Shaft-smoother
One shaft-smoother was found, with lengthwise grooves on both faces. The lower is very shallow; the upper is clearly formed, and measures ³/₁₆-⁴/₁₆ inches wide and ⅛ inch deep ([see Fig. 47]).
Pigment Stones ([Fig. 48])
Eleven objects are classified as pigment stones. Four are lumps of red ochre. There is no proof that they were used for paint, but as Coon (1950) has noted, the use of some sort of paint is practically universal among primitive people. The largest weighs about three ounces, the smallest about two. Three pieces of yellow ochre were found. One is a great lump weighing about two pounds. The other two are flat ground palettes, slightly irregular, one about 1 × 2, the other 3 × 4 inches and both about ¼ inch thick.
