164 Fourth Annual Report of the 



Table XX.— MIS CELL Ai^EOUS HARDWOODS Stumpage 



M Bd. Ft. 



The total stumpage is less than we anticipated. The computa- 

 tion shows 8,065,986,000 feet B. M. of timber sizes and pulp 

 wood. There can be no question but the figures are a very con- 

 servative statement of the quantity. It is a matter of experience 

 that ocular estimates when applied to large-sized timber are al- 

 ways low. A comparison of tables showing the contents of trees 

 indicates that in trees having diameters breast high, of from 

 ten to sixteen inches, a difference of one inch in diameter will 

 show a difference varying from 18 per cent, on 10-inch diameter 

 to 14 per cent, on 16-inch trees. The average is approximately 

 16 per cent, of the volume. The eye detects inch classes more 

 readily on smaller than larger sizes, and as the timber on State 

 land is generally of large diameter, the result is an underesti- 

 mate. 



The tables show that 97 per cent, of the total timber is in the 

 Adirondack region; that 93 per cent, of the total is within the 

 Adirondack park ; that 54 per cent, lies in Hamilton county ; that 

 41 per cent, of the total consists of hardwoods, and 35 per cent, of 

 the entire quantity is spruce. 



An analysis of this table seems to indicate that the figures are 

 not as high for hardwoods as they should be. The mixed x^diron- 

 dack forest contains, on the average, about 70 per cent, of hard-
