“At Jack Welsh’s house,” answered Allan; “just back of the yards yonder.”

“All right, my friend,” said Jim. “I’ll take the liberty of paying you a call before very long. I only hope you’ll be at home.”

“I surely will, if you’ll let me know when to look for you,” answered Allan, heartily. “But I’ve got some letters here for the master-mechanic—I mustn’t waste any more time.”

“Well!” said Jim, smiling, “I don’t think you’ve been exactly wasting your time—though of course there might be a difference of opinion about that. But there he comes now,” and he nodded toward the tall figure of the master-mechanic, who had heard of the accident and was hastening to investigate it.

Allan handed him his letters, which he thrust absently into his pocket, as he listened with bent head to the foreman’s account of the mishap. Allan did not wait to hear it, but, conscious that the errand was taking longer than it should, hurried on to deliver the other letters. This was accomplished in a very few minutes, and he was soon back again at his desk in the trainmaster’s office.

He spent the next half-hour in sorting the mail which had accumulated there. The trainmaster was busy dictating letters to his stenographer, wading through the mass of correspondence before him with a rapidity born of long experience. Allan never ceased to be astonished at the vast quantity of mail which poured in and out of the office—letters upon every conceivable subject connected with the operation of the road—reports of all sorts, inquiries, complaints, requisitions—all of which had to be carefully attended to if the business of the road was to move smoothly.

There was no end to it. Every train brought a big batch of correspondence, which it was his duty to receive, delivering at the same time to the baggage-master other packets addressed to employees at various points along the road. The road took care of its own mail in this manner, without asking the aid of Uncle Sam, and so escaped a charge for postage which would have made a serious hole in the earnings.

As soon as he had received the mail, Allan would hasten up-stairs to his desk to sort it. Always about him, echoing through the office, rose the clatter of the telegraph instruments. The trainmaster had one at his elbow, the chief-dispatcher another, and in the dispatchers’ office next door three or four more were constantly chattering. It reminded Allan of nothing so much as a chorus of blackbirds.

Often Mr. Schofield would pause in the midst of dictating a letter, open his key and engage in conversation with some one out on the line. And Allan realized that, after all, the pile of letters, huge as it was, represented only a small portion of the road’s business—that by far the greater part of it was transacted by wire. And he determined to master the secrets of telegraphy at the earliest possible moment. It was plainly to be seen that that way, and that way only, lay promotion.
