330 Method of ascertaining the Value 



To these Tables succeed comparative statements, showing 



the number of feet contained in boles of* different lengths, 



when the trees are 60 years old ; by which it appears, that, 



if cut down at that age, the longest boles are not the most 



profitable to the growers of timber. 

 And I have added the valuation of the plantations before 



alluded to, with remarks on them. * 



Having finished my introductory remarks, I conclude, 



and am, Sir, your very humble servant,

Tables respecting the Growth of Timber. 

 Calculations, showing every fourth year, from 12 to 100, 



the progressive annual increase in the growth of trees, and 



gradual decrease in the rate percent, per annum, that the 



annual increase bears to the whole tree. 



The whole .height of the trees is taken to the top of the 

 leading shoot, and the girt in the middle ; but no account 

 is taken of the lateral branches. 



If trees increase 12 inches in height and 1 in circumference 

 annually, their increase will be as undermentioned, viz.
