In the course of the next few days Roy rode to and fro over the park trying to sell his windmill to the ranchers. He secured two orders and the tentative promise of others. But he gained no clue as to the place where Dingwell was hidden. His intuition told him that the trail up Chicito Canon would lead him to the captive cattleman. Twice he skirted the dark gash of the ravine at the back of the pasture, but each time his heart failed at the plunge into its unknown dangers. The first time he persuaded himself that he had better make the attempt at night, but when he stood on the brink in the darkness the gulf at his feet looked like a veritable descent into Avernus. If he should be caught down here, his fate would be sealed. What Meldrum and Tighe would do to a spy was not a matter of conjecture. The thought of it brought goose-quills to his flesh and tiny beads of perspiration to his forehead. Still, the peril had to be faced. He decided to go up the canon in the early morning before the travel of the day had begun. The night before he made the venture he prepared an alibi by telling Mrs. Rothgerber that he would not come to breakfast, as he wanted to get an early start for his canvassing. The little German woman bustled about and wrapped up for him a cold lunch to eat at his cabin in the morning. She liked this quiet, good-looking young man whose smile was warm for a woman almost old enough to be his grandmother. It was not often she met any one with the charming deference he showed her. Somehow he reminded her of her own Hans, who had died from the kick of a horse ten years since. Roy slept in broken cat-naps full of fearful dreams, from which he woke in terror under the impression that he was struggling helplessly in the net of a great spider which had the cruel, bloodless face of Tighe. It was three o'clock when he rose and began to dress. He slipped out of the cabin into the wet pasture. His legs were sopping wet from the long grass through which he strode to the edge of the gulch. On a flat boulder he sat shivering in the darkness while he waited for the first gray streaks of light to sift into the dun sky. In the dim dawn he stumbled uncertainly down the trail into the canon, the bottom of which was still black as night from a heavy growth of young aspens that shut out the light. There was a fairly well-worn path leading up the gulch, so that he could grope his way forward slowly. His feet moved reluctantly. It seemed to him that his nerves, his brain, and even his muscles were in revolt against the moral compulsion that drove him on. He could feel his heart beating against his ribs. Every sound startled him. The still darkness took him by the throat. Doggedly he fought against the panic impulse to turn and fly.
