July 17th [1852]...Tucson
is the most northern town in Mexico, and a very old place. It is
found on the oldest maps, and is referred to by the early
missionaries. It has always been, and is to this day, a presidio
or garrison; but for which the place could not be sustained. In
its best days it boasted a population of a thousand souls, now
diminished to about one third that number. It stands on the
plateau adjoining the fertile valley watered by the Santa Cruz
River...In addition to the river alluded to, there are some
springs near the base of a hill a mile to the west of the town,
which furnish a copious supply of water. Near these is a hamlet,
and a large hacienda, which in former times must have been very
rich. It is now in a decayed state, and but a small portion of
its fine lands are cultivated. This hacienda is seen in the
foreground of the annexed sketch of Tucson.
