For ordinary purposes, but few exotics should be tolerated; and those chiefly in collections, as curiosities, or for arboretums--in which latter the farmer cannot often indulge; and for all the main purposes of shade, and use, and ornament, the trees of no country can equal our own. Varied as our country is, in soils and climates, no particular directions can be given as to the individual varieties of tree which are to be preferred for planting. Each locality has its own most appropriate kinds, and he who is to plant, can best make the selections most fitted to his use. Rapid-growing trees, when of fine symmetry, and free from bad habits in throwing up suckers; not liable to the attacks of insects; of early, dense, and long-continued foliage, are most to be commended; while their opposites in character should be avoided in all well-kept grounds. It requires, indeed, but a little thought and observation to guide every one in the selection which he should make, to produce the best effect of which the tree itself is capable. Giving the importance we have, to trees, and their planting, it may be supposed that we should discuss their position in the grounds to which they should be appropriated. But no specific directions can be given at large. All this branch of the subject must be left to the locality, position, and surface of the ground sought to be improved. A good tree can scarcely stand in a wrong place, when not injurious to a building by its too dense shade, or shutting out its light, or prospect. Still, the proper disposition of trees is a _study_, and should be well considered before they be planted. Bald, unsightly spots should be covered by them, when not devoted to more useful objects of the farm, either in pasturage or cultivation. A partial shading of the soil by trees may add to its value for grazing purposes, like the woodland pastures of Kentucky, where subject to extreme droughts, or a scorching sun. If the planter feels disposed to consult authorities, as to the best disposition of his trees, works on Landscape Gardening may be studied; but these can give only general hints, and the only true course is to strive to make his grounds look as much like nature herself as possible--for nature seldom makes mistakes in her designs. To conclude a course of remark, which the plain farmer, cultivating his land for its yearly profit alone, may consider as foreign to the subject of our work, we would not recommend any one to plant trees who is not willing to spend the necessary time to nurse and tend them afterward, till they are out of harm's way, and well established in a vigorous growth. All this must be taken into the account, for it is better to have even but a few trees, and those what trees should be, than a whole forest of stinted things, writhing and pining through a course of sickly existence.
