moved (F), and the diagonals subse- 
quently added (G,H). It is only fair 
to state that I have not had the op- 
portunity of watching itsmanufacture. 
109. Hexagonal—The weft passes 
alternately over a strand of one and 
under a strand of another of two | 
series of warp elements crossed diag- 
onally. The initial key to the struc- 
ture of such a piece of basketry is a 
hexagon (fig. 39 A, B), which may 
be subsequently filled in with second- 
ary weft (C) and warp strands (D, 
E). (For illustrations see secs. 412— 
415.) There is a somewhat unusual 
duplicate hexagonal plait work (F) 
recorded from Surinam (GOK, pl. 
1x, fig. 12), and a triplicate one (G), 
apparently from our own colony on 
a knapsack (fig. 188). 
110. Pentagonal.—During the course Fis. 39.—Forms of weaving -hexag- 
of manufacture of the walls of certain i aca eae we a 
baskets (sees. 414, 422, 425), but never as an initial stage in basket 
manufacture, the mesh becomes a pentagon (fig. 39 H). It is formed 
by weft locking quadrilaterals formed of overlapping warp strands. 
111. Crossed quadrilateral—tThe initial key is a 
figure consisting of two series of strands crossed at 
right angles and held in position by two strands, also 
crossed at right angles, intersecting them diagonally 
(fig. 40 A). The weft passes alternately over two 
crossed and then under a single vertical warp 
strand (B). <A secondary weft or wefts may be 
subsequently interpolated (C). In the square open- 
work Makusi baskets (sec. 429) and certain Wapi- 
shana and Makusi knapsacks (sec. 451). 
112. Zwined—‘ The warp is not bent and the weft 
is made up of two or more elements, one of them 
passing behind each warp element (one or more) as 
the weaving progresses” (fig. 41 A). I have else- 
where (sec. 466) described this as a chain twist. In 
certain Rio Negro and other baskets (sec. 416).
