success is to encourage the school children to collect the egg 

 masses by paying them a reasonable price per hundred. This 

 may be done by the private individual or by the village or city 

 authorities. In either case the expense would be trifling in com- 

 parison with the good accomplished. 



Combating the insect when attacking forest trees. — When the 

 caterpillars occur in such great numbers over such wide areas of 

 woodland as they did last spring it is difi&cult to devise a method 

 of destroying the caterpillars that would be practical for individual 

 farmers to undertake. Bandiag 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.
