We walked on with me talking as fast as I could get the words out. I showed father a giant, bushy chestnut which was dominating all the trees around it, and told him how it retarded their growth. On the other hand, the other trees were absorbing nutrition from the ground that would have benefited the chestnut.
"There's a sinful waste of wood here," I said, as we climbed over and around the windfalls and rotting tree-trunks. "The old trees die and are blown down. The amount of rotting wood equals the yearly growth. Now, I want to show you the worst enemies of the trees. Here's a big white oak, a hundred and fifty years old. It's almost dead. See the little holes bored in the bark. They were made by a beetle. Look!"
I swung my hatchet and split off a section of bark. Everywhere in the bark and round the tree ran little dust-filled grooves. I pried out a number of tiny brown beetles, somewhat the shape of a pinching-bug, only very much smaller.
"There! You'd hardly think that that great tree was killed by a lot of little bugs, would you? They girdle the trees and prevent the sap from flowing."
I found an old chestnut which contained nests of the deadly white moths, and explained how it laid its eggs, and how the caterpillars that came from them killed the trees by eating the leaves. I showed how mice and squirrels injured the forest by eating the seeds.
"First I'd cut and sell all the matured and dead timber. Then I'd thin out the spreading trees that want all the light, and the saplings that grow too close together. I'd get rid of the beetles, and try to check the spread of caterpillars. For trees grow twice as fast if they are not choked or diseased.
Then I'd keep planting seeds and shoots in the open places, taking care to favor the species best adapted to the soil, and cutting those that don't grow well. In this way we'll be keeping our forest while doubling its growth and value, and having a yearly income from it."
"Kenneth, I see you're in dead earnest about this business," said my father, slowly. "Before I came out here today I had been looking up the subject, and I believe, with you, that forestry really means the salvation of our country. I think you are really interested, and I've a mind not to oppose you."
"You'll never regret it. I'll learn; I'll work up. Then it's an outdoor life--healthy, free--why! all the boys I've told take to the idea. There's something fine about it." "Forestry it is, then," replied he. "I like the promise of it, and I like your attitude. If you have learned so much while you were camping out here the past few summers it speaks well for you. But why do you want to go to Arizona?"
"Because the best chances are out West. I'd like to get a line on the National Forests there before I go to college. The work will be different; those Western forests are all pine. I've a friend, Dick Leslie, a fellow I used to fish with, who went West and is now a fire ranger in the new National Forest in Arizona--Penetier is the name of it. He has written me several times to come out and spend a while with him in the woods."
"Penetier? Where is that--near what town?"
"Holston. It's a pretty rough country, Dick says; plenty of deer, bears, and lions on his range. So I could hunt some while studying the forests. I think I'd be safe with Dick, even if it is wild out there."
"All right, I'll let you go. When you return we'll see about the college."
Then he surprised me by drawing a letter from his pocket and handing it to me. "My friend, Mr. White, got this letter from the department at Washington. It may be of use to you out there."
So it was settled, and when father drove off homeward Hal and I went back to camp. It would have been hard to say which of us was the more excited.
Hal did a war dance round the campfire. I was glad, however, that he did not have the little twinge of remorse which I experienced, for I had not told him or father all that Dick had written about the wilderness of Penetier. I am afraid my mind was as much occupied with rifles and mustangs as with the study of forestry. But, though the adventure called most strongly to me, I knew I was sincere about the forestry end of it, and I resolved that I would never slight my opportunities. So, smothering conscience, I fell to the delight of making plans. I was for breaking camp at once, but Hal persuaded me to stay one more day. We talked for hours.
Only one thing bothered me. Hal was jolly and glum by turns. He reveled in the plans for my outfit, but he wanted his own chance. A thousand times I had to repeat my promise, and the last thing he said before we slept was:
"Ken, you're going to ring me in next summer!"
