It has already been mentioned that the final objectives for 
oak and ash at seventy years are as follows:

From stumps whose diameters at breast high were within 
an inch of the expected or ideal final diameter, the curves of 
diameter growth for both oak and ash were obtained. From 
these curves the diameters and heights, falling between the 
limits given in the two preceding tables, were taken. From 
felled sample trees the curves of height growth were obtained 
similarly. 
The tabulated results were as follows:

In the case of ash, if on the graph we join the point 9.1 feet, 
crown radius at seventy years, with the origin, it would give a 
crown radius of 1.3 at ten years. This agrees closely enough 
with the radius in Table XVI, which was 1.2 feet. Taking the 
value 1.3 feet for ten years, this would give a radius of 3.9 at 
thirty years. Two stands of this age were examined and the 
results are given in Table XIX.
