It is believed that merely a cut through the chord of this circuit of about half a mile, in easy digging and of little depth, would effectually surmount these obstacles. The other rapids which are neither long, sharp, nor many, descend from deep water immediately above them, and may, tlierefbre be permanently deepened at a moderate expence. The residue of the impediments in all this part of the river are occasioned by trees fallen into the river eitlier accidentally, or cut down by the inhabitants. The wiiole expence of improving the river from the falls to Fort Schuyler will probably not exceed X3,000.

tion ABC, see tlie plan C. The water in tlie Mohawk at the point A is one foot four inclies and four tentlis of an incli liigher than at the point C. Obstructions by lieaps of fallen trees, prevented us taking- a section of the Canal in the direction which it would run, but apparently the mean depth of tlie earth to be removed for fonniiig the Canal would be about twelve feet at the greatest depth, hence ab(jut 642,240 cubic feet of earth must be removed : The ground thougli soft is so much interwoven with the roots of trees and the work will also be so much retarded by the influx ot water into the Canal whilst digging, that it is supposed that one man could not remove above fifty cubic feet per day, hence 12,84^ days for one man would be required; which at 4s. per day amounts to ^£2,509. In very dry times, such as the present, the water in the Mohawk is so httle that none can be spaied to increase the quantity in Wood Creek.
