782 The American Naturalist. . [October, 
A trench three feet deep and three feet wide was dug from 
the face of this bluff backwards about thirty or forty feet. The 
upper twelve inches of this trench consisted of sand discolored 
with vegetable decomposition, which had evidently been dis- 
turbed. In this stratum there were found two flint arrow- 
heads or spear-heads, one argillite chip, and one flint chip, 
together with a fractured pebble, four pieces of pottery, and a 
piece of charred bone. 
The lower two feet of the excavation, except where inter- 
rupted by a pit, consisted of compact sand distinctly stratified, 
which had clearly been undisturbed. In this was found at 
varying depths one imperfect argillite implement, about three 
inches long and an inch and a half wide and a quarter of an 
inch thick, with five unrolled and angular fragments of argil- 
lite, two of which bore pretty clear evidence of having been 
chipped by human hands’ These were the only fragments. 
There were no chippings or fragments of flint or jasper in the 
lower two feet of the excavation. 
This brief paper of Professor Wright was but the prelude to 
bring out from Professor Putnam a fuller statement of the 
results of Mr. Volk’s work on the Lalor farm. For two years 
Mr. Volk has been carrying on similar excavations over adjoin- 
ing parts of the farm where the situation is similar to that 
described, and with corresponding results. Flint and jasper 
implements and flakes are abundant in the upper twelve inches 
of the soil, while no flint or jasper occurs in the lower two feet, 
of undisturbed sand and gravel. A large number of boxes of 
implements and fragments accumulated by this work of Mr. 
Volk have been sent up to the museums above mentioned ; 
but, owing to the lack of time, Professor Putnam has not yet 
opened them and published the results. But in preparation 
for this meeting Professor Putnam had requested Mr. Volk to 
pursue further investigations and send the results to him at 
Buffalo. These were presented by Professor Putnam in a paper 
from Mr. Volk describing between thirty and forty argillite 
implements and fragments which had been found in his sub- 
sequent excavations in the undisturbed lower two feet of sand, 
as described in Professor Wright’s excavation. As in that
