All the difficulty and danger inseparably connected with the use of coffer dams, of the great size and depth required for this pier, have been successfully overcome, and the masonry will, in a few weeks, be raised above the high water of the river. The coffer dams for piers Nos. 11, 12, and 13, are in their places, and embanked, but none of them have yet been cleared of water, or the character of the foundations ascertained. It is expected, however, that 11 and 12, and perhaps

13, will require the same operations of piling and timbering, previous to laying down any part of the masonry. The present condition of the work is as follows : The foundations of piers Nos. are laid and secured, and the masonry of all, except No. 10, is 2, 3, 4, 5, 6, 7, 8, 9, and 10, carried above high-water mark from 4 to 15 feet. The foundations of Nos. 11, 12, and 13, which are river piers, remain to be put down, and Nos. 1 and 14 at the two ends of the bridge. These last will be built upon rock, and at a considerable height above the water. A very large quantity of cut stone, for various parts of the work, is prepared, and much of it brought upon the ground. All, or nearly all, the timber for the centres of the arches is delivered, and the amount of machinery and arrangements of the contractors for carrying on the work is such, that if the commissioners should feel authorised to urge it forward, there is no doubt but it could be carried up as fast as a due regard to its stability would warrant. RECEIVING RESERVOIR AT YORKVILLE. The excavation at this place was carried on at a moderate rate during the whole winter, and on the opening of the spring, such additions were made to the force employed there, that the work was fitted for the reception of water on 27th June.
