Retnatks. Ill Table X of the increase of a bole of 24 feet in height, 



of a tree growing at the aboveiiientioned rate, it will be 

 observed, that the contents at 24 years of age are the same, 

 and at 64 yonis nearly the t-aino as in the above Table, but 

 the contents of the bole at all the intermediate periods ex- 

 ceed the above. And a 40 feet bole exceeds the above con- 

 tents from 44 years to 100, as may be seen in Table 12. 

 For these reasons chi<'fly 1 did not think it necessary to tcke 

 into consideration the decrease in height that takes place in 

 trees at different ages, according to the kind of tree and 

 qualitj- of the soil. 



The increase p'?r cent per annum is the same as the above 

 in all trees at the same age, whether they have grown faster 

 or slower, provided their increase in height and thickness 

 annually has not varied on an average. The progress of 

 trees is son)etimes greatly retarded by insects destroying 



their
