added to the inner terraces. These
additions comfortably provided for a very large increase of population
after the first building of the pueblo, without changing its exterior
appearance.

In order to make clearer this order of growth in Mashongnavi, a series
of skeleton diagrams is added in Figs. 10, 11, and 12, giving the
outlines of the pueblo at various supposed periods in the course of its
enlargement. The larger plan of the village (Pl. XXVI) serves as a key
to these terrace outlines.

The first diagram illustrates the supposed original cluster of the east
court (Fig. 10), the lines of which can be traced on the larger plan,
and it includes the long, nearly straight line that marks the western
edge of the third story. This diagram shows also, in dotted lines, the
general plan that may have guided the first additions to the west. The
second diagram (Fig. 11) renders all the above material in full tint,
again indicating further additions by dotted lines, and so on. (Fig.
12.) The portions of a terrace, which face westward in the newer courts
of the pueblo, illustrated in Pl. XXIX, were probably built after the
western row, completing the inclosure, and were far enough advanced to
indicate definitely an inclosed court, upon which the dwelling rooms
faced.

SHUPAULOVI.

This village, by far the smallest pueblo of the Tusayan group,
illustrates a simple and direct use of the principle of the inclosed
court. The plan (Pl. XXX) shows that the outer walls are scarcely broken
by terraces, and nearly all the dwelling apartments open inwards upon
the inclosure, in this respect closely following the previously
described ancient type, although widely differing from it in the
irregular disposition of the rooms. (Pl. XXXI) A comparison with the
first of the series of diagrams illustrating the growth of Mashongnavi,
will show how similar the villages may have been at one stage, and how
suitable a nucleus for a large pueblo this village would prove did space
and character of the site permit. Most of the available summit of the
rocky knoll has already been covered, as will be seen from the
topographic sketch of the site (Fig. 13). The plan shows also that some
efforts at extension of the pueblo have been made, but the houses
outside of the main cluster have been abandoned, and are rapidly going
to ruin. Several small rooms occur on the outer faces of the rows, but
it can be
