SHADE TREES 



light feathery nature, with small leaves which have the habit of 

 closing at night or in dull weather. Too rapid a growth must be 

 deprecated as being productive of brittle wood and short-lived 

 trees. Shade trees may be said to belong to either of two types 

 in regard to habit of growth, viz : (1) centripetal (towards the centre), 

 in which the branches are developed in an upward or horizontal 

 direction ; and (2) centrifugal (from the centre), with the branching 

 system curving downwards or drooping. Trees of the former type

are the most suitable for road-sides or streets, while those of the 

 latter are very effective when planted in parks, pastures or open 

 spaces. The quality of any shade tree may be said to depend 

 largely upon the attention given it when young, as well as on the 

 manner of planting. Careless or improper planting, injury by 

 cattle, etc., when young, or ruthless treatment by disinterested 

 owners of adjoining land, will permanently dishgure shade-trees 

 however good their qualities may be.
