In this part of the journey there was no lack of provisions, for the prairies were covered with immense herds of buffalo.  These, in general, are animals of peaceful demeanor, grazing quietly like domestic cattle; but this was the season when they are in heat, and when the bulls are usually fierce and pugnacious.  There was accordingly a universal restlessness and commotion throughout the plain; and the amorous herds gave utterance to their feelings in low bellowings that resounded like distant thunder.  Here and there fierce duellos took place between rival enamorados; butting their huge shagged fronts together, goring each other with their short black horns, and tearing up the earth with their feet in perfect fury.

In one of the evening halts, Pierre Dorion, the interpreter, together with Carson and Gardpie, two of the hunters, were missing, nor had they returned by morning.  As it was supposed they had wandered away in pursuit of buffalo, and would readily find the track of the party, no solicitude was felt on their account.  A fire was left burning, to guide them by its column of smoke, and the travellers proceeded on their march.  In the evening a signal fire was made on a hill adjacent to the camp, and in the morning it was replenished with fuel so as to last throughout the day.  These signals are usual among the Indians, to give warnings to each other, or to call home straggling hunters; and such is the transparency of the atmosphere in those elevated plains, that a slight column of smoke can be discerned from a great distance, particularly in the evenings.  Two or three days elapsed, however, without the reappearance of the three hunters; and Mr. Hunt slackened his march to give them time to overtake him.

A vigilant watch continued to be kept upon the movements of Rose, and of such of the men as were considered doubtful in their loyalty; but nothing occurred to excite immediate apprehensions.  Rose evidently was not a favorite among his comrades, and it was hoped that he had not been able to make any real partisans.

On the 10th of August they encamped among hills, on the highest peak of which Mr. Hunt caused a huge pyre of pine wood to be made, which soon sent up a great column of flame that might be seen far and wide over the prairies.  This fire blazed all night, and was amply replenished at daybreak; so that the towering pillar of smoke could not but be descried by the wanderers if within the distance of a day’s journey.

It is a common occurrence in these regions, where the features of the country so much resemble each other, for hunters to lose themselves and wander for many days, before they can find their way back to the main body of their party.  In the present instance, however, a more than common solicitude was felt, in consequence of the distrust awakened by the sinister designs of Rose.

The route now became excessively toilsome, over a ridge of steep rocky hills, covered with loose stones.  These were intersected by deep valleys, formed by two branches of Big River, coming from the south of west, both of which they crossed.  These streams were bordered by meadows, well stocked with buffaloes.  Loads of meat were brought in by the hunters; but the travellers were rendered dainty by profusion, and would cook only the choice pieces.
