Fremont and his party, after traveling something over three hundred miles from the mouth of the Kansas reached the Platte river, where they encamped in a charming place near Grand Island. The country was most beautiful, though they suffered somewhat from the violent storms which frequently broke over them.

The noon halt was made and all were lounging about the camp, when one of the men on guard called an alarm. Everybody sprang to his feet and grasped his rifle, expecting an attack from Indians. A strange wild looking company were seen approaching, but, as they came closer, they were discovered to be white men. They were a striking sight, numbering fourteen, in the most ragged and woebegone condition imaginable. They had been on a trapping expedition, but having met with nothing but disasters from the beginning, were now straggling back to St. Louis on foot.

The explorers proceeded at a leisurely pace that day and having gone into camp, observed three Indians drawing near, one of whom was a boy about a dozen years of age. They were Cheyennes that had been out among the Pawnees to steal horses, but having met with no success, were returning home. Catching sight of the white men, they unhesitatingly entered camp, confident of being treated well, as of course proved to be the case. After supper one of the warriors drew a rude but correct map of the country around them, and gave it to Fremont.

On the first of July, while riding over a delightful prairie country, on the right bank of the river, a herd of buffaloes, numbering nearly a thousand, came up from the water and began slowly crossing the plain, cropping the grass as they went. As the prairie was three miles broad only, a fine opportunity was given the hunters to charge before the animals could scatter among the hills.

The fleetest horses were quickly saddled and Carson, Fremont, and Maxwell prepared for the chase. By that time the herd was a half mile away and they did not notice the hunters until they were within three hundred yards. Then followed an agitation of the animals, quickly followed by their precipitate flight. The horses dashed after them. A crowd of bulls brought up the rear, they having stationed themselves there to defend the females. Every once in a while they would whirl about and stare, snorting at the horsemen, as if they had made up their minds to fight; but when the hunters came nigher, they turned about and plunged after the herd. Describing the exciting incident, Fremont wrote;

"In a few moments, during which we had been quickening our pace, we were going over the ground like a hurricane. When at about thirty yards we gave the usual shout and broke into the herd. We entered on the side, the mass giving away in every direction in their heedless course. Many of the bulls, less fleet than the cows, paying no heed to the ground, and occupied solely with the hunters, were precipitated to the earth with great force, rolling over and over with the violence of the shock, and hardly distinguishable in the dust. We separated, on entering, each singling out his game.

"My horse was a trained hunter, famous in the west under the name of Proveau, and with his eyes flashing and the foam flying from his mouth, he sprang on after the cow like a tiger. In a few moments he brought me alongside of her. Rising in the stirrups, I fired, at the distance of a yard, the ball entering at the termination of the long hair, passing near the heart. She fell headlong at the report of the gun. Checking my horse, I looked around for my companions.

"At a little distance Kit was on the ground engaged in tying his horse to the horns of a cow, which he was preparing to cut up. Among the scattered band at some distance, I caught a glimpse of Maxwell. While I was looking, a light wreath of white smoke curled away from his gun, from which I was too far to hear the report. Nearer, and between me and the hills, toward which they were directing the............
