Read it through once

Steamboats passed up and down every hour or so. Those belonging to the little Cairo line and the little Memphis line always stopped; the big Orleans liners stopped for hails only, or to land passengers or freight; and this was the case also with the great flotilla of "transients." These latter came out of a dozen rivers--the Illinois, the Missouri, the Upper Mississippi, the Ohio, the Monongahela, the Tennessee, the Red River, the White River, and so on; and were bound every whither and stocked with every imaginable comfort or necessity which the Mississippi's communities could want, from the frosty Falls of St. Anthony down through nine climates to torrid New Orleans.
