Remedies of Mildew.--From the above account of the nature or mildew we may easily perceive that it would be impossible wholly to exterminate the fungous plants which aie the cause of it. But though it cannot be wholly exterminated, yet the power of controlling it remains in the hands of the observant and skillful agriculturist. The conditions of soil and culture, and the healthy or unhealthy state of the wheat plants, upon which the progress of mildew very much depend. may be powerfully modified by the skill and the arts of enlightened husbandy. All soils are subject to mildew, but some yield more readily to it than others. Clay soils offer the trreatest resistance to it, in consequence of their tendency to keep up an equable temperature about the plants, and thus save them from frequent vicissitudes of heat and cold. Calcareous and sandy soils, on the contrary, from their opposite ten dency encourage mildew on the crop s raised upon them, henca the importance of an abundant mixture of clay among a sandy soil, at once improving its texture and lessening the tendency to mildew. Moist and " muggy" weather has been found to be most favorable to the spread of mildew, and although the farmer cannot influence the weather, yet by judicious surface drai...
