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. Sunday, 6th. An unusual number of wolves and jackals hovered around our encampment of last night, attracted probably by the smell of the meat. Resumed our journey on a fine cloudless morning, with a strong and highly agreeable breeze from the south. We were now traversing the great bend of the river.[103] Travelled twenty-three miles to-day, and shot two bulls, which were now poor, and their flesh of a disagreeable rank taste and scarcely eatable; we therefore contented ourselves with the tongues and marrow-bones. Monday, 7th. The mercurial column of the thermometer at sunrise, for a few days past, has ranged {66} between 42 and 67 degrees, and the atmosphere is serene and dry. The services of the two French Pawnee interpreters, Bijeau and Ledoux, had terminated, agreeably to their contract, at Purgatory Creek; but having been highly serviceable to us on our route, it became desirable, particularly on the departure of our companions for Red river, that they should accompany us still farther, until we should have passed beyond the great Indian war-path, here so widely outspread. This they readily consented to, as they regarded a journey from that point to their home, at the Pawnee villages, as somewhat too hazardous to be prudently attempted by only two individuals, however considerable their qualifications, and intimate their familiarity with the manners of those whom they would probably meet.
