PLANTING. 119 



For, to this office, the faster growing kinds 

 only are appropriated ; and not, as has been 

 erroneously supposed by many, the least va- 

 luable. Their value for this purpose consists 

 in a quick, upright growth in youth, and al- 

 so a multiplicity of branches, which break 

 the force of violent winds; thereby afford- 

 ing shelter to others in infancy, and inducing 

 in them an upright growth, when prone to 

 grow crooked in the stem or squat in the 

 head, by being placed in an exposed situation, 

 or poor soil. 



If the utility of Jiursing in the forest be ad- 

 mitted, it precludes the idea of grouping at 

 the time of planting; and if grouping at first 

 be determined on, it precludes the idea of 

 nursing at all. For, in the present sense, 

 we do not suppose that one kind can be 

 nursed but by the aid of another ; although 

 it must be admitted, that by thick planting, 

 the same kinds may operate, in some mea- 

 sure, to nurse one another. 



This is a strong argument in favour of 



Poplars, Willows, Birch, Laburnum, the Larch, Lime, 

 Mountain-Ash, Horse-Chesnut, &c. may be admitted 

 according to taste.
