Excerpt: ... rate sum will be adequate to their removal, I should say g 1000 wouid ue an ample allowance. ' I think such a slope as has been described may be made for g 250, but as it will be necessary to raise the other parts of the dams, perhaps 8 inches, we will say g 300. The proper plan of attaching them to these already buili, will be to cut down the top of the dam at the slope, 8 inches, and raise the remaining part of the dam as much. When ihere is a tolerable supply of water, it is probable it may be about 8 inches deep at the slope, and of course level with the present daui, and the present head for the mills kept up; but when low, a thick plank, 8 inches wide, placed across the opening, will give the usual head, which can be easily removed when the water rises. The sums of g 1,500 for five slopes, and g 1,000 for clearing the bed of the river, make g 2,500, and brings such a navigation as I believe will be quite satisfactory, down to the company's dam in the 44th mile. I would then propose, that from this point down to the junction of the two rivers, the navigation should be completed according to the original plan. This will require 7 dams of rather more than 9 feet, with a lock and slope in each. The average length will probably be about 2r5 feet, and may be stated at g 3,000 per dam, which will amount to g 21,000. From the confluence of the rivers to the Pennsylvania line, 1 would propose using the bed of the river: To improve which, in a style to suit the navigation of flat bottom boats and rafts, and to give the greatest depth to batteaux in low water, that circumstances will permit, may cost about the same as to improve for batteaux. navigation only; by the foregoing estimates this will amount to g 7,150. To these may be added the cost of the company'...
