[Haynes. 
For my own part I consider it absolutely and incontestably 
established that these objects have come, as alleged, from the 
gravel-beds of the Delaware valley, and that occasionally only have 
they been found on the surface. . 
A second question then arises in regard to the character of 
the objects themselves. 
Do they show incontestable marks of human workmanship ? 
This is a problem to be decided only by the verdict of such per- 
sons as have had large experience in searching for and studying 
pre-historic stone implements, and who have thus acquired the skill 
of the expert in discriminating between the natural and the 
artificial fracture of the various kinds of stone out of which the 
early man manufactured his first rude implements. I venture to 
offer my own opinion upon this question because I think my op- 
portunities for this kind of study have been unusually great. For 
six years I have studied the stone age in various countries of 
Europe, in all of them searching diligently for implements, and I 
have handled stones artificially broken literally by the hundreds 
of thousands. I have also carefully examined the celebrated 
collections of such objects to be found in the various museums 
of different countries, and I have enjoyed the personal acquain. 
tance and companionship of many of the leading cultivators of pre- 
historic studies. In this way I have participated in a great deal 
of inquiry and discussion in regard to the characteristics and 
peculiarities which such implements present. Applying the 
experience thus acquired, I trace many striking resemblances 
between these argillite objects and the palaeolithic implements 
of Europe, made from flint or quartzite. It is undeniable that 
the argillite implements are of ruder workmanship, but I think 
this arises solely from the circumstance that the material from 
which they are fabricated is much less susceptible of being finely 
worked. Especially is the flint derived from the chalk , of which 
nearly all the European implements are made, capable of being 
chipped into much more perfect and symmetrical shapes than 
is the coarse-grained variety of clay-stone, from which the New 
Jersey implements are fashioned. But the types of the two 
classes of implements are remarkably similar. To whatever 
uses and purposes the European implements were capable of
