fact is 95 mm long by 32 mm wide. The rounded end suggests the 

 point of the blade, the other flattened end the butt. 



The triangular type (NBa) is only slightly more numerous. There 

 are only two knives of this form, one of which is illustrated (pi. 7, 

 fig. 2, /). The latter is 105 mm long, 43 mm wide, and 11 mm thick 

 and is rather roughly retouched. It is heavily incrusted with lime, as 

 the illustration indicates. The second specimen is similar to the above 

 but somewhat smaller (65 by 38 by 7 mm). 



Diamond-shaped knives (NC) are more common, six coming from 

 house I. A typical specimen of jasper is figured (pi. 7, fig. 2, d). All 

 these specimens are thin, and, with one exception, are biconvex. The 

 one exception has one flat surface. The material of all is jasper, and 

 they range in length from 114 to 66 mm and in width from 45 to 

 2/ mm. One other specimen (pi. 7, fig. 2, b) is of this general type 

 but has one end slightly rounded. Perhaps this was the hafted end. 



The sixth and last type (NCa), that is, the diamond-shaped and 

 beveled form, is poorly represented in house i. One rather small 

 specimen of yellow jasper has four beveled edges. Its dimensions are 

 62 by 38 by 6 mm. An unusual specimen with two notches above the 

 point is likewise beveled and suggests this type (pi. 7, fig. 2, e). How- 

 ever, the larger part of the blade, on the other side of the notches from 

 the complete point, is broken and it is uncertain what the original shape 

 of the entire piece may have been. This is the only notched knife blade 

 so far encountered in our excavation work. 



Many pieces of heavy chipped stone work were found in house i. 

 In all, 80 artifacts roughly classified as axes, hoes, and picks were 

 recovered. No polished stone celts or grooved axes were found. 

 Practically all of these larger chipped stone artifacts were of yellow or 

 brown jasper and were probably made from local material. The 

 following classification according to function is open to some question 

 but seems justified by the nature of the objects. 



Forty-nine of these larger chipped artifacts appear to have been 

 used as axes. These are of two t3'pes, a triangular form with a broad 

 blade (35) and a more oval form with a less distinct blade (14). That 

 they were used as axes is indicated by the battered and often retouched 

 edge as well as by their form. Seven specimens have slight notches on 

 one or both sides, suggesting that they were hafted. It is extremely 

 probable that the majority had handles of wood. So mounted, they 

 would make excellent chopping tools. Both the triangular (pi. 17, 

 fig. 2, k) and the oval (pi. 17, fig. 2, ;, /) axes are carefully worked 

 and, unless battered from use, have keen cutting edges. Certain of the 

 oval specimens in particular are beautifully retouched and of a perfect
