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 model 
ing 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 exam- 
ples 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 illus- 
trates the relative proportion of chinking stones. This latter, however, 
is a variable feature. Pl. xv affords a clear illustration of the propor- 
tion 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 hori- 
zontal joints, as in the best of the old examples, but not to the same 
extent. Fig. 55 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
