ETid scrapers.—Upward of 250 of these ubiquitous little objects were found; they came to light wherever we dug on the site. They are like those from hundreds of other sites in the Plains region: planoconvex in cross section, prominently ridged dorsally or less commonly (ca. 8 percent) low and flattened, varying in outline from subtriangular to subelliptical or subovate, and with the edges re- touched all around (pi. 41).

The plane underside, representing the unmodified cleavage surface, is usually curved or "twisted" somewhat. Maximum thickness is near the wide end, which is always steeply sloped. Very commonly the edges are blunted. In size, they range from 17 to 97 mm. long, 14 to 40 mm. wide, and 5 to 15 mm. thick. In the longer specimens, width-length ratio is about 1, whereas.
