"Well, no," admitted Wilbur frankly, "I don't quite see how."
"A forest is made up of a lot of different kind of trees, isn't it, just as a school is made up of a lot of boys? And each of these trees has an individuality, just in the same way that each boy has an individuality. That, of course, is easy to see. But what is more important, and much less known, is that just as the school as a whole gets to have a certain standard, so does the forest as a whole."
"That seems queer," remarked Fred.
"Perhaps it does, but it's true none the less. In many schools there are some boys bigger than others, but who are not good for as much, and they're always picking at the others and crowding them down. In the same way in a forest there are always some worthless trees, trying to crowd out the ones which are of more value. As the trees of better value are always sought for their timber, that gives the worthless stuff a good chance to get ahead. One of the duties of a Forester, looking after his section of the forest, is to see that every possible chance is given to the good over the bad."
"It's really like having people to deal with!" cried Fred in surprise. "It sounds as if a tree were some kind of a human being."
"There are lots of people," said the Chief Forester, "who think of trees and speak of trees just exactly as if they were people like themselves. And it isn't even only the growing of the right kind of trees, but there are lots of ways of handling them under different conditions and at different ages. Thus, a Forester must be able to make his trees grow in height up to a certain stage, then stop their further growth upwards and make them put on diameter."
"But how can you get a tree to grow in a certain way?" asked Fred in utter amazement.
"Get Loyle here to tell you all about it. I suppose you learned that at the Ranger School, didn't you?" he added, turning to the younger boy.
"Yes, sir. We had a very interesting course in silviculture."
"But just to give you a rough idea, Fred," continued the Forester, "you know that some trees need a lot of light. Consequently, if a number of young trees are left fairly close together, they will all grow up straight as fast as they can, without putting out any branches near the bottom, and all their growth will be of height."
