Owing to the fact that little cutting is now being done on this type, 
not many measurements of the rate of growth can be made, but the 
figures given in Tables XII to XV will serve to show how fast the 
four chief species increase in diameter in various localities. 
figures should be used with caution, however, for they belong to trees 
as they happened to be found, and represent widely different condi- 
tions of growth.
