"Oh, I'm fit enough, by now," was the ready rejoinder. "It was only the first day that got on my nerves."

There was a rough-and-ready welcome awaiting the chief engineer and his guest when they drew rein before Fitzpatrick's commissary; and a supper of the void-filling sort was quickly set before them in the back room of the contractor's quarters. But there was trouble in the air. Ballard saw that Fitzpatrick was cruelly hampered by the presence of Bigelow; and when the meal was finished he gave the contractor his chance in the privacy of the little cramped pay-office.

"What is it, Bourke?" he asked, when the closed door cut them off from the Forest Service man.

Fitzpatrick was shaking his head. "It's a blood feud now, Mr. Ballard. Gallagher's gang—all Irishmen—went up against four of the colonel's men early this morning. The b'ys took shelter in the ditch, and the cow-punchers tried to run 'em out. Some of our teamsters were armed, and one of the Craigmiles men was killed or wounded—we don't know which: the others picked him up and carried him off."

Ballard's eyes narrowed under his thoughtful frown.

"I've been afraid it would come to that, sooner or later," he said slowly. Then he added: "We ought to be able to stop it. The colonel seems to deprecate the scrapping part of it as much as we do."

Fitzpatrick's exclamation was of impatient disbelief. "Any time he'll hold up his little finger, Mr. Ballard, this monkey-business will go out like a squib fuse in a wet hole! He isn't wanting to stop it."

Ballard became reflective again, and hazarded another guess.

"Perhaps the object-lesson of this morning will have a good effect. A chance shot has figured as a peacemaker before this."

"Don't you believe it's going to work that way this time!" was the earnest protest. "If the Craigmiles outfit doesn't whirl in and shoot up this camp before to-morrow morning, I'm missing my guess."
