By F. E. Buck,, Central Experimental Farm 



Relative Value of Shade Trees with Special Reference to 



Rapidity of Growth 



The "growth tables" published in 

 the March article indicated that as 

 a rule the larger the ultimate size of 

 the tree the greater the growth. This 

 was borne out by actual results taken 

 from growth records over a period of 

 years. 



In the same article the statement 

 was also made that as a rule the 

 greatest growth takes place when the 

 tree is from six to nine years old. 

 This statement is borne out by the 

 growth records which follow. 



Certain trees which appear in these 

 ■ tables are not recommended for street 



or general use in spite of the fact 

 that in the tables they occupy a con- 

 spicuous place in respect to rapidity 

 of growth. In several cities of the 

 United States which issue "permits" 

 to the residents before street trees can

 toba maple, poplars and several others 

 are not allowed to be planted. 



In the first table the poplar shows 

 an average growth of five feet per 

 year for four years. It dropped out

 second growth table was recorded, 

 ten vears later. This fact is signifi-
