This noble city contains many fine and magnificent houses; wilich may be accounted for from the fact, that all the nobility of the country, who are the vassals of Moctezuma, have houses in the city, in which they reside a certain part
of the year, and besides, there are numerous wealthy citizens who also possess fine houses. All these persons, in
addition to the large and spacious apartments for ordinary purposes, have others, both upper and lower, that contain
conservatories of flowers. Along one of the causeways that lead into the city are laid two pipes, constructed of
masonry, each of which is two paces in width, and about five feet in height. An abundant supply of excellent water,
forming a volume equal in bulk to the human body, is conveyed by one of these pipes, and distributed about the city,
where it is used by the inhabitants for drinking and other purposes. The other pipe, in the meantime, is kept empty
until the former requires to be cleansed, when the water is let into it and continues to be used till the cleansing is
finished. As the water is necessarily carried over bridges on account of the salt water crossing its route, reservoirs
resembling canals are constructed on the bridges, through which the fresh water is conveyed. These reservoirs are of
the breadth of the body of an ox, and of the same length as the bridges. The whole city is thus served with water,
which they carry in canoes through all the streets for sale, taking it from the aqueduct in the following manner: the
canoes pass under the bridges on which the reservoirs are placed, when men stationed above fill them with water, for
which service they are paid.
