The company will, accordingly, be able to make money by raising 
a second crop, and can afford in the cutting of the present crop to 
exercise due care to leave the forest in a silvically good condition. 
SELECTION OF A DIAMETER LIMIT. 
On Block I cutting and boxing have already progressed so far that 
the cutting limit is fixed at 15 inches diameter breasthigh. Although 
on this block the second crop promises to yield a fair return on the 
investment, vet on the rest of the tract a higher limit will be produc- 
tive of more satisfactory results. 
To raise the diameter limit to 16 inches gives but slight improve- 
ment, but at an 18-inch diameter limit the improvement is marked. 
Only about 600 feet more timber per acre is left standing by raising 
the diameter limit from 16 to 18 inches, while the higher diameter 
limit secures a future yield of over 800 feet more at the end of 20 
vears and of over 1,000 feet more at the end of 30 years. 
At the end of 20 years the future yield from a 16-inch diameter 
limit will not be large enough to be considered merchantable, while 
from an 18-inch diameter limit it will not only be large enough to be 
merchantable, but also to pay 6 per cent compound interest on the 
initial investment, in which is included 1,376 feet of timber left on the 
~ 
ground, worth $2.25 per thousand feet.
