width is therefore 0.56 m.--22
in.,--as proven by actual measurement. The idea is therefore
suggested--very naturally--that the entire western wing of the building
_A_ was originally a double house,[119] terraced both towards the east
and the west. In sketching the cross-sections, I have taken due notice
of this very probable, if not positive, fact.

The double wall _m N_ shows no trace of lateral passages. It therefore
divides the whole structure from _H_ to _N_ into two longitudinal
sections. The western one, from _o_ to _p_, consisted of but one row of
5 rooms; from _p_ to _N_ it had two rows of 16 chambers each. The
ground slopes still further to the S. and S.W. outside of the
trapezoidal enclosures, _I I_, and is covered with _debris_; so that I
presume that, from _ll_ to _N_, there was an additional row of 3 rooms
on the outside. The entire division was at one time very completely
razed to the ground, so that its owners never attempted to rebuild it
after the original plan.

The western division was also badly damaged in its southern half, but
the damage was subsequently repaired with the aid of material and
mechanical arts postdating the Spanish conquest of New Mexico. Pl. V.,
Fig. 3, gives a view of the western end, along the line _h h_.

I would recall here the fact already noticed, that the northern part of
building _B_ is also mended in places with adobes of the same make as
those used in repairing the western wing of _A_, and that, while the
squared beams are wanting, the stone-work there in places appears also
of a more recent date. The suggestion may therefore not be uncalled for,
that the same destroying power which spent its main force on _A_,
distinct from the general decay, and moving in a direction from S.W. to
N. E., reflected or glanced off upon the northern portions of _B_. This
question will, however, be discussed hereafter.

The annexes _I I_ are trapezoidal enclosures of stone-work as high as a
man's breast, and respectively of the sizes indicated on the
ground-plan. The northern one is divided lengthwise into two
compartments; the southern is open to the south. Both appear to be new
and unfinished. From the centre of the last one protrude two
well-squared heavy timbers. These timbers are in a singularly unfit
position; they cannot be accounted for, and convey the impression that
they were carried hither from some other totally different construction.
They look almost forlorn. Whence they ca
