largest specimen lacks the tip and is made from a grayish-brown 

 quartzite (pi. 50, /). It measures 20 mm. long (estimated), 18 mm. 

 wide, and 5 mm. thick. The other point (pi. 50, e) , made from a crys- 

 tal clear quartz, is 15 mm. long, 17 mm. wide, 4 mm. thick and weighs 

 1.8 gm. Both points were recovered from the 1.0-1.5 foot level in 

 square N145W45. 



Group 2. Triangular^ comer-notched {four specimens). — None are 

 complete, but all show straight to slightly convex sides. Evenly 

 placed, bifacial flake scars extend outward at right angles from the 

 longitudinal axis to the side edges. One point, broken almost its en- 

 tire length down the long axis, has a slightly convex base (pi. 50, p-). 

 It is made from a brown chalcedony, but one face is completely coated 

 with a white patination. The specimen measures 38 mm. long, 27 mm. 

 wide (estimated), and 5 mm. thick; it was located at a depth of 1.3 

 feet in square N125W70. The next piece also has a convex base, but 

 lacks the tip portion (pi. 50, h). It was made from a very fine- 

 grained, light-brown quartzite and measures 32 mm. long (estimated), 

 24 mm. wide and 4 mm. thick. The specimen was recovered 2.2 feet 

 below the surface in square N175W50; it is similar to a point (Cata- 

 logue No. 43) found at site 39BE11, Brule County, S. Dak. The 

 third specimen, made of basalt, lacks the base, and the tangs were acci- 

 dentally broken off in the laboratory (pi. 50, ^). It was located at a 

 depth of 2.3 feet in square N190W40. The fourth piece, made from a 

 fine-grained, olive-drab quartzite, consists only of a point section (pi. 

 50, j). It was recovered from a depth of 1.8 feet in square N150W35. 



END SCRAPERS 



(10 specimens) 



Group 1 {four specimens'). — All are planoconvex in cross section, 

 ovoid in outline, show little or no secondary flaking on the convex 

 surface, and have been retouched at one end and both side edges. The 

 first specimen (pi. 50, ^), made from a gray chalcedony, is 40 mm. 

 long, 28 mm. vtdde and 7 mm. tliick. It was located at a depth of 2.3 

 feet in square N155W15. The second scraper (pi. 50, ?), made from 

 a brown chalcedony, is patinated on the convex surface. It measures 

 35 mm. long, 29 mm. wide, 10 mm. thick and was recovered from the 

 1.5-2.0 foot level in square N155W25. The third piece (pi. 50, m), 

 also made from a brown chalcedony, is patinated on the base and 

 along the side edges. It measures 26 mm. long, 12 mm. wide, 7 mm. 

 thick and was fomid in the 1.0-1.5 foot level at square N135W50. The 

 fourth specimen has been fractured opposite the working end ; it was 

 made from a brown chalcedony and is heavily patinated on the convex 

 surface (pi. 50, n) . The fragment measures 22 mm. wide, 9 mm. thick 

 and was located in the 1.0-1.5 foot level at square N145W40.
