The swamp is more than seventy miles long by about thirty-five miles wide, and, as a piece of bottomless ooze, its superior cannot be found in the United States. There are just two roads crossing it, one running from Hall's Ferry, at Point Pleasant, Missouri, and the other from Mitchell's Ferry, thirty-five miles below. These roads are mere bog-paths in themselves, being heavily overlaid with underbrush and corduroy logs, yet they afford the only means of crossing this vast morass. The period of the annual overflow turns it into a turbid, sluggish lake, the roads being then deeply buried under water; but even in the dryest seasons the greater portion of the swamp is a bottomless slime of mud and putrefying vegetation. Large tracts of thickly-wooded land are contained within the limits of the swamp, and these constitute a semi-substantial basis for the two roads which run through them; but even these clumps are impassable at most seasons, except along the artificially-constructed roads. Sometimes, for miles and miles, nothing but the rankest of swamp-vegetation is seen, growing in wild profusion and covering the treacherous ooze with a close network of leaves and branches, until the surface looks firm enough to be taken for solid ground; but should any unfortunate traveler venture to cross such a spot, his limbs would be clogged by these clinging water-plants, his feet would find no secure resting-place, and, sinking rapidly deeper and deeper into the mire, his bones would find a sepulcher where nothing but a general natural convulsion would ever disturb them. Still, there are occasional islands of firm ground through this section, and these have become the resort of lawless characters of every nationality and degree of crime. Over the entrance to Nigger-Wool Swamp might be placed, with perfect truthfulness, the motto: "Who enters here leaves hope behind." Each man is a law unto himself, and he must maintain his rights by the strong arm and the ready shot-gun. In one thing only are the dwellers of the swamp united, namely: a bitter and deadly resistance to the law. No officer of justice ventures therein to perform any of the duties of his office; unless backed by a powerful body of determined men, he would never return alive, and, if so accompanied, he would never succeed in catching a glimpse of any criminal whom he might be seeking.
