Sum of these products 45.3 



From this amount deduct 20 per cent for safety 

 and because consciously and unconsciously bet- 

 ter than average trees were chosen for measure- 

 ment. Tliis leaves total annua' growth of 

 spruce on this acre 36.3 cu. ft. 



Per cent of yearly growth to stand 1.3 per cent. 



Total growth on acre, supposing other species to 



add the same per cent to their volume 59 5 cu. ft. 



Yearly growth on spruce trees over 10 in diara.. . 26.5 cu. ft. 



Of this, there goes into defective trees about 2 5 cu. ft. 



Equivalent of 24 cubic feet in board measure about 144 ft. 



Perhaps a further discount should have been made for the old 

 trees that are past the period of most vigorous growth. 



Site c was located on the lower south slope of Little Squaw moun- 

 tain, just southwest of Moosehead. The trees measured were 

 grown mostly on a liberal soil, in quite open growth, of which 

 about one- half on the average was hard wood. The acre on the 

 other hand was on steep, rocky ground, and more thickly covered 

 with trees. In working from the increment of single trees to that of 

 the acre, I have however, made no allowance for change of site. 



The growth on the acre summarizes as follows : 

 Total number trees (leaving out dwarf maples, etc ) 970 



Number over 10 inches diameter, breast high, 87 



Number under about 6 ft high and 1 inch diam.. .. 450 



Total estimated volume of wood 3925 cu. ft. 



Spruce. Number on acre 448 



Estimated volume of same 2300 cu. ft. 



No. over 10 in. diam. breast high 51 



Estimated volume 1800 cu. ft. 



Merchantable lumber about 6000 ft B. M. 



The other species present are white and yellow birch (some of 

 considerable size) beech and maple, over 200 small fir and some 

 few up to 6 or 8 inches diameter, a few cedar, ash, hornbeam, and 

 a single pine.
