A small rhyolite ax (fig. 14, d), displaying an even outline as tlie 

 result of extra fine retouching, has a rounded blade which slopes 

 upward along convex sides to terminate in a somewhat dulled pointed 

 butt. Flake size is fairly large and uniform due to the percussion 

 techniques used to blank out the implement, while pressure chipping 

 was used chiefly along the edges. The cutting edge is more char- 

 acteristic of an adz tlian an ax. This ax measures 121 mm. in length, 

 60 mm. in maximum width — wliich is slightly off center and closer 

 to the cutting surface — and 25 mm. in thickness. 



There is another chert ax in the collection that has a squarish cut- 

 ting edge rather than the usual rounded edge (fig. 14, a). It was 

 initially roughed into shape by percussion chipping and later re- 

 touched on sides and edges, giving the object a finished look. In 

 overall size this is the smallest of the axes in the collection. It might 

 be termed a chopper, for it measures 98 mm. in length, 63 mm. in 

 width, and 22 mm. in thickness. 



Within the same size range is a quartz specimen, 113 mm. long, 57 

 mm. wide, and 27 mm. thick. The same techniques were expended 

 upon this tool resulting in an ovate blade with a pointed butt and 

 rounded cutting surface. 



A number of smaller specimens, while not of the true core type, 

 were manufactured from rather large thick chert flakes. In some 

 instances the original surfaces of the stone are still visible. Tech- 

 niques of chipping, as well as general form, resemble the larger speci- 

 mens and differ only in that the chipping, as a rule, is better con- 

 trolled, resulting in an even outline and cutting edge. 



The larger of these smaller specimens must have measured approx- 

 imately 110 mm. in length before its butt was broken off. At the 

 present time only 78 mm. of its length is intact. Width is 44 mm., 

 and thickness is 14 mm. The sides are straight and converge to a 

 bluntly pointed butt, the tool resembling an equilateral triangle in 

 general outline, while the cutting edge, 16 mm. in extent, is formed 

 by rounding off the base of the triangular body. 



Another specimen, with convex sides, rounded blade, and dully 

 pointed tip, has one surface that has been formed by parallel trans- 

 verse flakes which carry completely across tlie specimen's surface, 

 while those on the reverse side do not extend quite so far. The 

 exterior margin of one face was retouched while in the margin on the 

 obverse face the chipping is much larger and irregular, and no re- 

 touching was used to refine the edge. This particular specimen 

 measures 105 mm. in length, 40 mm. in width, and 15 mm. in maximum 

 thickness. It is covered with a thin veneer of patination. 



Another specimen resembles the one just described but is much better 

 made. It is heavily patinated, which can be detected where part of 

 the butt is missing. The transverse flaking used carries to a midline
