Fig. 8i. — How to thin a woodlot. 



Conventionalized diagram of thinning in mixed sprout hardwoods. 



The black mark shows the trees to be cut out. Hemlock i and Beech i, though of shade-enduring 

 species, have both been so thoroughly shaded that their tops have been killed and their growth practi- 

 cally stopped. Red Maple i is in the same condition. Red Maple 3, though living, has been partly 

 overtopped by Red Maple 2, which is crowding needlessly. White Birch •?, though a dominant tree, 

 has lost its top in an ice storm, and is therefore not worth preserving. Hemlock 2 below it will be able 

 ultimately to fill its place. White Birches 5 and 6 are, respectively, dead and nearly suppressed by 

 the dominant White Birch 4. Beech 2 is crooked, partly suppressed, and bepinning to crowd Hem- 

 lock 3 which is a promising tree. The remaining thrifty trees, thus thinned, will be able to profit by 

 and fill the added growing space. The trees cut in this case will yield s or 6 cords of firewood per acre.

the battle with each other, they will soon begin really to get acquainted 

 with the trees — which is much better than simply knowing their names, 

 and much more interesting. 



Teachers who write the Forest Service for printed or other information 

 should mention that they are teachers, that their special needs may be 

 recognized in responding to the request. 



"Who plants but for a summertime, has need 



Of steady faith to rule his doubts and fears; 



How full of trust the soul that sows the seed 



Whose harvest ripens not for fifty years! — Elizabeth Akers
