152 TREE-PLANTING. 



the American continent attains a height of sixty feet, 

 being the tallest hardy tree of the genus. 



It flourishes best in a deep rich soil, and will 

 endure plenty of moisture, assuming a conical form, 

 and expanding into a broad spreading tree, affording 

 a great amount of shelter. Being very hardy, it is 

 highly appreciated in the shrubbery as a nurse for 

 more tender plants. It is propagated from seed, and 

 during the first four or five years of its growth, its 

 progress will be as fast as that of the Scotch pine ; 

 while no plant is more apt to produce greater seedling 

 varieties, differing in the size and shape of their 

 foliage, all of which are invariably handsome. The 

 young plants should be transplanted from the seed- 

 bed when one year, or at most two years old, into 

 nursery lines, and transplanted again every second 

 year, until finally planted out. 



The Common Savin (J. sabina). This is one of 

 the least ornamental of the species, and when dis- 

 turbed, or trod upon, emits a disagreeable odour. It 

 is a low spreading, evergreen shrub, which is indi- 

 genous to Spain, France, and Italy, and consists of 

 several varieties which readily take root by fixing the 

 prostrate branches in the earth. It is said to produce 

 abortion when eaten by pregnant domestic animals, 

 its foliage being used in medicine as a diuretic. 



The Bermudas Cedar (J. Bermudiand). The 

 wood of this tree is that employed in the manufacture 

 of blacklead pencils, being esteemed on account of its 

 fragrance. It is however too tender to be reared 

 successfully in Britain generally, and in the most 

 favoured situations seldom exceeds the stature of a 

 shrub, and is not therefore much cultivated, except
