Read it through once

More of the river's freaks. In times past, the channel used to strike above Island 37, by Brandywine Bar, and down towards Island 39. Afterward, changed its course and went from Brandywine down through Vogelman's chute in the Devil's Elbow, to Island 39--part of this course reversing the old order; the river running _up_ four or five miles, instead of down, and cutting off, throughout, some fifteen miles of distance. This in 1876. All that region is now called Centennial Island.
