 the leaves in the rod-like variety ovate-acumi-

In order to raise plants for regular plantations, 

 or for handsome standards, it is the best method 

 to raise them principally from young cuttings of 

 one vear's growth, or two at most. These young 

 cuttings should be made about fifteen or eigh- 

 serrate, quite smooth, shining as if varnished, teen inches long, and planted out in nursery-

The layers may be laid down in autumn, 

 choosing the lower young shoots, which are 

 conveniently situated, laying them by slit-lay-

 growth and foliage. It is a native of the islands by the autumn following, in nursery-rows, to

These trees are also capable of being raised 

 from seed, if care be taken to gather a quantity 

 as soon as ripe ; and sow them in autumn, in 

 beds either broad-cast or in drills, half an inch 

 in depth. 



These trees may be employed in assemblage 

 for ornament in out-grounds, which are de-
