Rivers that overran their banks, fever-stricken lowlands where gaunt faces peered out from moldering cabins, bottomless swamps where the mud oozed greasily and where the alligator could be seen slowly moving his repulsive form--all this stretched on for hundreds of miles to horrify and sicken the emigrants who came toiling on foot or struggling upon emaciated horses. Other daring pioneers came by boat, running all manner of risks upon the swollen rivers. Still others descended from the mountains of Tennessee and passed through a more open country and with a greater certainty of self-protection, because they were trained from childhood to wield the rifle and the long sheath-knife.
