the wiirps. In l)am])oo ])asketr3^ of eastern Asia these crossed warps 

 are also interlaced or held tog-ether by a horizontal strip of bamboo 

 passing in and out in ordinary weaving. In such examples the inter- 

 stices are triangular, but in the twined example here described the 

 weaving passes across l)etween the points where the warps intersect

each other, leaving hexagonal interstices. (See tig, 18 and Plate 166,) 

 This combination of plain twined weft and crossed warp has not a wide 

 distribution in America, but examples are to be seen in southeastern 

 Alaska and among relics found in Peruvian graves. 



2. Dtagoiial tunned inenving. — In diagonal twined weaving the twist- 

 ing of the weft filaments is precisely the 

 same as in plain twaned weaving. The difier- 

 ence of the texture is caused b}' the manner 

 in which the weft crosses the warps. This 

 style aboinids among the Ute Indians and 

 the Apache, who dip the bottles made in 

 this fashion into pitch and thus produce a 

 water-tight vessel, the open meshes receiv- 

 ing the pitch more freely. The technic of 

 the diagonal weaving consists in passing 

 over two or more warp elements at each 

 turn, just as in weaving with a single ele- 

 ment. But the warp of the diagonal twined 

 weaving never passes over or under more than one weft as it does in 

 twilled weaving. There must be an odd number of warps, for in the 

 next round the same pairs are not included in the half turns. The 

 ridges on the outside, therefore, are not vertical as in plain weaving, 

 but pass diagonally over the surface, hence the name. (See Plate 20, 

 and figs. 19 and 20.)
