It was Dill who lay and smiled quizzically into the dark and listened to the wide-awake breathing of the man beside him--breathing which betrayed deep emotion held rigidly in check so far as outward movement went. He fell asleep knowing well that the other was lying there wide-eyed and would probably stay so until day. He had had a hard day and had done many things, but what he had done last pleased him best. Now this is a bald, unpolished record of the morning: Billy saw the dawn come, and rose in the perfect silence he had learned from years of sleeping in a tent with tired men, and of having to get up at all hours and take his turn at night-guarding; for tired, sleeping cowboys do not like to be disturbed unnecessarily, and so they one and all learn speedily the Golden Rule and how to apply it. That is why Dill, always a light sleeper, did not hear Billy go out. Billy did not quite know what he was going to do, but habit bade him first feed and water his horse. After that--well, he did not know. Dill might not have things straight, or he might just be trying to jolly him up a little, or he might be a meddlesome old granny-gossip. What had looked dear and straight, say at three o'clock in the morning, was at day-dawn hazy with doubt. So he led Barney down to the creek behind the hotel, where in that primitive little place they watered their horses. The sun was rising redly, and the hurrying ripples were all tipped with gold, and the sky above a bewildering, tumbled fabric of barbaric coloring. Would the sun rise like that in New Mexico? Billy wondered, and watched the coming of his last day here, where he had lived, had loved, had dreamed dreams and builded castles--and had seen the dreams change to bitterness, and the castles go toppling to ruins. He would like to stay with Dill, for he had grown fond of the lank, whimsical man who was like no one Billy had ever known. He would have stayed even in the face of the change that had come to the range-land--but he could not bear to see the familiar line of low hills which marked the Double-Crank and, farther down, the line-camp, and know that Flora was gone quite away from him into the North. He caught himself back from brooding, and gave a pull at the halter by way of hinting to Barney that he need not drink the creek entirely dry--when suddenly he quivered and stood so still that he scarcely breathed. "Oh, where have you been, Billy boy, Billy boy? Oh, where have you been, charming Billy?" Some one at the top of the creek-bank was singing it; some one with an exceedingly small, shaky little voice that was trying to be daring and mocking and indifferent, and that was none of these things--but only wistful and a bit pathetic.
