At midnight the yell of the savage was heard, and a shower of arrows fell around. They had not ascertained with accuracy the position of the travellers. They dared not approach near enough to see, for in that case they could be seen, and the bullet would certainly strike them. After many random shots, and many unearthly yells, the discomfited savages fled. They dared not await the dawn of the day, when upon the open prairie, their arrows would be powerless weapons against rifles. In all these journeyings, Mr. Carson was so cautious that one not acquainted with his well balanced character, might deem him wanting in courage. Not a tree, a rock, a bush, or any other place where an Indian might hide, escaped his notice. His eye was ever scanning the horizon to see if there were any smoke indicating an Indian's fire, or any flight of crows hovering over a spot where Indians had recently encamped. The ground he was ever watching in search of the pressure of the horse's unshod foot, or of the Indian's moccasin. Colonel Fremont had married the daughter of Missouri's illustrious Senator, Hon. Thomas H. Benton. Mr. Carson, upon his arrival at St. Louis, was taken immediately to Mr. Benton's home, where he was treated with every attention, and where he enjoyed the pleasure of an introduction to the most distinguished men of the city. As in the continuance of his journey he stepped upon the platform of the depot in Washington, Mrs. Fremont was there, with her carriage, to convey him as a guest to her residence. In the crowd landing from the cars, Mrs. Fremont recognized him at once, from the description which her husband had given. Mr. Carson remained in Washington for several weeks, greatly interested in the entirely new world which was open to him there. His reputation had gone before him, and the very best men in our land honored themselves in honoring Christopher Carson. President Polk appointed him Lieutenant in the United States Rifle Corps. He was then directed to return immediately across the continent as bearer of important dispatches. Arriving at Fort Leavenworth, in Kansas, he was there furnished with an escort of fifty soldiers to accompany him across the plain. He reached the eastern declivity of the Rocky mountains without important adventure. Here, at a place called Point of Rocks, he overtook a party of United States Volunteers, under command of Lieutenant Mulony. They were escorting a large train of wagons to New Mexico. They encamped not far from each other. Just before the break of day a band of Comanche Indians made an attack upon the cattle of Mulony's party, and got possession of all the oxen and of twenty-six horses.
