REMEDIES. 



The best remedy for those on the trunk and limbs is a lo per 

 cent solution of kerosene oil. 



Those on the roots are much more difficult to get rid of. If 

 trees have been set but a few years so there is but slight root 

 expanse, the carbon bisulphid treatment would work to good 

 advantage if care is exercised so as not to kill the tree. 



The result of the experiment tried at Bar Harbor will be given 

 in my next report.
