has alleged the discovery of artificial ar- 
gillite flakes, and other relics of human 
handiwork, in a yellow sand of supposed 
glacial age under a surface loam stratum 
indicating Indian occupancy. 
Five trenches (Trench A, 214 ft. by 32 
ft. by 3 ft. 3 in. deep; B, 72 ft. by 44 ft. by 
3 ft. 3 in. deep; C, 6 ft. by 6 ft. by 2 ft. 8 
in. deep; D, 44 ft. by 4% ft. by 3 ft. 3 in. 
deep), sunk over an area 90 ft. long by 33 
ft. broad,* well upon the flat summit of the 
terrace, with Trench D, about 80 ft. from 
the outer brink, revealed clearly: 
Layer 1. 
(10 inches to one foot). 
A discolored surface loam, disturbed by 
recent cultivation, mixed with the remains 
of the Indian and white man. It contained:

being seconded by the kindness of the owners of the 
property, the Misses Lalor, who generously placed 
their land at our disposal. Dr. Charles C. Abbott 
was continually present, and Dr. Harrison Allen, of 
the Academy of Natural Sciences, of Philadelphia, 
visited the Trenches on Sunday, June 27th.

Below layer 1, and as the chief center of 
observation and interest, rested 
Layer 2 
(18 inches to 2 feet). 
Composed of a fine yellow sand, streaked 
towards its lower portion with fine irregu- 
lar films of reddish sandy clay which thick- 
ened and coalesced at the bottom into a dis- 
tinet harder red band. 
Advancing slowly into layer 2 with trowels 
against the sides of the trenches where the 
stratification had been exposed in vertical 
section, we pulled out one by one the pebbles, 
broken stones and artificial chips, ete., de- 
scribed below, giving special attention to the 
large pebbles and the chips most artificial in 
appearance, calling the attention of all our 
colleagues to each large object, when it first 
clinked against the trowel’s edge so that its 
depth could be measured and its position 
with reference to the clay films, observed 
by us all before its removal. 
The objects thus found (after discarding 
those resting in the upper part of the layer 
for about four inches below the bottom of 
layer 1 as pertaining to what we called the 
zone of doubt) were as follows: 
ARTIFICIAL FLAKES.
