In the preceding 1 example, in applying Brandt's method, the 

 tret-s respectively of the four highest girth-classes heing separately 

 very much less than Z (75), are lumped up together for the 

 purpose of the valuation. 



To complete illustration of Urich's method, let us suppose that 

 we have selected and felled ten sample trees of the respective 

 average girth, and that they furnish the following figures : 



Total basal area of the 10 trees . 



Yield in timber . . 



fire-wood . . 



,, faggot-wood ,, . . 



Then^__. 61 7-228 _ 



a ~ 11-62 53'1, and the contents of the whole crop 



are- 

 Timber = 98-53 x 53 1 = 5,232 solid c. ft. 

 Fire-wood = 856-40 x 53-1 = 45,475 stacked c. ft. 

 Faggot-wood = 84-7 x 53-1 = 4,498 



The completion of the valuation by Hartig's method is effected 

 in the following tabular statement: 



11-62 sq. ft. 

 98-53 solid c. ft. 

 856-40 stacked c. ft. 

 84-70 



Or we may use the formula C = A II F ; whence total contents 

 = 617-223 x '= 38,984, cubic feet.
