Bob Mason paid no heed to the last remark. The fever had lost interest for him in the storm-clouds he now saw ahead. Hitherto he had not put his thoughts on the matter into concrete form. He had not given actual expression to his fears. There had been so little to guide him. Besides, he had had no sound reason to fear anything, that is no definite reason. It was his work to feel and understand the pulse of the men under him, and it largely depended on the accuracy of his reading whether or not the work under his charge ran smoothly. He had felt for some time that something was wrong, and Betty's story had confirmed his feeling. He was some moments before he answered, but when he did it was with calm decision.

"Organized strike," he said at last.

Tom Chepstow was startled. The words "organized strike" had an unpleasant sound. He suddenly realized the isolation of these hill camps, the lawless nature of the lumber-jacks. He felt that a strike up here in the mountains would be a very different thing from a strike in the heart of civilization, and that was bad enough. The fact that the tone of Mason's pronouncement had suggested no alarm made him curious to hear his views upon the position.

"The reason?" he demanded.

The lumberman shrugged.

"Haven't a notion."

They tramped on in silence for some time, the sound of their footsteps muffled in the fog. The gray was deepening, and, with oncoming night, their surroundings were rapidly becoming more and more obscure. Presently the path opened out into the wide clearing occupied by No. 1 camp. Here shadowy lights were visible in the fog, but beyond that nothing could be seen. Mason paused and glanced carefully about him.

"This fog is useful," he said, with a short laugh. "As we don't want to advertise our presence we'll take to the woods opposite, and work our way round to the far side of the camp."

"Why the far side?"

"The store is that way. And—yes, I think the store is our best plan. Jules Lieberstein is a time-serving ruffian, and will doubtless lend himself to any wildcat scheme of his customers. Besides, this singsong of the boys sounds suggestive to me."
