Durst Old York Library 1 Digitized by the Internet Archive in 2013 http://archive.org/details/reportofspecialc00newy_1 REPORT OF A SPECIAL COMMITTEE OF THE dtakwf having pushed the shoal out as the shore line was changed. In illustration of this assertion, we have but to look at the extraor- dinary heaping up of the earth in the angle formed by the Battery wall and Pier No. 1, a heaping up made by the ebb current of the North River, which, as it comes around the pier, is now turned back and forward into eddies by the Battery walls. This current formerly ran through the space now covered by the filling in, and poured the suspended matter into the East River, off Whitehall, from whence it was carried away and distributed in the deep waters of the Bay. But now a large portion of the sediment brought down by the ebb is doubtless rilling in the spaee here with great rapidity ; its effects are still more strongly visible in the section off the Castle where we see changes of six and eight feet m the space of three yards. This is due to the united efforts of the ebbs from the two rivers ; and the time cannot be far distant when — unless dredging is resorted to — the entire space from the Castle to the head of Pier No. 1 will be quite filled in. In addition to the material damage done by thus forcing out into the stream a shoal which was heretofore of little consequence, it may 16 safely be presumed that, in rilling in for the Battery Extension, very liberal supplies have been contributed to the shoals from the dirt carts, as without the security of a regular sea wall, immense quanti- ties of the loose earth must, from time to time, be washed away and added to the shoal ; and it is probable that when the slowly progress- ing enlargement is completed and the walls finished, the changes will be less rapid. The injury is now without other remedy than that of hastening to its completion a work which has proved so seriously dis- astrous to this already crowded part of the harbor, and, by legislation, preventing any extensions beyond the lines of the city as defined by the Harbor Commissioners. I am, very respectfully, Your ob'd't servant, T. Augs. Craven, Lieut t - Comm anding. Prof. A. D. Bache, Sup^t U. S. Coast Survey. \
