then wound upon itself; the outer coil thus formed (see Fig. 505)
being firmly fastened as it progressed to the one already made by
passing the splint wrapping of the wisp each time it was wound around
the latter through some strands of the contiguous inner coil, with the
aid of a bodkin. (See Fig. 506.) The bottom was rounded upward and the
sides were made by coiling the wisp higher and higher, first outward,
to produce the bulge of the vessel, then inward, to form the tapering
upper part and neck, into which, the two little twigs or splint
loop-eyes were firmly woven. (See again Fig. 503 _a_.)

These and especially kindred forms of basket-vessels were often quite
elaborately ornamented, either by the insertion at proper points of
dyed wrapping-splints, singly, in pairs, or in sets, or by the
alternate painting of pairs, sets, or series of stitches. Thus were
produced angular devices, like serrated bands, diagonal or zigzag
lines, chevrons, even terraces and frets. (See Figs. 507, 508, 509.)
There can be no doubt that these styles and ways of decoration were
developed, along with the weaving of baskets, simply by elaborating on
