[January 19, 
I do not presume to boldly assert that America’s early man, 
at least on the Atlantic coast, was jt?re-glacial ; but that he ante- 
dates the Red Indian, if it be true that the latter is a recent comer , 
I do confidently maintain, backed «as I am by the unquestionable 
testimony of the Trenton gravel. 
THE ARGILLITE IMPLEMENTS FOUND IN THE GRAVELS 
OF THE DELAWARE RIVER, AT TRENTON, N. J., COM- 
PARED WITH THE PALAEOLITHIC IMPLEMENTS OF 
EUROPE. 
BY HENRY W. HAYNES. 
The first question to be decided in regard to the rude imple- 
ments, mostly made out of argillite, and alleged to have been 
discovered in the gravels of the Delaware, is as to their authen- 
ticity. Were they actually found where, and under the circum- 
stances in which, they are claimed to hay e been discovered ? Upon 
this fundamental point we are not restricted to the unsupported 
testimony of a single observer, whose prepossessions may possibly 
have misled him, or whose observations may be objected to as 
lacking in exactness. In addition to the very extensive series of 
these objects found by Dr. Abbott, Professor Putnam, Mr. Carr 
and Professor Whitney all alike report that they have discovered 
precisely similar objects themselves, in the same localities and 
under like conditions. 
During the past autumn I visited the region myself in company 
with the Rev. Geo. Fred. Wright, Professor W. Boyd Dawkins, 
and Mr. H. C. Lewis, of the Penn. Geol. Survey, under Dr. Abbott’s 
guidance. Several implements were taken by the others, either 
from the gravel, or the talus on the river bank, in my presence, and 
I found five myself. All these objects were precisely similar 
in appearance, material and method of fabrication, to those placed 
by Dr. Abbott in the Peabody Museum at Cambridge. They 
were all found under exactly the same circumstances, and in like 
situations, as were the greater part of those described by him in the 
two accounts of his discoveries published in the Reports of the 
Museum for the years 1877 and 1878. Other examples, however, 
were taken by him from undisturbed gravels at varying depths.
