The Escape of Mr. Trimm by Irvin S. Cobb

There was a swamp known as Little Niggerwool, to distinguish it from Big Niggerwool, which lay across the river. It was traversable only by those who knew it well -- an oblong stretch of tawny mud and tawny water, measuring maybe four miles its longest way and two miles roughly at its widest; and it was full of cypress and stunted swamp oak, with edgings of canebrake and rank weeds; and in one place, where a ridge crossed it from side to side, it was snaggled like an old jaw with dead tree trunks, rising close-ranked and thick as teeth. It was untenanted of living things -- except, down below, there were snakes and mosquitoes, and a few wading and swimming fowl; and up above, those big woodpeckers that the country people called logcocks -- larger than pigeons, with flaming crests and spiky tails -- swooping in their long, loping flight from snag to snag, always just out of gunshot of the chance invader, and uttering a strident cry which matched those surroundings so fitly that it might well have been the voice of the swamp itself.

On one side little Niggerwool drained its saffron waters off into a sluggish creek, where summer ducks bred, and on the other it ended abruptly at a natural bank of high ground, along which the county turnpike ran. The swamp came right up to the road and thrust its fringe of reedy, weedy undergrowth forward as though in challenge to the good farm lands that were spread beyond the barrier. At the time I am speaking of it was mid-summer, and from these canes and weeds and waterplants there came a smell so rank as almost to be overpowering. They grew thick as a curtain, making a blank green wall taller than a man's head.
