"Why not choose trees farther out in the open?" asked Ed Parmly, "where they would be easier to get at and get out."
"Because, if you will use your eyes, Ed, you'll see that out in the open, the trees taper rapidly from stump to top. I want trees that will yield at least one, and if possible, two logs apiece, with very little taper to them. Otherwise, our house will be lop-sided."
"But I say, Jack, what causes the difference? Why do trees in the thick woods grow so much taller and straighter and of more uniform size than trees out in the open?"
"Because every tree is continually hunting for sunlight and air," answered Jack. "Out in the open, each tree finds these easily and goes to work at once to put out its branches, about ten feet from the ground, and to make itself generally comfortable. But where the trees are crowded close together each has to struggle with all the rest for its share of sunlight and air. They do not waste their energies in putting out branches that they can do without, but just keep on growing straight up in search of the air and sunlight. So you see if you want long sticks you must go into the thick woods for them. Out there in that half open glade there isn't a single tree with a twenty-foot reach before you come to its branches, while the trees I have marked here in the thick woods will give us, most of them two logs apiece twenty-one feet long and with not more than three or four inches difference between their diameters at the butt and their diameters at the extreme upper end. It's a good deal so with men, by the way. Those that must struggle for a chance usually achieve the best results in the end."
By this time the axes were all busy felling the marked trees, and within an hour or so they all lay upon the ground, trimmed of their branches, and cut into the required lengths of twenty-one feet each.
Having felled his share of them, Jack went a little further into the woodlands, and began blocking out great chips from one after another big chestnut tree. Having blocked out these chips, Jack sat down and began to split them, observing the result in each case with care. Presently he satisfied himself and set to work to cut down the giant chestnut whose chip had yielded the best results.
"What's all that for, Jack?" asked the Doctor. "Why did you split up those chips in that way, like a little boy with a new hatchet?"
"I was hunting for some timber that isn't 'brash,'" answered Jack, "to make our clapboards out of."
"What do you mean by 'brash?'"
"Why, some timber splits easily and straight along its grain, while other wood breaks away slantwise across the grain. That last kind is called 'brash,' and, of course, it is of no account for clapboards. See here!" and with that he took up two of the big sample chips and illustrated his meaning by splitting them and showing the Doctor how one of them split straight with the grain, while the other showed no such integrity.
