For a week they continued their voyage, exposed to almost incessant rains. The bodies of drowned buffaloes floated past them in vast numbers; many had drifted upon the shore, or against the upper ends of the rafts and islands. These had attracted great flights of turkey-buzzards; some were banqueting on the carcasses, others were soaring far aloft in the sky, and others were perched on the trees, with their backs to the sun, and their wings stretched out to dry, like so many vessels in harbor, spreading their sails after a shower.

The turkey-buzzard (vultur aura, or golden vulture), when on the wing, is one of the most specious and imposing of birds. Its flight in the upper regions of the air is really sublime, extending its immense wings, and wheeling slowly and majestically to and fro, seemingly without exerting a muscle or fluttering a feather, but moving by mere volition, and sailing on the bosom of the air, as a ship upon the ocean. Usurping the empyreal realm of the eagle, he assumes for a time the port and dignity of that majestic bird, and often is mistaken for him by ignorant crawlers upon the earth. It is only when he descends from the clouds to pounce upon carrion that he betrays his low propensities, and reveals his caitiff character. Near at hand he is a disgusting bird, ragged in plumage, base in aspect, and of loathsome odor.

On the 17th of April Mr. Hunt arrived with his party at the station near the Nodowa River, where the main body had been quartered during the winter.

THE weather continued rainy and ungenial for some days after Mr. Hunt’s return to Nodowa; yet spring was rapidly advancing and vegetation was putting forth with all its early freshness and beauty. The snakes began to recover from their torpor and crawl forth into day; and the neighborhood of the wintering house seems to have been much infested with them. Mr. Bradbury, in the course of his botanical researches, found a surprising number in a half torpid state, under flat stones upon the banks which overhung the cantonment, and narrowly escaped being struck by a rattlesnake, which darted at him from a cleft in the rock, but fortunately gave him warning by his rattle.

The pigeons, too, were filling the woods in vast migratory flocks. It is almost incredible to describe the prodigious flights of these birds in the western wildernesses. They appear absolutely in clouds, and move with astonishing velocity, their wings making a whistling sound as they fly. The rapid evolutions of these flocks wheeling and shifting suddenly as if with one mind and one impulse; the flashing changes of color they present, as their backs their breasts, or the under part of their wings are turned to the spectator, are singularly pleasing. When they alight, if on the ground, they cover whole acres at a time; if upon trees, the branches often break beneath their weight. If suddenly startled while feeding in the midst of a forest, the noise they make in getting on the wing is like the roar of a cataract or the sound of distant thunder.

A flight of this kind, like an Egyptian flight of locusts, devours everything that serves for its food as it passes along. So great were the numbers in the vicinity of the camp that Mr. Bradbury, in the course of a morning’s excursion, shot nearly three hundred with a fowling-piece. He gives a curious, though apparently a faithful, account of the kind of discipline observed in these immense flocks, so that each may have a chance of picking up food. As the front ranks must meet with the greatest abundance, and the rear ranks must have scanty pickings, the instant a rank finds itself the hindmost, it rises in the air, flies over the whole flock and takes its place in the advance. The next rank follows in its course, and thus the last is continually becoming first and all by turns have a front place at the banquet.

The rains having at length subsided, Mr. Hunt broke up the encampment and resumed his course up the Missouri.
