Half an hour later Ridge found himself in the first army camp he had ever visited, amid a body of men the most heterogeneous but typically American ever gathered together. Millionaire dudes and clubmen from the great Eastern cities fraternized with the wildest representatives of far Western life. Men of every calling and social position, all wearing blue flannel shirts and slouch hats, were here mingled on terms of perfect equality. They were drilling, shooting, skylarking, playing cards, performing incredible feats on horseback, cooking, eating, singing, yelling, and behaving in every respect like a lot of irrepressible schoolboys out for a holiday. Here a red-headed Irish corporal damned the awkwardness of a young Boston swell, fresh from Harvard, who had been detailed as cook in a company kitchen; while, close at hand, a New-Yorker of the bluest blood was washing dishes with the deftness gained from long experience on a New Mexican sheep-ranch.

As Ridge and Rollo passed through one of the canvas-bordered streets of this unique camp, the former suddenly leaped aside with an exclamation of alarm. An unknown beast, fortunately chained, had made a spring at him, with sharp claws barely missing his leg.

"You mustn't mind a little thing like that," laughed Rollo, with the air of one to whom such incidents were of every-day occurrence. "It's only 'Josephine,' a young mountain lion from Arizona, and our regimental mascot. She's very playful."

"So it seems," replied Ridge, "and I suppose I shall learn to like her if I join the regiment; but the introduction was a little startling."

A short distance beyond the camp was gathered a confused group of officers, troopers, men in citizen's dress, some of whom were swart-faced Mexicans, and horses. To this Rollo led the way; and, as the new-comers drew near they saw that for a moment all eyes were directed towards a man engaged in a fierce struggle with a horse. The animal was a beautiful chestnut mare with slender limbs, glossy coat, and superb form. Good as she was to look upon, she was just then exhibiting the spirit of a wild-cat or anything else that is most savage and untamable, and was attempting, with desperate struggles, to throw and kill the man who rode her. He was our recent acquaintance, Silas Pine, bronco-buster from the Bad Lands, who, with clinched teeth and rigid features, was in full practice of his chosen profession.
