lustrate their extent and shape. Pl. I., Fig. 5.

The distances are not very correctly given, and the shape of _F_ is
slightly exaggerated in irregularity.

_A_ and _B_ being the respective large buildings, _C_ the church, _D_
the great gate of the circumvallation; _E_ is a stone or rubble wall of
undeterminable length running along the foot of the mesilla in a slight
curve till near the "wash-out" sallying from the gate, and _F_ is an
irregular lozenge, or trapeze, enclosed by a heavy low stone or rubble
wall which might in some places be called an embankment. The corner _l_
is 50 m.--165 ft.--from the border of the creek-bottom, which there is
cut off abruptly from 1 m. to 3 m.--3 ft. 3 in. to 10 ft.,--presenting a
section of red clay and gravel with pottery fragments. The line _l r m_
runs W.N.W. to E.S.E., and is 138 m.--452 ft.--long; the line _m s n_
measures 121 m.--398 ft.,--_n o p_ 146 m.--480 ft., and _p l_ 100
m.--330 ft. From _r_ to _s_ an embankment of earth and stone runs almost
in a circle, and the whole triangle _r m s_ forms a slightly elevated
platform, in the centre of which is a pond (_estanque_) _t_, which, even
at the present time, is filled with water. Viewed through the gate from
above, this pond appears, with a part of the enclosure, as seen in Pl.
IX. Several gullies (_barrancas_) have cut through the western and
southern parts of the enclosure.

This enclosed area, now covered with tufts of grama, occasional
cactuses, knolls and scattered drift and pottery, was according to Sr.
Ruiz, the former _huerto del pueblo_; that is, the fields of the
inhabitants of the pueblo, where they planted and raised Indian corn,
beans, calabashes, squash, and, after the advent of the Spaniards, also
wheat, melons, and perhaps other fruit. Not a vestige of former
cultivation is left; but the platform _r m s_, with a pond in the
centre, at once explains their mode of securing the water for
irrigation. Through the gateway _D_ the drainage of the _mesilla_ was
conducted directly to the platform _r m s_, where the pond _t_ acted as
a reservoir, out of which the fields themselves could be very easily and
equitably supplied with moisture. Whether this was done by channels
radiating from below the curve _r s_ over the area _F_, or by carrying
the water, I cannot tell, neither my informants nor the appearance of
the area giving any clew. But I could not escape being forcibly struck
by this plain and still very forcible
