1887.] 423 [Putnam. 



sively, a few more chips have been struck from the stone until in 

 this last, as rude as it is, there is none of the original surface of 

 the flint remaining ; while in the first from Ohio, only a portion of 

 the surface of the pebble has been chipped or broken away, some- 

 what as in the specimen from St. Acheul represented by Mr. Evans 

 on his plate n, fig. 15. 



The two specimens to which I shall next call your attention were 

 evidently designed as rude cutting implements to be held in the 

 hand. They are remarkable for their close agreement in size and 

 form, and outline of their slightly abraded cutting edges, yet one is 

 of argil lite from Trenton, and the other is of quartz from Little 

 Falls. 



As remarkable instances of identity in form and material, and 

 close agreement in size, of implements from distant places, are the 

 two well chipped pebbles of black chert ; one from the gravel of 

 Ohio and the other from that of New Jersey. The latter is fig- 

 ured in Dr. Abbott's volume (Primitive Industry, fig. 423). These 

 closely resemble the ovato-lanceolate implement of flint from St. 

 Acheul, figured by Mr. Evans (plate n, fig. 12). 



Of similar interest are the two small ovate implements of white 

 quartz, one from Trenton and the other from Little Falls. These 

 again have their representatives among the flint implements of 

 Great Britain, both as to size and shape, as shown by Mr. Evans* 

 figure 452. The shoe-shaped implements (similar to fig. 429 of 

 Mr. Evans' volume), flat upon one surface, and high at one end and 

 chipped to the " toe " or point and over the front of the " foot," are 

 found in Trenton chipped out of pieces of argillite. The specimen 

 from Trenton, and the one of flint placed with it from St. Acheul, 

 are interesting for their close resemblance in size and shape and 

 uniformity of chipping. 



Of the irregular ovate implements, like those called by Dr. Ab- 

 bott " turtle backs " (fig. 444 of Primitive Industry), there are be- 

 fore you a specimen of argillite from Trenton (the original of Dr. 

 Abbott's figure), and one of the same size and shape, but of flint, 

 from St. Acheul. These two specimens, although of different size, 

 are interesting from the fact that while the}^ each have heavy buts, 

 the opposite end of each is chipped to a rounded cutting edge, and 

 they are nearly identical in form. Of a similar form is the British 

 implement represented by Mr. Evans in his figure 418.
