On the examination we were accompanied by men prepared to attend to any work that might appear necessary and as soon as we passed over a district, they received their ;

directions, and immediately proceeded with such work as it was considered expedient to do. Some defects were discovered, the greater part of which appeared to have been overlooked in previous examinations, which now were discovered, most probably from the clean state of the masonry, after a washing of near five months there was, however, ;

evidence that a small additional settlement had taken place in a few instances. The work required was vigorously prosecuted to completion, and on the 16th, eight days after the water was shut off, it was again let into the aqueduct. In the main, the aqueduct appeared substantially well, and the defects not such as to give serious apprehension that its successful action would have been impaired by them for a long time. Enough, however, was discovered to show the propriety of the examination. The two leaks that had appeared on the outside were successfully stopped by the work done inside, and nothing has since appeared to indicate any defect in the work.

The reservoirs, during the time the water was shut off from the aqueduct, proved amply sufficient for the supply of the city, and indeed much beyond a supply, as a large quantity of water had to be wasted from the receiving reservoir before the lower end of the aqueduct could be examined.
