fj^ METHOD OF VALUING GROWING TIMBER. 



3tl. The first Table may also assist the valuer of sach 

 timber as is not to be cat down, but to continue growing, 

 by enabling him to estimate its present value more accu- 

 rately than is usually done, especially when it is increasing 

 after a high rate per cent per annum*. 



?4til)lc. The 2d Table shows the rate per cent to be the same as 



in the first Table, though the annual increase is more both 

 in height and circumference. 



SdtaWe. The 3d Table is calculated to show the number of trees 



Dwaiiceof that will stand on an acre of ground, at the distance of 



*^*^ one fifth of their height, (which distance is recommended 



by Mr. Salmon, in a paper in the Society's 24th volume,) 

 and the number of feet the tree will contain, both those to 

 be cut out, and those to be left standing, at the end of 

 every four years, from 16 to 64 years old, supposing they 

 increase 12 inches in height and 1 in circumference annu- 

 ally. This distance may suit fir trees, but will be too near 

 for oaks. 



♦A and 5th The 4th and 5th Tables show the same particulars when 



'^^'*^ the trees grow at greater rates. 



itb table. The Cth Table is calculated to show the same particulars 



when tlie trees are constantly thinned out every four years, 

 so as to leave them at the distance of one fourth of their 

 height. According to this table there will be 48 trees left 

 on an acre when they are 120 years old; and it seems gene- 

 rally agreed, that from 40 to 50 full grown oak trees are a« 

 many as have sufficient room to stand on an acre. 



'.•h table. The /th Table shows the same particulars respecting trees 



which increase 15 inches in height and l| inch in circumfe- 

 rence annually. 



tih tabic. The 8th Table shows the same particulars respecting 



trees which increase 18 inches in height, and 2 inches in 

 circumference annually. 



♦ A fir wood of more tiiaii 30 acres, and about CO years old, was 

 lately Viihicd io be sold with an estate, by several eminent wood valuers, 

 without taking into consideration its rate of increase. It wa^ then in- 

 creasing after the rate of lO per cent per annum, and probably would 

 increase after the rate of 8 per cent on an average for the next twenty 

 j'j-jrs.
