26 FOREST COMMISSIONER'S REPORT. 



be seen elsewhere, permitting everyone to judge of its accuracy. 

 Here it will be sufficient merely to summarize results. All dis- 

 counts being made, it is judged that about twenty-four cubic feet is 

 added to the stem wood of the merchantable trees yearly, reckon- 

 ing from the ground up to about six inches diameter. Among the 

 smaller trees there is great variation and not enough were measured 

 to determine their average growth with any degree of accuracy. 

 Perhaps a lump f^mount of ten or tw- Ive cubic feet would not be 

 far out, making the total production of spruce on this acre thirty- 

 six cubic feet. As to the correctness of this last sum I profess no 

 confidence. On the other. howeA-^er, much reliance can be placed. 

 Having performed or revised every step of the process outdoors 

 and in, I feel great confidence that for the annual addition to the 

 merchantable spruce lumber on this acre the sum of twenty-four 

 cubic feet is not far out of the way. The annual growth on the 

 spruce is 1.3 per cent, of the stand and supposing the other species 

 to add to their volumn at the same rate, the total growth upon the 

 acre would amount to fifty -nine and one-half cubic feet. 



For two other pieces of ground similar figures have been worked 

 out. One was located on the south slope of Little Squaw moun- 

 tain to the southwest of Moosehead on very rough, steep, land with 

 little soil. On the acre stood fifty one trees over ten inches through, 

 containing about 1,800 cubic feet of wood which would saw out 

 perhaps 6,000 feet of boards. For the reason that the individual 

 trees that furnish the amount of growth were taken on better 

 ground than the acre I have less confidence in the accuracy of the 

 result. It is given for what it is worth. Reckoned as befoie, the 

 annual growth of the merchantable spruce is nineteen and one-half 

 cubic feet annually. 



The greater part of Februarj' and March last I spent in the White 

 Mountains and in the region of Berlin and Kilkenny in northern 

 New Hampshire. The spruce of the latter named region excelled 

 by far for size and quality any I had ever seen in central and east- 

 ern Maine. On the eastern slope of Mt. Adams, in the Presiden- 

 tial range, most work was done. An acre was staked out there 

 about. 3,000 feet above sea level and 1,000 below timber line, while 

 some thirty trees in the same locality were measured Here there 

 was more wood on the acre, while as might be expected of so high 

 and exposed a situation the percentage of growth falls somewhat 

 short of that ascertained to be characteristic of the better sites 

 earlier dealt with. Carrying out the same reasoning, and making
