vex edges and Straight base, more than usual thickness, rude appear- 

 ance. The huge and irregular flaking marks it as something different 

 from the former si)ecimens. Its plane is twisted nearly 

 one-half an inch. There is no evidence of use. Fig. 



119 is leaf-shaped, convex 

 but not rounded base, broad 

 in i)roportion, with convex 

 edges and sharp point. 



Fig. 120 is pale blue, 

 almost white, chalcedonic 

 flint, from Flint Kidge, 

 Licking County, Ohio. The 

 characteristic small (juartz 

 crystals are to be seen on 

 its surface. Its base and 

 edges are both convex, as 

 shown in the illustration. 

 The edges all around have been chipped so 

 thin that the light will show through. Dr. 

 Eau has said this was 

 probably a knife, and it 

 may have been, but there 

 is nothing except its com- 

 parative width to indicate 

 anything different from 

 any other implement of 

 the same class, and what 

 it might have been is de- 

 terminable only by the 

 shaft or handle. If it had 

 a long shaft, then this was 

 an arrow or spear; if a 

 short handle, then it was 

 a knife; and as to which 

 it had we know nothing, 

 either by direct or cir- 

 cumstantial evidence. 

 Figs. 121 to 123 are speci- 

 mens belonging to this 

 class, but have no particu- 

 lar characteristics. They 

 are inserted for the purpose of completing the 

 series. Their material, si/e, and locality are given at length in their 

 legends.
