North of the Potomac, and east of the Ohio, and (I presume) in limited districts elsewhere, rocky, sterile woodlands, costing $2 to $50 per acre according to location, etc., are to-day the cheapest property to be bought in the United States. Even though nothing were done with them but keep out fire and cattle, and let the young trees grow as they will, money can be more profitably and safely invested in lands covered by young timber than in anything else. The parent, who would invest a few thousands for the benefit of children or grandchildren still young, may buy woodlands which will be worth twenty times their present cost within the next twenty years. But better even than this would it be to buy up rocky, craggy, naked hill-sides and eminences which have been pastured to death, and, shutting out cattle inflexibly, scratch these over with plow, mattock, hoe, or pick, as circumstances shall dictate, plant them thickly with Chestnut, Walnut, Hickory, White Oak, and the seeds of Locust and White Pine. I say Locust, though not yet certain that this tree must not be started in garden or nursery-beds and transplanted when two or three years old, so puny and feeble is it at the outset, and so likely to be smothered under leaves or killed out by its more favored neighbors. I have experiments in progress not yet matured, which may shed light on this point before I finish these essays. _Plant thickly_, and of diverse kinds, so as to cover the ground promptly and choke out weeds and shrubs, with full purpose to thin and prune as circumstances shall dictate. Many farmers are averse to planting timber, because (they think) nothing can be realized therefrom for the next twenty or thirty years, which is as long as they expect to live. But this is a grave miscalculation. Let us suppose a rocky, hilly pasture-lot of ten or twenty acres rudely scratched over as I have suggested, and thickly seeded with hickory nuts and white oak acorns only: within five years, it will yield abundantly of hoop poles, though the better, more promising half be left to mature, as they should be; two years later, another and larger crop of hoop-poles may be cut, still sparing the best; and thenceforth a valuable crop of timber may be taken from that land; for, if cut at the proper season, at least two thrifty sprouts will start from every stump; and so that wood will yield a clear income each year while its best trees are steadily growing and maturing. I do not advise restriction to those two species of timber; but I insist that a young plantation of forest-trees may and should yield a clear income in every year after its fourth.
