30 PRACTICAL FORESTRY IN THE ADIRONDACKS. 
The following table gives the result of 442 acre measurements taken 
in Nehasane Park during the summer of 1897:

SPRUCE SLOPES. 
These comprise the steep slopes with thin, stony soil. It has else- 
where been pointed out that Beech and Hard Maple, the most persistent 
enemies of Spruce, have difficulty in growing on such soil. The forest 
in these situations is, therefore, chiefly composed of Spruce, with a 
few Yellow Birch in mixture, and with patches of Hemlock and Pine 
on the brows of the ridges. The Spruce is tall and clear, but usually 
of smaller diameter than on hardwood land. The largest specimens 
occur on the small benches and hollows, where the rich wash from the 
hillside has collected. On Spruce slopes the danger from windfall is 
very great, and in consequence the forest is frequently comparatively 
young, the old trees having been blown down. 
The Birch which succeeds in maintaining a foothold on the steep 
Spruce slopes is of excellent quality. The trunks are long, clear, and 
sound. 
The Hemlock and Pine are generally in patches on the brows of steep, 
abrupt slopes, and there is usually under them a smaller growth of 
Spruce. The Hemlock is of inferior quality to that on Spruce flats, on 
account of windshake, to which it is exposed in this situation. 
In the following table, on the next page, which gives the average 
result of the measurements of 274 acres in Nehasane Park, Beech, 
Maple, Ash, Cherry, and Balsam are mentioned as occurring on Spruce
