Yellow Birch and the Adirondack Forest oT 
oldest cuttings available in the Adirondack region. After an 
extensive inquiry it was found that the oldest clear cuttings of 
hardwood land dated back about twenty years on the larger 
logging operations. In three instances, however, pole stands of 
yellow birch were found which had resulted from fire, and in 
one case from the clear cutting of hardwoods for charcoal 
manufacture. 
Second Growth Birch at Lake Ozonia: 
Such a stand was found near Lake Ozonia in the northwestern 
Adirondacks, and complete stem analyses were made on trees ° 
eut in this stand. While the birch in this instance has grown 
without overhead competition, at an age of about sixty years, 
there is a considerable slowing down of volume growth in the 
last ten years. This is due to some extent to the crowding of 
trees on the area, and might possibly have been overcome by 
thinning, but is probably due in a larger measure to a natural 
tendency of the birch to slow down its growth at about this age. 
The rate of volume growth would doubtless have been better if 
the birch had not been forced to contend with the aspen, and had 
the support of a larger percent of beech and maple in the mix- 
ture. A complete statement of existing conditions is given to 
increase the value of the study for comparative purposes.
