also most heartily recommended. Woodland colonies where 

 thinning operations have been carried on should be burned over 

 with a light fire about May 10, or as soon as the eggs have 

 hatched. 



In the late summer there should be a general crushing of 

 pupae and creosoting of female moths before they have oppor- 

 tunity to lay their eggs. Following this, the work of clearing 

 the trees of gypsy moth nests from the ground upward for a 

 distance of 6 or 8 feet, should be prosecuted. As soon as the 

 leaves fall, the usual fall operations of creosoting gypsy moth 

 egg clusters and destroying brown-tail moth nests should begin. 

 In the fall months also the usual work of cutting roadside brush 

 and worthless trees will be carried on. 



One point which cannot be overlooked by the local moth forces 

 without detriment to the Avork is the necessity of mowing the 

 young brush which springs up in the early spring months along 

 roadsides and in woodlands. If this brush can be mowed and 

 burned once or twice during the season, important breeding 

 and hiding places of the gypsy moth will be eliminated. 



In the field operations it has of course been necessary to or- 

 ganize and educate local forces ; and with the experience gained 

 in 1906 there will be greater confidence in the methods out- 

 lined by the central office, and a more general adoption of those 

 found to be effective. 



REPORT OF THE CONSULTING ENTOMOLOGIST. 

 As in 1905, the superintendent has relied for expert advice 

 and counsel upon the consulting entomologist, Prof. C. H. 

 Fernald, whose assistance at all times has been freely given, 

 and has been of the utmost value. No entomologist in the 

 country is more familiar with the gypsy and brown-tail moths 

 than Professor Fernald, while, from his long and successful 

 experience in economic work, his counsel has been of particular 

 value. His report is presented herewith : - 



A. H. KIRKLAND, Esq., Superintendent for Suppressing the Gypsy and 



Brown-tail Moths, Boston, Mass. 



DEAR SIR : Since my report of last year I have made frequent in- 

 spections of the territory infested by the gypsy moth, and learn that 

 this insect has been found in some 15 towns outside of and adjacent to
