DRAINING WET LANDS.Beforemany years there will be thousands of acres pierced with drains. But the inducements to it which make it wise in England and New England do not yet, generally, exist in the West. The expense of draining one acre would buy two. Many farmers have already more arable land than they can till to advantage. Land redeemed from slough would not pay for itself in many years.But although a general introduction of draining would not be wise, there are many cases in which, to a limited extent, it should be practised. Lands lying near to cities are sufficiently valuable, and the market for farming products sure enough, to justify the reclaiming of wet pieces of land. On small farms of forty and eighty acres, surrounded by high-priced lands, not easily procured for enlarging his farm if the owner should wish it, draining might be employed with advantage. A man with asmallfarm canaffordexpenses for high cultivation which would break alargefarmer.Some times a large meadow or arable field is marred by a wet slash through the middle of it; a farmer would not begrudge the labor of draining for the sake of having his favorite field without a blemish. Sometimes farms are intersected by wet lands, which make the passage from one part of the farm to another difficult at all times, and almost impassable at some seasons of the year. Draining might be resorted to in such a case, not so much for the sake of the land reclaimed, as for the convenience of the whole farm.We know pieces of wet, peaty meadow land lying close by the farm-house, the only drawback to the beauty of the place. A good farmer would wish to recover such a spot for the same reason that he would prefer a handsome house to a homely one—a fine horse over a coarse-looking animal—a sightly fence, rather than a clumsy one. There is much strong land—but high, flat, and cold—which is wet through all the spring, resisting seed till long after other portions of the farm are at work, and which would, but for this backwardness, be regarded as the best land. If without great expense, such land could be cured, few farmers would mind the trouble or labor.There are three kinds of draining which may be employed according to circumstances—subsoil-plowing, furrow-draining and ditch-draining. When a soil is underbound by a compact, impervioussubsoil, all the rain or melting snow is retained in the soil until it canexhaleand evaporate. For the subsoil acts like a water-tight floor, or the bottom of a tub. Subsoil-plowing, by thoroughly working through this under crust, gives a downward passage to the moisture; water sinks as it does in sandy loams. Nor will such treatment be less useful to prevent the injury of summer drought; for the depth of soil affords a harbor for roots from whence they can draw moisture when the top-soil is dry as ashes.But there is a limit put to this treatment by the amount of clay contained in the subsoil. It has been experimentally ascertained in England, that when the soil contains as high as forty-three per cent of alumina (clay) sub-soil-plowing is useless, because the clay sooncoalescesand is as impervious as ever. In such cases, if the land has a slight inclination in any direction, furrow-draining may, in some measure, relieve it. The ground is marked out in lands as for sowing grain and plowed with back-furrows, throwing the earth toward the centre. The rain and snow will run to either side, and flow off by the channels left between each strip. This treatment does not relieve theland, to any great extent, of water contained in it, but acts as a preventive, by carrying off the rain and snow before they are absorbed.
