The other pier, (called No. 10 in the general series,) for which a piled foundation has been prepared, is near the centre of the river channel. The stratum of boulders lies much lower at this place, and required an excavation to be carried 30 feet below common high water line, before a suitable stratum for driving piles could be reached. When the excavation was carried to this depth, boring was made to ascertain if rock could be found for the foundation but after going down Avithout success to a depth of 70 ;

feet below high water, the effort was abandoned, and the driving of piles commenced, as the only means of securing the foundation. The piles were driven at three feet apart from centre to centre, to the depth of 30 to 35 feet. " come home" with great It may be remarked, that all the piling for the bridge has regularity and firmness, and gives great confidence that it will afford an unyielding support to the structure. The foundations for the water piers are yet to be put down two of ;

them will probably require bearing piles to support them, and rock is expected to be found for the other. The coffer dams are all put down and embanked, and the work of emptying them is soon to commence. A temporary pipe 3 feet in diameter is laid down, (partly on the embankment of the coffer dams,) which now conveys the water across this valley. Gate chambers are arranged at each end of the bridge, with gates to regulate the
