When he went out on day-herd that afternoon he fancied that he was getting into the midst of things and taking his place with the veterans. He would have been filled with resentment had he suspected the truth: that Park carefully eased those first days of his novitiate. That was why none of the night-guarding fell to him until they had left Billings many miles behind them. CHAPTER V. THE STORM The third night he was detailed to stand with Bob MacGregor on the middle guard, which lasts from eleven o'clock until two. The outfit had camped near the head of a long, shallow basin that had a creek running through; down the winding banks of it lay the white-tented camps of seven other trail-herds, the cattle making great brown blotches against the green at sundown. Thurston hoped they would all be there in the morning when the sun came up, so that he could get a picture. “Aw, they'll be miles away by then,” Bob assured him unfeelingly. “By the signs, you can take snap-shots by lightning in another hour. Got your slicker, Bud?” Thurston said he hadn't, and Bob shook his head prophetically. “You'll sure wish yuh had it before yuh hit camp again; when yuh get wise, you'll ride with your slicker behind the cantle, rain or shine. They'll need singing to, to-night.” Thurston prudently kept silent, since he knew nothing whatever about it, and Bob gave him minute directions about riding his rounds, and how to turn a stray animal back into the herd without disturbing the others. The man they relieved met them silently and rode away to camp. Off to the right an animal coughed, and a black shape moved out from the shadows. Bob swung towards it, and the shape melted again into the splotch of shade which was the sleeping herd. He motioned to the left. “Yuh can go that way; and yuh want to sing something, or whistle, so they'll know what yuh are.” His tone was subdued, as it had not been before. He seemed to drift away into the darkness, and soon his voice rose, away across the herd, singing. As he drew nearer Thurston caught the words, at first disjointed and indistinct, then plainer as they met. It was a song he had never heard before, because its first popularity had swept far below his social plane. “She's o-only a bird in a gil-ded cage, A beautiful sight to see-e-e; You may think she seems ha-a-aappy and free from ca-a-re..” The singer passed on and away, and only the high notes floated across to Thurston, who whistled softly under his breath while he listened. Then, as they neared again on the second round, the words came pensively: “Her beauty was so-o-old For an old man's go-o-old, She's a bird in a gilded ca-a-age.”
