e of symbols, seven in number, were
employed to indicate the amount and distribution of the debris. The
plans, as published, indicate the relative amounts of debris as seen
upon the ground. Probable lines of wall are shown on the plan by dotted
lines drawn through the dots which indicate debris. With this exception,
the plans show the ruins as they actually are. Standing walls, as a
rule, are drawn in solid black; their heights appear on the field
sheets, but could not be shown upon the published plans without
confusing the drawing. The contour lines represent an interval of 5
feet; the few cases in which the secondary or negative contours are used
will not produce confusion, as their altitude is always given in
figures.

PLANS AND DESCRIPTIONS OF RUINS.

The ruins described in this chapter comprise but a few of those found
within the province of Tusayan. These were surveyed and recorded on
account of their close traditional connection with the present villages,
and for the sake of the light that they might throw upon the relation of
the modern pueblos to the innumerable stone buildings of unknown date so
widely distributed over the southwestern plateau country. Such
traditional connection with the present peoples could probably be
established for many more of the ruins of this country by investigations
similar to those conducted by Mr. Stephen in the Tusayan group; but this
phase of the subject was not included in our work. In the search for
purely architectural evidence among these ruins it must be confessed
that the data have proved disappointingly meager. No trace of the
numerous constructive details that interest the student of pueblo
architecture in the modern villages can be seen in the low mounds of
broken down masonry that remain in most of the ancient villages of
Tusayan. But little masonry remains standing in even the best preserved
of these ruins, and villages known to have been occupied within two
centuries are not distinguishable from the remains to which distinct
tradition (save that they were in the same condition when the first
people of the narrators' gens came to this region) no longer clings.
Though but little architectural information is to be derived from these
ruins beyond such as is conveyed by the condition and character of the
masonry and the general distribution of the plan, the plans and relation
to the topography are recorded as forming, in connection with the
traditions, a more complete
