I can scarcely reconcile myself to the common practice of plowing in the manure to the depth that our farmers generally do. This course he had heard advocated for the past twenty years; he was now a believer in surface-manuring. It prevents the surfaces from baking, which is a great benefit The result which follows from the top-dressing of grass lands is sufficient proof of its utility; by this means clover is produced where it never grew before. Surface-manuring he considered the best, as the manurial properties were not placed too far beyond the reach of the plants.
Has not had much experience with mildew this season, in-doors; has observed it out-doors more. Avoid cold currents; mildew occurs most in ungenial weather, causing a check or stagnation to vegetation; attacks diseased, sickly plants more than those of luxuriant growth. Has had no mildew on roses; keeps them in an airy yet moist temperature; thinks them more liable in dry than in damp weather. With graperies I allow no front air, till time to ripen off crop; am not an advocate for much air for grapes, and this at top. With proper precaution there is no fear of mildew. Thinks, on potatoes, it occurs in wet weather, and in dry, hot days, after damp weather. Seeds of fungus seem to grow in damp, and are matured in dry atmosphere. This is not very clear, however.
It is not injurious in damp weather.
