y a plug of partially carbonized matted
coarse fibers. There is a narrow carbonized strip, slightly in from the
bowl end, which runs around the pipe; this appears to be the remnant of
a cord that had been tied around it. Since the pipe had been broken at
that end, it may have been repaired aboriginally with such a cord.

The smaller pipe (139564; pl. 12, _d_) barely tapers from the bowl end
to the mouth end. The ends of this pipe are conically drilled and they
interconnect; there is no drilled hole connecting the bowl with the
mouth end, as in the larger specimen. A partially carbonized plug of
matted coarse fibers also fills the mouth end of the smaller pipe.

Although simple tubular stone pipes occur sporadically in the
archaeology of the Southwest, they are encountered frequently in central
and northern Baja California. Stone tubes or pipes, called _chacuacos_,
are often mentioned in Spanish sources as part of the shaman's
paraphernalia in this Yuman-speaking area of the peninsula (Venegas,
1944, I:93, 95; Clavigero, 1937, p. 115).

In the known areas of archaeological occurrence these pipes appear in
two distinct sizes, even as they are represented in the two Bahia de Los
Angeles specimens. There is the long type, measuring more than 15 cm.,
of which several specimens have been found in Baja California, at Bahia
de Los Angeles, at a site near the Rosario Mission in the northwest, and
throughout the central part of the peninsula (Massey, field notes). This
type has also been noted from Ortiz, Sonora (Di Peso, 1957, p. 288), and
in a late prehistoric or historic level at Ventana Cave (Haury, 1950,
p. 331).

The shorter type, usually about 7 cm. in length, is known to occur in
the general central region around Mulege (Massey, MS 2) and at Bahia de
Los Angeles. In the Southwest, the smaller type has been reported from
Chiricahua-Amargosa II levels at Ventana Cave (Haury, 1950, p. 329); La
Candelaria Cave, Coahuila (Aveleyra _et_ _al._, 1956, pp. 174-175); San
Cayetano Ruin (Di Peso, 1956, pp. 423-430); and from a series of sites,
particularly in the Mogollon area (Martin _et_ _al._, 1952, pp. 112-113,
fig. 44).

Similar pipes have also been found in the western Great Basin at
Lovelock Cave (Loud and Harrington, 1929, pl. 52) on the old shoreline
of Humboldt Lake (ibid., pl. 65), and at Humboldt Cave (Heizer and
Krieger, 1956, p. 71; pl. 31, _e_, _f_).

Ethnographically, pipes of straight tubular shape are characte
