As many of them now began to ask for tobacco and for paper, to include fragments of it in the form of segars for smoking, and not finding it convenient to gratify them in this respect, we thought it prudent to withdraw, lest a quarrel might ensue. We therefore mounted our horses without molestation, having been detained an hour and a half, and proceeded on our journey, with the agreeable reflection that our deportment had not warranted a supposition that we were conscious of any inferiority in force, but rather that it was dictated by a high courtesy.

A few bisons varied the landscape, which is fatiguing to the eye by its sameness; and after travelling twenty-three miles, we encamped for the night. A [63] large green-headed fly (tabanus) has made its appearance in great numbers, which exceedingly worries our already sufficiently miserable horses. Their range seems to be in a great measure restricted to the luxuriant bottoms, and, like the zimb of Egypt, they appear to roam but little beyond their proper boundaries. If we traversed these fertile portions of the low grounds, which yield a profuse growth of grasses, we were sure of being attacked by them, seizing upon the necks of the horses, and dyeing them with blood; but the refuge of the more elevated surface, and arid barren soil, afforded speedy relief, by banishing our assailants.

Scarcely were our tents pitched, when a thunder-storm, which had been approaching with a strong west wind, burst over us, but was of short continuance.

Wednesday, 2d. After moving a few miles, we halted, and sent out hunters to kill a bison.[102] The confluent rattlesnakes are very abundant, particularly in and about the prairie dog villages; but neither their appearance nor the sound of their rattle excites the attention of our horses; the sagacity of Mr. Seymour's mule, however, seems superior to that of his quadruped companions. He appears to be perfectly aware of the dangerous qualities of these reptiles, and when he perceives one of them near him, he springs so abruptly to one side, as to endanger his rider. Fortunately none of us have been bitten by them during our pedestrian rambles.

A recent trail of some war-party was this morning observed, leading across the river. The hunters returned unsuccessful, and we proceeded on until sunset to a distance of twenty miles. Great numbers of bisons were seen this afternoon, and some antelopes.

Thursday, 3d. The morning was clear and fine, with a temperature of 57 degrees. The antelopes become more numerous as we proceed; one of them trotted up so near to our line as to fall a victim to his curiosity. A considerable number of the coquimbo, [64] or burrowing owl, occurred in a prairie dog village of limited extent. They readily permitted the hunter to approach within gunshot, and we were successful in obtaining a specimen of the bird in good order. Upon examining the several burrows upon which the owls had been observed to be perched, we remarked in them a different aspect from those on which the prairie dog had appeared; they were often in a ruined condition, the sides in some instances fallen in, sometimes seamed and grooved by the action of the water in its course from the surface to the interior, and in other respects presenting a deserted aspect, and, like dilapidated monuments of human art, were the fit abode of serpents, lizards, and owls. The burrows on which we saw the prairie dog were, on the contrary, neat, always in repair, and evinced the operations of industrious tenants. This contrast, added to the form and magnitude of the dwelling, leads us to the belief that the coquimbo owl does not, in this region, excavate its own burrow, as it is said to do in South America and in the West India islands; but rather that it avails itself of the abandoned burrows of this species of marmot, for the purposes of nidification and shelter.

On our arrival at our mid-day resting-place, on the bank of the Arkansa, the water of the river was potable, but in a few minutes it became surcharged with earthy and stercoraceous matters, from the sweepings of the prairie by the late rain, to such a degree that our horses would hardly drink it. There remained however, a short distance below, a small stream of beautifully pellucid water, which rapidly filtrated through a fortuitous embankment of sand and pebbles, and strongly contrasted with the flood with which it was soon again to intermingle. Our travelled distance to-day was twenty-three miles.

Friday, 4th. Proceeded on about six miles, when we forded a small portion of the river to an island which supported a growth of low and distant trees. [65] Here the tents were pitched, with the intention of halting a day or two, to recruit our miserable horses, and to supply ourselves with a store of jerked meat. The hunters were accordingly sent to the opposite side of the river, and in a short time they succeeded in killing four fat cows, which gave employment to all the men in preparing the meat for transportation.

A brisk southerly wind prevailed, that rendered the atmosphere less oppressive than usual.

Saturday, 5th. The wind ceased during the night, and the lowing of the thousands of bisons that surrounded us in every direction, reached us in one continual roar. This harsh and guttural noise, intermediate between the bellowing of the domestic bull and the grunting of the hog, was varied by the shrill bark and scream of the jackals, and the howling of the white wolves (canis mexicanus var.), which were also abundant. These wild and dissonant sounds were associated with the idea of the barren and inhospitable wastes, in the midst of which we were then reposing, and vividly reminded us of our remoteness from the comforts of civilised society. Completed the operation of jerking the meat, of which we had prepared two packs sufficient in weight to constitute a load for one of our horses, and disposed every thing for an early departure to-morrow.
