but since the diameter is slightly too high, the total basal area, 

 and consequently the volume, are also too high. 

 The general results, however, are very similar. 



GROUP IA. 1,020 ft. Elevation. 



The height growth of this group has been slightly better than 

 the mean of the best quality class (XL), which at 43 years of age 

 should indicate 62*5 ft. ; consequently it is found also that the 

 mean diameter, although approaching very closely to the tables, 

 is a little too large. The number of trees per acre is also slightly 

 too great. The form factor shows very close correspondence. 

 Consequent on the larger diameter and greater number of trees, 

 the total basal area is approximately 10 per cent, larger. For the 

 same reason the volume is larger. The crop characteristic corre- 

 sponds well with those of the tables. 



GROUP III. 1,460 ft. Elevation. 



Group III. had been treated in an irregular way. This is shown 

 by the relative numbers of trees falling into each diameter class. 

 The result is that, although there were standing 595 trees per acre 

 in all, no less than 130 of these belonged to the minor part of the 

 crop, notwithstanding that the whole had been grown in very open 

 stand. The height-growth is rather too small to fall in the mean 

 of Schiffel's Class IX. light canopy, but approaches more nearly 

 to it than to Class VIII. 



The number of dominant trees (465) per acre is too low, and 

 consequently the diameter is too large, and the crop characteristic 

 too low. 



The sample tree was felled from the densest part, so as to 

 disturb the crop as little as possible, and consequently the form 

 factor is high. The total basal area, and hence the volume, are 

 also considerably too
