A fruit resembling the lemon, growing in the same climate, but of smaller size. It is used for the same purposes as the lemon, but is not so valuable. Preserved green, it is highly esteemed. It is cultivated as the orange and lemon, needing the same protection in cold climates. To preserve all these from destruction by insects, wash them in a strong decoction of bitter or offensive herbs, or with whale-oil soap-suds; tobacco is very effectual. These remedies are useful on all fruit-trees. LOCATION. This is important to everything we cultivate. But, as everything can not have the best location, we should study it with reference to those things most affected by it, especially fruits. Fruits escape late frosts when growing near rills or small brooks. Orchards near the shores of bodies of water--as on Lake Erie about Cleveland, Ohio--bear luxuriantly when all fruit a few miles back is cut off by late frosts. On the summits of hills, fruits escape late frosts, when they are all cut off in the valleys below. On the Ohio river above Cincinnati, peaches are very liable to destruction by late frosts. We have seen them all frozen through in one night, and turned black the next day, in the month of May, after they had grown to the size of marrowfat-peas. One season, when there were no peaches in any other locality within a hundred miles, we knew an orchard, on a Kentucky hill, so high and steep, that it took miles of winding around the hill, to ascend it with a team. Those trees were perfectly loaded with peaches, that sold on the tree at four dollars per bushel, and in Cincinnati market at seven to eight dollars. In Ohio, Kentucky, and Virginia, there are such hills, that may be turned to more valuable account than any of the rest of their land, that are not now considered good for anything--even for sheep-pastures. The same is true in the hilly parts of all the states. Good fruit of some kind will grow on them all, every year. LOCUST-TREES.
