utilize the more difficultly wrought minerals in fabricating stone imple- 
ments, and thereby reached the polished stone period. In this way, the 
two forms would be necessarily mingled; but it must be remembered 
that as a rule the two forms are not associated. Where one paleo-. 
lithic implement is found upon the surface, a hundred are quite deeply 
imbedded in the soil, and in the underlying gravels. — CHARLES C. AB-

InpiaAn Graves IN New Jersey.— The graves of Indians found 
here in central New Jersey vary to a considerable degree, and suggest 
the probability that tribes having different burial customs successively 
occupied this territory. On the terrace that faces the east side of the 
Delaware River, below Trenton; where I have gathered thousands of 
stone implements, the graves are to be detected by the discoloration of 
the soil and the little series of relics that were deposited in each grave. 
These graves, now a foot or more deep, were in all probability “ surface 
burials,” i. e., the body, encased in skins and covered with bark, was 
placed on, not in, the ground. In time the grave would become covered 
with leaves and sand, and so gradually be covered with a thin layer of 
vegetable mold and earth. The gradual increase in the depth of the soil, 
which is ever in progress in wooded countries, would result in making 
the surface burial really an inhumation, and as such we now find it. 
This shallow grave, with every vestige of the skeleton long since gone, 
‘and simply indicated by a few arrow-points, an ax, and possibly a pipe, 
bears every indication of antiquity, and yet doubtless is simply the grave 
ofan Indian. ‘There is one feature connected with these graves and the 
scattered relics, as we find them, that deserves attention. The rude 
‘implements, never polished, and made of the river rock, which we have 
maintained were strictly paleolithic implements, are never found in these 
graves, or in any graves that we have examined. Had these ruder 
implements been used as a general thing, at the same time that the pol- 
ished celt and jasper arrowheads were made, then they would likewise 
have been deposited in the graves; for the contents of an Indian grave 
are the implements and ornaments the occupant used and wore during 
his life-time. Like the implements themselves, these graves are proofs 
of the great antiquity of man’s origin along the Atlantic coast of 
America. — CHARLES C. Apsortt, M. D.
