32 PRACTICAL FORESTRY IN THE ADIRONDACKS. 
trees, percentage in mixture, and average and maximum diameter of all 
sound trees over 10 inches in diameter on these sample plots are shown.. 
A table prepared from a similar study of the forest in the Whitney 
Preserve would vary somewhat on account of the different proportion. 
of the forest types, but the difference would not be great enough to 
warrant the expense of making such a study.

SPECIAL CONSIDERATION OF THE SPRUCE. 
HABIT. 
In favorable iocalities and in crowded forests the Spruce forms a 
long, clear, full bole, and a rather compact, short, and blunted crown. 
It attains in Nehasane Park a height of 100 feet and a diameter of 34 
inches. These dimensions are, however, rare, and the average for large 
trees is not over 90 feet in height, and, for the diameter, from 24 to 26 
inches. On low, swampy ground Spruce has a long crown, and is com- 
paratively short. The average length of crown for all situations and 
soils is about 40 feet, and the average clear length from 25 to 30 feet. 
The average length of the merchantable log was found to be 46 feet. 
The root system is flat and superficial, and the tree, in consequence, is 
able to thrive on shallow soils. | 
Spruce reaches a great age in the Adirondacks, the largest trees 
being from 200 to 300 years old. The average age of trees of different
