OAKS.
Raising oak-timber, on a large scale, will soon be demanded in this country. In some sections we have immense quantities of native oaks; but they are fast disappearing, and the present expense of transporting the timber, to places where it is needed, is much greater than would be the cost of raising it. A million of acres of oaks ought to be planted within the next five years. A crop of white oak, of only twenty-five years' growth, would be very valuable; and twenty-five or fifty acres, of forty years' growth, would be worth a handsome fortune, especially in the West. On all the bluffs in the West they grow well, and on the prairies they will do even better, after they have been cultivated a few years. The application of a little common salt on rich alluvial soils, is a great advantage in growing timber.
Preserve acorns in moist sand during winter, and plant in the spring, in rows six feet apart, to give opportunity for other crops among them for a year or two, to encourage good cultivation. Plant a foot apart in the row, that, in thinning out, good straight trees may be left; at three or four years old, thin to four feet in the rows; afterward, only remove as appears absolutely necessary. Trim straight and smooth. The question of transplanting is important. Shall we plant thick, as in a nursery, and then transplant, or shall we plant where they are to grow? In fruit-trees, the object is to get a low, full, and spreading top, of horizontal branches, that will bear much fruit. This is eminently promoted by transplanting, root-pruning, and heading-in. But in raising timber, the object is to get trees of long, straight bodies, with the fewest possible low branches. Such are the native trees of the forest. This is best promoted by planting thick, never transplanting, and keeping all the lower limbs well trimmed off. These directions are for raising timber on good tillable land. Such groves may be good for pastures, and for poultry-yards, for a long time. Beside this, we have large areas of rough land, that will not soon be brought into cultivation for other purposes. Fine timber may be grown on such land, with no care but trimming.
