THE DOUGLAS FIR PLANTATION AT TAYMOUNT.

The tree was found to measure 3 inches in diameter at 48 feet 

 from the ground, and there it was cut through. It was then 

 divided into eight sections of 6 feet each, each of which was 

 measured, with the following result: — 



The top and branches measured 50 cubic feet, say — 

 50 X -15 = 7*5 cubic feet of solid wood. 



These figures are calculated by Dr Schlich to give a total 

 volume of wood, exclusive of top and branches, of 3738 cubic feet 

 per acre. The trees being four years old when planted, had 

 reached an age of nearly thirty -two years on July 20th, 1888, so 

 that the increment, apart from thinnings and branches, was 117 

 cubic feet per acre per annum. 



By the courtesy of the Earl of Mansfield, I have been able to 

 bring the statistics of this interesting wood up to date, by measure- 

 ments taken by Mr Pitc.iithley on June 22nd, 1903. Two typical 

 areas, each of y\j acre, were selected, and the trees counted 

 and measured. The results are given in the accompanying 

 Table :—
