novi] DOMESTIC IMPLEMENTS AND REQUISITES 809 
plaited mats allow of a classification into more or less well-defined 
groups: 
(a) No special edging distinct from the foundation (sec. 395), 
(6) A special edging on two opposite sides only (sec, 396), 
(c) A special edging around the whole circumference (sec, 397). 
(7) Roll-up mats (sec. 398). 
(e) Mat satchels (sec. 899). 
$95. In the first there is no special edging distinct from the founda. 
tion. The plait may be of the somewhat rare one-over-and-under-one 
type (pl.89B),as in the square mats used on the Aiary River for 
covering pots, etc. (KG, 1, 224), and in such a case is a checker 
pattern. Where, however, as is far more usually the case, the plait 
is of the one-over-and-under-three type (pl. 90 A), the resulting 
pattern is one of concentrics, grilles, either separate or combined, 
dog’s eyes, Greek keys, ete. |1T am taking no account here of the 
one-over-and-under-two plaited knapsack covers, which are only 
Ma, 98.—Dingram showing the manufacture of mat io plate 90 B, 
used as mats secondarily.| Their mode of construction will depend 
upon the shape, whether a parallelogram or a square. In the former 
case this is identical with what I have already described for the 
Pomeroon Carib fan with the split-pencil handle (sec, 875), In- 
deed, it is almost a question whether this fan is not in reality a 
specialized mat. So, again, with the latter, this is identical with 
that of the Akawai fan (sec. 876), the same object for which all the 
smaller true mats may be employed. Made from itiriti by Akawai, 
Carib, Patamona, Arekuna, Warrau. 
$96. In the second group will fall all those mats with a special 
edging only on two opposite sides (pl. 90 B). ‘This is composed of 
two conical bundles, placed end to end, formed by the extremities 
of the two sets of plait strands, each bundle not only progressively 
increasing in bulle with every plait strand added, but actually being 
looped up with it during the process. This arrangement can be 
observed in the Astrocaryum mats of the Wapishana (fig. 98). In 
the smaller itiriti plaited mats of the Makusi (pl. 91 A) the bundles,
