Read it through once

'Oh, yes, eight years ago, the captain was on top; but it's Smith's turn now. Eight years ago a boat used to go up the river with every stateroom full, and people piled five and six deep on the cabin floor; and a solid deck-load of immigrants and harvesters down below, into the bargain. To get a first-class stateroom, you'd got to prove sixteen quarterings of nobility and four hundred years of descent, or be personally acquainted with the nigger that blacked the captain's boots. But it's all changed now; plenty staterooms above, no harvesters below--there's a patent self-binder now, and they don't have harvesters any more; they've gone where the woodbine twineth--and they didn't go by steamboat, either; went by the train.'
