Faceted angle hurins are not numerous and closely resemble a 

 number of the polyhedric burins. The majority of these occur on 

 broken chips or flakes of chert which were not trimmed. All are 

 single ended. 



Flat hurins occur that have the facet running down the cutting 

 edge of the flake that encroaches upon the bulbar face of the flake. 



PolyhedHc huj'iiis are made out of much thicker flakes of chert 

 whose parallel facets occur on one side of the working edge and are 

 opposed by a single facet. The workmanship is more delicate in that 

 more attention was given to the placement of the various chips to 

 create the burin facets. 



Cores are rough and shapeless and indicate where various flakes 

 have been struck olff at random. No prepared striking platforms are 

 visible, and the majority of the cores are of chert with rhyolite and 

 quartz in the minority. 



Racloirs, a definite type of scraper, have been identified from var- 

 ious Early Man sites within the reservoir area. The predominating 

 form is an end-bulb type (figs. 4, a, <?, // 5, d) retouched on one edge 

 only, forming either a straight or a convex side scraper. Some have 

 been retouched on adjoining edges which are at right angles to each 

 other. Usually these are on moderately thick flakes. Others occur on 

 thin flakes and display definite prepared striking platforms. Some 

 specimens have the bulb placed at one angle which classifies them as 

 oblique-bulb types. A number have resolved flaking instead of the 

 flat retouch, and the edges are convex rather than straight across. In 

 the double- sided group there are the same general characteristics 

 with an occasional variant known as the pointed end-bulb scraper. 



The oblique-huTb scraper can be one sided, pointed, or elliptical 

 and resembles similar groups in the end-bulb class. Sometimes these 

 are retouched on three sides, but usually this occurs only on two sides. 

 Whenever the angle is very acute (figs. 4, e; 5, e) , the racloir is classed 

 as one of the pointed types. In the right-angled type the position 

 of the bulb varies in its relation to the retouched edges but always 

 occurs at an angle on the flake. Usually the side-bulb type (fig. 5, h) 

 is fan shaped though there are some that have a straight scraper 

 edge ; these are generally made out of thicker flakes with larger bulbs. 



Scrapers^ in the intermediary class (pi. 18) , are much too ubiquitous 

 as horizon markers, for most types occur not only in Early Man sites 

 but continue through the Archaic stage and progress well into pottery- 

 making levels. They are worldwide in distribution, and the local 

 forms are reminiscent of corresponding implements from the typical 

 Mesolithic times of Europe but of a much later time differential. 

 Some forms occur only during the early cultural periods, while others 

 have become so well adapated that they continued to be manufactured
