Agricultural Experiment Station; Agriculture -- New York (State). I486 The Cornell Reading-Courses (called the crown); therefore, it will not have as many leaves and will not grow so fast as it might otherwise do. By removing a few trees from crowded clumps, relieving the best trees from too great competition, these trees can be made to grow much more rapidly. There are, however, two dangers in this thinning. A tree growing in an open position will have more branches and the lumber will therefore be more knotty. In order to avoid this, the tree should not be given too much room until the trunk has cleaned itself of branches high enough to give one or more clear saw logs. In the second place, by letting in sun-. FiG 212.—In making improvement cuttings, cultivate the habit of looking up. This picture was taken with the camera pointing straight up from the ground. A tree has just been removed from the center, and the trees left standing will now have a chance to spread into the space that has just been vacated. The object is to develop as many medium-sized, compact, high' set crowns as possible light and wind the soil may be dried out, and perhaps grass and weeds may have a chance to come in because of the light, without which they cannot grow. The slower growth due to this running wild of the soil may more than offset the more rapid growth due to light. Thinning should not be so severe that the soil will dry up seriously or that grass and weeds can start. Improvement cuttings In order to accomplish the ends that have been explained, improvement cuttings should be made in the Please note that these images are extracted from scanned page images that may have been digitally enhanced for readability - coloration and appearance of these illustrations may not perfectly resemble the
