We shall begin with the ground in wheat or rye stubble, as at the end of our course we propose to leave it. Let the stubble ground be well turned over in the fall, to the depth of, say, six inches. It should not be turned over until a sward of white clover has covered the ground, which is to be produced by giving it a top-dressing of gypsum, in the spring. Under the subject of manures the reasons for this will be explained, when treating of gypsum. In the spring give the ground one or two ploughings more, as the nature of the soil may require, and of the same depth, and let the last ploughing be just before the proper time for planting Indian corn; for this crop, with an intermixture of other plants, is what we propose to begin with. Say, for instance, that the intermixture shall consist of the potato, of the pumpkin, and of the common pumpkin, a third part of each. We propose planting these crops in drills, in preference to hills, from a well founded conviction that in the former method considerably more may be obtained from the ground. Let furrows be run, at a good depth, for the drills, at the distance of about every three and a half feet. In these furrows lay off the shortest and best of the fresh barn dung, at the rate of about 20 wagon loads to the acre. For the drills intended for potatoes the longer sort of barn dung is as good as any other. If the different sorts of barn dung can be applied to the soils most suitable for each, as is mentioned in speaking of manures; this should always be attended to; that is, sheep and horse dung for the moister parts of the land, and cow dung for the drier. As fast as the dung is laid, it should be well covered, by a furrow, moderately deep, thrown over it from each side; but where potatoes are to form the alternate drills, let the seed for these be laid on the dung, previous to covering; and for this purpose, let the potatoes be cut in halves, lengthways, so as to give each about an equal number of eyes, and then wet them and roll them in gypsum before laying them down, which should be at the distances of about 15 inches. The potato drills being thus covered, by the furrows thrown from each side, the same process serves to cover the dung in the other furrows, and thus the beds are formed for planting the other crops in the drill method. Indian corn may be drilled in at one operation by a drill machine for the purpose; the same may be observed of the turnip crop, and probably of the pumpkin; but though attended with more labour, it may usually be expected that they will be drilled in by manual operation. We should advise that the seed in the turnip drills be liberally strewn, in order that if part of the plants be destroyed by the flies, enough may still be left. The corn and pumpkin seed may be dropped at the distances of six inches, and thinned at the first hoeing, so as to have the growing plants of the former about a foot apart, and the latter about 16 inches.
