“Easy!” Carfax cautioned. “Don’t let your hopes soar too high. Maybe the top vein runs a little thicker at this point than it did in the others. Call it that, anyway, until you’re cocksure.”

As he spoke the power went off. Tregarvon jerked his watch from his pocket and stifled a hard word. It was noon, and the men were knocking off work on the dot, quite as nonchalantly as if the fate of empires were not hanging upon the result of a few more turns of the machinery. Tregarvon tramped across to the tool-house with Carfax, a sudden weariness making his feet heavy as lead.

“That’s the workman of it!” he gritted. “If the world were coming to an end in the next five minutes, they’d stop to eat!”

Carfax permitted himself a subdued chuckle.

“You are beautifully on edge,” he asserted. “A few inches more may mean a lot to you, but it’s all in the day’s work for the men. They’re not going to get rich out of your coal mine.”

They had brought some of Uncle William’s biscuits and cold chicken for the midday snack, and Carfax went to the motor-car, which had been left standing in the wood road, for the basket. When he returned, Tregarvon was pacing back and forth impatiently before the tool-house door, and Rucker was sitting on the step, eating his luncheon. Carfax carried the basket inside, and they made a table of the coil of rope. While they were picking the chicken bones, the mechanician spoke again of a matter that he had mentioned once or twice before.

“I’m beefin’ ag’in about that boiler, Mr. Tregarvon,” he began, between workman mouthfuls of Mrs. Tryon’s corn bread. “She ain’t much, just as I told you at first; and draggin’ her ’round over this mountain hain’t helped her none. She’s leakin’ like a sieve at the fire-box end of her flues, right now.”

“Here’s hoping that this is the last hole we’ll have to drill with it, Billy,” said Tregarvon cheerfully. “I bought it second-hand, and the Chattanooga junk man put one over on me.”

“He sure did,” Rucker returned with a grin. “She’s rotten. Every time the pop-valve goes off it makes me jump. One o’ these days——”

The interruption was a blatant roar from the boiler in question. Rucker had prudently shut the drafts and had left the fire-door open, or he thought he had, but still the pressure had crept up, until now the safety-valve was relieving it. Through the open door of the tool-shack the two at the rope-coil table could see the plant, with the plume of escaping steam rising to the height of the tree-tops. As usual during the noon hour, there was not a man of the gang in sight. Tregarvon had early learned that a part of the country laborer’s reticence expressed itself in a dislike to eat under the boss’s eye. At the stopping of the machinery the drill-gang would scatter in the wood, each man to his fallen log.
