seems to be forgotten that chemistry is scarcely half a century old, and that it is but as yesterday that she volunteered her services to agriculture. Nothing is easier than to sneer at the inveterate prejudices that cloud the agricultural mind, and that impede all agricultural progress; but it may be well to remember that chemistry itself was at a comparatively late period associated with alchemy--that its aims were empirical, the chief of them being the discovery of the philosopher's stone, and the transmutation of the baser ores into fine gold. It seems the special province and duty of landowners, who have the leisure and the means, to make experiments; but British farmers, previous to their adoption, are entitled to satisfy themselves that the discoveries of science are readily available by them, and are likely to be profitable. The most enthusiastic chemist will scarcely deny that the discovery of a very condensed animal manure in the islands of the Pacific has contributed more to the prosperity of agriculture than any modern discovery in his favourite science. We write this in the profoundest conviction of the importance of chemistry and the cognate sciences, and of the impetus they will yet give to agricultural progress; but as it is the present fashion to contemn the torpid and immovable understandings of British farmers, it may be well to remind our philosophers that they have been very long of thinking how their philosophy could advance the culture of the soil, or increase the supply of human food--a vulgar consideration, but not to be despised by philosophic sages, who must live like meaner mortals--and that, as yet, they have rather evolved principles, than shown Mr Hodge how he can profitably apply them. Of late, too, a most ridiculous rout has been made about liquid manures; and our urinary land-doctors would persuade us that they could liquify the whole face of the earth into a garden. To such hydropathic empirics we cry, pish! The value of liquid manures is undeniable, as seen in the watered meadows adjoining our cities; and on dairy farms the quantity may be such, that the application of it may not only be expedient, but profitable. When farmers generally, however, are abused for their ignorant neglect and waste of liquid manure, it is necessary to inquire into the justice of the charge. In the first place, it is certain that the litter in the cattle-court, if the court is rightly constructed and situated, will easily absorb all the liquid flowing from the animals in it and in the byres. Suppose the urine were collected as it passed from the animals, and were prevented from permeating and saturating the manure in the court, then, nearly _pro tanto_, the value of the manure would be deteriorated. This seems undeniable. The leakage from cattle-courts, when properly situated, arises exclusively from rain-water; and the overflow is caused by the want of rones to the buildings, and the waste of this diluted liquor
