The objects with both ends grooved tend to be larger and the compression of the ends flattened them to almost cuboidal in outline.
Sizes are rather uniform, between 3.8 and 6.8 cm. in greatest dimension. The average weight of an available sample is 77 grams. The lateral grooving of these objects apparently was achieved in the ways described for Melon-shaped (p.34). A count of the number of lateral grooves on 217 of this variety (Table 12) shows 91.7 percent with four grooves, 6 percent with three, 1.84 percent with five and one object with two grooves The end grooves seem to have been made by counterpressure of thumb and opposed finger of one hand; the latter often seems to have been the flexed index finger, producing end grooves that are at right angles to each other Nearly one-fourth of the objects have only dimples of thumb or finger ends with similar four dimpling of the sides, these objects are near cuboidal
or die-shaped with a shallow indentation on each face (Fig. 6p) .
The melon-shaped objects with one end groove range in size from
3.4	to 5.4 cm. in greatest dimension. The average weight of a sample is 70 grams. Since they apparently were shaped by compressing a ball of sand-clay between the thumb and fingers of one hand and pushing it against the thumb or finger of the other hand, the shape tends to be crudely conical or pyramidal (Fig. 6o,o'). Three lateral grooves, instead of four, were favored in this variety (Table 12). A count of grooves on 404 objects of this variety, nearly half of the total from the site, shows 81.93 percent with 3 lateral grooves, 13.12 with four, 4.21 percent with two and 0.74 with one. Many of these with one end and three lateral grooves show diagonal placement of the laterals (Fig. 6o,o'), possibly resultant from the semiflexed position of the thumb and first two fingers to form the grooves. One object with three lateral grooves has crossed grooves at one end.
