“Why, Roy, you shore don't savvy the way to break these wild ones,” drawled Las Vegas. “Bo will be eatin' out of my hand in about a week.” Bo's blue eyes expressed an eloquent doubt as to this extraordinary claim. “Good-by, friends,” said Roy, and rode away to disappear in the spruces. Thereupon Bo and Las Vegas forgot Roy, and Dale and Helen, the camp chores to be done, and everything else except themselves. Helen's first wifely duty was to insist that she should and could and would help her husband with the work of cleaning up after the sumptuous supper. Before they had finished a sound startled them. It came from Roy, evidently high on the darkening slope, and was a long, mellow pealing halloo, that rang on the cool air, burst the dreamy silence, and rapped across from slope to slope and cliff to cliff, to lose its power and die away hauntingly in the distant recesses. Dale shook his head as if he did not care to attempt a reply to that beautiful call. Silence once again enfolded the park, and twilight seemed to be born of the air, drifting downward. “Nell, do you miss anythin'?” asked Dale. “No. Nothing in all the world,” she murmured. “I am happier than I ever dared pray to be.” “I don't mean people or things. I mean my pets.” “Ah! I had forgotten.... Milt, where are they?” “Gone back to the wild,” he said. “They had to live in my absence. An' I've been away long.” Just then the brooding silence, with its soft murmur of falling water and faint sigh of wind in the pines, was broken by a piercing scream, high, quivering, like that of a woman in exquisite agony. “That's Tom!” exclaimed Dale. “Oh--I was so--so frightened!” whispered Helen. Bo came running, with Las Vegas at her heels. “Milt, that was your tame cougar,” cried Bo, excitedly. “Oh, I'll never forget him! I'll hear those cries in my dreams!” “Yes, it was Tom,” said Dale, thoughtfully. “But I never heard him cry just like that.” “Oh, call him in!” Dale whistled and called, but Tom did not come. Then the hunter stalked off in the gloom to call from different points under the slope. After a while he returned without the cougar. And at that moment, from far up the dark ravine, drifted down the same wild cry, only changed by distance, strange and tragic in its meaning. “He scented us. He remembers. But he'll never come back,” said Dale.
