Bob took his examinations, passed successfully, and was at once appointed as ranger. Thorne had no intention of neglecting the young man's ability. After his arduous apprenticeship at all sorts of labour, Bob found himself specializing. This, he discovered, was becoming more and more the tendency in the personnel of the Service. Jack Pollock already was being sent far afield, looking into grazing conditions, reporting on the state of the range, the advisable number of cattle, the trespass cases. He had a natural aptitude for that sort of thing. Ware, on the other hand, developed into a mighty builder. Nothing pleased him more than to discover new ways through the country, to open them up, to blast and dig and construct his trails, to nose out bridge sites and on them to build spans hewn from the material at hand. He made himself a set of stencils and with them signed all the forks of the trails, so that a stranger could follow the routes. Always he painstakingly added the letters U.S.F.S. to indicate that these works had been done by his beloved Service. Charley Morton was the fire chief--though any and all took a hand at that when occasion arose. He could, as California John expressed it, run a fire out on a rocky point and lose it there better than any other man on the force. Ross Fletcher was the best policeman. He knew the mountains, their infinite labyrinths, better than any other; and he could guess the location of sheep where another might have searched all summer.

Though each and every man was kept busy enough, and to spare, on all the varied business inseparable from the activities of a National Forest, nevertheless Thorne knew enough to avail himself of these especial gifts and likings. So, early in the summer he called in Bob and Elliott.

"Now," he told them, "we have plenty of work to do, and you boys must buckle into it as you see fit. But this is what I want you to keep in the back of your mind: someday the National Forests are going to supply a great part of the timber in the country. It's too early yet. There's too much private timber standing, which can be cut without restriction. But when that is largely reduced, Uncle Sam will be going into the lumber business on a big scale. Even now we will be selling a few shake trees, and some small lots, and occasionally a bigger piece to some of the lumbermen who own adjoining timber. We've got to know what we have to sell. For instance, there's eighty acres in there surrounded by Welton's timber. When he comes to cut, it might pay us and him to sell the ripe trees off that eighty."

"I doubt if he'd think it would pay," Bob interposed.

"He might. I think the Chief will ease up a little on cutting restrictions before long. You've simply got to over-emphasize a matter at first to make it carry."

"You mean----?"

"I mean--this is only my private opinion, you understand--that lumbering has been done so wastefully and badly that it has been necessary, merely as education, to go to the other extreme. We've insisted on chopping and piling the tops like cordwood, and cutting up the down trunks of trees, and generally 'parking' the forest simply to get the idea into people's heads. They'd never thought of such things before. I don't believe it's necessary to go to such extremes, practically; and I don't believe the Service will demand it when it comes actually to do business."

Elliott and Bob looked at each other a little astonished.

"Mind you, I don't talk this way outside; and I don't want you to do so," pursued Thorne. "But when you come right down to it, all that's necessary is to prevent fire from running--and, of course, to leave a few seed-trees. Yo' can keep fire from running just as well by piling the debris 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," Thorpe 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 horse............
