REPORT OF NATIONAL MUSEUM, 1897. 



The following illustrations give a fair idea of these implements in 

 North America. They run the entire range of size, from the very large 



to the very small. Plate 25 has a fragment of 

 a large one of obsidian from Cordova, Mexico. 

 Fig. 87 is a leaf-shaped implement from Fol- 

 som, California, of symmetrical form, though 

 chipped in rough and rather large flakes. It 

 bears the evidence of use. It may have 

 been handled and used as a spear, or it may 

 have had a skin or other wrapping and been 

 used as a knife 

 or dagger. 

 Fig. 88 is from 

 St. George, 

 I 'tab. It is 

 of flinty chert, 

 and is a won- 

 derful piece of 

 art in flint 

 chipping. The 

 flakes run to 

 the center, and 

 so have r e - 

 d need the 

 thickness to 

 the minimum, 

 which is one- 

 eighth of an 

 inch. It is un- 

 fortnnat ely 

 broken in three 

 pieces, one of 

 which is lost. 

 Fig. 89 is a very thin specimen of fine- 

 grained flinty chert from Union County, 

 Kentucky, and is fig. 9 on Plate 28, Class A. 

 Fig. 90, from Northampton County, Vir- 

 ginia, is of quartzite and represents a type 

 prevalent along the Atlantic seaboard 

 from the Potomac to the James rivers. It 

 is found in abundance in the neighbor- 

 hood of Washington City (Plate 28, fig. 3). 

 Fig. 91 is of chalcedony, delicately 

 chipped, pointed at both ends, and is symmetrically lenticular (Plate 

 28, fig. 10). Fig. 92 is of obsidian, is similar to fig. 91, but thicker, and 

 its greatest width is nearer the base (Plate 28, fig. 8).
