vigorous note to President Santa Anna, calling his attention to it, and,
receiving an unsatisfactory reply, declared the armistice at an end.

General Scott, with Worth's division, was now occupying Tacubaya, a
village some four miles south-west of the City of Mexico, and extending
from the base up the mountain-side for the distance of half a mile.
More than a mile west, and also a little above the plain, stands Molino
del Rey. The mill is a long stone structure, one story high and several
hundred feet in length. At the period of which I speak General Scott
supposed a portion of the mill to be used as a foundry for the casting
of guns. This, however, proved to be a mistake. It was valuable to the
Mexicans because of the quantity of grain it contained. The building is
flat roofed, and a line of sand-bags over the outer walls rendered the
top quite a formidable defence for infantry. Chapultepec is a mound
springing up from the plain to the height of probably three hundred
feet, and almost in a direct line between Molino del Rey and the western
part of the city. It was fortified both on the top and on the rocky and
precipitous sides.

The City of Mexico is supplied with water by two aqueducts, resting on
strong stone arches. One of these aqueducts draws its supply of water
from a mountain stream coming into it at or near Molino del Rey, and
runs north close to the west base of Chapultepec; thence along the
centre of a wide road, until it reaches the road running east into the
city by the Garita San Cosme; from which point the aqueduct and road
both run east to the city. The second aqueduct starts from the east
base of Chapultepec, where it is fed by a spring, and runs north-east to
the city. This aqueduct, like the other, runs in the middle of a broad
road-way, thus leaving a space on each side. The arches supporting the
aqueduct afforded protection for advancing troops as well as to those
