These are all the losses which have come to our knowledge on the Crotori River, and all the losses to everybody above and below the dam, including the dam, are considerably inside of $75,000."

No other parts of the aqueduct were injured by the storm, and the Commissioners conclude this their first report with expressions of satisfaction, that thus far " the aqueduct on the line stood remarkably well, the culverts had been sufficient to discharge the waters from the valleys and streams, and the embankments had been but little washed or

damaged by the unprecedented storm." The prevalence of heavy rains in the spring of 1841, retarded the reconstruction of the Croton dam, which was contracted for anew, at an increased price indeed, but of larger dimensions and more durable materials ; and delayed operations on the yet unfinished portion of the line.

The work had been found to withstand, with very little injury, the severe cold and the unusual floods and rains of the past season. The beautiful bridge at Sing Sing exhibited not the least settlement or defect and, with the exception of some spots where, in ;

order to maintain the grade line across low grounds, the aqueduct rests on dry foundation walls, in which slight settlement had occurred, the whole work stood admirably.

In their semi-annual report of 12th July, 1841, the Commissioners thus briefly report the doings of the six months :

The works on this island, including the reservoirs, the mains, Clendening Valley bridges, and the tunnels, have been progressing during the summer, although retarded from the want of punctual payments. m The foundation for the bridge over the Harlem River, so far as piers Nos. 7, 8 and 9 are concerned, has been laid in the bed of the river, and the sinking of the coffer dams has been attended with less difficulty than was apprehended.
