104 GYPSY AND BROWN-TAIL MOTHS. [Jan. 



be desired on private estates above the owners' financial 

 liability. Such being the case, the principal efforts will be 

 directed to stamping out the moths in the most generally 

 infested residential sections. So far as funds permit, the 

 woodlands having the worst gypsy moth infestation will be 

 thinned, the egg clusters on the remaining trees destroyed, 

 and the colonies put in condition for economical banding or 

 spraying. 



As soon as the gypsy moth eggs hatch next spring, these 

 colonies should be burned over with a light fire to destroy 

 the young caterpillars on the ground growth. Burlapping 

 for caterpillars will be desirable on street trees generally 

 throughout the central infested district. Arrangements are 

 being perfected for a vigorous campaign of spraying. In 

 many of the central towns all the street trees should be 

 sprayed ; in the outlying towns the trees standing in or near 

 infested places will require the same treatment ; and, so far 

 as time and funds permit, spraying also will be prosecuted 

 vigorously in the woodland colonies. In the central towns 

 the burlaps will require frequent inspection, and also in all 

 infested sections in the outer towns. 



All available resources must be brought to bear in the 

 effort to prevent the farther spread of the gypsy moth, 

 whether locally or to a distance. Every mile added to the 

 outlying border tremendously increases the total infested 

 area and the expense of the work, and the same considera- 

 tions apply to the establishment of new colonies within the 

 known infested district. 



As soon as the gypsy moth egg clusters have been laid, in 

 the late summer, creosoting operations will begin, particu- 

 larly on those within reach from the ground, in order to 

 prevent them from becoming broken and the e<-s from

being scattered. Following this, the regular campaign of 

 fall cleaning of gypsy egg clusters and of brown-tail web 

 destruction will be in order. 



From time to time the superintendent has freely called 

 upon Prof. C. H. Fernald, Amherst, Mass., for consultation 

 and advice, which has been as freely given. From his 

 position as entomologist for many years to the gypsy moth
