PEACTICAL FOKESTRY. 



The measurements made by the Forest Service have shown that 

 the loss from cutting high stumps on a tract of 100,000 acres in the 

 Adirondacks, yielding on an average 15 standards per acre, would be 

 30,000 standards, or at a stumpage value of 50 cents per standard 

 would be $15,000.

The second thing to consider in felling a tree is how to get it down 

 without breaking or splitting the trunk. On rocky, uneven ground 

 this is often a hard thing to do, but unless it can be accomplished the 

 tree would, as a rule, better be left untouched. 



Most important of all for the perpetuation of the forest, each tree 

 must be thrown where it will not unnecessarily injure other trees or 

 crush in its fall the young seedlings on which the future of the forest 

 depends. It happens very commonly in ordinary lumbering that 

 vigorous, sound young trees are split and ruined in great numbers by 

 old trees falling upon them, when it would be perfectly easy and 

 almost or quite as convenient to throw the latter where they would 

 do little or no harm. 



Finally, it must cost as little as possible to fell each tree, for to be 

 successful conservative lumbering must pay.
