That mysterious warm-air current known as the Chinook wind steals through the depressions of the Rocky Mountains, at certain seasons of the year, from the mild surface of the Pacific, and tempers the severity of the winters in some portions of Montana, Wyoming, and the great West to a degree that renders them milder than many places farther south.

It was early in the month of May, when even in the Middle States it is not often comfortable to remain seated out of doors after the close of day, but Sterry and Whitney found it pleasant to occupy their chairs in front of the building, with no other protection then their own warm garments.

Whitney's wound was doing so well that he expressed himself ashamed to wear his arm in a sling. He freed it from the support, moved it readily about, and declared that after the next morning he would no longer shirk duty.

In one sense, Monteith Sterry was disappointed. He hoped they would be joined by Jennie, from whom he parted earlier in the evening, but he reflected that the hour was late, and she probably felt that her duty was with her sorrowing mother.

"She belongs there," he concluded, "and I respect her for doing her duty."

But she heard the murmur of voices after they had talked a few minutes, and appeared at the outer door, where she greeted her friend and listened with an intensity of interest that may be imagined to his account of his brush with the rustlers. Although she had become accustomed to danger during her life in the West, there could be no mistaking her solicitude for him. She said little, however, and, excusing herself, bade the two good-night.

"I tell you," said her brother, when she was gone, "if you stay, or rather attempt to stay, in this section, Mont, it is suicide—nothing more nor less."

"Well, I know times are likely to be warm, but, hang it, I can't bear the thought of being run out of Wyoming. It's a mighty big State, and there ought to be room enough for me."

"You persist in treating it lightly, but it is no trifling matter; you have been warned; were shot at, when we had our flurry with the rustlers; and, even while attempting to ride across the country, had the narrowest escape of your life—an escape so curious that it couldn't be repeated in a hundred years."

"It's the unexpected that happens."
