the head where he wants it, out of the reach of his horse; a calculation, however, which he will not realize. THE PREPARATION OF THE SOIL for a nursery should be as deep and as thorough as possible, for some things it is best even to trench the ground; but generally, the thorough plowing, with a deep-tiller, or a trench-plow, will be sufficient, and if followed by the subsoil lifter, so much the better. One of the most intelligent horticulturists, and most successful nurserymen in the country, finds that he can produce a better result in depth and fineness of tilth, by using the Double Michigan plow, than he can with the spade. A piece of clover-sod thus plowed in the fall, and subsoiled at the same time, will be in fine order for nursery purposes, after a thorough cross-plowing and harrowing in the following spring. If the land has been under-drained, so much the better. There is little good land that would not be much improved for nursery purposes by tile draining. If manure is to be applied, it may be spread upon the clover-sod before plowing, or it may be thrown upon the plowed ground at once or at any time during the winter, to be worked into the soil by the spring plowing; if composted, it may be spread just before the spring stirring. LAYING OUT.--In laying out the nursery, some taste may be exercised by the planter; the sections and blocks should be distinct, and alleys should be located at convenient distances, so that all parts may be easily accessible with the wagon. The rows should be laid out straight, and they ought to be far enough apart--four feet might be a good average for nursery trees; cuttings and seedlings may, of course, be nearer. The trees should not be set too closely in the rows, one foot apart is plenty close enough for most kinds, and that is little enough room for the development of good lateral branches, or for those which have to remain three or four years before transplanting. For peaches, for dwarf pears, and indeed for any of the varieties that are to be taken from the nursery as maiden trees, a less space may be allowed--say eight inches apart. Apple stocks for budding, or for collar grafting, may be set ten inches apart, and they will have room to make very good plants, even should they remain until two years old.
