they crossed a singing brook, shaded with willows and cottonwoods, with fragrant bay and alders, only to clamber out again to the sunny steeps.

Now Bob remembered and pieced together the whole. Baker had been bragging that he intended to pay nothing to the Government for his water power. Bob could almost remember the very words. ""They've swiped about everything in sight for these pestiferous reserves,'" he murmured to himself, "but they encourage the honest prospector. Oldham's got the whole matter and so on, in the unfolding of the very scheme by which these acres had been acquired. "Near headwaters," he had said; and that statement, combined with the fact that nothing had occurred to stir indistinct memories, had kept Bob in the dark. At the time "near headwaters" had meant to him the tract of yellow pine near the head of Sycamore Creek. So he had dismissed the matter. Now he saw clearly that a liberal construction could very well name the Basin as the headwaters of the drainage system from which Sycamore Creek drew, if not its source, at least its main volume of water. He exclaimed aloud in disgust at his stupidity; which, nevertheless, as all students of psychology know, typified a very common though curious phenomenon in the mental world. Suddenly he sat up straight in his saddle. Here, should Baker and the Modoc Mining Company prove to be one and the same, was the evidence of fraudulent intent! Would his word suffice? Painfully reconstructing the half-forgotten picture, he finally placed the burly figure of Welton. Welton was there too. His corroboration would make the testimony irrefutable.

Certainties now rushed to Bob's mind in flocks. If he had been stupid in the matter, it was evident that Baker and Oldham had not. The fight in Durham was now explained. All the demagogic arousing of the populace, the heavy guns brought to bear in the newspaper world, the pressure exerted through political levers, even the con

certed attacks on the Service from the floors of Congress traced, by no great stretch of probabilities, to the efforts of the Power Company to stop investigation before it should reach their stealings. That, as California John had said, was the first defence. If all investigation could be called off, naturally Baker was safe. Now that he realized the investigation must, in the natural course of events, come to his holdings, what would be his second line?

Of course, he knew that Bob possessed the only testimony that could seriously damage him. Even Thorne's optimism had realized the difficulties of pressing to a conviction against such powerful interests without some evidence of a fraudulent intent. Could it be that the presence of this Saleratus Bill in company with Oldham meant that Baker was contemplating so sinister a removal of damaging testimony?

A moment's thought disabused him of this notion, however. Baker was not the man to resort to violence of this sort; or at least he would not do so before exhausting all other means. Bob had been, in a way, the capitalist's friend. Surely, before turning a gun man loose, Baker would have found out definitely whether, in the first place, Bob was inclined to push the case; and secondly, whether he could not be persuaded to refrain from introducing his personal testimony. The longer Bob looked at the state of affairs, the more fantastic seemed the hypothesis that the gun man had been brought into the country for such a purpose.

"Why do you suppose Oldham is up there with this Saleratus Bill?" he asked Ware at length.

"Search me!"

"Is Bill good for anything beside gun work?"

"Well," said Ware, judicially, "he sure drinks without an effort."

"I don't believe Oldham is interested in the liquor famine," laughed Bob. "Anything else?"

"They may be after deer," acknowledged Ware, reluctantly, "though I hate to think that rattlesnake is out for anything legitimate. I will say he's a good hunter; and an Ar trailer."

"Oh, he's a good trailer, is he?" said Bob. "Well, I rather suspected you'd say that. Now I know why they're up there; they want to figure out from the signs we've left just what we've been up to."

"That's easy done," remarked Ware.

This explanation fitted. Bob had been in the Basin before, but on the business of estimating government timber. Baker knew this. Now that the Forest officer had gone in for a second time, it might be possible that he was doing the same thing; or it might be equally possible that he was engaged in an investigation of Baker's own property. This the power man had decided to find out. Therefore he had sent in, with his land man, an individual expert at deducing from the half-obliterated marks of human occupation the activities that had left them. That Oldham and his sinister companion had encountered the Forest men was a sheer accident due to miscalculation.

Having worked this out to his own satisfaction, Bob knew what next to expect. Baker must interview him. Bob was sure the young man would take his own time to the matter, for naturally it would not do to make the fact of such a meeting too public. Accordingly he submitted his report to Thorne, and went on about his further investigations, certain that sooner or later he would again see the prime mover of all these dubious activities.

He was not in the least surprised, therefore, to look up when riding one day along the lonely and rugged trail that cuts across the lower cañon of the River, to see Baker seated on the top of a round boulder. The incongruity, however, brought a smile to his lips. The sight of the round, smooth face, the humorous eyes, and the stout, city-fed figure of this very urhan individual on a rock in a howling

wilderness, with the eternal mountains for a background, was inexpressibly comical.

"Hullo, merry sunshine!" called Baker, waving his hand as soon as he was certain Bob had seen him. "Welcome to our thriving little hamlet."

"Hullo, Baker," said Bob; "what are you doing 'way off here?"

"Just drifting down the Grand Canal and listening to the gondoliers; and incidentally, waiting for you. Climb off your horse and come up here and get a tailor-made cigarette."

"I'm on my way over to Spruce Top," said Bob, "and I've got to keep moving."

"Haste not, hump not, hustle not," said Baker, with the air of one quoting a hand-illuminated motto. "It will only get you somewhere. Come, gentle stranger, I would converse with thee; and I've come a long way to do it."

"I live nearer home than this," grinned Bob.

"I wanted to see you in your office," grinned back Baker appreciatively, "and this is strictly business."

Bob dismounted, threw the reins over his horse's head, and ascended to the top of the boulder.

"Fire ahead," said he; "I keep union hours."

U

NION hours suit me," said Baker. "Why work while papa has his health? What I want to know is, how high is the limit on this game anyway?"

"What do you mean?"

"This confounded so-called 'investigation' of yours? In other words, do you intend to get after me?" "As how?"

Baker's shrewd eyes looked at him gravely from out his smiling fat face.

"Modoc Mining Company's lands."

"Then you are the Modoc Mining Company?" asked Bob.

Baker eyed him again.

"Look here, my angel child," said he in a tone of goodhumoured pity, "I can make all that kind of talk in a witness box if necessary. In any case, I didn't come 'way out here to exchange that sort with you. You know perfectly well I'm the Modoc Mining Company, and that I've got a fine body of timber under the mineral act, and all the rest of it. You know all this not only because you've got some sense, but because I told you so before a competent witness. It stands to reason that I don't mind telling you again where there are no witnesses. Now smoke up and join the King's Daughters let's have a heart-to-heart and find out how we stand."

Bob laughed, and Baker, with entirely whole-hearted enjoyment, laughed too.

"You're next on the list," said Bob, "and, personally, I think
