402. For descriptive purposes I am proposing the following classi- 
fication of the multifarious articles known as trays: 
A. Rectangular: ; 
(a) With straight vertical rims, edgings, or lamin plaited (i) 
independently of any rail or weft (sec. 403) ; (ii) after being 
wound over.a supporting rod (weft) or rail (sec. 404) ; (111) 
inclosing a series of rails (wefts) (sec. 405). 
. (b) With concave outward sloping rims (sec. 406). 
(c) Hanging trays (sec. 407). 
B. Circular: 
(a) Edging formed of (i) its own strands specially twisted and 
plaited (sec. 408) ; (ii) a capped lining (sec. 409); (a1) 
a series of rails (sec. 410). 
(b) Hanging trays (sec. 411). 
403. Rectangular trays with straight vertical rims are all plaited 
in closework, and are mainly employed for collecting the cassava 
flour after passing through the sifter; but, of course, they can be and 
are put to other uses. As already mentioned (sec. 393), the plait for 
the foundation is ordinarily the one-over-and-under-three (twilled) 
type (sec. 108), but with the Akawai and Patamona it may be seen 
worked on a one-over-and-under-two model (pl. 97 A, B). Once the 
foundation is completed, the procedure is continued along one or 
other of the following lines: In the first series (pl. 96 A), the pro- 
jecting strands (itiriti) are plaited in such a manner as to form a 
vertical laminated edging—i. e., at right angles to the foundation 
and of equal depth above and below (fig. 103 A). The upper and 
lower borders of this edging may be subsequently strengthened with 
cane strip and vine (pl. 96 B; fig. 103 B). Wapishana, Makusi. 
404. The second series will contain the Akawai forms (fig. 103 C), 
where the projecting strands form a similar laminated edging after 
being wound over and under a supporting rail (or weft). Taking 
two projecting strands at a time, these are together rolled once over 
the rail (7) and emerge from beneath it. They are next “broken” 
(i. e., sharply bent upward) and passed, respectively, over and under 
the two next emergent pairs, to be finally bent downward and plaited, 
respectively, under, over, and again under the next three pairs, be- 
hind the last one of which they are cut. The outcome of this tech- 
nique is that the two margins of the strands, where broken, form two 
sharp ridges, which, in practice, are drawn very close together. 
405. In a third series may be placed trays where the edging is 
composed of a series of rails (wefts) plaited together, by means of 
the projecting strands, to form the vertical lamina (pl. 97 A). As
