The most interesting of these figures are those which refer to 

 the annual net income per acre and the interest upon capital. 

 The return of jQ\, is. gd. per acre appears at first sight a very 

 high rent to receive for such poor land — too poor mostly for 

 agricultural crops of any sort, — but it must be understood that 

 only a small portion of this (about a quarter) is received as 

 rent for the land pure and simple, the greater part of it 

 being interest on the capital value of the growing stock upon 

 the land. The average total capital per acre is ^47, 6s., 

 of which ;^ii, 1 6s. 6d., or one quarter, may be taken as the 

 land capital, and the remainder, ;^35, 9s. 6d., may be regarded 

 as the capital value of the growing stock on the average.
