collection of the winter nests, which constitutes the most practical means 

 of control, is much hampered by the old deserted orchards and large growth 

 of seedling apple and thorn in that district. 



In New Brunswick the situation is at present somewhat better, though 

 this Province is menaced constantly by fresh migrations from adjoining 

 States; it is dependent, therefore, to a large extent, upon the activity 

 displayed by the officials of these States in reducing the moths in their 

 territory. 



There can be little doubt but that within a few years the moth will 

 be present in Quebec, and for this reason the Dominion Field Officer to the 

 Entomological Branch spends his winters in the infested area of New 

 Brunswick so that he will be ready to apply the most up-to-date methods 

 of control from the first appearance of the Moth in this Province. Also 

 a scout of certain parts of Quebec likely to be infested first is made each 

 winter. 



The summer of 1913 was marked by a very large flight of moths into 

 New Brunswick from the State of Maine, due to the fact that the prevailing 

 wind at the time of flight was from the west. 



The survey of the Province during the winter of 1913-1914 showed 

 that over 10,000 square miles were infested, and in this area 30,000 winter 

 nests were taken. The 1914 flight from the States was small and at this 

 date less than 250 nests have been taken in New Brunswick, and the work 

 is almost completed. This figure is a tribute to the thoroughness with 

 which the winter work in 1913-1914 was accomplished under the direction 

 of Mr. L. S. McLaine of the Dominion Entomological Branch. 



Female of Brown-tail Moth laying her batch of eggs on leaf. 

 From the Report of the Dominion Entomologist for I'Ml. 



The life history of the Brown Tail Moth is briefly as follows: 

 The white winged moths emerge in July and the female lays a mass 

 of eggs upon the leaf of an apple, or certain other tree. This mass con- 

 tains about 300 eggs, and is covered with hairs removed from a large brown
