In selecting a location for a filbert orchard, an open, airy one would probably be preferable to a spot so sheltered as to cause the flowers to appear so early as to be injured by frosts. Furthermore, I would warn cultivators to keep as far away as possible from any hedgerows or plantation of the wild native hazel bushes, for these are always loaded with disease germs that are fatal to the foreign species. We might reasonably suppose that filberts would succeed better in the Southern than in the Northern States, but if the experience of those who have tried them there count for anything, then these nuts are not adapted to the South, owing to the fact that the flowers almost invariably push out during warm days in winter, and these are destroyed later by frosts. In the more elevated regions of the northern border of the Southern, and in similar locations in the Middle States, these nuts will doubtless thrive, or at least the climate will prove congenial. The more equable the climate and free from extremes in temperature, the better; but the most important element in this country is moisture, especially in summer, when the nuts are filling out; and the best way to supply this, where irrigation cannot be practiced, is to keep the ground around the trees continually covered with a mulch of leaves or other coarse vegetable matter. =Planting and Pruning.=--The space to be allowed between the plants, when set out for bearing, will, of course, depend very much upon the size they are expected to attain. Those varieties which assume and remain in the bush form may be planted very close together, or not more than six to eight feet between the plants; but those which become small trees must be given more room. The larger European sorts, which are at present the only ones worth cultivating for their nuts, should be set ten or twelve feet apart, and the rows fifteen to sixteen feet, then if properly pruned they will shade the ground and be in a convenient form for gathering the crop. The trees may be planted in the orchard when quite small, and some kind of vegetable crop grown among them for the first two or three years, but I would prefer keeping the plants in nursery rows until they were four or five feet high, and then transplant to the orchard, and set a short, stout stake by the side of each, to keep the main stem in an upright position until the tree is well established.
