While these arrangements were in progress in the camp of Captain
Bonneville, there was a sudden bustle and stir in the camp of
Fontenelle. One of the partners of the American Fur Company had arrived,
in all haste, from the rendezvous at Pierre's Hole, in quest of the
supplies. The competition between the two rival companies was just now
at its height, and prosecuted with unusual zeal. The tramontane concerns
of the Rocky Mountain Fur Company were managed by two resident
partners, Fitzpatrick and Bridger; those of the American Fur Company,
by Vanderburgh and Dripps. The latter were ignorant of the mountain
regions, but trusted to make up by vigilance and activity for their want
of knowledge of the country.

Fitzpatrick, an experienced trader and trapper, knew the evils of
competition in the same hunting grounds, and had proposed that the
two companies should divide the country, so as to hunt in different
directions: this proposition being rejected, he had exerted himself to
get first into the field. His exertions, as have already been shown,
were effectual. The early arrival of Sublette, with supplies, had
enabled the various brigades of the Rocky Mountain Company to start
off to their respective hunting grounds. Fitzpatrick himself, with his
associate, Bridger, had pushed off with a strong party of trappers, for
a prime beaver country to the north-northwest.

This had put Vanderburgh upon his mettle. He had hastened on to
meet Fontenelle. Finding him at his camp in Green River valley, he
immediately furnished himself with the supplies; put himself at the
head of the free trappers and Delawares, and set off with all speed,
determined to follow hard upon the heels of Fitzpatrick and Bridger. Of
the adventures of these parties among the mountains, and the disastrous
effects of their competition, we shall have occasion to treat in a
