TOURXAL OF FORESTRY 



The measurements of sample plots on which this statement was based 

 are given below and show the statement to be well founded. The basis 

 of comparison for the site classification is the height as given in the 

 yield tables of Sites I, II, and III, tables 3 to 5, in Bulletin 13, U. S. 

 Dept. of Agriculture, "White Pine Under Forest Management." The 

 results show three of the fifteen major plots as having a height below 

 that given for Site III. They are listed as "Sub III." The departure 

 from normal for Site III may be gauged by comparing the heights and 

 basal areas of these three plots with the values given for Site III. 



Site III. — Age, 35; height, 36 feet; basal area, 167 square 

 vol. = 3,100 cubic feet per acre. 



Plot II. — Age, 35; height, 33.5 feet; basal area, 149 square 

 .•. = SubIII. 



Site III. — Age, 50; height, 54 feet; basal area, 204 square 

 vol. — - 5,200 cubic feet per acre. 



Plot 3. — Age, 50; height, 49 feet; basal area, 106 square feet; . 

 Sub III. 



Plot 6. — Age, 49 ; height, 48.5 feet ; basal area, 134 square feet ; . 

 Sub III.
