hammerstones and rubbing stones, and worked bones. Pieces of 

 hematite show the effects of having been rubbed for pigment. There 

 are numerous flakes, too nondescript in character to be called imple- 

 ments, which exhibit signs of workmanship. The collection also con- 

 tains a large number of channel flakes, the long spalls removed in the 

 fluting of the projectile points. Varieties of stone represented in the 

 implements are jasper, chert, chalcedony, moss-agate, quartzite, petri- 

 fled wood, geyserite, limonite. granite, quartz, and sandstone. Most 

 of the chipped tools, the cutting and penetrating implements, were 

 made from the chalcedony, chert, jasper, moss-agate group, the " flint " 

 of the amateur collectors. This type of material is well adapted for 

 use in tools and wherever available constituted the preferred stone of 

 the implement fashioners. The harder quartzite and petrified wood 

 were employed but, in addition to being more difficult to work, did 

 not produce as good finished products. On the other hand, they were 

 better for hammers and mauls, and numerous examples show that 

 they, as well as the quartz and granite boulders, were used for that 

 purpose. Sandstone is suitable only for rubbing, polishing, and 

 sharpening bone tools and was so employed at this site. 



The percentages of specimens found at the various places where 

 excavations were made is as follows : Trench A, 37.6 percent ; trench 

 B, 15.2; the big pit in the ravine bank, 17.5; the bison pit, 4.4; the 

 small trench east of sections 3-5, trench A, 10.7 ; miscellaneous, scat- 

 tered surface finds and specimens scratched out in prospecting along 

 terrace edge and ravine bank, 14.5. 



There is an interesting range in the size and variety of points 

 (pi. 4). This group constitutes 11.3 percent of the specimens in the 

 collection. The predominant type of point is the characteristically 

 fluted Folsom in its two forms, the long and slender one with tapering 

 tip, and the short, broad style with the maximum breadth of blade 

 occurring close to the tip end." Although most of the specimens are 

 fragmentary examples, there is sufficient material to show that the 

 two forms were about equal in number. The short, stubby examples, 

 designated form A in the preliminary paper, range in size from one 

 with a length of 22.5 mm, breadth of 14 mm, and thickness of 3.5 mm, 

 to one with a length of 70 mm, breadth of 35 mm, and thickness of 

 6 mm. The long, slender specimens, the B form, have a range be- 

 tween one with a length of 23.5 mm, breadth of 13 mm, and thickness
