In the foreground of Pl. XXII may be seen a
number of examples of such work. Pl. XCI illustrates a group of corrals
at Oraibi whose walls are laid up without the use of mud mortar.
Where exceptionally large blocks of stone are available they have been
utilized in an upright position, and occur at greater or less intervals
along the thin walls of dry masonry. An example of this use was seen in
a garden wall on the west side of Walpi, where the stones had been set
on end in the yielding surface of a sandy slope among the foothills.
A similar arrangement, occurring close to the houses at Ojo Caliente,
is illustrated in Pl. XCII. Large, upright slabs of stone have been used
by the pueblo builders in many ways, sometimes incorporated into the
architecture of the houses, and again in detached positions at some
distance from the villages. Pls. XCIII and XCIV, drawn from the
photographs of Mr. W. H. Jackson, afford illustrations of this usage in
the ancient ruins of Montezuma Canyon. In the first of these cases the
stones were utilized, apparently, in house masonry. Among the ruins in
the valley of the San Juan and its tributaries, as described by Messrs.
W. H. Holmes and W. H. Jackson, varied arrangements of upright slabs of
stone are of frequent occurrence. The rows of stones are sometimes
arranged in squares, sometimes in circles, and occasionally are
incorporated into the walls of ordinary masonry, as in the example
illustrated. Isolated slabs are also met with among the ruins.
