twilled twining. As in the plain twining the weft threads are 

 twined but include two warp threads instead of one. The next pair 

 of weft threads entwines the second of the first warp pair and an- 

 other, or the third warp strand. The first pair of weft threads 

 would then encircle warp threads 1 and 2, 3 and 4, 5 and 6. This 

 same pair would cross each other between warp threads 2 and 3 and 

 4 and 5. The second pair of weft threads would encircle warp 

 threads 2 and 3, 4 and 5, and 6 and 7. They would cross each other 

 between warp threads 1 and 2, 3 and 4, and 5 and 6. If the weft 

 threads were then pulled tightly together, the first pair would pull 

 one set of warp threads together while the next set of weft threads 

 would pull another set of warp threads together. This would pro- 

 duce a zigzag mesh. 



Chart XII has a number of sherds that carry impressions that are 

 difficult to decipher. Sherd No. 16 appears to have two such weaves. 

 One of these appears to be a plain twined weave with a close weft 

 and a wide invisible warp. Sherds Nos. 18 and 26 also bear this 

 weave. The second type on Sherd No. 16 appears to be a variation 

 of the twilled twine weave with a hidden warp and the weft pulled 

 close together (pi. 80, b). This second type also appears on Sherds 

 Nos. 17, 22, 26, and 32. 



The fabric impressions on the body sherds are also predominantly 

 the plain twine with a rectangular mesh. Two of the body sherds 

 can be definitely identified as having twilled twining, while Sherd 

 No. 14 appears to be of the same type as the twilled-twine variation 

 on Sherd No. 16 (Chart XII). 



As can be seen from the figure illustrating the large salt-pan 

 sherd, the shape of these vessels at this site appears to have been 

 that of a large shallow platter. It is 22 inches in diameter and 

 about 6 inches deep. The rims have a slight curve and are much 

 thicker at the lip than at the rim or body portion (fig. 74). The 

 sherds described in Chart XI have a lip thickness which ranges from 

 0.7 cm to 3 cm, with 80 percent falling between 1.5 cm and 2.5 cm. 

 Those salt pans on which the fabric impression was placed a short 

 distance below the lip (Sherd No. 1, pi. 148, a) have a lip thickness 

 which ranges from 0.4 cm to 1.6 cm, with 82 percent having a width 

 of 0.8 cm to 1.5 cm. In contrast to the difference in lip dimensions, 

 the rim and body thicknesses of the two salt-pan groups are more 

 nearly the same. The first group ranges from 0.5 cm to 1.4 cm, with 

 82 percent falling between 0.7 cm and 1.1 cm. The second group of 

 salt pans ranges from 0.5 cm to 1.3 cm, with almost 28 percent having 

 a width of only 0.5 cm and with almost 90 percent being less than 

 1.1 cm in thickness. 



The estimated lip diameters for some of the sherds described on 

 Chart XI are: No. 1, 22 inches; No. 7, 18 inches; No. 22, 20 inches;
