PLATE VIII. 



Figs. 57, 58. — Knife blades of yellow chert. 



Fig. 59. — One of the most interesting implements found, consisting of the 

 half of an iron ax head, five and one-half inches long by one and a 

 quarter wide at its greatest width, and five-eighths of an inch thick. 

 This, by some mischance, had been split in two longitudinally, and 

 was arranged with a groove around it instead of an eye like our 

 modern axes have. 



Fig. 60. — A fine grinder of conglomerate, eleven inches long. Shows 

 much usage. 



Fig. 61. — The half of a clam shell, plainly showing saw-tooth marks 

 where it was divided. This was found at the bottom of the twelve- 

 inch hole in room V. 



Fig. 62. — Diagram of pattern on pipe bowl shown on plate VI, figure 15. 

 Impression was made on clay and photographed. 



Fig. 63. — Base of deer antler, which has evidently been used as some im- 

 plement. 



Figs. 64 to 69, inclusive. — Specimens of charred corncobs. Figure 59 

 shows some well-developed kernels on it. 



Fig. 70. — Bone implement, well worn.

 finger tips. 



Fig. 72. — Baked clay marble, evidently used in some game.
