Read it through once

In the heyday of the steamboating prosperity, the river from end to end was flaked with coal-fleets and timber rafts, all managed by hand, and employing hosts of the rough characters whom I have been trying to describe. I remember the annual processions of mighty rafts that used to glide by Hannibal when I was a boy,--an acre or so of white, sweet-smelling boards in each raft, a crew of two dozen men or more, three or four wigwams scattered about the raft's vast level space for storm-quarters,--and I remember the rude ways and the tremendous talk of their big crews, the ex-keelboatmen and their admiringly patterning successors; for we used to swim out a quarter or third of a mile and get on these rafts and have a ride.
