16 PRACTICAL FORESTRY IN THE ADIRONDACKS. 
the young timber, in a condition to accumulate interest in the form of 
added wood. ‘he owvers are willing to do without the profits which 
would accrue from the sale of the small trees in order that the produc. 
tive capacity of the forest nay remain unimpaired. The money which 
is thus left invested in the forest the owners expect to recover with 
interest through the increased value of the land. 
THE CONTRACTOR’S OBJECT. 
In the cases under consideration the lumbering is done under con- 
tract, aud the contractor carries on the work himself or sublets it to 
jobbers. Inasmuch as the contractor er jobber obtains a certain sum 
per standard for the logs, it is obvious that he receives the greatest 
profit from the large trees, because the cost per standard of cutting, 
skidding, and hauling is less for the large than the small logs. There 
is no profit at all for the contractor in cutting small one-log trees and 
but little in small two-log trees. He is perfectly willing, therefore, to 
accept a contract to cut only the large trees. 
THE FORESTER’S OBJECT. 
The object of the forester is to obtain for the owner a large revenue 
from the timber, but at the same time to leave the forest in a condition 
to produce a second crop in a comparatively short time, and to reseed 
the openings made in lumbering with young growth of valuable species. 
MEASURES WHICH CAN NOT BE CARRIED OUT IN NEHASANE 
PARK AND THE WHITNEY PRESERVE. 
In order to accomplish the object of the owners on the two tracts 
uuder consideration, and to secure favorable contracts for cutting the 
timber, a number ot measures, usually considered a necessary part of 
forest management, must be given up. These are: 
The maintenance of a sustained annual yield. 
The removal of dead and unsound trees. 
Thinnings and improvement cuttings. 
Permanent roads. 
Planting. 
Fire lines. 
That these measures are not practicable on the two tracts will be 
shown in the discussion following. 
THE MAINTENANCE OF A SUSTAINED ANNUAL YIELD. 
One of the first principles of forestry is to cut timber in such a way 
that the productive capacity of the forest is not impaired. The 
majority of advocates of forestry have interpreted this principle as 
meaning that an equal return should be obtained from the forest every 
year. As a matter of fact, the object of forestry is attained if the
