oak In size and often in number. This is especially true in the 

 older age classes, so that we recognize this type as a chestnut 

 rather than as an oak type. 



White Pine. — This type is more likely to be a pure stand 

 than any of the others, although we put into this type any 

 stand which is more than 60 per cent. pine. The hardwoods 

 in mixture are usually birch, maple and oak. The pine, being 

 the more vigorous grower, rapidly overtops the hardwoods, and 

 before the oldest age class is reached has killed most of them, 

 forming a pure stand. 



Pine and Hardwoods. — Inasmuch as stands with more than 

 60 per cent, of pine have been put into the pure pine type it 

 follows that the stands in this mixed type have, as a rule, rather 

 more hardwood growth than coniferous. On the average the 

 proportion of hardwood growth is 2 to 1. The hardwoods 

 usually found in mixture are gray birch, maple, oak and 

 chestnut. The first three are more liable to be found in 

 Classes 4 and 3 and the last three in Classes 2 and 1. In the 

 northern part of the county there is considerable sugar maple, 

 beech and white birch which will be found in this mixed type, 

 especially in the older classes superseding oak and chestnut. 



Gray Birch and Maple. — This type is a sort of miscellaneous 

 affair into which we put the tag ends. We at first called it 

 mixed hardwoods, but, finding that in 9 cases out of 10 the 

 type consisted of a mixture of gray birch, maple and an 

 occasional oak, decided to call it by that title. Gray birch 

 exceeds the maple in the small classes and the maple exceeds 

 the birch in the older classes. In the northern part of the 

 county Classes 1 and 2 are likely to be largely sugar maple and 

 white birch. This is the type which comes up on old run-out 

 pastures. In swamps maple rather rules ove^ birch, but not to 

 so great an extent as might be supposed. 



Conifers Other than White Pine. — This type usually includes 

 both hemlock and pitch pine, not that there is any association 

 between these species, but the aggregate amount of their area 

 was too small to be separately classified. In a town where this 

 type was almost entirely one of these species it is so named. 

 In the north part of the county there is a good deal of spruce 

 and tamarack in the swamps, which are included in this type.
