SINGLE TREES. 



and shrubs may be varied at pleasure, 

 provided some attention be paid to 

 the general forms, and to the preva- 

 lence of one general form or character 

 of tree or shrub in one place. For 

 example, if conical trees be distri- 

 buted equally over the grounds, along 

 with round-headed trees, they will 

 produce great sameness ; but if coni- 

 cal trees prevail in one place, round- 

 headed trees in another, and flat- 

 spreading trees in a third, so many 

 distinct characters will be produced. 

 The same may be said as to shrubs. 

 The sure mode of proceeding on right 

 principles is to take the different 

 genera, and allow only the species 

 and varieties of one genus to prevail 

 in one place. Single trees should 

 always be planted in prepared soil 

 raised in heaps a foot or more above 

 the general surface ; so that after a 

 year or two, when the earth has 

 settled down, the tree may stand on a 

 little hillock. The trees before plant- 

 ing should be ten feet or twelve feet 

 in height, with trunks three inches or 

 four inches in diameter at the surface 

 of the ground. The shrubs should 

 also be of as large a size as will trans- 

 plant with ease and a fair prospect of 

 success, and this size will vary ac- 

 cording to the kind of shrub. Ever- 

 green trees of the Pine and Fir tribe, 

 and of the Cypress tribe, the beauty 

 of which depends on their spreading 

 branches, should either be planted in 

 a situation where no fence is requisite, 

 or they should be surrounded with 

 iron hurdles or some other light 

 fence placed five feet or six feet from 

 the stem of the tree, and extended to 

 a greater distance as the lateral 

 branches advance in length ; but 

 broad-leafed trees, such as most of the 

 Exogens, may be protected by fences 

 placed close to the stem. There 

 are various modes of doing this : Jig.

 tying thorn branches round the stem [ 



as practised in the Regent's Park, 

 London, and various other places.
