An Article for All Planters and Shade Tree Owners 



Relative Value of Shade Trees, with 



Special Reference to Rapidity 



of Growth 



^y F. E. Buck, Central Experimenial Farm, Ottawa 



The sole object in planting shadj 

 trees is not merely to obtain shade : 

 indeed one main object is to complete 

 the architecture of the street or hous: 

 surroundings, as the case may be. 

 Quick realization of the objects in 

 planting a shade tree is of course de- 

 sirable, but rapidity of growth is gen- 

 erally looked upon as an undesirable 

 characteristic of a shade tree. The 

 reason is obvious perhaps. Rapid 

 growth is generally correlated to 

 weakness of wood and tendencies to 

 decay, and therefore a short-lived tree 

 is the result. A tree is a living beau- 

 tiful thing, and its values reside in 

 its more permanent qualities of 

 beauty of form, cleanliness, longe- 

 vity, etc., rather than in the tempor- 

 ary quality of quick growth. 



Nevertheless, with these reserva- 

 tions recorded, it may be said that 

 there is an advantage in having 



shade, especially where combined in Cressman's Woods, of which Waterloo County, 



with other good qualities, just as soon Ontario, is justly proud.
