HYBRIDS
Although this subject has received far too little attention, yet our limits will only allow us to mention a few facts, of the most practical moment.
Plants hybridize only through their blossoms. This can only occur in plants of similarity, in nature and habits. Squashes and pumpkins planted near each other mix badly, and the poorer will prevail. Varieties of corn mix at considerable distances, by the falling of pollen from the tassel upon the silk of another variety. Watermelons are always ruined by being planted near citrons. The seeds from melons so grown will not produce one good melon. How far watermelons and muskmelons, or squashes with melons, will hybridize, is uncertain. By planting nutmeg muskmelons with the common roughskinned variety, we have produced a kind about half way between them, that was of great excellence. Two kinds of cabbage or turnip seed should never be raised in the same garden. Cabbage and turnip seed raised near together is valueless. In strawberries, different plants are essential to each other, the quality of the fruit being determined by the plant fertilized, and not by the fertilizer. This subject is further treated under articles on different plants.
INARCHING
This is a method of effecting a union of trees or branches, while both retain their hold in the ground. Shave off a little wood from each, and put them together, fitting closely, so that the barks will meet, as in grafting; tie firmly, and cover with wax. When they have got well to growing, cut off the top of the old one, and after a while cut the new one from the ground. When you have a tree that it is difficult to propagate in the usual way, you may transplant it to a thrifty stock. Vigorous branches may by this means be transferred to old, poor-bearing, or slow-growing trees. So also may a tree be prolonged beyond its ordinary age, as the pear on the quince, by inarching young shoots. We can only recommend this to the curious experimenter, who has little else to do.
INSECTS
These are the natural enemies of fruits and plants; and to prevent their depredations requires much care. There is no universal remedy. Birds and young fowls—especially ducks and chickens—are useful in a garden. The ducks must not be kept there too long. They will appropriate a little to their own use, but will save much more for the proprietor. Insects have their peculiar tastes for particular fruits and plants, of which we have treated, under those heads, respectively. Success in many branches of horticulture and pomology, depends upon attention to the habits of insects. The most general remedy is to wash trees or plants with a strong decoction of some offensive herb, or with whale-oil soapsuds. Tobacco is very useful for this purpose.
IRON FILINGS
It has been ascertained by analysis, that iron enters largely into the composition of the pear. Iron filings spread under them, or worked into the soil, increases the growth of pear-trees, and improves the quality of the fruit.
IRRIGATION
This is one of the most important matters, that can engage the attention of agriculturists of the present day. A stream of water that may be caused to flow gently over a field, or different parts of a farm, at pleasure, is a mine of wealth. Plants receive their food from the air and water. We shall discuss this more fully when treating of manures. A poor, porous, sandy, or gravelly soil usually produces a fine crop, in a wet season. That is an addition to the soil of nothing but water. Hence all springs and streams can be turned to great account, on a farm or garden. Watering gardens by hand or with a garden-pump, will often pay better than any other expenditure on the land. Employing a man, in a dry season, to spend his whole time in watering five acres of garden, of berries and vegetables, as cabbages, vines, onions, and potatoes, will pay a very large profit. Strawberries will bear twice as much and twice as long, for daily watering, after they begin to bud for blossoms, until the fruit is gone. It is a necessary caution not to water irregularly, and only occasionally, in a dry season. Better not commence than to leave off, or neglect it in a dry time, before a rain. Read further in our article on "Watering."
LABELS
It is important, on many accounts, to have fruit-trees and shrubs well labelled. Many labels have been invented. We prefer Cole's, as given in his Fruit Book, to any other. Take a piece of sound pine or other soft wood, whittle two sides smooth, leaving one wider than the other, with a sharp corner between them. For one, cut one notch in the edge, and so up to four, four notches for four. For five, cut across the narrow side. For ten cut across the wide side, and a notch for every ten up to forty. For fifty, cut obliquely across the narrow side, and for one hundred cut obliquely across the wide side. Keep the names in a book, with numbers corresponding with the notches or numbers on the labels.
Fasten these to trees, loosely, by a small copper or brass wire. Transported to any distance, exposed to any weather, or buried in the ground, they will not be obliterated. Pieces of sheet lead, tin, or zinc, cut wide at one end, and written on with a sharp awl, and narrow at the other end, to be bent around a limb, will answer a pretty good purpose. Any soft wood, made smooth, and a little white paint applied, and written on with a good pencil, will preserve the mark for a long time. Fasten with small wire. There are many labels, but we know none preferable to the above. By all means make labels accurate and permanent. Otherwise great losses may occur by budding or grafting from wrong varieties.
LANDSCAPE GARDENS
These deserve much more attention than they receive in this country. On most farms land enough is lying waste, to make a picturesque landscape, at a small expense. Trees planted, weeds destroyed, grass cultivated, and paths made, according to the most approved rules of carelessness, would secure this object. With a wealthy man, the omission of such a park about his dwelling is hardly pardonable. Landscape gardening is an extensive subject. We can only give a few of the most general simple rules, that may be practised, without the possession of very large means.
1. Place the house some distance from the main street.
2. Make the carriage-way leading to the house, at least twelve feet wide, and do not allow it to extend in a straight line, but in gentle curves, around clusters of trees and plats of grass, apparently rendering the curves necessary.
3. Have no large trees directly in front of the house.
4. Plant trees of the thickest and greenest foliage near the house, and those of more open tops at a greater distance. Standard pear, and handsome cherry trees, do well planted among the forest trees. Clusters of them, at suitable distances, are not only beautiful, but they bear exceedingly well. They are well protected by the forest trees, and standing alone are injured less by insects.
5. Never set trees in a landscape garden, in straight rows, nor trees of similar size and form together. Nature never does so.
6. Let none of the walks be straight lines, but curves, meandering among trees and grass. If there be any water in the vicinity, let there be an open space, giving a fair view of it from the house. If you have a stream, make rustic bridges over it, the plainer the better. Here and there have rustic arbors. Attached to all this should be three other gardens, one of flowers, another of vegetables, and the third of fruits. These three should never grow together. Fruit-trees ruin vegetables and injure flowers. And flowers in a vegetable garden are mere weeds. A separate plat for each is the correct rule, both for beauty and profit. All this need require but little time and expense. All landholders can, at a moderate cost, live amid scenes of perpetual beauty, while the rich may spend as much money in this way as they choose.
LAYERING
This is a method of propagation, by bending down a branch, and fastening it under the soil, leaving the upper end projecting, until it takes root. Cut half way through the branch so as to raise the top, and fasten it at the point where it is cut, in a trench, with a stick thrust into the ground over it nearly horizontally, or with a stick having a hook made by cutting off a limb. Cover well with soil, and mulch it, and water when dry. This done in the spring, in August the branch will be well rooted, and may be cut away from the parent stalk. This is important in any tree or shrub (like the snowball), difficult to propagate by slips or grafting.
LAYING IN TREES
Dig a trench where water will not stand, and lay the trees in at an angle of forty-five degrees, and cover the roots and lower part, very closely, with earth. In this way they may be well preserved through the winter, if buried so deep that the tap-root will not freeze, which is always injurious to trees that have been removed from their original soil. Such freezing is always destructive to trees out of the ground. Small trees and seedlings may be covered entirely, to be kept through the winter. Put coarse straw manure on the earth, over trees large enough for setting, that are to be preserved heeled in during winter; and straw or corn-fodder over the tops, during the coldest weather, and they will come out perfect in the spring.
If not ready to set out your trees at once, you may preserve them in perfect condition to very late in spring, in this way, by raising them once, to check vegetation, and putting them back, and shading their stems and mulching the roots, after the commencement of warm weather. Trees may thus be preserved in better condition for transplanting than those left in the nursery, and they will make a larger growth the first season.
LEEKS
These are said to be natives of Switzerland. We think this doubtful, as they are an article of daily food in Egypt, and were so highly esteemed there, centuries ago, as to become an object of worship. They are used as a pot-herb, to give a flavor to soups and stews. They are not bulbous, like onions, but have a long stem, which is principally used. They are transplanted very deep, so as to obtain a long white neck. The ends of the roots are to be cut off when transplanted, and they should be set in rows a foot apart, and from four to six inches in the row. There are several varieties, distinguished mainly by the width of the leaves,—the Flanders (or narrow-leafed), the Scotch, and the Broad London.
We know no use of leeks for which onions would not be equally good, and, hence, do not recommend their cultivation.
LEMON
This is the finest acid fruit grown, and belongs to warm climates; but by getting good budded trees from the South, and setting in glass-houses, protected from severe frosts, we may grow lemons in abundance at the North.
By a system of acclimation and protection, we anticipate seeing oranges and other Southern fruits grown at the North as a domestic luxury, and perhaps at a profit for market. The houses necessary for protection may be worth more for other purposes than their cost and care, without interfering with their use for orange and lemon culture.
LETTUCE
The varieties are numerous, and most of them do well on very rich land, well hoed. Only two kinds of summer-lettuce need be cultivated—the ice-head lettuce, and the brown. The ice-head has a very thick and tender leaf, continuing to be excellent up to midsummer, from one sowing; and if not allowed to stand nearer together than six inches, it will produce fine heads. The brown lettuce is very large and very good. There are other, earlier kinds, and many others that form large heads. But we can get the above kinds early, by sowing in a hotbed and transplanting; or by sowing so as to have plants get of considerable size in the fall, and protect by covering in winter. These will be suitable for the table early in the spring. Lettuce does better for transplanting; it forms larger heads than in the original bed, and is a little later. Make the soil very rich with stable-manure. Lettuce is more affected by the quality of the soil than most other vegetables. This is a pleasant and healthy article of food, in spring and early summer.
LICORICE
This is a hardy plant from Southern Europe. The root in substance, or the extracted dried juice, is much used. Needs a deep, rich soil. It is propagated by cuttings of roots set out in deeply-trenched land, in rows three feet apart, and one foot in the row. Small vegetables may be grown among the plants the first year; afterward keep clear of weeds, and manure every autumn. At the end of the third year, after the leaves are dead, take up the roots and dry them thoroughly. This does well at the South. A few roots are sufficient for a family, and the demand will not be sufficient to require its culture very extensively as an article of commerce. The low price of labor in Southern Europe enables them to supply the demand cheaper than can be afforded in this country.
LIME
This is a valuable application to the soil. For wheat it is very important, except on soil containing a large proportion of calcareous matter. Usually air-slaked, and applied as a top-dressing, or plowed or harrowed in, its effects are important. On moist, sour land, producing wild grass, it corrects the acidity, introduces other grass, and prepares the soil for cultivation. On hard, stiff lands, it has a tendency to make them friable, and keep them in a mellow condition, thus saving more than its cost, in the labor of cultivation. Very valuable in a compost heap. So much may be applied as to burn the soil and prove injurious. It will not do as a substitute for everything else. See further on "Manures."
LIME
A fruit resembling the lemon, growing in the same climate, but of smaller size. It is used for the same purposes as the lemon, but is not so valuable. Preserved green, it is highly esteemed. It is cultivated as the orange and lemon, needing the same protection in cold climates. To preserve all these from destruction by insects, wash them in a strong decoction of bitter or offensive herbs, or with whale-oil soap-suds; tobacco is very effectual. These remedies are useful on all fruit-trees.
LOCATION
This is important to everything we cultivate. But, as everything can not have the best location, we should study it with reference to those things most affected by it, especially fruits. Fruits escape late frosts when growing near rills or small brooks. Orchards near the shores of bodies of water—as on Lake Erie about Cleveland, Ohio—bear luxuriantly when all fruit a few miles back is cut off by late frosts. On the summits of hills, fruits escape late frosts, when they are all cut off in the valleys below. On the Ohio river above Cincinnati, peaches are very liable to destruction by late frosts. We have seen them all frozen through in one night, and turned black the next day, in the month of May, after they had grown to the size of marrowfat-peas. One season, when there were no peaches in any other locality within a hundred miles, we knew an orchard, on a Kentucky hill, so high and steep, that it took miles of winding around the hill, to ascend it with a team. Those trees were perfectly loaded with peaches, that sold on the tree at four dollars per bushel, and in Cincinnati market at seven to eight dollars. In Ohio, Kentucky, and Virginia, there are such hills, that may be turned to more valuable account than any of the rest of their land, that are not now considered good for anything—even for sheep-pastures. The same is true in the hilly parts of all the states. Good fruit of some kind will grow on them all, every year.
LOCUST-TREES
It will soon be a great object with American farmers to cultivate locust-trees, in all locations to which they are adapted. Even in this new world, we shall soon be dependent on cultivated timber for fence-posts, railroad-ties, and building purposes. Our native forests are rapidly disappearing, while demand for timber is as rapidly increasing. Probably no other tree is so profitable for cultivation in this country as the locust. It is of rapid growth, and hard and durable, and adapted to many uses. The second-growth locust is not so durable as the native forest-tree, as found in parts of Ohio; but, cut at a suitable age and at the right season of the year, it is as durable as white cedar, and much more valuable. The profits of the culture would be great. An acre of locust-trees fifteen or twenty years old would be worth fifteen hundred or two thousand dollars. The expense of growing it, aside from the use of the land, would be trifling. The grove would afford a good place for fowls, while the blossoms would be nearly equal to white clover for honey. The limbs would make excellent wood, and the ground would need no planting for a second growth. Fortunate will be the men on the prairies of the West, and along the railroads and rivers of the land, who shall early plant fields of locust. The profits of it will greatly exceed the increase in the value of the land.
MANURES
Soils, manures, and preparing the soil—plowing, harrowing, &c.—are the three great subjects in any good agricultural work. We shall treat this subject under the following divisions:—
1. The substances of which manures are composed.
2. Preparation and saving of manures.
3. Time and modes of application.
4. The principles of their action upon plants.
Manures are of two classes—called putrescent and fossil. The putrescent are composed of decayed, or decaying, vegetable and animal substances. The fossil are those dug from the earth, as lime, marl, and gypsum. All vegetable substances not useful for other purposes are valuable for manure. Rotten wood, leaves, straw, and all the vegetable parts of stable manure, and any spoiled vegetables or grain, are all valuable. At the South, their immense quantities of cotton-seed are a mine of wealth, if properly prepared and applied as manure. Animal manures consist of the animal parts of stable manure, dry and liquid, parts of bones, brine, spoiled meat, kitchen slops, soapsuds, and all dead animals. In decaying, these substances all pass through a process of fermentation. Left exposed without suitable care, they become unhealthy and offensive. It is probable that a large share of the diseases suffered in the rural districts are caused by these impurities; and the impossibility of keeping large cities free from these substances is the cause of their increased mortality. In the country, a little timely caution and labor, in removing these substances and regulating their fermentation, would save much sickness; while the labor would pay a larger per-cent. profit than any other performed on the soil. No manures should be allowed to ferment, or decay, without being mixed or covered with enough common earth, sand, peat, or muck, to retain all the gases and exhalations of such putrescence. The smallest quantity that will answer is one load of earth to two of the decaying substances. The proportions reversed would be better: put one bushel of lime to two loads, two quarts of ground plaster, and half a bushel of ashes, and you have the very best compost heap. The following are brief general rules for the preparation of manures. It is always most economical to feed cattle in the stable or under cover, and never have manure exposed to the weather. But if cattle must be fed outdoor, let them be fed in a yard, lowest in the centre, that the liquids and washings may run into the centre, and be absorbed by straw and litter. Put manure on the land, or into heaps for compost, before very warm weather. Always feed sheep under cover, and keep their manure from rain; heap it together with earth in the spring, or apply it to the soil at once. Manure thrown out of a stable should be kept under cover, out of the rain, and not allowed to heat in winter; its best qualities are evaporated by fermentation in the yard. Manures often rained on in winter, or left in large piles without intermixture of earth, lime, plaster, and ashes, will ferment and waste. Construct your stables so that the liquid manure will run into a vat filled with earth; muck is best. Experiments have shown that the liquid manures are at least one sixth better than the solid. A gentleman dug a pit, thirty-six feet square and four feet deep, and walled it in on all sides. He filled his vat from a cultivated field, and so constructed his sewers from the stables adjoining that the urine saturated the whole. He kept fourteen head of cattle there for five months, allowing none but the liquid part of the manure to pass into the vat. He spread forty loads of this on an acre. For ten years he tried equal quantities of this and well rotted and prepared stable-manure, side by side, in the same field, and obtained great crops; but in no stage of their growth could he see that crops on the land manured from the stable were any better than those that had received only the soil from the vat. The latter were quite as good as the former. The contents of his vat manured seven acres, or half an acre to each creature stabled. The result is proof that one cow discharges urine sufficient in five months to manure abundantly half an acre of land. Save the solid manure equally well, and a cow will make manure enough, in five or six months, to increase a crop sufficiently to pay for herself. It is certainly safe to say, that a careful man can make the manure of a cow pay for her body every year. Is not this an important branch of farming operations? Few pay sufficient attention to it. Fowls should roost where their droppings may be mixed with common garden soil or loam. The manure from each fowl, carefully saved and judiciously applied, will pay for its body twice a year. The hogstye may be very productive of manure, one fourth better than that from the stable. Connected with your hogpen, have a yard fifteen feet square for every five hogs; let that yard have no floor. Throw the straw out of their sleeping-room frequently to make room for new; throw into the yard, also, all sorts of weeds, refuse vegetables, corn-husks, peapods, &c.; also the dirt that will naturally accumulate in the backyard of a dwelling, including sawdust, fine chips, cleanings of cellars, scrapings of ditches, and occasionally a load of loam, muck, or clay—and six loads of manure to each hog may be made, that will prove far better than any stable manure; it has been known to produce fifty bushels of corn to the acre, when stable-manure produced but forty bushels. Old wood, brush, and chips, should never be allowed to remain on uncultivated, useless land. Wood throws out the same amount of heat in decaying as it does when consumed as fuel. The action of that heat on the soil is highly beneficial, retaining it long in a mellow state: hence, all wood, too old to be of value for any other purpose, should be put in heaps, covered up till decomposed, and then applied to the soil, as other manures. For potatoes or vines, but especially melons, it is preferable to any other manure. Nothing is so good for muskmelons as old chips from the woodyard. Leaves of fruit and forest trees are also very good; blood and offal of animals, hair, hoofs, bones, horns, refuse feathers, woollen rags, mud from sewers, rivers, roads, swamps, or ponds, turf, ashes, old brine, soapsuds, all kinds of fish, oyster and clam shells—all are valuable, and no part of them should ever be thrown away or wasted; they are all good in compost heaps, or applied directly to the soil. Bones are best ground, but may be used whole, pounded, or chemically dissolved, or mixed with alternate layers of fresh horse-manure, they will be decomposed by the fermentation of the manure (see "Bones"). Perhaps there is as much imprudence in wasting manures as in any part of American domestic economy. One who leaves his stock without care, and so exposed to the weather as to lose half of them and injure the others, is not fit to be a farmer; yet, many waste manure that would produce plants for man and beast, of far more value than the loss of stock complained of, and yet no one notices it—it is a matter of course, exciting no surprise. Wastefulness in a family, if it be of bread, flour, or meat, is considered wicked and impoverishing; while ten times that amount may be wasted in manures, that would enrich the soil, and excite little or no disapprobation. We hope the agricultural periodicals will keep this subject before the people, until these mines of wealth will no longer be neglected or wasted.
Application of Manures is a subject that has been much discussed, and respecting which, intelligent agriculturists differ materially. Some apply them extensively as a top-dressing for grass lands. This does much good, but probably one half of their virtues is lost by washing rains, and by evaporation. A better way is not to keep land down in grass long at a time, and, when under the plow, manure thoroughly. We knew a piece of light land that annually produced half a ton of hay per acre. The owner plowed it up, raised a crop, put a moderate quantity of stable-manure, and ten loads of leached ashes to the acre. We saw it in haying time, the third season after it had been manured and subsoiled and seeded down, and they were then taking fully three tons of timothy hay from an acre, which was the quantity it had yielded three years in succession, without any top-dressing. If a top-dressing of manure is to be applied, harrow the land quite thoroughly, and always apply the manure in the fall—it is worth twice as much as when applied in the spring. The rains and snows of winter cause it to sink into the soil, while the heat of spring and summer evaporate it. A mixture of plaster, lime, ashes, and a very little salt, sowed on meadows, immediately after haying, secures a good growth of feed, much sooner than it will come on other meadows. It also increases, quite considerably, the hay crop of the following season. It is a universal rule not to allow manure to lie long on the surface to which it is applied, before plowing in. Place manure in heaps, as large as will be convenient for spreading, and spread it just before the plow. Never spread manure one day to be plowed in the next. When manuring in the hill, have the planters follow the manure-cart. In manuring potatoes in the hill, drop the potatoes, and put the manure on them and cover at once. In a dry season, the yield will be double that of those planted in the usual way. For fall grains, plow in the manure, just before sowing the seed. This is better than plowing it in under the sod. If the land be not sod land, and you can plow the manure in only deep enough to cover it, and then, just before sowing the seed, plow again very deep, the effect is excellent. Apply manure to land in the fall, or just after harvest, and plow it in, let the land remain till spring, and then plow deep, and you get the best possible effect. On an onion crop, manure does the most good on the surface. On those raised from sets, or on any onions, after they get large enough to give room, put fine manure enough to keep down all weeds, and it will double the crop.
Gypsum is better sowed than in any other way. Mixed with a little lime and salt, or wood-ashes and salt, the effect on corn is better than from either alone. To hoed crops apply these articles twice, and always by sowing, and not by putting it around or upon the hills; the effect is much greater sowed, besides the labor that is saved. In applying guano, do not allow it to come in contact with the plants, as it is apt to destroy them.
It only remains to consider the principles on which manure acts upon soils, and produces growth in plants. The action of manure on the soil, by which it is enabled to retain and appropriate moisture, constitutes its main, if not its whole benefit. It may afford a stimulus to the roots of plants. Even the specific manures, that are supposed to supply organic matter to particular plants, may impart their benefits by their action upon the air and water. Facts are certainly at hand to show that the great and leading benefits of manures are in their control of moisture, and where that control is not needed, plants get a great growth on what we call poor soil. No manures, either fossil or putrescent, afford any considerable food for plants. Vegetation receives its growth mainly from water and from the atmosphere. Facts in support of this theory are abundant.
A trial was made to ascertain whence comes the matter of which a tree is composed. A quantity of kiln-dried earth was weighed and then put into a tight vessel. A willow shrub was also weighed and planted in that earth, and the vessel covered with perforated tin to keep out the dust; for a year and a half it was supplied only with pure water. The tree was then taken out, and found, by weight, to have gained one hundred and sixty pounds. The earth was then kiln-dried, as before, and weighed, and its weight was found to be only two ounces less than it was a year and a half before, when it was deposited there. The tree, then, must have received its growth, not from the soil, but from the water or the atmosphere, or both.
Another fact: take a load of manure, dry it thoroughly, and weigh it. Then moisten it and apply it to the soil, and it will increase the weight of vegetation from ten to thirty or forty times its own weight when dry, and yet most of that manure may still be found in the soil. Hence it can only feed plants in a very limited degree. Its action must be on air and water, or the control it gives the soil over those elements.
It is also matter of common observation that soil well manured, will continue moist for a long time after similar land by its side, but which has not been manured, is dried up. Hard coarse soils dry up very quickly, while soft, mellow, and friable ones will endure a long drought. The gases and moisture generated by the decomposition of manures produce this mellow state. Hence the necessity of having that decomposition take place under the soil, or of plowing in the manure.
