310 BRECK'S BOOK OF FLOWERS. 



drons, and other equally difficult trees and shrubs to manage 

 in a northern climate, will, if anywhere, succeed. 



Mr. Downing says : " Well-grown belts of evergreens, pines 

 and furs, which, 



in conic forms arise, 



And with a pointed spear divide the skies,' 



have, in their congregated strength, a power of shelter and pro- 

 tection that no inexperienced person can possibly understand, 

 without actual experience and the evidence of his own senses. 

 Many a place, almost uninhabitable from the rude blasts of 

 wind that sweep over it, has been rendered comparatively calm 

 and sheltered. Many a garden, 90 exposed that the cultivation 

 of tender trees and plants was almost impossible, has been ren- 

 dered mild and genial in its climate, by the growth of a close 

 shelter, composed of masses and groups of Evergreen Trees." 



Most of the northern Evergreen Trees are enumerated and 

 described by Mr. Emerson, in his excellent work on " The 

 Trees and Shrubs of Massachusetts," to which we would refer 

 our readers for many interesting details and particulars, and 

 from which we have made many extracts. 



He says : " The pines, firs, junipers, cypresses, larches, 

 hemlock, and yews, with some foreign trees, form a very distinct 

 and natural group. The name Evergreen, by which they are 

 commonly known, is liable to the exception, that one of the 

 genera found in this climate, the Larch, loses its leaves in win- 

 ter. The Evergreens are divided into three sections : 



" 1st. Those whose fruit is a true cone, with numerous im- 

 bricate scales, like the fir and pine. 



" 2d. Those with a globular, compound fruit, like the cypress 

 and arbor vitae. 



"3d. Those with a globular, compound fruit, like the yew."
