and a number of the other types were pro])ably made in level I times. 

 Side scrapers are rather abundant ; there are 'j'j of planoconvex type 

 (pi. 24, fig. I, a). (The distinction between a planoconvex flake knife 

 and the same type of scraper is in the edge. If the edge is thin and 

 sharp the artifact is called a knife; if abrupt and blunt, a scraper. 

 Naturally the choice in some cases must be arbitrary, but in general 

 the types are distinct.) There are 39 side scrapers (NE) retouched 

 on both faces (pi. 24, fig. \, e'). A number of both of these types are 

 probably from level I. Many are broken, and some of the large double- 

 faced scrapers may have served as chipped celts. Stone drills and 

 gravers include 26 artifacts. Of these, 9 are triangular and retouched 

 on both faces (pi. 24, fig. i, g) ; 14 are unifaced gravers, in some cases 

 suspiciously like those from level I (compare pis. 24. fig. i. ;" and 25, 

 fig. 1,0! the same is also true of three flakes with tiny retouched 

 points (pi. 24, fig. I, z"). In addition to the above a large number of 

 unclassifiable chipped fragments, flakes and cores come from level III. 

 The material from level II is limited. There are 73 chipped points, 

 of which 29 are ovoid side scrapers (NE). The most abundant and 

 typical projectile points from this level are stemmed (SC), of these, 

 17 have straight bases and barbs (SCb2) and 10 are without barbs 

 (SCa2) (pi. 24, fig. 2, c, /. ) The SCb2 points roughly average 3.5 cm 

 in length and comprise the most distinctive artifact type from this 

 horizon. There are 17 of the leaf-shaped type (NA), 10 of NAb2 and 

 7 of NAbi. A number of these leaf -shaped points are indubitably of 

 level I type and were probably carried up by the level II people. From 

 level II come 25 flake knives of medium to small size (pi. 24, fig. 2. n). 

 The majority are mere flakes with retouched edges, and some were 

 probably carried in from level I. There are 27 planoconvex end 

 scrapers, of which 14 are more or less re-touched on the upper surface 

 and 13 are without any retouching on the top (pi. 24, fig. 2, /, 111). All 

 are rather crudely worked, and there is a general similarity to the 

 level I type, although the ])roportion of retouched to unretouched is 

 higher. There are 60 small to medium-sized planoconvex, side scrapers 

 (pi. 24, fig. 2, /). A few of these are of the neat, round, level I type 

 with two plane surfaces and an abrujjt edge. Some 29 side scrapers 

 (NE) retouched on both sides come from this level (pi. 24, fig. 2, k). 

 Many of these are irregular in shape. Several side scrapers are made 

 of clear white and of rose quartz (pi. 24, fig. 2, / center). There are 

 19 stone drills and gravers, of which 9 are T-shaped, 2 are triangular 

 (retouched on both sides), 2 are flakes with small points, and 6 are 

 planoconvex gravers (pi. 24, fig. 2, c. J, g). In addition to the above,
