"Wal, now, me, I call Louis's hittin' that hoss a plumb miracle!" exclaimed an American engagé, Illinois Joe, so called because he was always talking about the glories of that State. "To my certain knowledge that there is the fust time Louis ever come nigh hittin' what he aimed to kill!"

The men resumed their work, and my uncle went to the camp with us. We unloaded the boss ribs and picketed our horses, Pitamakan rubbing some marrow grease into the wound of his animal. I then told my uncle that I thought that we could not possibly guard the men from sudden surprise by the enemy.

"You will do the best you can, and that is all I ask from you," he answered. "From now on, one of the engagés shall stand guard while the others work, and I will take a turn at it myself. You have meat up there? Take a team and wagon and bring it in."

We had the meat in camp by two o'clock; then my uncle advised us to ride out upon discovery. As Pitamakan's runner would be of no service for some time to come, I borrowed Is-spai-u and let him have my fast horse. We could, of course, have ridden the scrub horses of the engagés, but did not care to trust our lives to their slow running in case we should be surprised by a war party.

Is-spai-u was a horse with a history. Four summers before, in the spring of 1861, a war party of seven of the Pikuni, led by One Horn, a noted warrior and medicine man, had gone south on a raid with the avowed intention never to turn back until they had penetrated far into the always-summer land and taken fine horses from the Spanish settlers of that country. That meant a journey southward on foot of all of fifteen hundred miles and an absence from us of at least a year. They chose to go on foot because they could thus most surely pass through that long stretch of hostile country without being discovered by the enemy.

Fifty—yes, a hundred—warriors begged One Horn to be allowed to join his party, but he had had a dream in which the Seven Persons, as the constellation of the Great Bear was called, had appeared and advised him what to do, and he would take only six men. Each one of the six was a man of proved valor and intelligence.

The summer passed and the winter. One Horn and his party were to return in the Moon of Full-Grown Leaves, but they came not. With the appearance of the Berries-Ripe Moon they were long overdue, and some said that without doubt their bones were whitening on the sands of the grassless plains far to the south. Still, hoping against hope, the old medicine man prayed on for them at setting of the sun, and all the people prayed with him.

It was in the Moon of Falling Leaves—October—that we in Fort Benton noticed a lone horseman fording the river and wondered who he could be. Then we saw that it was One Horn. He approached the gate, mournfully calling over and over the names of his six companions; and we knew that they were dead, and the women set up a great wailing for them. When he rode slowly into the court we thought that we had never seen so thin and careworn a man; he was just bones covered with wrinkled skin, and across his breast was a tightly drawn bandage of what had evidently been his buffalo-leather leggings.

We were so painfully struck with his forlorn appearance that we did not at first notice the horse he rode; but when he slipped from it and staggered into the outstretched arms of the crying women, Antoine, the stableman, stepped up to it to lead it away, and he cried out, "See, my frien's, dis horse so beautiful!" We almost cried out with him. The animal was shining black and in good flesh, clean-limbed, of powerful build, gentle and proud.

"A thoroughbred, if ever there was one!" said my uncle, who was standing beside me. "Unquestionably of Andalusian stock!"
