 poplar, or must be planted. 



The composition of a New England forest is invariably injured

 areas in addition to huckleberry, raspberry, and other shrubs, 

 are inferior, such as poplar, birch, and bird cherry. In northern 

 New England these often form pure forests after a fire. Seed- 

 lings of the original conifers may finally come in, and in the course

 back by fire the character of the forest is not so greatly changed, 

 but the quality is seriously injured. 



The question often arises why it is that softwoods so frequently 

 succeed hardwoods when the latter are cut or burned off and 

 vice versa. It is wholly a matter of seed supply, as may be 

 easily demonstrated by proper cutting of a forest. Softwoods 

 can be made to succeed themselves by leaving enough seed trees 

 at the time of cutting, and this is one of the most interesting
