_For Transplanting Trees_, the autumn is the best time. 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 them 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 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. _The Care of House-Plants_ is a matter of daily attention, and well repays all labor expended upon it. 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 houseplants can bear the sun at noon. When insects infest plants, set them in a closet or under a barrel, and burn tobacco under them. 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. XXXII. THE PROPAGATION OF PLANTS. This is an occupation requiring much attention and constant care. Bulbous roots are propagated by offsets; some growing on the top, others around the sides. Many plants are propagated by cutting off twigs, and setting them in earth, so that two or three eyes are covered. To do this, select a side shoot, ten inches long, two inches of it being of the preceding year's growth, and the rest the growth of the season when it is set. Do this when the sap is running, and put a piece of crockery at the bottom of the shoot, when it is buried. One eye, at least, must be under the soil. Water it and shade it in hot weather.
