Method of ascertaining the Value of Growing Timber Trees, 

 at different and distant Periods of Time. By Mr. Charles 

 Waistell, of High Holborn. 



( Continued from p. 31. J 



A Table showing the Number of Trees to be cut out in Table 3. 

 thinning of iVoods, and the Number left standing at evert/ ^°^ tlnnnmg 

 Period of A Years from 20 up to 64 Years. 



JLn the 24th volume of the Transactions of the Society of 

 Arts, &c., page 75*, Mr. Salmon, in a paper on the Ma- 

 nagement of Fir Woods, says, " the distance of trees from 

 each other should be one fifth of their height." At this dis- 

 tance, which is probably sufficient for fir trees, the follow- 

 ing will be the number on an acre, and the number to be 

 cut out at the ages and heights under-mentioned, and the 

 number of feet they will then contain in the bole, when 

 measured to the top of the leading shoot. Thes-e trees are 

 supposed to increase twelve inches in height, and one in 

 circumference innualiy, and to have been at first planted 

 four feet apart.
