not on a comparable basis. However, the yield per square foot in 

 trench A was greater. The proportions average i specimen to 0.9 

 square foot for trench A, and i specimen to 6.5 square feet for the pit. 

 Cut and split animal bones occurred in sections i, 10, 11, 12, and 

 ]6. Those in lo, ii, and 12 did not constitute a continuous deposit 

 through the three sections. In 10 the bones extended across the trench 

 from the middle of the section to within a few inches of the face of 

 number 11. In the latter they were along the west wall in the half 

 towards the face of 12. Those present in the bottom of 12 started i 

 foot (30.48 cm) beyond the face of the section and continued for 6 

 feet (1.828 m) along the east wall. The lens extended into the trench 



2 feet (60.96 cm) from the east wall. The bones from the first 

 sections were very fragmentary and in a poor state of preservation. 

 Those in 10 were in better condition and indicated that they came 

 from several young bison. The implements and chips of stone in the 

 section were intermingled with the bones. In section 11 were numerous 

 small fragments, most of which show the effects of burning or at 

 least are partially charred, and a number of bison foot bones which 

 had been split. Several large stones, hammers and choppers, accom- 

 panied the bones. The material in 12 consisted of exceedingly scrappy 

 fragments, presumably bison but too shattered for identification. 

 Section 16 contained a few scattered pieces w^hich appear to be from 

 the leg bones of a bison. 



The bottom of trench B had a more gradual slope than did the 

 bottom of A, owing to the fact that the ridge which crossed A in its 

 sections 5 to 9 was not present in B. Trench B ranged in depth from 



3 feet (.914 m) at the upper end to 7 feet 6^ inches (2.298 m) at the 

 face of section 16, where work was stopped. Sections i to 7 (fig. i), 

 trench B, gave distinct evidences of the channel of a small stream that 

 formerly meandered down the slopes across that portion of the ter- 

 rain. The flow was probably intermittent, water being present only 

 after heavy rains or when the snows of winter were melting, and con- 

 sisted of the run-off from the higher ground above the site. The run- 

 let had changed its course and size several times. Originally it had 

 swung in a slight curve from west to east through section 2 to section 

 I. Owing to subsequent filling and widening, it moved down the slope 

 to section 3. where its course turned to such an extent that it followed 

 the direction of the trench through sections 4, 5, and 6. In section 7 

 it swung oft' toward the west again and passed beyond the bounds of 

 the trench. Considerable quantities of clay were deposited in the 

 channel, and after it had become appreciably shallower the water 

 again began to cut, although it formed a much smaller bed along the
