"Then perhaps you will be good enough to explain your meaning?"

"It was a poor attempt at a jest," said the young man, rather lamely. "Yet it had the truth behind it, in a way. I predict that this is the beginning of one of the biggest mining rushes the world ever saw. We are within one hundred and forty miles of Copah with a practicable railroad; we are within twelve miles with a track which must be made practicable while the band plays. If you discharge your entire engineering corps at this crisis—"

"I beg your pardon," interrupted the president crustily. "I have not asked your force to resign."

"Not meaning to, perhaps," countered the young man, maliciously rejoicing in the hope that he had found one vulnerable link in the president's coat of mail. "But if I go, the entire department will go. Every man in it is my friend, as well as my subordinate; and they know very well that if they shouldn't go, your new chief would fire them and put in his own men."

"Ha!" said the president, straightening up again. "Am I to understand that you are threatening me, Mr. Ford."

"No, indeed; I am only stating a fact. But it is a pretty serious fact. Let us suppose, for the sake of the argument, that my prediction comes true; that within thirty-six or forty-eight hours Saint's Rest is packed with people trying to get to Copah. Your new chief, if you shall have found him, will hardly be in the saddle. When he comes he will have to reorganize the department, break in new men, learn by hard knocks what I have been learning in detail—"

Mr. Colbrith thrust out a thin lip of obstinate determination.

"And if he does, your hypothetical rush will simply have to wait, Mr. Ford. We have the key to the Copah door."

"Don't you fool yourself!" snapped Ford, forgetting his rôle of the humble one for the moment. "The Transcontinental is only forty miles away at Jack's Canyon, with a pretty decent stage road. Long before you can get the extension in shape to carry passengers, or even freight, the other line will be known from Maine to California as the keyholder to this district!"

That shot told. The president was not yet convinced that the Copah boom was real; but there was the chance that it might be—always the chance. And to the over-cautious the taking of chances, however remote, is like the handling of a snake: a thing to inspire creeping horrors.
