2. Good sound straight logs ordinarily should not be used for fuel, 

 since they are more valuable for lumber. There is a great difference 

 between the prices paid for logs of different grades, even of ( 



kind of wood. Branches, crooked and decayed logs, trunks broken 

 in felling or otherwise defective, should he used for firewood. 



3. Trees likely to he attacked by insects or fungi should be removed 

 to safeguard those which remain. In eastern New England, for 

 example, the gipsy moth is a serious enemy of the aspen, basswood, 

 beech, gray and paper birch, boxelder, serviceberry. dwarf and e 

 horn sumac, tamarack, glaucous willow, witch hazel, and practically 

 all the native oaks. 1 Several of these species are of little value and 

 can well be removed, thus reducing the food available for the in- 

 Where the chestnut blight is serious, the chestnut should be largely 

 cut . 



4. No portion of the woodland should be cut clean unless the owi er 

 has carefully considered the matter and decided that that particular 

 part is best adapted for farm purposes or that he will replant it with 

 forest trees. Old trees, where they predominate, should be gradually 

 removed, since they are not increasing in value. The next generation 

 of trees will be largely determined by those which are left for seed. 

 The successful dairyman studies his records as kept by the 

 testing association, sells his less profitable cows, and breeds i 

 which are nroducing the greatest amount of butter fat. In the ss me 

 way the successful woodland owner will study the growth and uses of 

 the different kinds of trees. He will then cut out those of little 

 value and slow growth and keep for seed purposes those which will 

 produce valuable lumber in a relatively short time. Table 3 clari- 

 fies in a general way the trees which should be favored and those 

 which should be removed for fuel. Inferior individuals of tie better 

 species, e. g., those which are diseased or which are likely to he 

 blown over, should, of course, be cut.
