ably hafted much as are the scrapers of the Tehuelche of to-day 

 (fig. 30). 



A number of blades, flat on one face 

 and in cases handsomely chipped on 

 the other, are especially noteworthy and 

 may have served either as knives or as 

 scrapers. As a rule, one of the edges is 

 more decidedly curved outward than 

 the other and more carefully worked, as 

 seen in the illustrations (fig. 31). 



These wide blades (see pi. 14), which 

 appear to occur throughout the pampas 

 region and down to southern Patagonia 

 (Hatcher collection) , grade into narrower 

 plano-convex forms, the chipped face 

 being decidedly arched or ridged (fig. 

 32, a), and these pass into spikelike 

 forms (fig. 32, h), which may in cases 

 be rude or abortive projectile points. 

 However, all of these could have served 

 as scrapers while the more slender forms 

 could have been used as drills. 



It is a noteworthy fact that the entire 

 series of white quartzite artifacts, up- 

 ward of 400 in number, contains only a 

 dozen specimens chipped on both faces. 

 Only two of the dark-pebble artifacts 

 out of many hundreds of specimens are 

 thus chipped. The dissimilarities be- 

 tween the white quartzite and the coast- 

 pebble work referred to above may be 

 interpreted by some as indicating differ- 

 ences in the people concerned, or widely 

 separated periods of occupation, yet it 

 should not be forgotten that the form 

 and nature of the two kinds of raw ma- 

 terial are so unlike as to account for 

 somewhat marked dissimilarities, both 

 in processes and in forms made, even if 

 utilized by the same people at the same 

 period.

 scraper removed from the handle for

 The strong curve was imposed by the 

 curve of the glass fragment.
