omplished very evenly, producing no distortion of the flat surface.
Twining was done with the pitch up-to-the-right. The weft was also of
2-ply agave (?) cord.

The one peculiar feature of this twined band is the form of the selvage,
which gives the appearance of a sewing running-stitch along the heavy
outer cords.

It is extremely unlikely that this was a sling or belt. The band seems
too rigid to have been used for either of these two purposes, and slings
are not recorded historically from Baja California.

The only similar specimen know in the archaeology of the peninsula is a
fragment of a tump band from the upper or historic level of Metate Cave
near Comondu.[6] This fragment is identical with the tump band from
Bahia de Los Angeles in weave, selvage, and cordage. Even the count is
similar: 9 warps and 15 wefts per inch for the Bahia de Los Angeles
example, and 10 by 22 for the Metate Cave specimen. Either of these is
much coarser than Basketmaker bands, like those from Segi Canyon with
their 24 warps and wefts per inch (Guernsey, 1931, p. 9).

The tump band was used for portage with carrying nets among the historic
Indians of central Baja California (see "Carrying Nets"). The modern
Kiliwa of the north supported nets on the back by a band which passed
across the forehead. At the forehead this band consisted of 20 "parallel
cords" (Meigs, 1939, p. 38; twined or simple cords are not stipulated).
Woven packstraps were used by all southern California Indians (Drucker,
1937, p. 21). Babies and general burdens were carried in nets supported
by the forehead tumpline in the central and northern areas of the
peninsula (Clavigero, 1937, p. 106).

_Cotton Cloth_

Since woven cotton (_Gossypium_ sp.) was unknown in aboriginal Baja
California at the time of European contact, its provenience must be
beyond the peninsula. Presumably this specimen is a piece of
pre-Columbian trade goods from the mainland of Mexico, and so belongs in
the cultural inventory of the cotton-weaving cultures of the Oasis Area.

The weave of this fragment (139537) is Plain (over-one-under-one) (pl.
17, _c_). The piece, which measures 25.5 cm. long (warp) by 30 cm.
(weft), consists of one loomstring end and neither selvage. The warp is
white cotton cord, 1 mm. in diameter, in a loosely twisted 2-ply
Z-twist. The weft of the same material has a diameter o
