"Of course I want the job, sir," he said. "The only question is whether I'm good enough." "Well, there's only one way to find out," said Mr. Schofield, grimly. "The principal thing to remember is that never, under any circumstances, must you lose your head. Keep cool, and you've got the battle half won. But if you ever let the work get on your nerves, it's all over. You don't remember Dan Maroney? He was before your time. Well, Maroney was one of the best operators we had on the road, a bright fellow, and I finally called him in to take the extra dispatcher's trick. He seemed to pick up the work all right, and I hadn't any doubt he would make a good dispatcher. One night, the regular dispatcher reported sick, and so I sent for Dan. He took off his coat and sat down at the desk, and the dispatcher who was going off duty explained to him how the trains lay and what orders had been issued. Dan seemed to catch on all right, so the other dispatcher put on his coat and went home. About twenty minutes later, I happened into the office, and there was Dan, lying back in his chair, white as a sheet and trembling like a leaf. "'Why, what's the matter, Dan?' I asked. 'Are you sick?' "'No, I ain't sick, Mr. Schofield,' he said, and grinned the ghastliest grin I ever saw on a man's face. 'But I ain't fit for this job. I've lost my nerve.' "And, in fact, he was nearly scared to death. Well, we tried to bolster him up and help him along, but it was no use. He'd lost his nerve, as he said, and he never got it back again. He's agent and operator now at Bluefield, and that's as far as he'll ever get. So whatever you do, don't lost your nerve." "I'll try not to," said Allan. "I've often thought," added Mr. Schofield, "that a dispatcher was a good deal like a lion-tamer. You know, the tamer enters the cage with perfect safety so long as he keeps his beasts under control. But the moment he loses his nerve, they seem to know it, some way, and perhaps he gets out of the cage alive and perhaps he doesn't. If he does, he never dares go back. He's lost his grip on the beasts and they no longer fear him. Well, the railroad is like that. Lose your grip on it, and it's all over; the only thing to do is to get out as quick as you can." "I'm going to do my best," said Allan. "I'll look it right in the eye." "Good. That's the spirit! You will report here for duty to-morrow morning at seven o'clock. I'll send Jones out to Byers in your place." And Allan left the office, resolved that whatever happened, he would keep his nerve. CHAPTER XIX THE FIRST LESSON
