At some distance below this dam and lock, a canal may be led from the river on the south side, secured with guard gates, and run througli low lands, and well slieltered along the foot of tlie hills and re-enter the river at Daniel Peck's, Avhicli is supposed to be about N^ 5, and tluTS, with tlie necessary locks, every difficulty would be obviated. For want of accurate surveys and implements to determine the quantity, and kind of earth and stone, or rock, to be removed, it is absolutely impossible to ascertain Avith any degree of precision, tlie expence that would attend the proper improvement of tliis part of the river ; it certainly will be considerable, probably not less than <£20,000.

From Sclioliara Creek to the falls, it does not appear necessary to form any Canals, tlie rocks which impede the passage of boats in the Caughnawaga, Keetar's and Haycock's rapids, and other places, will be easily removed by rolling them to the shore, or when too lai-ge by blowing them. Those rapids which are too shallow may be deepened by removing the stone and gravel, as the water above is in general deep, and if cuts are made through the gravel and sand banks, which obstruct the river about Fox's Creek, and a Utile higher up the navigation will be such as the act contemplates, and the expence will probably not exceed £2,000.

The portage at the Little Falls will be a heavy part of the work, -- the plan herewith delivered marked A, will exhibit the tract of a Canal, -- that marked B,' a section thereof; the heiglit to be surmounted is thirty-nine feet two indies, and will require first a strong work at t'le point B, to pi-event the Canal and Locks from being overflowed, and damaged in high freshes; at
