in width from 13 mm. to 23 mm., and in thickness from 3 mm. to 

 10 mm. One specimen (field cat. No. 2407) has a burinlike base. 



Flat end scrapers (pi. 26, A, a-f). — Thirty-three specimens are in 

 this group. All were made of comparatively thin flakes. Measure- 

 ments show that they vary in length from 15 mm. to 38 mm., in widths 

 from 16 man. to 30 mm., and in thickness from 4 mm. to 9 mm. The 

 retouched surface may be straight or curved. 



Thumbnail end scrapers (pi. 26, A, g-z). — Twenty-two specimens 

 are in tliis group. Most are very small and very well made. They vary 

 in outline from trianguloid to rectanguloid. In length they range 

 from 14 mm. to 23 rom., in width from 12 mm. to 19 mm., and in 

 thickness from 3 mm. to 7 mm. The average length runs from 17 

 mm. to 19 mm. The average widths can range between 14 mm. and 



17 mm. ; and the average thickness is about 5 mm. 



Beveled retouched edge end scrapers (pi. 26, B^ a-i). — There are 

 two types of these scrapers: those that slope upward to the right 

 and those that slope to the left. Nine specimens have retouched edges 

 that slope to the left whereas only six slope to the right. Whether 

 these are valid types can only be verified by examination of other 

 nearby collections. Most of the ventral surfaces are flat, but there 

 is an occasional one that is planoconvex in outline. 



Those scrapers that slope upward to the right come very near to 

 being uniform in length. Three are 25 mm. long; two are 24 mm. 

 long ; and only one is 21 mm. in length. Widths run about the same : 

 three are 17 mm. in width; two are 18 mm. in width; and the third 

 is 20 mm. in width. Thickness ranges from 4 mm. to 8 mm. Five are 

 excurvate trianguloid in outline and the other is roughly rectangular. 



The scrapers that slope upward and to the left are not quite as 

 uniform as to size. They range in length from 23 mm. to 29 mm., in 

 width from 15 mm. to 21 mm., and in thickness from 6 mm. to 9 mm. 



Triangular end scrapers (pi. 26, B, j-r). — Nine specimens. These 

 are excurvate edged triangles and are made from comparatively thin 

 flakes. They range in length from 22 mm. to 29 mm., in width from 



18 mm. to 25 mm., and in thickness from 4 mm. to 8 mm. Ventral sur- 

 faces are uniformly flat and the dorsal surfaces have retouching on all 

 three sides rising to a rounded keellike prominence. 



Slightly modified nodular end scrapers (pi. 27, A^ a-l). — End 

 scrapers of this type were made from pieces of jasper that still re- 

 tained part of the natural unmodified outer surface of the rock. The 

 shape of these flakes seemed immaterial to the one manufacturing end 

 scrapers of this type. Some of the flakes are roughly rectangular in 

 outline, others are triangular, and the rest are somewhat irregular 

 in shape. From the table of measurements in Appendix 4 one will 

 note that most of the flakes are about 6 mm. thick, but the range is from
