As he lay on the ground near by, after his watch, he liked to listen to the wild and not unmusical calls of the cowboys as they rode round the half-slumbering steers. There was something magical in the strange sound of it under the stars. Now and then a song would float through the clear air. "The days that I was hard up, I never shall forget. The days that I was hard up-- I may be well off yet. In days when I was hard up, And wanted wood and fire, I used to tie my shoes up With little bits of wire." It was a favorite song with the night-herders. One night, early in the round-up, Roosevelt failed satisfactorily to identify the direction in which he was to go in order to reach the night-herd. It was a pitch-dark night, and he wandered about in it for hours on end, finding the cattle at last only when the sun rose. He was greeted with withering scorn by the injured cowpuncher who had been obliged to stand double guard because Roosevelt had failed to relieve him. Sixteen hours of work left little time for social diversions, but even when they were full of sleep the cowboys would draw up around the camp-fire, to smoke and sing and "swap yarns" for an hour. There were only three musical instruments in the length and breadth of the Bad Lands, the Langs' piano, a violin which "Fiddling Joe" played at the dances over Bill Williams's saloon, and Howard Eaton's banjo. The banjo traveled in state in the mess-wagon of the "Custer Trail," and hour on hour, about the camp-fire on the round-up, Eaton would play to the dreamy delight of the weary men. The leading spirit of those evenings was Bill Dantz, who knew a hundred songs by heart, and could spin an actual happening into a yarn so thrilling and so elaborate in every detail that no one could tell precisely where the foundation of fact ended and the Arabian dome and minaret of iridescent fancy began.
