STONE IMPLEMENTS 



[El II. ANN. IS 



Again, we observe tbat tlie percentage of failures — tlic turtlebacks 

 and other refuse of manufacture — decreases rapidl.N with the distance 

 from the source of supply of the raw material. Tliis may be illustrated 

 by a siip])(isiti()us case. In the vicinity of Wa.shinjxton w<^ liave a great 

 deposit of (juartzite bowlders. In liguie -18 the dotteil line may be 

 taken as roughly indicating the area yielding workable bowlders, and 

 the angular markings show the distribution of rejects of manufacture. 

 The successful blades and the finished tools jiroduced radiate much 

 more widely, but also diminish with distance from the source of sup- 

 ply, as indicated by the smaller strokes in figure 19, a generalized case 

 also. Favorite routes of travel would receive the fuller supply of these

objects, and dwelling and important hunting and fishing sites would 

 have hirgi^ supplies, as iiulicated by "village-sites'' in figure 20. Ou 

 the source of supply of the raw material, failures and unfinished imple- 

 ments or rejects exceed finished implements in numbers, but beyond 

 this the latter are almost wholly ])revaleiit. So-calhnl paleolithic 

 forms, the rejects of manufacture, are thus confined to certain areas — 

 the areas producing the raw material — and it is easy to see how, iu 

 various sections of the ccmntry before the true nature of these forms 

 was known, certain localities were thought to have been especially 

 lavored by the hypothetic paleolithic man. 



It would ap])ear from what has been said that the artificial distri- 

 bution of materials is limited by, and is indeed a modification of.
