Several bisons and other game, had been seen in the course of the day, but nothing taken. As our provisions were now exhausted, it was resolved to remain encamped where we were, while parties were sent out in different directions to hunt.[101]
Being now at a place where, as our guide informed us, the Pawnees often cross the Platte, and as it was our intention to ascend on the other side of the river, Major Long rode across to ascertain the practicability {150} of fording; but the summer freshet being now at its height, it was found the river could not be crossed without swimming, and the design was relinquished. Six of our party, including the hunters, were sent out in pursuit of game.
At camp, observations were taken for ascertaining longitude and other purposes. At evening, Mr. Peale returned, having killed an antelope at the distance of ten miles from the camp, and brought it within about four, where being fatigued and hungry, he had made a fire, cooked and ate part of the animal, and left the remainder, suspending a handkerchief near it, to protect it from the wolves. Soon afterwards others returned, and when all were collected, it appeared there had been killed one bison, two antelopes, and a hare, all at a distance from camp. Horses were accordingly sent out to bring in the meat, a part of which we attempted to dry during the night, by cutting it in thin pieces and exposing it over a slow fire, but a storm of wind and rain, which continued greater part of the night, prevented our success in this attempt.
21st. The storm continued throughout the night, and the following day was cold, with a heavy mist from the south-east.
After travelling this day our customary distance, which was about twenty-five miles, we were compelled to halt at a place where we could find no poles to set up our tents. We were fortunate in finding part of a tree which had drifted down the Platte, and which sufficed to make a fire for the cooking of our supper. An Indian dog, who had made his appearance at the encampment on the preceding day, had followed us thus far, but kept aloof, not allowing us to come within one or two hundred yards of him.
On the following morning, six miles from our camp, we arrived at the confluence of the north and south fork of the Platte. We had halted here, and were making preparations to examine the north fork, with a view of crossing it, when we saw two elk plunge into the river a little above us on the same {151} side. Perceiving it was their design to cross the river, we watched them until they arrived on the other side, which they did without swimming. We accordingly chose the same place they had taken, and putting a part of our baggage in a skin canoe, waded across, leading our horses, and arrived safely on the other side; no accident having happened, except the wetting of such of our baggage as was left on the horses.
The north fork at its confluence is about eight hundred yards wide, is shoal and rapid like the Platte, and has a sandy bed. We were informed by our guide, who had been repeatedly to its sources, that it rises within the Rocky Mountains, about one hundred and twenty miles north of the sources of the Platte.
It is probably the river which was mistaken by Captain Pike for the Yellow-stone, and has been laid down as such on his map, whence the mistake has been copied into several others. It has its source in numerous small streams, which descend from the hill surrounding a circumscribed valley within the mountains, called the Bull-pen. This basin is surrounded by high and rugged mountains, except at the place where the north fork passes into the plains. On each side of this strait, or pass, are high and abrupt rocky promontories, which confine the river to a narrow channel. The diameter of the circumscribed valley, called the Bull-pen, is one day's travel, about twenty miles.[102] The upper branches of the north fork have some timber, mostly cotton-wood and willow, and abound in beaver.[103]
From the limited information communicated to the public, on the subject of Mr. Hunt's Expedition to the mouth of the Columbia, commenced in the year 1811, it appears that a part of the men engaged in that undertaking, in their return from the Pacific, crossed the Rocky Mountains from some one of the upper branches of Lewis' river, and falling upon the sources of the north fork of the Platte, descended thence to the Missouri.
{152} On the 28th of June, 1812, Mr. Robert Stewart, one of the partners of the Pacific Fur Company, with two Frenchmen, M'Clellan, and Crooks, left the Pacific ocean with despatches for New York.
