METHOD OF VALUING GROWING TIMBER. 



thtir leaves, by unfavourable seasons, and by their roots 

 penetrating into noxious atrata. But these accidents cannot 

 enter into calculations.

Calculations, showing every fourth year from 12 to 64, the Table; 

 progressive annual increase in the growth of trees, and 

 the gradual decrease in the rate per cent 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 eighteen inches in height, and two inches 

 in circumferlence, annually, their increase will be as under-" 

 mentioned, viz.

Explanation of the Construction of Table I and II. 



To render the preceding tables easy to be understood by Construction 

 persons not accustomed to calculations, I will state the pro- °^'^'' "".^ * ^^^ 

 cess of the operations in the first line of Table II. 



The height of the tree at 12 years of age is supposed to
