Not illustrated. 1914 Excerpt: ...use, such as pulp wood, fence posts, railway ties, telephone poles and piling, saw timber, etc. This condition of size dominates our present market and through this the utilization of timber. 'See Bull. 11 (new series) 191.4, U. S. Dept. Agri. Sterrett: "Fore't Management of Loblolly Pine." 1. In Loblolly or in Lodge Pole enterprises for hewn railway ties the diameters preferred are 12," 13," and 14." If this is the only use for which the timber is grown, and we get as many ties from the 14" tree as from the 17," It is obviously useless to allow the tree to grow to 16" and waste time and use of land for perhaps twenty years (Lodge Pole) or more. This case, especially in slow growing Lodge Pole, illustrates the importance of careful determination of Rotation. If a stand of Lodgepole produces practically as many satisfactory ties at 150 years as at 180 years, to leave this material the extra thirty years would he a loss which, in large operations, would run into a considerable sum. ()n the other hand, if 150 years are required to produce tie timber, then it is useless to discuss shorter Rotations unless it is reasonablv certain that other uses may be expected to change the market. This also illustrates the uncertainty in this determination of Rotation, especially in new countries where market is rapidly changing its requirements and prices. 2. Generally the upper limit is less rigidly fixed, larger timber-means a greater number of uses, but the lower limit is fixed. In spite of all the changes of the past 100 years, a few fundamental facts remain valid today. The consideration of a few principal uses may illustrate this: a. Fuel wood, though used in enormous quantities must be cheap and have local market; it competes wi...
