As will be seen from these records, the poles and saplings of the 

 leading species are abundant, a hopeful condition, assuring the repro- 

 duction of the forest of the same nature. Where the forest has been 

 thinned by lumbering, the vigour of the reproduction is all the more 

 striking. In such situations one often finds dense thickets of young 

 maple, beech, and yellow birch. Maple, however, is by far the most 

 abundant among the seedlings and small saplings. One finds it every- 

 where. Sometimes a dense carpet of maple seedlings covers several 

 acres to the exclusion of nearly all other plants. 



The Mixed Type 



The mixed forest type as exhibited on the accompanying map 

 represents in reality a combination of two distinct types, namely the 

 mixed hardwood-conifer type of the well drained areas, and a mixed 

 swamp type. This swamp type representing nearly one-half of the 

 combination, is the ordinary black ash-cedar-balsam swamp. In the 

 former type, which is found on the flats and at the bases of slopes along 

 streams and lakes, and on some of the low ridges rising above the pxure 

 hardwood forest, the principal conifer associated with the hardwood 

 is hemlock ; balsam usually holds the second place. The combination, 

 as given on the map, opcupies 59,600 acres, or 5.1 per cent of the entire 

 area and 6.1 per cent of the forested area. A little more than one- 

 fifth of the mixed type is moderately culled ; nearly three-foiuths is 

 severely cuUed ; and the remaining one-twentieth is young growth and 

 second growth.
