because cutting to this limit will leave a certain number of trees for seed. 

 Cutting to 14 inches will yield an amount of Pine equal to 8f of the rut of 

 Spruce to 12 inches. 



These diameter limits for Spruce. Balsam, and Pine refer, as has been 

 stated, to the diameter breasthigh. or 4I feet from the ground. These 

 limits must not be confounded with what the diameter would be at the 

 cutting point on the stump, as the following table shows. 



The figures used in constructing this table were determined by 2 624 

 measurements taken on this tract and upon Township 39, where lumbering 

 has been carried on under the supervision of the Division of Forestry dur- 

 ing the past summer (1900). The work was done under watchful inspec- 

 tion and according to the rules of the Division for lumbering, and all stumps 

 were cut at the lowest practicable point. The measurements were very 

 carefully taken, and the results may be relied upon for Spruce.
