His apparent idleness did not prevent him from investigating in his painstaking manner each rumor as it took form. This was the reason why, when finally the formation of a genuine train was undertaken by three of the specialists known as scouts, Michaïl Lafond was one of the earliest to know of it, and one of the first to apply for admission. He owned four strong little horses of mustang stock, and a light, two-wheeled wagon of the bob-tailed type. Most of his life had been spent in the great Northern wilderness. He was expert in his own kind of woodcraft, accustomed to hardships, and a good shot. In every respect he knew himself fitted to become a member of such an expedition as the present. He had no doubt of his acceptance. When he realized that at last his waiting was ended, he saddled one of his horses, and rode three miles out on the lonely prairie, where he jumped up and down, shook his fists in the air, and screamed with delight. This was the half-breed of it. Impassibility may be stupid or intensely nervous. Then, all a-tremble, he rode back to where the three specialists in question were camped, just on the border of the town, and proffered his formal application. The three to whom he addressed himself were practically at the head of their profession. It was not a profession of easy access, but one to which only a long and dangerous apprenticeship gave admittance. Its members were men who had lived their lives on the frontier, either as express riders, hunters, trappers, army scouts, or as members of the Indian tribes themselves. They were a hardy, bold, self-reliant race, equal to all emergencies, and exacting from the men in their charge the most implicit obedience. To their wonderful resourcefulness is due the fact that so many comparatively weak forces were enabled to penetrate in safety a hostile country teeming with the most treacherous and wily foes. As with all crafts, they had their big men--the masters, as it were--whose deeds they emulated, whose feats of skill and divination they spoke of with awe, whose names they worshipped. Of such were Kit Carson, Wild Bill, Jim Clarke, Buffalo Bill, Slade, and the three men with whom we have to deal--Jim Buckley, Alfred, and Billy Knapp. Billy Knapp was dark, tall, broad-shouldered, long-haired, wearing a bristly mustache and goatee. A stranger might have remarked his frowning, beetling brow with a little uneasiness, but would have taken heart from the energetic kindliness of the eyes beneath. In fact, eager, autocratic energy was the dominant note in Billy's character. He succeeded because this energy carried him through--with some to spare.
