IMPLEMENTS AND WEAPONS OP THE STONE AGE. 127 



in England. In one of the mounds of Ohio, Squier 

 and Davis discovered an immense number of rudely- 

 shaped flint discs placed on end. They are on the 

 average six inches in length, and weigh about two 

 pounds each. They are evidently unfinished imple- 

 ments, and Rau regards this as a depot or magazine 

 from which supplies of flint could be obtained as re- 

 quired, and where the material could be kept damp, 

 so that it might be the more easily chipped. 



A somewhat similar place is described by Leidy in 

 a recent report on the geology of the Western Terri- 

 tories. It is at the base of the Uintah Hills, in "Wyom- 

 ing, where vast quantities of jasper, agate, and other 

 stones suitable for implements, have been swept down 

 upon the plain. Immense numbers of these have 

 been chipped and broken into angular fragments, 

 whether by art or nature does not seem evident ; but 

 from the number of arrow-heads and other definitely- 

 formed objects, it is evident that the place was for 

 ages resorted to as a quarry and manufactory. Nor 

 need we wonder at this when we consider the dense 

 agricultural population evidenced by the mounds and 

 earthworks of the old Alleghans in all the alluvial 

 plains of the West, and that thousands of industrious 

 flint- chipper s and migratory traders must have been 

 constantly employed in working the agates and jas- 

 pers of the hills, and transporting them to the towns 

 and villages of the plains, where they are still found 

 in great numbers.
