As they rounded the spur of rocks which had made the watch-tower of the sentinel, the full scene burst upon their eyes. There was a wide, sweet space in the valley, made as if for the very purpose of the great rendezvous. A flat of green cottonwoods adjoined the river-bank. "Benches," or natural terraces, of sweet grass rose along the hillside a half-mile away. Hundreds of horses, picketed or hobbled, grazed here and there. Others, favorite steeds of their masters, stood tied at the doors of lodges, in front of which rose long, tufted spears, in the heraldry of that land insignia of their owner's rank. Teepees, a hundred and twoscore, skin tents of the savage tribes and homes also of the whites, were grouped irregularly over a space of more than half a mile. At the doors of many of these, silent Indians sat and smoked. In the wide interspaces of the village were many men, some of them dressed in brown buckskins, others clad more gaudily. These passed to and fro, some on foot, others riding furiously. Animation was in all the air. Shouts, cries, a tumult formed of many factors filled the air. Babel of speech rose from Frenchmen, Spaniards, Canadians, English, Scotch, Irish, and American backwoodsmen, and Indians of half a dozen tribes. Horses, dogs, black-haired and blanketed women, and children of divers colors moved about continually. The gathering was heterogeneous, conglomerate, picturesque, savage. Samuel Parker, missionary to the Oregon tribes, and now come hither to the mountain market of 1835 as knight-errant of the Gospel, pulled up his horse at the edge of the encampment and gazed in sheer amazement. His party--except Whitman, who reined in his horse at his friend's side--passed on and joined the shouting throng. Apparently they conveyed certain news as they rode; for now out of the circling ranks of wild horsemen there swept toward the strangers a group of yelling riders. Long ribbons and waving eagle feathers streamed from the manes and tails of their ponies. Some riders, even of the white men, wore the great war-bonnets of the northern tribes, the long crests of feathers sweeping back upon the croups of the rough-coated steeds they rode. Weapons were in the hands of all. Loud speech and many oaths were on their lips. They might well have disturbed bolder hearts than that of a peaceful missionary. The leader of the approaching band was a man of gigantic stature, more than six inches above the six-feet mark. He was dark of hair and eye; a wide mustache swept back across his face, and his heavy, untrimmed beard, matted and sunburned at the edges, gave him an expression savage and forbidding. Clad in the buckskin of a mountain trapper, none the less this personage affected a certain finery. A brilliant sash encircled his waist, his hat bore a wide plume. At his belt hung pistols, and in his hand was a long rifle. He pulled up his horse squatting, its nose high in air.
