This chapter, then, will be more especially devoted to the consideration of the three following subjects:— 1st. On the uses of special manures for corn crops. 2nd. On the quality and quantity of corn to be used for seed. 3rd. On the period for harvesting corn. 1st. _On the Uses of Manures._—It is pretty generally agreed that special manuring for corn, when grown in the ordinary shifting crop system, is positively injurious, and more truly so, if farmyard dung be employed. Still, on our own farm we were over-persuaded to give a dressing of rotted dung to some wheat. As the previous crop, turnips, had all but failed, we yielded on being told that it was a common Dorset custom, but, fortunately, only to the extent of a few acres down the middle of the field, on which part, at harvest, the main of the crop had fallen to the ground, with the affection known as knee-bent. There was plenty of straw, not at all good; but the yield of plump grains can hardly be half of those of the other parts of the field. As a general rule, we have never observed special manuring to be useful except as top-dressings in early spring, at which time soot, or, better still, a mixture of soot and guano, may be sown on most wheat crops to advantage, and more especially where the young plant has been injured by the slug or the wire-worm, as in these cases the lower joint and the winter root are destroyed. If, then, the young plant be at this time stimulated with the mixture as advised, and the crop be afterwards rolled, we supply nutriment just in the form that it can be readily assimilated, the injured plants send out new roots from the second joint, and begin a fresh life, whilst the uninjured ones push out new buds—_stolons_—and all grow the better, because the roller has aided in firmly fixing the plants in the ground. There have been those who would tell us that manure can be best used to wheat by subjecting the seed to various steeps; but we need hardly stop to question the folly of the assertions which from time to time re-appear, both at home and abroad, upon this point. Thus far the subject of manures has been treated as for wheat as a shifting crop; but this crop has been grown year after year on the same soil, and, in some cases, without an apparent diminution in quantity or quality. One instance that came under our own observation was in Gloucestershire, where a cottager had grown wheat on the same plot of ground for thirteen years, and, for aught I know, it may still be continued. Hence the subsoil was _Lias shale_; but it was well drained and cultivated as a garden, the manure employed being the contents of the garden-house.
