Into such a country Y.D. had ridden from the South, trailing his little bunch of scrub heifers, in search of grass and water and, it may be, of a new environment. Up through the Milk River country; across the Belly and the Old Man; up and down the valley of the Little Bow, and across the plains as far as the Big Bow he rode in search of the essentials of a ranch headquarters. The first of these is water, the second grass, the third fuel, the fourth shelter. Grass there was everywhere; a fine, short, hairy crop which has the peculiar quality of self-curing in the autumn sunshine and so furnishing a natural, uncut hay for the herds in the winter months. Water there was only where the mountain streams plowed their canyons through the deep subsoil, or at little lakes of surface drainage, or, at rare intervals, at points where pure springs broke forth from the hillsides. Along the river banks dark, crumbling seams exposed coal resources which solved all questions of fuel, and fringes of cottonwood and poplar afforded rough but satisfactory building material. As the rancher sat on his horse on a little knoll which overlooked a landscape leading down on one side to a sheltering bluff by the river, and on the other losing itself on the rim of the heavens, no fairer prospect surely could have met his eye.

And yet he was not entirely satisfied. He was looking for no temporary location, but for a spot where he might drive his claim-stakes deep. That prairie, which stretched under the hot sunshine unbroken to the rim of heaven; that brown grass glowing with an almost phosphorescent light as it curled close to the mother sod;—a careless match, a cigar stub, a bit of gun-wadding, and in an afternoon a million acres of pasture land would carry not enough foliage to feed a gopher.

Y.D. turned in his saddle. Along the far western sky hung the purple draperies of the Rockies. For fifty miles eastward from the mighty range lay the country of the foothills, its great valleys lost to the vision which leapt only from summit to summit. In the clear air the peaks themselves seemed not a dozen miles away, but Y.D. had not ridden cactus, sagebrush and prairie from the Rio Grande to the St. Mary’s for twenty years to be deceived by a so transparent illusion. Far over the plains his eye could trace the dark outline of a trail leading mountainward.

The heifers drowsed lazily in the brown grass. Y.D., shading his eyes the better with his hand, gazed long and thoughtfully at the purple range. Then he spat decisively over his horse’s shoulder and made a strange “cluck” in his throat. The knowing animal at once set out on a trot to stir the lazy heifers into movement, and presently they were trailing slowly up into the foothill country.

Far up, where the trail ahead apparently dropped over the end of the world, a horse and rider hove in view. They came on leisurely, and half an hour elapsed before they met the rancher trailing west.

The stranger was a rancher of fifty, wind-whipped and weather-beaten of countenance. The iron grey of his hair and moustache suggested the iron of the man himself; iron of figure, of muscle, of will.

“‘Day,” he said, affably, coming to a halt a few feet from Y.D. “Trailing into the foothills?”

Y.D. lolled in his saddle. His attitude did not invite conversation, and, on the other hand, intimated no desire to avoid it.

“Maybe,” he said, noncommittally. Then, relaxing somewhat,—“Any water farther up?”

“About eight miles. Sundown should see you there, and there’s a decent spot to camp. You’re a stranger here?” The older man was evidently puzzling over the big “Y.D.” branded on the ribs of the little herd.
