The valuable products of decomposing cotton-seed may be preserved by composting, or mixing with other fertilizers which can absorb or combine with its volatile products. 125. The important object to be accomplished, on every farm or plantation, is the restoration to the soil, in some form or other, of the large amount of valuable mineral matter contained in the seed, and the prevention of its permanent removal to the gradual exhaustion of the land. In Europe, rape-seed and linseed-cake, similar to our cotton-seed oil-cake, are highly esteemed as fertilizers. 126. Animal fertilizers, consisting of the flesh of all dead animals, with the scrapings of tanneries and the offal of slaughter-houses, are among the most stimulating substances used to promote the growth of vegetation. The animal structure contains every element of the plant except silicon, and some portions of the body contain most valuable constituents in a highly concentrated form. The products of decomposition are especially rich in nitrogen. 127. The bones and excrements of animals, among the most powerful and valuable of fertilizers, generally undergo some manipulation, or preparation before being used, which renders them more suitable for immediate use, or more convenient for handling. 128. Raw bones when dried consist chiefly of tricalcium phosphate (common phosphate of lime) and gelatinous matter, in the proportion of about two-thirds of the former to one-third of the latter.
