For cheese, the dairy should contain three rooms: one for setting the milk, with suitable boilers, &c.; next, a press-room, in which the cheese should be salted, as given under article Cheese; the third, a store-room. In all climates a cheese-house should be made as tight as possible;—thick stone walls are best; windows should be on two sides, north and west, but not on opposite sides, so as to create a draught: this is no better for cheese or butter, and is always dangerous to the operator. Let all persons who would enjoy good health avoid a draught of air as they would an arrow. If your cheese-house can be shaded on the east, south, and west, by trees, and have only a northern exposure, it will aid you much in guarding against extremes of heat and cold. Windows should be fitted closely, and covered with wire-cloth on the outside, so as to exclude all flies.

A dairy for butter needs but two rooms, and a cool, dry cellar, with windows in north and west. The first room should be for setting and skimming the milk, and the other for churning and working the butter, and scalding and cleaning the utensils. If your milk-room can be a spring-house with stone-floor, and a little water passing over it, you will find it a great benefit. The shade, situation of windows, avoiding a current, &c., should be the same as in the cheese-dairy.

To prevent the taste of turnips or other food of cows in milk and butter, put one quart of hot water into eight quarts of the milk just drawn from the cow, and strain it at once. It has been recently declared, by intelligent farmers, that if you feed the turnips to cows immediately after milking, the next milking, twelve hours after feeding the roots, will be free from their taste or odor. The easiest remedy is the boiling water.

DECLENSION OF FRUITS.

That there are instances of decided decline in the quality of fruits is certain. But on the causes of those changes pomologists do not agree. One theory is, that fruits, like animals and vegetables of former ages, may decline and finally become extinct. Should this theory be established, the declension would be so gradual that a century would make no perceptible change. But we do not credit the theory, even as applied to former geological periods in the history of our globe. The changes of past ages, as revealed in geology, have been brought about, not gradually, but by great convulsions of nature, such as volcanoes, or the deluge, that resulted in the destruction of the old order of things, and in a new creation.

The true theory of this declension of varieties of fruits, is, that it is the result of repeated budding upon unhealthy stocks, and of neglect and improper cultivation. Apply the specific manures—that is, those particularly demanded by a given fruit—prune properly, mulch well, and bud or graft only on healthy seedling stocks of the same kind, and, instead of declension, we may expect our best fruits to improve constantly, in quality and quantity.

DILL.

An herb, native in the south of Europe, and on the Cape of Good Hope. It is grown, particularly at the South, as a medicinal herb. The leaves are sometimes used for culinary purposes; but it is principally cultivated for its sharp aromatic seed, used for flatulence and colic in infants, and put into pickled cucumbers to heighten the flavor. The seeds may be sown early in the spring, or at the time of ripening. A light soil is best. Clear of weeds, and thin in the rows, are the conditions of success.

DRAINS.

Drains are of two kinds—under-drains and surface-drains. The latter are simply open ditches to carry off surface-water, that might otherwise stand long enough to destroy the prospective crop. These are frequently useful along at the foot of hills, when they should be proportioned to the extent of the surface above them. They are also very useful on low, level meadow-lands. Properly constructed, they will reclaim low swamps, and make them excellent land. Millions of acres of land in the United States, as good as any we have, are lying useless, and spreading pestilence around, that by this simple method of ditching might be turned to most profitable account. The direction of these drains should be determined by the shape of the land to be drained by them—straight whenever they will answer the purpose, but crooked when they will do better. On low and very level land, they should be not more than five rods apart; they should be three times as wide at the top as they are at the bottom, and as deep as the width at the top; made so slanting, the sides will not fall in;—they should be so shaped as to allow only a very gentle flow of the water: if it flows too rapidly, it will wash down the sides, and obstruct the ditch, and waste the land. Excavations for under-draining are made in the same way, only the top need not be so much wider than the bottom; it would be a waste of labor in excavating a useless quantity of earth. There are four methods of filling up the ditch, viz., with brush; with small stones thrown in promiscuously; with a throat laid in the bottom and filled with small stones; and with a throat made of tile from the pottery. In all cases, that with which the ditch is filled must not come so near the surface as to be reached by the plow. Brush, put in green and covered with straw or leaves, will answer a good purpose for several years, and may be used where small stones can not easily be obtained. The tile is more expensive than either of the others, and not so good as the stones; it is so tight that the water does not enter it so readily; and if by any chance dirt gets into the throat, it obstructs it, and there is no other channel through which the water can pass off. Small stones thrown in promiscuously serve a good purpose for a long time, if they be covered with straw or cornstalks before the earth is put in. But the best method is to make a throat, six inches square, in the bottom of the drain, laying the large stones over the top of it, and filling in the small stones above, and covering with straw;—the water will find its way into the throat through the numerous openings; and if the throat should ever be filled, the water could still pass off between the small stones above. Such drains will last many years, and add one half to the products of all wet springy land. The earth over the new drain should be six inches higher than the surface of the field, that, when well settled, it may be level. Leave no places open for surface-water to run in; that would soon fill up and ruin a drain. Drains made to carry off spring-water are often useless by being in a wrong location. Springs come out near the foot of rising ground. Just where they come out should be the location of the drain, which would then carry off the water and prevent it from saturating and chilling the soil in the field below. Many persons locate their ditch down in the centre of the wet level below the rise of ground; this is of no use to the surface above, to the point where the water springs. Locate the drain just at the point where the land begins to be unduly wet. On very wet, level land, a small drain may also be needed below the first and main one. The cost of a covered drain as described above will be from fifty to seventy-five cents per rod, and an uncovered one will cost from twenty to thirty cents. When you have low swamps to drain, you can realize more than the cost of draining, by carting the excavations upon other land, or into the barnyard as material for compost. Perhaps no expenditure, on land needing it, pays so well as thorough draining. It is important, for all fruit-orchards on low land, to put a drain through under each row of trees: it is indispensable to cherries, and highly favorable to all other fruits.
