MR. BOOLEY found it singularly interesting to observe the various stages of civilisation obtaining on the banks of these mighty rivers. Leaving the luxury and brightness of New Orleans—a somewhat feverish luxury and brightness, he observed, as if the swampy soil were too much enriched in the hot sun with the bodies of dead slaves—and passing various towns in every stage of progress, it was very curious to observe the changes of civilisation and of vegetation too. Here, where the doomed Negro race were working in the plantations, while the republican overseer looked on, whip in hand, tropical trees were growing, beautiful flowers in bloom; the alligator, with his horribly sly face, and his jaws like two great saws, was basking on the mud; and the strange moss of the country was hanging in wreaths and garlands on the trees, like votive offerings. A little farther towards the west, and the trees and flowers were changed, the moss was gone, younger infant towns were rising, forests were slowly disappearing, and the trees, obliged to aid in the destruction of their kind, fed the heavily-breathing monster that came clanking up those solitudes, laden with the pioneers of the advancing human army. The river itself, that moving highway, showed him every kind of floating contrivance, from the lumbering flat-bottomed boat, and the raft of logs, upward to the steamboat, and downward to the poor Indian’s frail canoe. A winding thread through the enormous range of country, unrolling itself before the wanderer like the magic skein in the story, he saw it tracked by wanderers of every kind, roaming from the more settled world, to those first nests of men. The floating theatre, dwelling-house, hotel, museum, shop; the floating mechanism for screwing the trunks of mighty trees out of the mud, like antediluvian teeth; the rapidly-flowing river, and the blazing woods; he left them all behind—town, city, and log-cabin, too; and floated up into the prairies and savannahs, among the deserted lodges of tribes of savages, and among their dead, lying alone on little wooden stages with their stark faces upward towards the sky. Among the blazing grass, and herds of buffaloes and wild horses, and among the wigwams of the fast-declining Indians, he began to consider how, in the eternal current of progress setting across this globe in one unchangeable direction, like the unseen agency that points the needle to the pole, the Chiefs who only dance the dances of their fathers, and will never have a new figure for a new tune, and the Medicine-men who know no Medicine but what was Medicine a hundred years ago, must be surely and inevitably swept from the earth, whether they be Choctawas, Mandans, Britons, Austrians, or Chinese.
