TABLE No. I. 



Composition on Site I. 

 (Average of ii Acres) 



Number of Trees Per Acre 



The yield of Jack Pine in the diameters 10" and over in the 

 above average is perhaps 25% higher than the average yield for 

 the entire district. 



Type II: Jack Pine in mixture with Black Spruce, Balsam Fir 

 and White Birch on scanty, impoverished, cold and poorly drained 

 soils. All the higher hills, ridges, low lands bordering on 

 muskegs are included in this site. In the Lac Seul country the 

 largest part of the interior regions are occupied by this mixture. 



The Tack Pine here rarely reaches merchantable sizes, and 

 never in such bodies as to make exploitation profitable.
