None knew better than he the narrowness of the margin between saving and losing the mills. Another minute and all would have been lost. The whole structure was built of resinous pine, than which there is nothing more inflammable. The fire had got an alarming hold even in those few minutes, and for nearly an hour victory and disaster hung in the balance. Nor did Dave relinquish his post while any doubt remained. It was not until the flames were fully under control that he left the lumber-jacks to complete the work.

He was weary—more weary than he knew. It seemed to him that in that brief hour he had gone through a lifetime of struggle, both mental and physical. He was sore in body and soul. This disaster had come at the worst possible time, and, as a result, he saw in it something like a week's delay. The thought was maddening, and his ill humor found vent in the shortness of his manner when Dawson attempted to draw him aside.

"Out with it, man," he exclaimed peevishly.

Dawson hesitated. He noticed for the first time the torn condition of his chief's clothes, and the blood stains on the breast of his shirt. Then he blurted out his thankfulness in a tone that made Dave regret his impatience.

"I'm a'mighty thankful you're safe, boss," he said fervently. Then, after a pause, "But you—you got the racket? You're wise to it?"

Dave shrugged. Reaction had set in. Nothing seemed to matter, the cause or anything. The mill was safe. He cared for nothing else.

"Something broke, I s'pose," he said almost indifferently.

"Sure. Suthin' bust. It bust on purpose. Get it?"

The foreman's face lit furiously as he made his announcement.

Dave turned on him. All his indifference vanished in a twinkling.
