_Bearing years._--A cultivator may have a part of his orchard bear one year, and the remainder the next, or he may have them all bear every year. There are two reasons why a tree bears full this year and will not bear the next. One is, it is allowed to have such a superabundance of fruit to mature this year, that it has no strength to mature fruit-buds for the next, and hence a barren year; the other reason is, a want of proper culture and the specific manures for the apple. Manure highly, keep off the insects, cultivate well, and do not allow too much to remain on the trees one season, and you will have a good crop every year. But if one would let his trees take the natural course, but wishes to change the bearing year of half of his orchard, he can accomplish it by removing the blossoms or young fruit from a part of his trees on the bearing year, and those trees having no fruit to mature will put forth an abundance of buds for fruit the following season; thus the fruit-season will be changed without lessening the productiveness. Go through a fruit-region in what is called the non-bearing seasons, and you will find some orchards and some trees very full of fruit. Trees of the same variety in another orchard near by will have very little fruit. This shows that the bearing season is a matter of mere habit, in all except what is determined by late frosts. This fact may be turned to great pecuniary value, by producing an abundance of apples every year. _Plowing and pasturing._--An apple-orchard should be often plowed, but not too deep among the roots. When not actually under the plow, it should be pastured, with fowls, calves, or sheep. Swine are recommended, as they will eat all the apples that fall prematurely, and with them the worms that made them fall. But we have often seen hogs, by their rooting and rubbing, kill the trees. Better to pick up the apples that fall too early, and give them to the swine. Turkeys and hens in an orchard will do much to destroy the various insects. They may be removed for a short time when they begin to peck the ripening fruit. Orchards pastured by sheep are said not to be infested with caterpillars. Sheep pastured and salted under apple-trees greatly enrich the soil, and in those elements peculiarly beneficial. _Enemies._--There are several of these that are quite destructive, when not properly guarded against. Two things are necessary, and, united and thoroughly performed, they afford a remedy or a preventive for most of the depredations of all insects: 1. Keep the trees well cleared of all rough, loose bark, which affords so many hiding-places for insects.
