mly, and, when the surface is unbroken, answers fairly
well as a watershed. A slight slope or fall is given to the roof. This
roof subserves every purpose of a front yard to the rooms that open upon
it, and seems to be used exactly like the ground itself. Sheepskins are
stretched and pegged out upon it for tanning or drying, and the
characteristic Zuni dome-shaped oven is frequently built upon it. In
Zuni generally upper rooms are provided only with a mud floor, although
occasionally the method of paving with large thin slabs of stone is
adopted. These are often somewhat irregular in form, the object being to
have them as large as possible, so that considerable ingenuity is often
displayed in selecting the pieces and in joining the irregular edges.
This arrangement, similar to that of the kiva floors of Tusayan, is
occasionally met with in the kivas.

In making excavations at Kin-tiel, the floor of the ground room in which
the circular door illustrated in Pl. C, was found was paved with large,
irregular fragments of stone, the thickness of which did not average
more than an inch. Its floor, whose paving was all in place, was strewn
with broken, irregular fragments similar in character, which must have
been used as the flooring of an upper chamber.

WALL COPINGS AND ROOF DRAINS.

In the construction of the typical pueblo house the walls are carried up
to the height of the roof surface, and are then capped with a continuous
protecting coping of thin flat stones, laid in close contact, their
outer edges flush with the face of the wall. This arrangement is still
the prevailing one at Tusayan, though there is an occasional example of
the projecting coping that practically forms a cornice. This latter is
the more usual form at Zuni, though in the farming pueblos of Cibola it
does not occur with any greater frequency than at Tusayan. The flush
coping is in Tusayan made of the thinnest and most uniform specimens of
building stone available, but these are not nearly so well adapted to
the purpose as those found in the vicinity of Zuni.

Here the projecting stones are of singularly regular and symmetrical
form, and receive very little artificial treatment. Their extreme
thinness makes it easy to trim off the projecting corners and angles,
reducing them to such a form that they can be laid in close contact.
Thus laid they furnish an admirable protection against the destructive
action of the violent rains. The stones are usually
