Not illustrated. 1908 edition. Excerpt: ...A shortage in the hickory supply is imminent. Virgin hickory, which has hitherto furnished the chief supply, is disappearing rapidly, and there are no foreign sources which can be drawn upon when the home supplies are exhausted. It will soon be necessary, therefore, to depend entirely upon the second growth. The maintenance of the supply is of vital concern, because no satisfactory substitute has as yet been found. Forest owners, with some justice, regard the hickories as inferior trees, but there is one important consideration in their favor; large sizes are not required. With oak, black walnut, black cherry, yellow poplar, and other important hardwood trees, there is a great increase in value with size, because the heartwood is most valuable and timber of large dimensions is needed. But with hickory, the only increase in value with size comes from the increased number or size of the clear billets or strips which can be obtained from a tree. Sapwood is now preferred to heartwood and the younger and faster-grown material is tougher than the older and the slower grown. For most of its uses hickory can be cut when it is 8 or 9 inches in diameter and from 40 to 60 years old, while oak generally must be from 18 to 20 inches in diameter and from 100 to 120 years old. Even hicko, however, can not be cut so early as can catalpa and black locust for fence posts, cottonwood and yellow poplar for pulp, chestnut for ties and poles, and white pine for box boards, and all of these grow faster than hickory. Moreover, the yield of hickory per acre, as is usual with trees which produce a hard, heavy wood, is comparatively low.
