On the following morning they still observed the Indian track, but after a time they came to where it separated in every direction, and was lost.  This showed that the band had dispersed in various hunting parties, and was, in all probability, still in the neighborhood; it was necessary, therefore, to proceed with the utmost caution.  They kept a vigilant eye as they marched, upon every height where a scout might be posted, and scanned the solitary landscapes and the distant ravines, to observe any column of smoke; but nothing of the kind was to be seen; all was indescribably stern and lifeless.

Towards evening they came to where there were several hot springs, strongly impregnated with iron and sulphur, and sending up a volume of vapor that tainted the surrounding atmosphere, and might be seen at the distance of a couple of miles.

Near to these they encamped in a deep gully, which afforded some concealment.  To their great concern, Mr. Crooks, who had been indisposed for the two preceding days, had a violent fever in the night.

Shortly after daybreak they resumed their march.  On emerging from the glen, a consultation was held as to their course.  Should they continue round the skirt of the mountain, they would be in danger of falling in with the scattered parties of Blackfeet, who were probably hunting in the plain.  It was thought most advisable, therefore, to strike directly across the mountain, since the route, though rugged and difficult, would be most secure.  This counsel was indignantly derided by M’Lellan as pusillanimous.  Hot-headed and impatient at all times, he had been rendered irascible by the fatigues of the journey, and the condition of his feet, which were chafed and sore.  He could not endure the idea of encountering the difficulties of the mountain, and swore he would rather face all the Blackfeet in the country.  He was overruled, however, and the party began to ascend the mountain, striving, with the ardor and emulation of young men, who should be first up.  M’Lellan, who was double the age of some of his companions, soon began to lose breath, and fall in the rear.  In the distribution of burdens, it was his turn to carry the old beaver trap.  Piqued and irritated, he suddenly came to a halt, swore he would carry it no further, and jerked it half-way down the hill.  He was offered in place of it a package of dried meat, but this he scornfully threw upon the ground.  They might carry it, he said, who needed it; for his part, he could provide his daily bread with his rifle.  He concluded by flinging off from the party, and keeping along the skirts of the mountain, leaving those, he said, to climb rocks, who were afraid to face Indians.  It was in vain that Mr. Stuart represented to him the rashness of his conduct, and the dangers to which he exposed himself:  he rejected such counsel as craven.  It was equally useless to represent the dangers to which he subjected his companions; as he could be discovered at a great distance on those naked plains, and the Indians, seeing him, would know that there must be other white men within reach.  M’Lellan turned a deaf ear to every remonstrance, and kept on his wilful way.
