and shows clearly how much of it projected from the ground. The
under part preserves the original exterior characteristics of the
aepolite.
This specimen when discovered lay slightly imbedded or per-
naps indented in the coarse material at the bottom of a shallow
saucer-shaped depression, formed partly by the efforts of the na-
tives, and partly by the piling up of the triant stones brought by
them during many generations for use as hammers.
The ciroumference of this pile of stones at the base is some
60 yds., and its height from the toe of the down hill slope to the
top is 18 or 20 ft. The contrast between the smooth, rounded
greenish trap cobbles and the rough angular lichen covered gray
gneissose rocks of the vicinity, is very striking. When viewed
from across the valley, one is reminded of the pile of debris us-
ually to be seen at the mouth of a mine shaft.
The surface of both aerolites is dark brown in color
interspersed with greenish pits, and resembles bronze. To the
eye the appearance of the metal seems the same in both, a dense
tough fibrous soft iron or mild steel, with silvery luster and res-
onant as a bell. The homogeneousness of the metal is surprising.
There is apparently not so much as a single grain of any foreign
substance in the entire mass of both aerolites. The metal can be
cut with a knife, and when scraped with knife or file shows a
bright silvery luster. Etching with acid brings out the char-
acteristic Widmanstattian figures, and analyses show the typical
