Читать книгу What I know of farming: - Greeley Horace - Страница 11

Whoever has recently bought, inherited, or otherwise become the owner of a farm, has usually found some part or parts of it devoted to wood; and this, if not in excess, he will mainly preserve, while he studies and plans with a view to the ultimate devotion to timber of just those portions of his land that are best adapted to that use. In locating that timber, I would have him consider these suggestions:

I. Land wisely planted with trees, and fenced so far as need be to keep out cattle, costs nothing. Whatever else you grow involves labor and expenditure; trees grow of their own accord. You may neglect them utterly – may wander over the earth and be absent for ten or twenty years, while your fences decay and your fields are overcropped to exhaustion; even your meadows may be run out by late mowing and close feeding at both ends of the season, till a dozen acres will hardly subsist a span of horses and a cow; but your woods need only to be let alone to insure that their value shall have decidedly increased during your absence. They will richly reward labor and care in thinning, trimming, and transplanting – you may profitably employ in them any time that you can spare them – but they will do very well if simply let alone. And, unlike any other product with which I am acquainted, you may take crop after crop of wood from the same lot, and the soil will be richer and more productive after the last than it was before the first. Whether wholly because their roots permeate and break up the soil during their life and enrich it in their decay, or for diverse reasons, it is certainly true that land – and especially poor land – is enriched by growing upon it a crop of almost any timber, the evergreens possibly excepted. So, should you ever have land that you cannot till to profit, whether because it is too poor, or because you have a sufficiency that is better, you should at once devote it to wood.

II. Your springs and streams will be rendered more equable and enduring by increasing the area and the luxuriance of your timber. They may have become scanty and capricious under a policy of reckless, wholesale destruction of trees; they will be rëenforced and reinvigorated by doubling the area of your woods, while quadrupling the number, and increasing the average size, of your trees.

III. All ravines and steep hill-sides should be devoted to trees. Every acre too rocky to be thoroughly cleared of stone and plowed should be set apart for tree-growing. Wherever the soil will be gullied or washed away by violent rains if under tillage, it should be excluded from cultivation and given up to trees. Men often doubt the profit of heavy manuring; and well they may, if three-fourths of the fertilizers applied are soaked out and swept away by flooding rains or sudden thaws and floated off to some distant sea or bay; but let all that is applied to the soil only remain there till it is carted away in crops, and it will hardly be possible to manure too highly for profit.

IV. Trees, especially evergreens, may be so disposed as to modify agreeably the average temperature of your farm, or at least of the most important parts of it. When I bought my place – or rather the first installment of it – the best spot I could select for a garden lay at the foot of a hill which half surrounded it on the south and east, leaving it exposed to the full sweep of north and north-west winds; so that, though the soil was gravelly and warm, my garden was likely to be cold and backward. To remedy this, I planted four rows of evergreens (Balsam Fir, Pine, Red Cedar, and Hemlock), along a low ridge bounding it on the north, following an inward curve of the ridge at its west end; and those evergreens have in sixteen years grown into very considerable trees, forming a shady, cleanly, inviting bower, or sylvan retreat, daintily carpeted with the fallen leaves of the overhanging firs. I judge that the average temperature of the soil for some yards southward of this wind-break is at least five degrees higher, throughout the growing season, than it formerly was or would now be if these evergreens were swept away; while the aspect of the place is agreeably diversified, and even beautified, by their appearance. I believe it would sell for some hundreds of dollars more with than without that thrifty, growing clump of evergreens.

V. I have already urged, though not strongly enough, that crops, as well as springs, will be improved by keeping the crests of ridges thickly wooded, thus depositing moisture in Winter and Spring, to be slowly yielded to the adjacent slopes during the heat and drouth of Summer. I firmly believe that the slopes of a hill whose crest is heavily wooded will yield larger average crops than slope and crest together would do if both were bare of trees.

VI. The banks of considerable streams, ponds, etc., may often be so planted with trees that these will shade more water than land, to the comfort and satisfaction of the fish, and the protection of those banks from abrasion by floods and rapid currents. Sycamore, Elm, and Willow, do well here; if choice Grape-Vines are set beside and allowed to run over some of them, the effect is good, and the grapes acceptable to man and bird.

VII. Never forget that a good tree grows as thriftily and surely as a poor one. Many a farmer has to-day ten to forty acres of indifferent cord-wood where he might, at a very slight cost, have had instead an equal quantity of choice timber, worth ten times as much. Hickory, Chestnut, and Walnut, while they yield nuts that can be eaten or sold, are worth far more as timber than an equal bulk of Beech, Birch, Hemlock, or Red Oak. Chestnut has more than doubled in value within the last few years, mainly because it has been found excellent for the inside wood-work of dwellings. Locust also seems to be increasing in value. Ten acres of large, thrifty Locust near this City would now buy a pretty good farm; as I presume it would, if located near any of our great cities.

VIII. Where several good varieties of Timber are grown together, some insect or atmospheric trouble may blast one of them, yet leave the residue alive and hearty. And, if all continue thrifty, some may be cut out and sold, leaving others more room to grow and rapidly attain a vigorous maturity.

IX. Wherever timber has become scarce and valuable, a wood-lot should be thinned out, nevermore cleared off, unless it is to be devoted to a different use. It seems to me that destroying a forest because we want timber is like smothering a hive of bees because we want honey.

X. Timber should be cut with intelligent reference to the future. Locust and other valuable trees that it is desirable should throw up shoots from the stump, and rapidly reproduce their kind, should be cut in March or April; while trees that you want to exterminate should be cut in August, so that they may not sprout. There may be exceptions to this rule; but I do not happen to recollect any. Evergreens do not sprout; and I think these should be cut in Winter – at all events, not in Spring, when full of sap and thus prone to rapid decay.

XI. Your plantation will furnish pleasant and profitable employment at almost any season. I doubt that any one in this country has ever yet bestowed so much labor and care on a young forest as it will amply reward. Sow your seeds thickly; begin to thin the young trees when they are a foot high, and to trim them so soon as they are three feet, and you may have thousands thriving on a fertile acre, and pushing their growth upward with a rapidity and to an altitude outrunning all preconception.

XII. Springs and streams will soon appear where none have appeared and endured for generations, when we shall have reclothed the nakedness of the Plains with adequate forests. Rains will become moderately frequent where they are now rare, and confined to the season when they are of least use to the husbandman.

I may have more to say of trees by-and-by, but rest here for the present. The importance of the topic can hardly be overrated.
