similar to that in the other pit, but it became not only limy, 
with debris from limestone and with loess-kindchen, but also 
much more light-colored, almost light yellowish, and finer- 
grained acting like putty. The coarser material was plainly 
much rotted, but also apparently originally water-worn. In this 
pit therefore, though not in all its features, nor in so pro- 
nounced a condition, we have essentially the repetition of 
Fowke's trench. We saw no stratification, but in the bottom 
is apparently the talus lying on the bedrock, with a darker 
band, gravelly and calcareous, which is apparently the ana- 
logue of the dark band overlying the geest in the tunnel. We 
did not actually reach the bedrock, but stopped amongst fallen 
limestone masses some of which were about three feet long. 
If it should be desired to further demonstrate the wide ex- 
tent of the "little relic-bearing deposit," it will be necessary to 
make further testing of the loess in the vicinity. The testing 
above mentioned is not deemed sufficient to complete such 
demonstration. 
Further niieroseopica! examination. 
Samples were collected as follows, including those already 
mentioned. 
No. I. On tlie floor of the tunnel near the point where the skel- 
eton was found, but to the eastward, i.e. at the entrance of the oflfsct 
tunnel, supposed geest, enclosing rotting limestone masses. 
No. 2. Loess from the wall of the tunnel about seventy feet from 
the entrance, above the horizontal silt layer. 
No. 3. Loess from the" roof of the tunnel, at about seventy feet 
from the entrance. 
No. 4. From the silt layer at the entrance. 
No. 5. Laminated' loess, St. Joseph, from the foot of a remnant 
of a high spur of loess, between the depot and the river, perhaps a few 
feet below the railroad grade. 
No. 6. Concannon tunnel, station B, to illu-'tratc the darker part 
of No. ic. 
No. 7. From No. 4a at station C. 
No. 8. From No. ic at station C. 
No. 9. Rotted limestone piece four inches across from No. ic at 
station C. 
No. ID. Carboniferous shale at station G. 
No. II. Fine sandy loess without structure, at twenty or thirty 
rods south from Concannon's house, and about 100 feet above the bot- 
tom land, three feet from the sm-face.
