Waterford and a point below Albany, to be desig- nated by Capt. Talcott, and to review two projects which had been suggested-one by a canal, and the other by deepening the bed of the river-and to give its opinion as to their relative merit and practi- * To this of course must be added whatever may be necessary to repair the works that have sustained injury, and to replace the machinery that has deteriorated in consequence of the long suspension of the appropriations, Digitized by Google 47 cability, accompanied by estimates of costs, and on the 27th of Dec. made report, from which is made the following extracts: § 13. The board approach the particular investigation of the subjects committed to them with great diffidence. Considering their want of experience in operations of the nature of those now to be examined, and the newness to them of some of these subjects, even as matters of study; considering on the one hand the incalculable benefits to result from a successful solu- tion of the difficulties, and on the other, besides the great immediate loss, the perhaps irremediable mischief that mistaken and erroneous views on their part may involve, though they shall apply their best faculties to an investigation which their duty does not permit them to avoid, they feel bound to ask, as to their results, not con- fidence but caution. § 28. In order to bring the several preceding estimates into one view, they are hereby recapitulated : 1st. Mr. Genet's project of a canal about 16 feet deep at low water, 109.8 feet wide at top, 124 miles long; Mr. Randal's estimate being increased by the supposed cost of lining the banks, cost of dredging and other work exterior to the canal, not included, $1,202,365 00 2d. A canal about' feet deep at low water and 10 feet at high water, 109 feet wide at top, 124 miles long, banks lined, no work re- quired exterior to the canal, 810,878 00 3d. A canal about 10 feet deep at low water, 109 feet wide at top, 124 miles long, banks lined, no work required exterior to the canal, 935,340 00 4th. A canal about 10 feet deep at low water, 200 feet wide at top, 124 miles long, banks lined, no work required exterior to the canal, 1,524,242 00 5th. A canal about 10 feet deep at low water, 300 feet wide at top, 121 miles long, banks lined, no work required exterior to the canal, 2,174,640 00 § 30. The board are of the opinion that the preceding examina- tion of canal projects has shown, with some precision, the relative expense at which communication of this nature, more or less ca- pacious and accommodating, may be effected; and also that, although the absolute expense is shown only approximately, this approximation is an interesting and important result. Of the practicability of either of these projects they have no doubt; and were the subject before the board confined to the im- provement of the Hudson, downward from Albany, the problem Digitized by Google 48 would be limited to a comparison of the effect of means directed in one case to the making a new channel, and, in the other, to the improvement of the natural one should such a comparison show, for example, that the means demanded for an artificial channel, of the required depth and a certain width, would give to the river an equal depth with a width much greater, the problem, so far as regards the kind of improvement, would be solved; and, on the other hand, should it appear that uncertainty as to both results and means would attend every step in the labors upon the river, it might be prudent still to consider the problem solved yielding to demands, though great, which cannot disappoint, rather than encounter an alternative surrounded by doubt and hazard. But the problem before the board is not thus simple. The canals we have been considering reach no higher than Albany; and the form of the shores above that city has, we be- lieve, been considered as restricting improvements to the bed of the river. From the materials before the board, it is, at any rate, necessary to take the supposition that above Albany the river is, if possible, itself to be improved. We are, therefore, for this portion of the navigation, necessarily driven to a choice of means of improvement from amongst a class of expedients which have often disappointed sanguine expecta- tions; it being our duty to find, if we can, one of these which will hold out the promise of fulfilling all important conditions; and as we may anticipate, from the nature of the obstructions, that any expedient which shall be found applicable above will not be less so below Albany, it will be proper to take into the investi- gation the whole range of the embarrassed navigation. § 42. ***** We also find, by the last sheet of Mr. Randal's map, that the average depth at lowest water, for one mile below New-Baltimore, is about fifteen feet, or, more accurately, that the average depth between the lines of nine feet water is 15.45 feet, which will leave a depth of 6.45 feet to be filled up of the bottom, without the least incommoding the navigation. ***** § 66. It was before stated that accurate observation as to the height of floods, their slope, velocity, &c., and as to the nature of the bottom, is indispensible, not only to a correct determination of the proportion of flood which it will be proper to keep within the restricted limits, but also to the adjustment of the several breadths of the channel. Until such observations shall have been made, neither the exact forms, lengths, nor heights of these structures Digitized by Google 49 can be determined ; nor, indeed, until the effect on the flood of moving masses of ice shall have been carefully noted, and much information collected on this last point, can the number and situa- tion of these works be regarded as fully settled. § 67. It is necessary, however, to make suppositions of some sort as to all these matters, in order to obtain our estimates. The sup- position as to situation and extent of the works are shown on the map; and we have taken for their altitudes nine feet above lowest water for those between Troy and Albany, eight feet for those be- tween Albany and Van Wie's Point, and seven feet for those below this point; all the dams and dikes being calculated as twelve feet in breadth at bottom. § 68. In our state of uncertainty as to the extent to which ice may endanger the structures, we have included in our estimate the number of ice breakers recommended by Mr. Clinton, and have supposed them to be triangular pieces, having their upper surface so inclined that the ice must pass over them and be broken as it falls. § 90. In order to bring all the preceding estimates for the im- provement of the river into one view, we here present a general recapitulation : Improvement of the river from Waterford to New-Baltimore, inclu- ding a dredged channel below Troy, 660 feet in width, $819,634 10 Improvement of the river from Waterford to New-Baltimore, including a dredged channel below Troy, 300 feet in width 671,134 11 Improvement of the river from Waterford to New-Baltimore, not in- cluding any dredging below Troy, 522,634 11 Improvement of the river from Waterford to Van Wie's Point, not in- cluding any dredging below Troy, 299,395 37 § 92 Renewing the expression of doubt as to their ability fully to master the important subject committed to them, the board, in conclusion, recommend that the attempt to improve the navigation of the Hudson be confined to the bed of the river; and that the sys- tem of works should be of the kind suggested in the preceding re- marks, being applied under the direction of a competent person, and being liable to such modifications as careful observation, during the progress of operations, shall show to be necessary or expedient.

Canaling, where it is practicable at an expense which its object will justify, is, generally speaking, preferable to every other mode of improving inland navigation, because experience has proved it to be the most sure and permanent; and if in the present instance it should be judged that the benefit to be derived from it is of such magnitude as to make its adoption advisable, the Commissioners do not hesitate to recommend it as the most efficient plan for im- proving the navigation of the Hudson below Albany. No extra- ordinary obstacles are presented to its execution, and its track indi- cates facilities which were not anticipated before it was minutely explored. DE WITT CLINTON, SIMEON DE WITT, J. V. N. YATES, M. VAN BUREN, E. C. GENET, GEORGE TIBBITS, TOWNSEND McCOUN, Commissioners. EXTRACT of a Letter from Benjamin Wright, Chief Engineer of the State of New-York, to Mr. Genet, dated ROME, June 20, 1823. " That the river, in its present state, is a bad and an expensive navigation is certain ; that the attempts which are (as is said) about to be made to deepen the channel on the bars below Albany, will answer a valuable purpose, is, to say the least, doubtful; at the same time believing, as I do most sincerely, that the permanent and effectual way of making a navigation, will be to adopt your plan of a canal parallel to the river, passing by the shoals, bars, &c. But, my dear sir, let me say that it takes time and many words to convince the public of their errors in these kind of improvements. You have lived in this country long enough to find out that every man in the community is a first rate engineer (in his own opinion), and without reflecting upon causes and effects, he makes up in his own mind a plan adapted to the case, and once settled down in Digitized by Google 51 the full belief in his own wisdom, he is tenacious to the last of his own schemes, and nothing but dear-bought experience will ever drive him from his ground. Apply these remarks to what you have seen acted over, by what was called improvement in the Hudson, in forming wing dams the last twenty years, and you will say that, at the time the plan of wing dams was commenced, nothing which the wisest and most experienced man in community could have said would have dri- ven them from that plan; and applying what has been to what will be, I set it down that a few years more must be passed over, and a few hundred thousand dollars expended in the bed of the Hudson, before the time will arrive when these self-made engi- neers will be cured of the mistaken plan of working in the bed of that river." [From McCulloch's Gazetteer, vol. 1, page 994.] "TRADE AND MANUFACTURES OF GLASGOW.-Glasgow owes its present greatness to its advantageous situation on a fine river, in one of the richest coal and mineral districts in the empire. Origi- nally however the Clyde was much encumbered by fords and shallows, and for a lengthened period it served rather to excite and disappoint expectations, than to confer any real commercial advantages to the city. In 1662, after several other schemes had failed, the magistrates of Glasgow purchased the ground on which Port Glasgow (sixteen miles lower down the river) now stands, where they formed a harbor and a graving dock, the first work of its kind in Scotland. For a considerable period, the intercourse between Glasgow and its newly acquired port was principally carried on by land carriage ; but, from 1665, attempts were ever now and then made to deepen the river. In 1688, a quay was formed at the Broomielaw; but even so late as 1775, no vessel drawing six feet of water could reach Glasgow except at spring tides. At length, however, a plan proposed in 1769, by Mr. Golburn, engineer of Chester, for deepening the river to seven feet at neap tides, was adopted. He proceeded to accomplish his task partly by the employment of dredging machines, and partly by con- structing dams and jetties, so as to confine and strengthen the Digitized by Google 52 course of the river. These measures have since then been con- tinuously and energetically followed up, particularly of late years, and with such success that vessels drawing 15 feet of water come up to the city at springs, and that there is usually a depth of five feet water in the river at low neaps. There are still four dredging ma- chines and two diving-bells in constant employment. The river for seven miles below the city is very much contracted, and forms nearly a straight line, the sloping banks, formed of whinstone, being constructed in imitation of ashler. The accommodation for shipping at the Broomielaw has been greatly extended ; but a measure is now before Parliament for adding to it by the construc- tion of extensive docks and other conveniences. The influence of these improvements on the shipping and trade of Glasgow has been most striking. Dr. Cleland says that less than 50 years ago, a few gabbards, and these only 30 or 40 tons burden, came to Glas- gow, and I recollect the time when, for weeks together, not a ves- sel of any description was to be found in the port of Glasgow.'- (Former and Present State of Glasgow, 30.) Now, however, a greater number of sailing vessels and of steamers belong to Glas- gow than to any other Scotch port, and the harbor is constantly crowded with ships from foreign ports, coasting vessels and steam- ers. The steam packets belonging to the Clyde that ply to Liver- pool, Dublin and Belfast, are among the first vessels of their class in the empire. In all, there belonged to Glasgow, in 1838, fifty- three steainers, of the aggregate burden of 6,644 tons. Subjoined is an account of the net amount of the tonnage dues on shipping coming up to the Broomielaw at different periods since 1770 Year. Revenue. Year. Revenue. 1770 £149 10 0 1830 £20,296 18 5 1780 1515 8 4 1835 31,910 19 3 1790 2239 0 4 1836 35,612 16 0 1800 3319 16 1 1837 35,595 8 3 1810 6676 7 6 1838 36,993 13 0 1820 6328 18 10 1839 43,287 16 10 a 0) The business connected with the port and the river is managed by parliamentary trustees. The gross revenue of the trust for the year ending the 31st August, 1839, amounted to £45,826 13s 6d, 1 and the expenditure, including interest for debt, to £35,694 17s 4d. The net debt due by the trust amounted, in the same period, to £122,335 2s 3d. The port dues were raised, in 1826, from 1s to 0 Digitized by Google 53 Is 4d per ton. Perhaps, on the whole, it is to be regretted that in- stead of attempting to improve the navigation of the Clyde, a ship canal had not been constructed from Glasgow to the deep water in the river; but it is now too late to think of such a measure." [REPLY of Wm. V. Many, Esq., to the inquiry asking his opinion as to how would the construction of a ship canal and basin, upon the plan proposed, affect the manufacturing interest of Albany.] DEAR SIR.-In answer to your inquiry, " How would the con- struction of a ship canal and basin, upon the plan proposed, affect the manufacturing interest of Albany ?" I reply, that in my opinion it would greatly promote those in- terests, and in the way and for the reasons that 1 will state. Many important branches of manufactures, for which the cen- tral location of Albany would afford great inducements, cannot now be advantageously carried on here, because they cannot be estab- lished on the margin of the river without being exposed toinundation and ruinous injuries at times of freshets, and the business will not bear the inconvenience and expense of being carried on at any point involving the expense of transportation of the raw material and the manufactured article to and from the river; and if the manufactories should be built up high enough to raise their opera- tions out of the reach of the high water, the expense of elevating all the raw material required to supply them would absorb too much of the profits to enable them to compete with those which have no such difficulties to surmount. As an illustration, take the article of pig iron : In some freshets the rise of water in the river in front of this city is nearly 18 feet above low water mark. To render a blast furnace situated on the bank of the river perfectly secure from all damage of floods, it would require to be raised at least 25 feet above low water. The additional cost of construction at such an elevation would be very large; but the additional cost of supplying a furnace so constructed with the raw material and fuel, would be an unceasing drain upon the profits of the estab- lishment. For every ton of pig iron manufactured, it would be necessary to raise to the height of about 25 feet two tons of ore and two tons of coal, and afterwards to let down one ton of the manufactured article and about two tons of cinder, thus making four tons to be elevated, and three tons to be let down a distance Digitized by Google 54 of about 25 feet, for every ton of pig iron manufactured. The advantages of any location not subject to such drawbacks must be obvious. Let us now see what advantages would be afforded by the banks of the proposed ship canal and basin (if constructed, as con- templated, with an elevation of 20 feet) for the location of such establishments for manufacturing pig iron. As the banks would be above the reach of freshets, and the level of the water in the canal and basin would never, at any season of the year, be sub- ject to any material variation, the furnace, if raised three or four feet above the water level, would be beyond all danger of inunda- tion. The coal and ore could be taken from the vessels directly into the works, on the same level where they would be required for use; and the pig iron and cinders could be returned on board of the boats, without the expense of lowering them from a higher level. The difference in the expenses of a large blast furnace, so situated, and of one built and conducted as it would be necessary to build and conduct it, if situated on the margin of the river, would of itself amount to a good business. Should this canal and basin be built, and these accommodations afforded for such establishments, Albany would be one of the best points in this country for the manufacture and sale of pig iron. The concentration here of so many lines of communication by water and by railways, make it a peculiarly suitable place for the manufacture, and the shipment to every part of the country, of such a heavy article, and one that involves SO great expense in its handling and transportation. Besides the inexhaustible supplies from the northern counties, the central counties of this state, lying along the line of the Erie canal, Oneida, Herkimer and others, abound in valuable iron ores (the red oxides), which are said to be more easily smelted than others; and all these could be brought to this city and landed at the manufactories on the banks of the ship canal and basin at a trifling cost, and the smelting of them, under these circumstances, would, I think, become immediately a very desirable and profitable business, in reference both to our local consumption and to sale and shipment for use elsewhere. The ores from the mines on Lake Champlain are now brought down on the Champlain canal, carried past this city, and, in com- bination with other ores, smelted in some of our more southerly river counties, such as Columbia, Dutchess, &c., and the iron thus smelted is again brought up the river to this city, and converted Digitized by Google 55 by our foundries into stoves, hollow-ware and machinery about 20,000 tons of pig iron are now consumed every year by the Alba- ny foundries alone, and the consumption is rapidly increasing. I have spoken more particularly in relation to the manufacture of iron, because it is with that branch of manufacturing that I àm best acquainted ; but the same facilities which the ship canal would afford for the successful prosecution of this branch of the iron business would be equally applicable to other branches of it. Rolling mills, and all other establishments requiring the consump- tion of large quantities of coal and heavy raw materials, would find the greatest advantage in their location on the borders of such a canal or basin, where they would enjoy all the benefits of the proximity to navigable waters, without any exposure to the rise or fall of the river. I would, therefore, consider the proposal to elevate the canal and basin 20 feet above the ordinary level of the river one of the most admirable and important features in your plan, not only in refer- ence to its direct object, but also in reference to the new and valuable accommodations it will afford for the wants of manufac- turing business in this city, without interfering in any degree with existing establishments for our present business; it will afford the best, if not the only suitable sites for new and extensive branches of business, which cannot otherwise be conveniently and profit- ably established here; and in this way, as well as by the great increase it cannot fail to give to our commercial business, it will add largely to the prosperity and wealth of this city. Very respectfully yours, WM. V. MANY. [EXTRACTS from Report made to the Water Committee of the Common Council of the City of Brooklyn, April 15th, 1852, on supplying the city with water. By WILLIAM J. MCALPINE, civil engineer.] THE PUMPING ENGINES. The duty of the engine has been calculated from the following data : The elevation of five millions of gallons of water in twelve hours, through a pipe six thousand feet long, thirty inches in dia- meter, and to a height of one hundred and ninety feet. This duty, including the friction of the machinery and of the Digitized by Google 56 water passing through the rising main, is equal to seventeen mil- lions of pounds, raised one foot high per minute, or about five hundred and fifteen horse power. An engine, to perform this duty, must have a steam cylinder of seventy-two inches diameter, and twelve feet stroke, working steam at twenty pounds pressure per square inch. Two plunger pumps are proposed to be driven by this engine and to make provision for the leakage, after the valves become worn, they must be three feet diameter and eight and one-half feet stroke. The details of these calculations are given in the appendix to this report. The plan of the engine is shown in the drawings which accompany this report, and is essentially the same as that which I prepared for the Dry Dock at the Brooklyn Navy Yard. In the drawing, the engine has been represented with side levers instead of a working beam, and the fly-wheel shaft has been placed on top of the engine frame. I have proposed to modify this plan in both respects; but as these changes will not increase the expense of the work, it is not regarded as important at the present time to make the correction. The engine has been calculated for a slow motion, low steam, and for working but twelve hours per day. As the demand for water increases, the engine may, with safety, be run faster ; higher steam may be used ; and it may be run more than twelve hours per day. Its capacity may thus be in- creased so as to elevate seven and one-half millions of gallons per day. When the demand increases beyond this quantity, another en- gine and pumps will be required. From the estimates which are herewith submitted, it will be seen that there has been allowed the sum of thirty-seven thousand two hundred and fifty-five dollars ($37,255) per annum for the ex- pense of running an engine capable of elevating five millions of gallons of water in twelve hours, which sum includes all the ex- penses of labor, fuel, oil and miscellaneous items. Some other plans of pumping engines have been suggested for application to this work, which possess strong merit, and which, on further examination, may be found to be more economical and better adapted to this duty. As these engines have not been tried on so large a scale as would be required for this undertaking, it has been deemed best to base the estimates on well known plans, Digitized by Google 57 the working of which has been ascertained by the experience of many years.

The cost of elevating one thousand gallons of water one hun- dred and ninety feet high, by the first engine, is two cents. CALCULATIONS OF THE DUTY AND DIMENSIONS OF ENGINES AND PUMPS. The formula used in calculating the power necessary to overcome the resistance caused by the friction of the water passing through long pipes, is that given by Mr. Hawksley, in his evidence before the Commissioners appointed by the British Par- liament "to inquire into the state of large towns and populous districts," and is as follows: Q3l P 140 d⁵ 8 Digitized by Google 58 When P represents the horse power necessary to overcome the friction, Q repre- sents the gallons delivered in one second, l the length, and d the diameter of the pipe, both in inches. The formula for the computations of the power of the condensing engine is taken from Haswell, as follows: (P+v) - (f+m)xS-nb=L Where P represents the mean effective pressure, and v the vacuum upon the steam cylinder piston, f represents the pressure upon the piston necessary to overcome the friction of the engine, and m that of the air-pump piston; 8 represents the velocity of the steam cylinder piston, and n that of the air-pump piston, in feet per minute and b the resistance of the vacuum against the air-pump piston.

The water was lifted an average height of fifteen feet. The engine made nine and a half revolutions per minute. The pressure of the steam in the boilers was six pounds per square inch, at starting, and gradually in- creased to twelve pounds. The fires were burning four hours before the engine was started, and consumed in that time fifteen hundred pounds of coal. The engine was stopped several times to shore up the vessel, the "Mississippi," during which there was fourteen hundred pounds of coal consumed. Under these very unfavorable circumstances, the duty was equal to raising two hundred thousand pounds of water with one pound of coal. Digitized by Google 60 COMMUNICATION FROM WILLIAM A. PERKINS. ALBANY, January 24th, 1852. OCTAVE BLANC, Esq., Sir - In accordance with your request of October last, " to furnish such information as was at my command, in re- ference to the capacity of the Normanskill, and the feasibility of converting the said stream into a feeder to the proposed ship canal, to extend from Albany to New-Baltimore," I make the following communication: The total area of catchment to the Normanskill has been some- what carefully ascertained to be one hundred and forty square miles; and the composition of the soil of this surface is generally so compact and impervious as to warrant the use, in the accompa- nying calculations, of the greatest proportion between the available and falling water heretofore adopted by engineers, in similar com- putations for other parts of the State. The quantity required for the operation of the canal is set down as sixteen thousand cubic feet per minute, for a period of six months; or a total of 16,000 X 60 X 24 X 180 = 4, 147, 200,000 cubic feet for each year. The yearly rain fall, as recorded at the Albany Academy, for the years 1836 to 1850 (both dates included), was as follows: Years. Inches. Years. Inches. Years. Inches. Years. Inches. 1836, 44.65 1840, 44.38 1844, 35.00 1848, 48.22 1837, 41.17 1841, 37.85 1845, 39.45 1849, 36.72 1838, 42.03 1842, 45.99 1846, .... 39.85 1850, 50.97 1839, 38.11 1843, 48.35 1847, 41.38 An inspection of the foregoing table will justify the assumption of forty inches per annum as the reliable quantity of rain and snow falling upon the district in question for any one year. In determining the amount of available rain fall, we have the following data as our guide: Cochituate Lake (Boston Water-Works), 44 per cent. of falling water available. Eaton Brook Reservoir, Chenango Canal, 50 " " " " Madison " " 66 " " " " Rensselaer Lake, Albany Water-Works, 55 " " " " Watervliet " " " 42& 49 " " " " It is therefore a safe estimate in using fifty per cent. of the fall- ing water, to compute the capacity of the stream. Thus we find the annual yield of this district of one hundred and forty-five square miles, equal to : Digitized by Google 61 43,560 x 1 I X (145 x 640) 6,737,280,000 cubic feet. Quantity required for Canal, 4,147,200,000 " Leaves the amount of 2,590,080,000 " discharged annually through the stream, and not required for the supply of the canal. For the purpose of diminishing the capacity of the storing reser- voirs, and leaving unimpaired the several water privileges in the Kill, it is necessary to waste the above quantity of 2,590,080,000 cubic feet, during the suspension of navigation and the follow- ing table is given to show the yield of the stream, for three of the past fifteen years, when the greatest winter fall of snow and rain occurred. The coldness of this season, and the periodical rapid condensa- tion of snow, have induced me to place the available supply at sixty, instead of fifty per cent. of the total water falling.

But it is proper to state that there has occurred several seasons when the above daily supply would be reduced, for quite a period, to one-half that amount; although leaving, at the same time, a sufficient supply for milling purposes. From the above table it appears that there must be provided a reservoir capacity of 2,850,275,600 cubic feet, to receive and re- tain the greatest surplus which would accumulate in the six months ending the first of May for any one year. And by applying this amount to the following table, made from Digitized by Google 62 the quantity of rain fall, in the year when the largest and most irregular summer discharge of water through the stream would take place, we determine, if there be any, the additional capacity of reservoirs required.

Sixty per cent. of this fall, on an area of 145 square miles, gives an available supply of 2,560,000,000 cubic feet, or the quantity which is required for running the mills during the same period. Thus there is no surplus left for storage on the first of May ; and in that event it is evident that the reservoirs must only have the capacity for retaining the surplus of the summer months, which will be found, from columns 6 and 7, table No. 2, to equal 1,373,600,000 cubic feet. From the above reasoning, it is evident that if provision is made for storing 2,850,275,600 cubic feet of water, the regimen of the Kill may be so fixed as to yield an abundant supply for the ship canal. Digitized by Google 63 I am convinced, from an intimate knowledge of the region un- der description, that there may be found several sites for retaining reservoirs, in which the water may be made to have an average depth of thirty feet. Consequently the number of acres to be flooded, and otherwise occupied for these artificial lakes, will equal (2,850,275,600) ÷ 43,560 = 2181. I do not deem it necessary to provide for more than six reservoirs, which will contain the above named quantities; and from careful estimates, prepared under my direction, while examining the same source for the purpose of supplying the city of Albany with water, I feel warranted in giving the following estimates, as amounts fully equal for the conversion of the Normanskill into a feeder for the ship canal, and which will furnish all the water required : 2,181 acres land, at $100, $218,100 00 6 dams, of hydraulic masonry and earth embankments, 180,000 00 All other structures and appurtenances, 30,000 00 Total, $428,100 00 I do not insert any sum providing for damages to water power ; and as the foregoing remarks prove that all the present hydraulic privileges will be but slightly impaired, it is unnecessary to increase the above total by any material sum. Respectfully submitted, WM. A. PERKINS, Civil Engineer. COMMUNICATION FROM DANIEL C. JENNE. UTICA, Dec. 25th, 1852. Hon. WM. J. MCALPINE, Dear Sir - At the request of Isaac D. Colman, Esq., a civil engineer, I have very hastily examined the maps, plans, es- timates and report, prepared by Octave Blanc, Esq., also a civil engineer, and himself, relative to a ship canal from the city of Albany to the village of New-Baltimore, on the Hudson river ; and am very happy to give my approval of the plans and general char- acter of the work, and of the matters set forth in the report. The plans of mechanical work, so far as matured, are in my opinion well adapted to the work contemplated. An important item in all structures of the kind proposed is a suitable prepara- Digitized by Google 64 tion of the foundation on which the structure is to stand ; this part is well devised, and, if constructed as designed, there can be no failure of the structure; and this remark applies to the general details of all the mechanical structures, to the docking proposed to the protection of the prism of the canal, and to the construc- tion of the embankments. I have also examined the estimates for the necessary quantity of water required to supply the canal, and believe that ample pro- vision is made for that object, providing the work is constructed on the plan contemplated. Very respectfully, DANIEL C. JENNE, Civil Engineer. COMMUNICATION FROM I. NEWTON. NEW-YORK, January 26, 1853. I. D. COLMAN, Esq., Dear Sir - I have to acknowledge the receipt of your favor of the 18th inst. In answer to your inquiry, " What, in your judgment, would be the effect on the cost or expense of transportation between Albany and New-York, were the navigation so improved between Albany and New-Baltimore as to admit of the free and uninterrupted pas- sage of vessels to and from the two last mentioned places ?" I would beg leave to say, that I have not a doubt but that the carrier would be able to make a reduction of 25 per cent., and then be left with as much profit as he now gains. In this estimate I take into account his loss of time, damage and increased risk in navigating, as the river has been heretofore. Besides this benefit in navigating without interruption, is the saving in time to the owners of the millions of property passing up and down the river. In much haste, I remain Truly yours, I. NEWTON.
