side boughs, trees in general grow weakly, 

 and do not attain their maximum height 

 in a minimum time, if ever. On the other 

 hand, single trees, which have plenty of 

 room for their roots, from exposure, or 

 from the quantity of light all round them, 

 generally go more to side branches than 

 to height; but in sheltered situations, with 

 good soils, I have no doubt that, by early 

 and gradual pruning, single trees might be 

 trained to much greater heights than we 

 see at present. Doubtless in ornamental 

 grounds every variety of growth should 

 be encouraged ; and doubtless any variety 

 of growth can be attained by gradually 

 and constantly cutting out all growth ex- 

 cept in the direction desired. To prove 

 this, we have only to observe our wall 

 fruit trees, and the forms of animals, 

 arches, &c. into which trees are cut. In 

 trees, whether for beauty or profit, no 

 attribute is more to be admired or desired 

 than height. In pruning to this end the
