as a number of new buds will then be formed at the end of the 

 branch. Arborvitaes, Japan cypress and junipers may be shorn in 

 spring: and summer. No evergreens should be pruned in autumn. 

 As most evergreens naturally assume a conical form, the encourage- 

 ment of this by pinching back any branches inclined to make an 

 over-vigorous growth is advisable and necessary. Such branches 

 should be cut back to a strong bud, thus leaving a chance for the 

 limb to begin growth again. It is gratifying to note that the once 

 prevalent fashion of pruning evergreens into urns, fowls and other 

 fantastic shapes seems to be dying out. Evergreens are often 

 planted where they are to serve as partial, or open screens, the ob- 

 ject being to afford some seclusion to a dwelling or building in a 

 somewhat public place. In cases of this kind it is desirable to have 

 a thick mass of foliage near the center of the tree while the outer 

 portions are more open. This is accomplished by very close clipping 

 when the trees are young and afterward allowing a natural growth. 

 While this form of a tree is less picturesque than one where the 

 pruning has been more moderate, it is allowable because it serves a 

 definite purpose. With some species this treatment makes more last- 

 ing specimens than where no pruning is done.
