Agriculture; Soil science; Crops and climate; Agriculture; Pédologie; Agriculture et climat. m I i I i i ! 228 arc now an important article of traffic as manure, and are of great value,—as five bushels are considered to be sufficient manure for an acre of turnips, especially if mixed with a little wood ashes. Every farmer should collect and apply Ixmes. They are very valuable, even after being burned or boiled with potash for soap, because, they still contain their phosphate of lime, though deprived of their animal matter. Where means for grinding bones cannot be obtained, they may be broken into small pieces by the hammer ; they may then be mixed with an equal quantity of earth or ashes, moistened, and left to heat before being put into the drills. For practical illustra- tions of the value of bones, I may refer to Jackson's Agriculture. Among other instances, he mentions, that a dressing of 000 bushels on 24 acres of poor pasture had so improved the grass, as to double the yield of butter; and this effect endured I'or many years. In this case the pasture had been laid down for ten years, and, no doubt, much of its natural phos- phate of lime had been exhausted, to form a constitu- ent in the milk and bones of the cattle that had fed on it. Hair and Hoofs are rich manures, though they decay slowly. Such substances, from tanneries, etc., should be saved, and applied to the land. At the rate of twenty or thirty bushels per acre, they produce marked effects. Giiano is a manure produced by the slow decay of the droppings of sea birds, in dry climates, and is chiefly obtained from islands on the coast of Peru. Peruvian guano formerly containe<l from fifty-six to sixty-six per cent, of ammoniacal salts and organic matter, and from 16 to 28 per cent, of phosphates. 11.
