From thence to the head of Hustis rapids the channel is no where less than three and a half feet deep and the average width of the stream is from one hundred and fifty to two hundred feet, and the current is gentle-From Hustis rapids to Pecks rapids several sand bars obstruct the navigation which require a small expenditure for their removal. From the head of Peck's to the foot of Johnson's rapids there is a descent of 47.896 feet in a distance of eleven and one eighth miles requiring locks and dams.
