the posterior strings and drawn forward at every interspace to help 
form the basal chain, progressively manufactured from left to right, 
the simple construction of which is shown in the diagram (fig. 203). 
It is finally knotted. When the temporary separator, beater, or 
presser is next removed, the posterior layer of strings flies back to its 
original position, but is now under control of the raiser, which can 
also be moved in a vertical direction up or down, as may be desired 
(fig. 204). The permanent raiser in the remaining diagrams is rep- 
resented as a rod instead of a lath. 
471. To make a commencement, fix on your level and make your 
first row of single or double chain twist according to the pattern 
desired (fig. 206). The technique of the double chain twist is similar 
to that already described (sec. 466), and that of the single one similar 
to its upper or lower moiety. The only difference is that but one 
alternate warp, instead of each adjoining two, is locked every time

into a link of the twist (fig. 204 ct). Once this chain twist is com- 
pleted at the right extremity of the warp, it is knotted and cut. 
Now pull the raiser forward and, inserting the beater behind the 
posterior layer of warps, between it and the anterior layer, turn it on 
its broader axis (fig. 205 ts). This will now afford you the neces- 
sary space to insert your first single weft. But remember that while 
the chain-twist weft of this and other kinds of cotton hammock (see. 
466) are made with a short knob-headed spool (fig. 200), the plain, 
single wefts are here inserted on a long, thin, flat wooden shuttle 
(skelaribni, Wapishana) with concave ends, much after the style used 
in weaving an ordinary modern fish net (pl. 128 fs). The presser, 
beater, or temporary separator is next brought into requisition. 
This, after being slipped in between the two separated layers of (the 
front) warp, is made to beat and press upon the weft just manufac- 
tured, and this latter, beaten and pressed in turn downward against
