^Measures for the prevention of insect damage, on the condition 
under which the foregoing timbers must be seasoned, can not oe 
promptly discovered by empirical methods. The remedies must be 
based on special entomological investigations aimed at the deter- 
mination of the biology of the borers concerned. The solution of the 
problem lies in the fixation of the correct dates for felling or girdling, 
or of periods during which exploitation is safe. These dates are likely 
to vary from locality to locality.
