LLZ THE ADIRONDACK SPRUCE 
with great care, and a sufficient number of seed trees 
should be left on the edge of each opening to seed the 
area to Spruce. Such conditions are found on certain 
Spruce slopes and on the tops of ridges and knolls. 
They are nowhere extensive. 
There are other localities, particularly swamps, where 
trees twelve inches in diameter are not plentiful, and 
where many trees under that limit can be removed with 
decided advantage to the forest. 
In general most large Spruce trees, say over fifteen 
inches, are ready to cut. The doubtful trees are those 
close to the limit, whether it be ten, twelve or fourteen 
inches. The trees which should be cut under the size 
limit are: First, those which show signs of decline and 
are more valuable at present than they ever will be 
again; Second, crooked or scrubby trees which can be 
utilized now for pulp, but which are crowding promis- 
ing young growth. Trees which should be left above 
the limit are sound, thrifty, growing trees, which ought 
to remain in order to seed up an area in Spruce, or 
to protect the soil. 
The general rules which should govern conservative 
lumber operations in Spruce timber are as follows: 
1, Only trees marked by the forester must be cut, 
and each tree marked must be cut unless a reason sat- 
isfactory to the forester can be given for leaving it. 
2. Notimber outside the line of a road shall be used 
for corduroy, culverts, or other road purposes, until all 
timber cut for the clearing of the road has been utilized; 
and when more timber is necessary, all available trees
