Before he left town a half-dozen of the mountain men had asked him, with an obvious attempt to make the question casual, how he liked the Basin, how long he thought his work would keep him there. Each, as he turned away, followed him with that long, speculative, brooding look. Always, heretofore, his relations with these mountain people had been easy, sympathetic and cordial. Now all at once, without reason, they held him at arm's length and regarded him with suspicious if not hostile eyes.

Puzzling over this he rode back up the road past the Power House. Thence issued Oldham to hail him. He pulled up.

"I hear you're estimating the timber in the Basin," said the gray man, with more appearance of disturbance than Bob had ever seen him display.

Bob acknowledged the accuracy of his statement.

"Indeed!" said Oldham, pulling at his clipped moustache, and after a little, "Indeed!" he repeated.

So the news had run ahead of him. Bob began to think the news important, but for some reason at which he could not as yet guess. This conviction was strengthened by the fact that from the two mountain cabins he pa.s.sed on his way to the beginning of the trail, men lounged out to talk with him, and in each case the question, craftily rendered casual, was put to him as to his business in the Basin. Before one of these cabins stood a sweating horse.

"Look here," he demanded of the Carrolls, "why all this interest about our being in the Basin? Every man-jack asks me. What's the point?"

Old man Carroll stroked his long beard.

"Do they so?" he drawled comfortably. "Well, I reckon little things make news, as they say, when you're in a wild country. They ain't been no work done in the Basin for so long that we're all just nat'rally interested; that's all."

He looked Bob tranquilly in the eye with the limpid gaze of innocence before which Bob's scrutiny fell abashed. For a while his suspicions of anything unusual were almost lulled; the countryside _was_ proverbially curious of anything out of the course of events. Then, from a point midway up the steep trail, he just happened to look back, and just happened through an extraordinary combination of openings to catch a glimpse of a rider on the trail. The man was far below. Bob watched a long time, his eye fixed on another opening. Nothing appeared. From somewhere in the canon a coyote shrilled. Another answered him from up the mountain. A moment later Bob again saw the rider through the same opening as before, but this time descending.

"A signal!" he exclaimed, in reference to the coyote howls.

On arriving at the bare rock, he dismounted and hastily looked it over on all sides. Near the stream it had been splashed. A tiny eddy out of reach of the current still held mud in suspension.

On his arrival at camp he found Elliott much interested over discoveries of his own. It seemed that the Easterner had spent the afternoon fishing. At one point, happening to look up, he caught sight of a man surveying him intently from a thicket. As he stared, the man drew back and disappeared.

"I couldn't see him very plainly," said Elliott. "He had a beard and an old gray hat; but that doesn't mean much of course. When I got my nerve up, and had concluded to investigate, I could hardly find a trace of him. He must wear moccasins, I think."

In return Bob detailed his own experiences. The two could make nothing of it all.

"If we were down South I'd say 'moonshiners,'" said Elliott, "but the beautiful objection to that is, that we aren't!"

"It's some mystery to do with the Basin," said Bob, "and the whole countryside is 'on'--except our boys. I don't believe California John knew a thing about it."

"Didn't act so. Question: what possibly could everybody in the mountains be interested in that the Forest Service would object to?"

"Lots of things," replied Bob promptly, "but I don't believe the mountains are unfriendly to us--as a unit. I know Martin isn't, and he was the first one I noticed as particularly worried."

Elliott reflected.

"If he's so friendly, perhaps he was a little uneasy about _us_," he suggested at length. "If somebody doesn't want the Forest Service in this neck of the woods--if that somebody is relying on the fact that we never come down in here farther than the lookout, why then it may not be very healthy here."

"Hadn't thought of that," said Bob. "That looks cheerful. But what's the point? Nine-tenths of this timber is private property anyway. There's certainly no trespa.s.s--sheep, timber or otherwise--on the government land. What in blazes is the point?"

"Give it up; but we'd better wear our guns."

Bob laughed.

"I'd have a healthy show against a man who really wanted to get me with a gun. Presumably he'd be an expert, or he wouldn't be sent."

It was agreed, however, "in view of the unsettled state of the country,"

as Bob gravely characterized the situation, that the young men should stick together in their work.

"There's no use taking chances, of course," Bob summed up, "but there's no sense in making fools of ourselves, either. Lord love you, I don't mind being _haunted_! They can spring as many mysterious apparitions as they please, so long as said apparitions don't take to heaving bricks.

We'd look sweet and lovely, wouldn't we, to go back to headquarters and tell them we'd decided to come in because a bad man with whiskers who'd never been introduced came and looked at us out of the trees."

In pursuance of this determination Bob and Elliott combined forces closely in their next day's work. That this was not a useless precaution early became apparent. As, momentarily separated by a few feet, they pa.s.sed a dense thicket, Bob was startled by a low whistle. He looked up.

Within fifty feet of him, but so far in the shadow as to be indistinguishable, a man peered at him. As he caught Bob's eyes he made a violent gesture whose purport Bob could not guess.

"Did you whistle?" asked Elliott at his elbow. "What's up?"

Bob pointed; but the man had vanished. Where he had stood they found the print of moccasins.

Thrice during the day they were interrupted by this mysterious presence.

On each occasion Bob saw him first. Always he gestured, but whether in warning or threat Bob could not tell. Each time be vanished as though the earth had swallowed him the instant Elliott turned at Bob's exclamation.

"I believe he's crazy!" exclaimed Elliott impatiently.

"I'd think so, too," replied Bob, "if it weren't for the way everybody acted down below. Do you suppose he's trying to warn us out or scare us off?"

"I'm going to take a crack at him next time he shows up," threatened Elliott. "I'm getting sick of this."

"No, you can't do that," warned Bob.

"I'm going to tell him so anyway."

"That's all right."

For this experiment they had not long to await the opportunity.

"Hi, there!" shouted Elliott at the place from which the mysterious apparition had disappeared; "I give you fair warning! Step out and declare yourself peaceably or accept the consequences. If you show yourself again after five minutes are up, I'll open fire!"

The empty forest gave no sign. For an hour nothing happened. Then all at once, when Elliott was entangled in a tiny thicket close at Bob's elbow, the latter was startled by the appearance of the man not ten feet away.

He leaped apparently from below a rounded rock, and now stood in full view of its crown. Bob had time only to catch cognizance of a blue eye and a long beard, to realize that the man was saying something rapidly and in a low voice, when Elliott's six-shooter exploded so near his ear as almost to deafen him. At the report the man toppled backward off the rock.

"Good Lord! You've killed him!" cried Bob.

"I did not; I fired straight up!" panted Elliott, dashing past him.

"Quick! We'll catch him!"

But catch him nor see him again they did not.

Ten minutes later while working in a wide open stretch of forest, they were brought to a stand by the report of a rifle. At the same instant the shock of a bullet threw a shower of dead pine needles and humus over Elliott. Another and another followed, until six had thudded into the soft earth at the young man's feet. He stood quite motionless, and though he went a little pale, his coolness did not desert him. After the sixth shot silence fell abruptly. Elliott stood still for some moments, then moved forward a single step.
