Mr. Van Britt blew his cheeks out until the stubby, cropped mustache bristled like porcupine quills.

"So you've been getting your pointer, too, have you?" he threw in.

Mr. Norcross didn't answer the question directly.

"Put Tarbell on the job, and if he needs help, let him pick his own men," he directed. "We want to know why that boulder tumbled down ahead of Number Seventeen, and I want to see Tarbell's report on it. Keep at it night and day, Upton. The infection is getting into the rank and file and it's spreading like a sickness. You've railroaded long enough to know what that means. If it becomes psychological, we shall have all the trouble we need."

"I know," nodded the superintendent. "I went through a siege of that kind on the Great Southwestern, one winter. It was horrible. Men who had been running trains year in and year out, and never knowing that they had any nerves, went to pieces if you'd snap your fingers at them."

"That's it," said the boss. "We don't want to fall into that ditch. Things are quite bad enough, as they are."

This ended it for the time. The Petrolite Canyon wreck was picked up, the track was cleared, and once more our trains were moving on time. But anybody could see that the entire Short Line had a case of "nerves." Kirgan, Kirgan the cold-blooded, showed it one afternoon when I went over to his office to return a bunch of blue-prints sent in for the boss's approval. The big master-mechanic had a round-house foreman "on the carpet" and was harrying him like the dickens for letting an engine go out with one of her truck safety chains hanging loose.

Ever since we had gone together on the rescue run to Timber Mountain, Mart and I had been sort of chummy, and after the foreman had gone away with his foot in his hand, I joshed Kirgan a little about the way he had hammered the round-house man.

"Maybe I did, Jimmie," he said, half as if he were already sorry for the cussing out. "But the shape we're getting into is enough to make an angel bawl. Why, Great Moses! a crew can't take an engine out here in the yard to do a common job o' switchin' without breakin' something 'r hurtin' somebody!"

"Bad medicine," I told him. "It's worrying the bosses, too. What's doing it, Mart?"
