The Autumn is the best time for transplanting trees. Take as much of the root, as possible, especially the little fibres, which should never become dry. If kept long, before they are set out, put wet moss around them, and water them. Dig holes, larger than the extent of the roots; let one person hold the tree in its former position, and another place the roots, carefully, as they were before, cutting off any broken or wounded root. _Be careful not to let the tree be more than an inch deeper than it was before._ Let the soil be soft, and well manured; shake the tree, as the soil is shaken in, that it may mix well among the small fibres. Do not tread the earth down, while filling the hole; but, when it is full, raise a slight mound, of, say, four inches, and then tread it down. Make a little basin, two inches deep, around the stem, to hold water, and fill it. Never cut off leaves nor branches, unless some of the roots are lost. Tie the trees to a stake, and they will be more likely to live. Water them often. _On the Care of House-Plants._ The soil of house-plants should be renewed every year, as previously directed. In Winter, they should be kept as dry as they can be without wilting. Many house-plants are injured by giving them too much water, when they have little light and fresh air. This makes them grow spindling. The more fresh air, warmth, and light, they have, the more water is needed. They ought not to be kept very warm in Winter, nor exposed to great changes of atmosphere. Forty degrees is a proper temperature for plants in Winter, when they have little sun and air. When plants have become spindling, cut off their heads, entirely, and cover the pot in the earth, where it has the morning sun, only. A new and flourishing head will spring out. Few house-plants can bear the sun at noon. When insects infest plants, set them in a closet, or under a barrel, and burn tobacco. The smoke kills any insect enveloped in it. When plants are frozen, cold water, and a gradual restoration of warmth, are the best remedies. Never use very cold water for plants, at any season.
