running and, of course, to leave a few seed-trees. Yor can keep fire from running just as well by piling the débris in isolated heaps, as by chopping it up and stacking it. And it's a lot cheaper."

He leaned forward.

"That's coming," he continued. "Now you, Elliott, have had as thorough a theoretical education as the schools can give you; and you, Orde, have had a lot of practical experience in logging. You ought to make a good pair. Here's a map of the Government holdings hereabouts. What I want is a working plan for every forty, together with a topographical description, an estimate of timber, and a plan for the easiest method of logging it. There's no hurry about it; you can do it when nothing else comes up to take you away. But do it thoroughly, and to the best of your judgment, so I can file your reports for future reference when they are needed."

"Where do you want us to begin?" asked Bob.

"Welton is the only big operator," Thorne pointed out, "so you'd better look over the timber adjoining or surrounded by his. Then the basin and ranges above the Power Company are important. There's a fine body of timber there, but we must cut it with a more than usual attention to water supplies."

This work Bob and Elliott found most congenial. They would start early in the morning, carrying with them their compass on its Jacob's-staff, their chain, their field notes, their maps and their axes. Arrived at the scene of operations, they unsaddled and picketed their horses. Then commenced a search for the "corner," established nearly fifty years before by the dead and gone surveyor, a copy of whose field notes now guided them. This was no easy matter. The field notes described accurately the location, but in fifty years the character of a country may change. Great trees fall, new trees grow up, brush clothes an erstwhile bare hillside, fire denudes a slope, even the rocks and boul

ders shift their places under the coercion of frost or avalanche. The young men separated, shoulder deep in the high brakes and alders of a creek bottom, climbing tiny among great trees on the open slope of a distant hill, clambering busily among austere domes and pinnacles, fading in the cool green depths of the forest. Finally one would shout loudly. The other scrambled across.

"Here we are," Bob said, pointing to the trunk of a huge yellow pine.

On it showed a wrinkle in the bark, only just appreciable.

"Let's see if we can "Small creek

Now we come to the down slope. Here we are! 'Yellow pine 20 in. dia., on line, 50 chains.' Twenty inches! Well, old fellow, you've grown some since! Let's see your compass, Elliott."

Having thus cut the line, they established their course and went due north, spying sharply for the landmarks and old blazes as mentioned in the surveyor's field notes.

When they had gone about the required distance, they began to look for the corner. After some search, Elliott called Bob's attention to a grown-over blaze.

"I guess this is our witness tree," said he.

Without a word Bob began to chop above and below the wrinkle in the bark. After ten minutes careful work, he laid aside a thick slab of wood. The inner surface of this was shiny with pitch. The space from which it had peeled was also coated with the smooth substance. This pitch had filmed over the old blaze, protecting it against the new wood and bark which had gradually grown over it. Thus, although the original blaze had been buried six inches in the living white pine wood, nevertheless the lettering was as clear and sharp as when it had been carved fifty years

before. Furthermore, the same lettering, only reversed and in relief, showed on the thick slab that Bob had peeled away. So the tree had preserved the record in its heart. "Now let's see," said Bob. "This witness bears S 80 W. Let's find another."

This proved to be no great matter. Sighting the given directions from the two, they converged on the corner. This was described by the old surveyor as: "Oak post, 4 in. dia., set in pile of rocks," etc. The pile of rocks was now represented by scattered stones; and the oak post had long since rotted. Bob, however, unearthed a fragment on which ran a single grooved mark. It was like those made by borers in dead limbs. Were it not for one circumstance, the searchers would not have been justified in assuming that it was anything else. But, as Bob pointed out, the passageways made by borers are never straight. The fact that this was so, established indisputably that it had been made by the surveyor's steel "scribe."

Having thus located a corner, it was an easy matter to determine the position of a tract of land. At first hazy in its general configuration and extent, it took definition as the young men progressed with the accurate work of timber estimating. Before they had finished with it, they knew every little hollow, ridge, ravine, rock and tree in it. Out of the whole vast wilderness this one small patch had become thoroughly known.

The work was the most pleasant of any Bob had ever undertaken. It demanded accuracy, good judgment, knowledge. It did not require feverish haste. The surroundings were wonderfully beautiful; and if the men paused in their work, as they often did, the spirit of the woods, which as always had drawn aside from the engrossments of human activity, came closer as with fluttering of wings. Sometimes, nervous and impatient from the busy, tiny clatter of facts and figures and guesses, from the restless shuttleweaving of estimates and plans, Bob looked up suddenly

into a deathless and eternal peace. Like the cool green refreshment of waters it closed over him. When he again came to the surface-world of his occupation, he was rested and slowed down to a respectable patience.

Elliott was good company, interested in the work, wellbred, intelligent, eager to do his share an ideal companion. He and Bob discussed many affairs during their rides to and from the work and during the interims of rest. time went on, and the tracts to be estimated and plotted became more distant, they no longer attempted to return at night to Headquarters. Small meadows offered them resting places for the day or the week. They became expert in taking care of themselves so expeditiously that the process stole little time from their labours. On Saturday afternoon they rode to headquarters to report, and to spend Sunday.

NOWARD the end of the season they had worked well past the main ridge on which were situated Wel

T

ton's operations and the Service Headquarters. Several deep cañons and rocky peaks, by Thorne's instructions, they skipped over as only remotely available as a timber supply. This brought them to the ample circle of a basin, well-timbered, wide, containing an unusual acreage of gently sloping or rolling table-land. Behind this rose the spurs of the Range. A half-hundred streams here had their origin. These converged finally in the Forks, which, leaping and plunging steadily downward from a height of over six thousand feet, was trapped and used again and again to turn the armatures of Baker's dynamos. After serving this purpose at six power houses strung down the contour line of its descent, the water was deflected into wide, deep ditches which forked and forked again until a whole plains province was rendered fertile and productive by irrigation.

All this California John, who rode over to show them some corners, explained to them. They sat on the rim of the basin overlooking it as it lay below them like a green cup.

"You can see the whole of her from here," said California John, "and that's why we use this for fire lookout. It saves a heap of riding, for let me tell you it's a long ways down this bluff. But you bet we keep a close watch on this Basin. It's the most valuable, as a watershed, of any we've got. This is about the only country we've managed to throw a fire-break around yet. It took a lot of time to do it, but it's worth while."
