 with the good accomplished. 



Combai'mg the insect ivJien attacldng forest trees. — When the 

 caterpillars occur in such great numbers over such wide areas of 

 woodland as they did last spring it is difficult to devise a method 

 of destroying the caterpillars that would be practical for individual 

 farmers to undertake. Banding the trees will be of much value. 

 Also with comparatively little work many of the caterpillars 

 which have assembled on the trunks can be destroyed. What: 

 ever is done a united effort will be necessary to give the best 



results.
