of 56 ft. at its highest point above the ground. The object of this
bridge was to convey the channel of the aqueduct at a sufficient height
into a reservoir on the edge of the valley.

The remains of this bridge leave no doubt that it was purposely destroyed
by barbarians; some of the arches near the end of it remain, while the
rest have been thrown down, some on one side and some on the other; but
happily the arches next to the reservoir, at the end of the bridge and on
the edge of the valley, remain, and the reservoir itself is still in part
intact, supported on a huge mass of masonry. Four holes are to be seen in
that part of the front of the reservoir which is left, being the holes
from which the lead pipes descended into the valley. There must have been
nine of these pipes in all. These holes are elliptical in shape, being 12
in. high by 9½ in. wide, and the interior of the reservoir is still seen
to be covered with cement. The walls of the reservoir were about 2 ft. 7
in. thick, and were strengthened by ties of iron; it had an arched stone
roof in which there was an opening for access. From this the nine lead
pipes descended the side of the valley supported on a construction of
masonry, crossed the river by an aqueduct bridge, and ascended into
another reservoir on the other side, entering the reservoir at its upper
part just below the spring of the arches of the roof. From this reservoir
the aqueduct passed to the next on the edge of the large and deep valley
of Bonnan, being underground twice and having three bridges on its
course, the last of which, the sixteenth on the course of the aqueduct,
ends in a reservoir on the edge of the valley. Only one of the openings
by which the siphons, of which there were probably ten, started from the
reservoir is now left. The bridge across the valley below had thirty
arches, and was about 880 ft. long by 24 ft. wide.

A number of the arches still remain standing, and, the pillars of the
