In the Tusayan house illustrated in Pl. LXXXIV, the construction of
which was observed at Oraibi, the interstices between the large stones
that formed the body of the wall, containing but small quantities of mud
mortar, were filled in or plugged with small fragments of stone, which,
after being partly embedded in the mud of the joint, were driven in with
unhafted stone hammers, producing a fairly even face of masonry,
afterward gone over with mud plastering of the consistency of modeling
clay, applied a handful at a time. Piled up on the ground near the new
house at convenient points for the builders may be seen examples of the
larger wall stones, indicating the marked tabular character of the
pueblo masons' material. The narrow edges of similar stones are visible
in the unplastered portions of the house wall, which also illustrates
the relative proportion of chinking stones. This latter, however, is a
variable feature. Pl. XV affords a clear illustration of the proportion
of these small stones in the old masonry of Payupki; while in Pl. XI,
illustrating a portion of the outer wall of the Fire House, the tablets
are fewer in number and thinner, their use predominating in the
horizontal joints, as in the best of the old examples, but not to the
same extent. Fig. 35 illustrates the inner face of an unplastered wall
of a small house at Ojo Caliente, in which the modern method of using
the chinking stones is shown. This example bears a strong resemblance to
the Payupki masonry illustrated in Pl. XV in the irregularity with which
the chinking stones are distributed in the joints of the wall. The same
room affords an illustration of a cellar-like feature having the
appearance of an intentional excavation to attain a depth for this room
corresponding to the adjoining floor level, but this effect is due
simply to a clever adaptation of the house wall to an existing ledge of
sandstone. The latter has had scarcely any artificial treatment beyond
the partial smoothing of the rock in a few places and the cutting out of
a small niche from the rocky wall. This niche occupies about the same
position in this room that it does in the ordinary pueblo house. It is
