As Duane turned away from the river he felt refreshed. His great strength and endurance had always made fatigue something almost unknown to him. However, tramping on foot day and night was as unusual to him as to any other riders of the Southwest, and it had begun to tell on him. Retracing his steps, he reached the point where he had abruptly come upon the bluff, and here he determined to follow along its base in the other direction until he found a way out or discovered the futility of such effort.
Duane covered ground rapidly. From time to time he paused to listen. But he was always listening, and his eyes were ever roving. This alertness had become second nature with him, so that except in extreme cases of caution he performed it while he pondered his gloomy and fateful situation. Such habit of alertness and thought made time fly swiftly.
By noon he had rounded the wide curve of the brake and was facing south. The bluff had petered out from a high, mountainous wall to a low abutment of rock, but it still held to its steep, rough nature and afforded no crack or slope where quick ascent could have been possible. He pushed on, growing warier as he approached the danger-zone, finding that as he neared the river on this side it was imperative to go deeper into the willows. In the afternoon he reached a point where he could see men pacing to and fro on the bluff. This assured him that whatever place was guarded was one by which he might escape. He headed toward these men and approached to within a hundred paces of the bluff where they were. There were several men and several boys, all armed and, after the manner of Texans, taking their task leisurely. Farther down Duane made out black dots on the horizon of the bluff-line, and these he concluded were more guards stationed at another outlet. Probably all the available men in the district were on duty. Texans took a grim pleasure in such work. Duane remembered that upon several occasions he had served such duty himself.
Duane peered through the branches and studied the lay of the land. For several hundred yards the bluff could be climbed. He took stock of those careless guards. They had rifles, and that made vain any attempt to pass them in daylight. He believed an attempt by night might be successful; and he was swiftly coming to a determination to hide there till dark and then try it, when the sudden yelping of a dog betrayed him to the guards on the bluff.
