 OF PLANTING ARE TO BE ACCOMPLISHED. 



SECT. I. OF THE CLASSIFICATION OF TREES, ACCORDING 

 TO THEJR VISIBLE CHARACTERISTIC DISTINCTIONS AND 

 USEFUL PROPERTIES. 



It seems almost needless to mention, that a botanical know- 

 ledge of every tree and shrub is essentially necessary for the 

 planter; but it is not by minute botanical distinctions that 

 these must be arranged in artificial scenery. The general mag- 

 nitude, form, and colour, are what more immediately strike the 

 eye ; and the effect of trees consists not more in their relation 

 to the surface than in their agreement in these characteristics.

 they are adapted for particular soils, situations, and uses. These 

 are so intimately connected with their distinctions in regard to 

 beauty, that in prosecuting this subject, with a view both to 

 use and picturesque effect, it seems necessary to treat of them 

 together under the following heads :— 1. Magnitude. 2. Form.
