In the progress of preparing foundations for the piers of the bridge, an embankment has been formed across the River and the pipe leaving the Aqueduct on the north side of the valley follows down the slope of the hill, and crossing over the River upon this embankment, ascends on the south side again to the Aqueduct. At the bottom or lowest point in this pipe, a branch pipe of 1 foot diameter has been connected, extending a distance of 80 feet from it at right angles and horizontally :
the end of this pipe is turned upwards to form a jet, and iron plates are fastened upon it giving any form that may be desired to the water issuing. The level of this branch pipe is about 120 feet below the bottom of the Aqueduct on the north side of the valley ; affording an opportunity for a beautiful jet deau ; --such an one as cannot be obtained at
the fountains in the city. From an orifice of seven inches diameter the column of water rises to a height of 115 feet
when there is only a depth of 2 feet of water in the
Aqueduct.
To those who had watched over the work during its construction and looked for its successful operation, this was peculiarly gratifying. To see the water leap from this
opening and rise upwards with such force and beauty, occasioned pleasing emotions and gave proof that the design and construction of the work were alike faultless, and that all the fondest hopes of its projectors would be realized.
