 specimens ranging up to a foot and a half in diameter, while the 

 ground beneath is strewn with the remains of fallen trees. Large 

 red maples are frequent and one large hemlock with a healed 

 fire scar was noted, obviously a relict of the former forest. 



The ultimate association-type of the burn succession is a

 and others of the climax trees beside those already mentioned 

 may appear early in the series, arising either from coppice 

 sprouts or from seed. It seems hardly necessary to describe the
