Samuel Augustus Mitchell (1792-1868)
Philadelphia: S. Augustus Mitchell, Jr, 1867. "The Mississippi River is navigable for steamboats, with but partial interuption, as far north as the Falls of St. Anthony, a distance of 2037 miles, and, at seasons, as far as Sauk Rapids, about 100 miles farther; its course, however, is extremely crooked, and not unfrequently a bend occurs from 20 to 30 miles round, where the distance across is not more than a mile or two. In some instances, however, these distances have been shortened, by what is termed "cut-offs," which are made by opening a narrow channel across the neck of a bend, when, on admitting the water, the current, running with such velocity, soon forms a channel both wide and deep enough for the largest steamboats to go through....The whirls, or eddies, caused by the striking peculiarities of the river in the uniformity of its meanders, are termed "points" and "bends," which have the precision, in many instances, as though they had been struck by the sweep of a compass. These are so regular, that the flat-boatmen frequently calculate distances by them: instead of the number of miles, they estimate their progress by the number of bends they have passed."
