It was the brightest of May days when the new supervisor of track debarked from the mountain-climbing train at Saint's Rest, stretched his legs gratefully on terra firma, had his first deep lungful of the ozonic air of the high peaks, and found his welcome awaiting him. Ford would have no talk of business until he had taken Frisbie across to the little shack "hotel," and had filled him up on a dinner fresh from the tin; nor, indeed, afterward, until they were smoking comfortably in the boxed-off den in the station building which served as the superintendent's office.

"I've been counting on you, Dick, as you know, ever since this thing threatened to take shape in my head," Ford began. "First, let me ask you: do you happen to know where you could lay hands on three or four good constructing engineers—men you could turn loose absolutely and trust implicitly? I'm putting this up to you because the Plug Mountain exile has taken me a bit out of touch."

"Why—yes," said Frisbie, taking time to call the mental roll. "There are Major Benson and his son Jack—you know 'em both—just in off their job in the Selkirks. Then there is Roy Brissac; he'd be a pretty good man in the field; and Chauncey Leckhard, of my class,—he's got a job in Winnipeg, but he'll come if I ask him to, and he is the best office man I know. But what on top of earth are you driving at, Stuart?"

Ford cleared his pipe of the ash and refilled it.

"I'll go into the details with you a little later. We shall have plenty of time during the next month or six weeks, and, incidentally, a good bit more privacy. The thing I'm trying to figure out will burst like a bubble if it gets itself made public too soon, and"—lowering his voice—"I can't trust my office force here. Savez?"

"I savez nothing as yet," laughed the new supervisor, "but perhaps I shall if you'll tell me what is going to happen in the next month or six weeks."

"I'm coming to that, right now. How would you like to take a hunting trip over on the wilderness side of the range? There are big woods and big game."

Frisbie grinned. He was a little man, with sharp black eyes shaded by the heaviest of black brows, and it was his notion to trim his mustaches and beard after the fashion set by the third Napoleon and imitated faithfully by those who sing the part of Mephistopheles in Faust. Hence, his grin was handsomely diabolic.

"You needn't ask me what I'd like; you just tell me what you want me to do," he rejoined, with clansman loyalty.

"So I will," said Ford, taking the reins of authority. "We leave here to-morrow morning for a trip over the Pass and down the Pannikin on the other side, and if anybody asks you why, you can say that we expect to kill a deer or two, and possibly a bear. Your part of the outsetting, however, is to pack your surveying instruments on the burro saddles so they'll pass for grub-boxes, tent-poles, and the like."

"Call it done," said Frisbie. "But why all this stage play? Can't you anticipate that much without endangering your bubble?"

Ford lowered his voice again.

"I gave you the hint. Penfield, my chief clerk—his desk is just on the other side of that partition—is an ex-main-line man, shoved upon me when I didn't want him. He was General Manager North's stenographer. For reasons which will be apparent to you a little later on, I want to blow my bubble in my own way; or, to change the figure, I'd like to fire the first volley myself."

Frisbie's grin was rather more than less diabolic.

"Then I'd begin by firing Mr. Penfield, himself," he remarked.

"No, you wouldn't," said Ford. "There are going to be obstacles enough in the way without slapping Mr. North in the face as a preliminary. Under the circumstances, he'd take it that way; Penfield would make sure that he took it that way."

It was at this point in the low-toned conference that the ingenious young man in the outer office put down the desk telephone ear-piece long enough to smite with his fist at some air-drawn antagonist. Curiosity was this young man's capital weakness, and he had tinkered the wires of the private telephone system so that the flicking of a switch made him an auditor at any conversation carried on in the private office. He was listening intently and eagerly again when Ford said, still in the same guarded tone:

"No, I can't fire Penfield, and I don't particularly want to. He is a good office man, and loyal to his salt: it's my misfortune that it is Mr. North's salt-cellar, and not mine, that he dips into. Besides, I'd have trouble in replacing him. Saint's Rest isn't exactly the paradise its name implies—for a clean-cut, well-mannered young fellow with social leanings."

"Now, what in the mischief does all that mean?" mused the chief clerk, when Ford and his new track man had gone out. "A month's hunting trip over the range, with the surveying instruments taken along. And last summer Mr. Ford spent a good part of his time over there—also hunting, so he said. Confound it all! I wish I could get into that private drawer of his in the safe. That would tell the story. I wonder if Pacheco couldn't make himself an errand over the Pass in the morning? By George!" slapping his thigh and apostrophizing the superintendent, "I'll just go you once, Mr. Ford, if I lose!"

Now the fruit, of which this little soliloquy was the opening blossom, matured on the second day after Ford and Frisbie had started out on the mysterious hunting trip across the range. Pacheco, the half-breed Mexican who freighted provisions by jack train to the mining-camps on the head waters of the Pannikin, came in to report to the chief clerk.

"Well, 'Checo, what did you find out?" was the curt inquiry.

The half-breed spread his palms.

"W'at I see, I know. Dey'll not gone for hunt much. One day out, dey'll make-a da camp and go for squint t'rough spy-glass, so"—making an imaginary transit telescope of his hands. "Den dey'll measure h-on da groun' and squint some more, so."

Penfield nodded and a gold piece changed hands silently.

"That's all, 'Checo; much obliged. Don't say anything about this over in the camp. Mr. Ford said he was going hunting, and that's what we'll say, if anybody asks us."

That night the chief clerk sent a brief cipher telegram to the general manager at Denver.

It was late in the month of June when Ford and Frisbie, tanned, weathered and as gaunt as pioneers, returned to Saint's Rest; and for those who were curious enough to be interested, there were a couple of bear-skins and one of a mountain lion to make good the ostensible object of the absence.

But the most important trophies of the excursion were two engineers' note-books, well filled with memoranda; and these they did not exhibit. On the contrary, they became a part of the collection of maps, statistics, estimates and private correspondence which Chief Clerk Penfield was so anxious to examine, and which Ford kept under lock and key when he and Frisbie were not poring over some portion of it in the seclusion of the private office.

None the less, Penfield kept his eyes and ears open, and before long he had another detail to report by cipher telegram to the general manager. Ford was evidently preparing for another absence, and from what the chief clerk could overhear, he was led to believe that the pseudo supervisor of track would be left in charge of Plug Mountain affairs.

It was on the day before Ford's departure for Denver that a letter came from General Manager North. Ford read it with a scowl of disapproval and tossed it
