Pruning is an operation of constant exercise, for keeping plants and trees in good condition. The following rules are from a distinguished horticulturist: Prune off all dead wood, and all the little twigs on the main limbs. Retrench branches, so as to give light and ventilation to the interior of the tree. Cut out the straight and perpendicular shoots, which give little or no fruit; while those which are most nearly horizontal, and somewhat curving, give fruit abundantly and of good quality, and should be sustained. Superfluous and ill-placed buds may be rubbed off at any time; and no buds pushing out after midsummer should be spared. In choosing between shoots to be retained, preserve the lowest placed, and on lateral shoots, those which are nearest the origin. When branches cross each other so as to rub, remove one or the other. Remove all suckers from the roots of trees or shrubs. Prune after the sap is in full circulation, (except in the case of grapes,) as the wounds then heal best. Some think it best to prune before the sap begins to run. Pruning-shears, and a pruning-pole, with a chisel at the end, can be procured of those who deal in agricultural utensils.
Thinning is also an important but very delicate operation. As it is the office of the leaves to absorb nourishment from the atmosphere, they should never be removed, except to mature the wood or fruit. In doing this, remove such leaves as shade the fruit, as soon as it is ready to ripen. To do it earlier impairs the growth. Do it gradually at two different times. Thinning the fruit is important, as tending to increase its size and flavor, and also to promote the longevity of the tree. If the fruit be thickly set, take off one half at the time of setting. Revise in June, and then in July, taking off all that may be spared. One very large apple to every square foot is a rule that may be a sort of guide in other cases. According to this, two hundred large apples would be allowed to a tree whose extent is fifteen feet by twelve. If any person think this thinning excessive, let him try two similar trees, and thin one as directed and leave the other unthinned. It will be found that the thinned tree will produce an equal weight, and fruit of much finer flavor.

THE CULTIVATION OF FRUIT.
By a little attention to this matter, a lady with the help of her children can obtain a rich abundance of all kinds of fruit. The writer has resided in families where little boys of eight, ten, and twelve years old amused themselves, under the direction of their mother, in planting walnuts, chestnuts, and hazelnuts, for future time; as well as in planting and inoculating young fruit-trees of all descriptions. A mother who will take pains to inspire a love for such pursuits in her children, and who will aid and superintend them, will save them from many temptations, and at a trifling expense secure to them and herself a rich reward in the choicest fruits. The information given in this work on this subject may be relied on as sanctioned by the most experienced nursery-men.
The soil for a nursery should be rich, well dug, dressed with well-decayed manure, free from weeds, and protected from cold winds. Fruit-seeds should be planted in the autumn, an inch and a half or two inches deep, in ridges four or five feet apart, pressing the earth firmly over the seeds. While growing, they should be thinned out, leaving the best ones a foot and a half apart. The soil should be kept loose, soft, and free from weeds. They should be inoculated or ingrafted when of the size of a pipe stem; and in a year after this may be transplanted to their permanent stand. Peach-trees sometimes bear in two years from budding, and in four years from planting if well kept.
In a year after transplanting, take pains to train the head aright. Straight upright branches produce gourmands, or twigs bearing only leaves. The side branches which are angular or curved yield the most fruit. For this reason, the limbs should be trained in curves, and perpendicular twigs should be cut off if there be need of pruning. The last of June is the time for this. Grass should never be allowed to grow within four feet of a large tree, and the soil should be kept loose to admit air to the roots. Trees in orchards should be twenty-five feet apart. The soil under the top soil has much to do with the health of the trees. If it be what is called hard-pan, the trees will deteriorate. Trees need to be manured and to have the soil kept open and free from weeds.
Filberts can be raised in any part of this country.
Figs can be raised in the Middle, Western, and Southern States. For this purpose, in the autumn loosen the roots on one side, and bend the tree down to the earth on the other; then cover it with a mound of straw, earth, and boards, and early in the spring raise it up and cover the roots.
Currants grow well in any but a wet soil. They are propagated by cuttings. The old wood should be thinned in the fall and manure be put on. They can be trained into small trees.
