Description of Objects 
The textile bags (pl. 62, ac) are twilled-woven, seamless sacks 
originally about 5 inches long. How their bottoms were formed 
can not be determined from the badly decayed specimens, but the 
bodies seem to have been cylindrical with unconstricted mouths. The 
fabric at the apertures was turned in and sewed down to form tun- 
nels for the heavy, round draw strings, which were neatly braided 
of many strands. The material of the bags is apparently cotton,

the warp in natural color, the weft dyed dark to bring out the com- 
plex twilled pattern. 
Two of the bags are so much rotted that the details of the weave 
cannot be ascertained; a part of the third (pl. 62, @) is in sufficiently 
good condition to allow of the threads being counted. The following 
twill formula was determined for a series of eight or nine rows: 
plus 2, minus 1, plus 3, minus 2, plus 2, minus 2, plus 2, minus 2, 
plus 3, minus 1, plus 2, minus 5, and repeat (see fig. 67). The order 
of pluses and minuses is not changed from row to row, but the twill 
is “set over” to produce the diagonal effect in the following manner: 
beginning with the row lettered A, it will be seen that there are two 
plus 3’s, one (which we will call a) coming between minus 1 and 
minus 2, the other (called 7) coming between minus 2 and minus 1. 
In the second row (#) the plus 3 lettered x is set directly below the
