and whenever it becomes saturated with the same, may be removed, together with the manure and soiled straw, to a pile beneath the covered shed, when a fresh supply of dry muck, enough to replace that which was removed is carried in and the whole is again covered with the cut straw. An occasional sprinkling of plaster (gypsum) is applied both to the litter in the stall and to the manure heap, which prevents any loss of ammonia, and hence all unpleasant odors are avoided. Whenever a forkful of manure is put on the pile, it is immediately covered with muck. Twice each year this is hauled on to the land. Manure thus treated will not waste, either by the leaching out of soluble matter, by the escape of ammonia, or by fire-fanging. And as there is no coarse material, such as long straw or corn stalks mingled with it, it is always in a suitable condition to use. If dry earth or muck cannot be obtained, cut straw or sawdust may be substituted. But earth, being an excellent deodorizer itself, and containing, as it does, much valuable fertilizing matter, is much to be preferred. If artificial fertilizers are used, they may at any time be mixed with the compost heap. Also, when a pig is kept, its pen should be cleaned daily and the litter, mingled with the general pile, will add greatly to its value. Common salt may occasionally be added to the compost heap with advantage, but ashes never, as they tend to liberate the ammonia and thereby cause waste. YARD ROOM AND EXERCISE. It is not necessary to have a large yard connected with the stable, as a cow is seldom inclined to exercise her locomotive powers more than is required to secure her food, and if this is placed before her at suitable times and in sufficient quantity to supply her demands, she will remain perfectly contented in an enclosure twenty feet square. In planning our buildings let us bear in mind that sunlight is essential to perfect health. Therefore we should have the yard on the sunny side of the building. At the same time we should see that there is a shady corner, where the cow may take herself during intense heat. A hint in this direction is sufficient. Nothing can be more cruel than to force any dumb animal to stand exposed to the rays of an August mid-day sun, or where she is tormented nearly to death by flies. Yet we often see just such inhuman neglect on the part of those who should know better.
