PLANTING. The end of October is the 

 best time in the whole year to plant all 

 kinds of trees and bushes which cast 

 their leaves in winter, whether fruit-bear- 

 ing or ornamental ; but all the evergreen 

 American plants, as the Rhodode' ndron, 

 may be planted in October, as well as 

 in July, August, or September the right 

 months for getting in most evergreens. 

 For directions as to planting Fruit-trees, 

 the reader is referred to the article 

 STATIONS ; but much of the following 

 directions relative to planting ornamental 

 trees and shrubs is generally applicable. 

 Wherever they are to be placed, if the 

 soil is at all dry at the bottom, no matter 

 how poor it may be, it should be stirred 

 or trenched three feet deep. In the case 

 of single plants, where a pit or hole only 

 is required, the narrowest diameter ought 

 to be four feet, and if the bottom soil is 

 poor, it should be removed, and some good 

 added instead ; but loose soil of this 

 description will subside in time, and if 

 the plants are tied to stakes, as many 

 need be to keep them firm the first year 

 or two, the sinking of the soil from under 

 the roots may cause them to strain, or 

 otherwise injure them, by cracking and 

 letting in the dry winds to them. Ano- 

 ther evil is, that when trees thus planted 

 sink down gradually, additional soil is 

 placed over the roots to make the sur- 

 face level, and this is equivalent to plant- 

 ing too deep in the first instance, and 

 deep planting is always to be avoided. 

 Therefore the loose or new soil beneath 

 the roots ought to be gently pressed 

 down, and the pit filled up to near the 

 surface of the ground, or to within three 

 or four inches of it, so that, when the 

 tree or bush is planted, the surface of the 

 pit will appear a little mound, several 

 inches above the surrounding surface. 

 Plant fruit-trees shallow and on hard 

 bottoms, to prevent their getting too luxu-
