"How about Aileen?" he said.

"I'll take that back," said Merritt; "Mrs. McGinnis hasn't gone to diameter growth. But," he continued, "she's good on clear length and has a fine crown."

By which Wilbur readily understood that the lumberman's wife was slight, well-built, and neat, and with heavy hair. The lumberman, mollified by the tribute, returned to his dinner, and the Supervisor continued:

"McGinnis told you that cutting down the best trees available for timber is the most important part of forest work. It's not. The most important thing is keeping the forest at its best. Cutting trees when they have reached their maximum is a most necessary part, and it's a policy that helps to make the forest pay for itself. But the value to the forest lies in its conservation. You know about that?"

"Yes, sir," said the boy; "it's keeping the watersheds from becoming deforested, either by cutting or by fire, and so preventing erosion from taking place."

"I reckon," put in the old Ranger, "thar's another that pleases me still better than either of those."

"And what's that, Rifle-Eye?" asked Merritt.

"It's the plantin'. When I walk along some of the forest nurseries, an' see hundreds and hundreds of little seedlin's all growin' protected like, and bein' cared for just the same as if they was little children, an' when I know that in fifty years time they'll be big fine trees like the one we're sittin' under, I tell you it looks pretty good to me. They're such helpless little things, seedlin's, and they do have such a time to get a start. Nursery's a good name all right. I've been along some of 'em at night, when the moonlight was a shinin' down on them, and they wasn't really no different from children in their little beds."

"I should think," said Wilbur, "that the changing of a forest from one kind of tree to another would be the most interesting. I mean getting rid of the worthless trees and giving the advantage to those that are finer."

"And a few sections west," commented the Supervisor, "you would find that Bellwall, who's the Ranger there, thinks that the most interesting thing in the whole of the forest work is putting an end to the diseases of trees and to the insects that are a danger to them. Another Ranger may be a tree surgeon."
