122 THE REPOET OF THE No. 36 



Entomological Laboeatort at Fredericton^ N.B. 



In 1912, a small laboratory was established at Fredericton, N.B., in con- 

 nection with the Brown-tail Moth and other work in New Brunswick. The Uni- 

 versity of New Brunswick provided a site on the University campus. The increase 

 in the infested area, and the large amount of work consequent upon our efEorts 

 to establish the parasites of the Gipsy and Brown-tail Moths imported from the 

 New England States and the carrying on of an extensive study of the natural con- 

 trol of certain native insects such as the Tent Caterpillars, the Spruce Bud-worm 

 and Fall Web-worm, rendered an increase in the laboratory accommodation im- 

 mediately necessary; the University had kindly permitted us to use one of their 

 large laboratories during the summer. 



The building is of solid brick construction and measures twenty-four feet 

 by thirty feet. It consists of basement, ground floor, first floor and attic. The 

 basement contains the water supply for the building, comprising a well, tank, 

 and electrically driven pump, and provides storage room for field equipment and 

 supplies. The ground floor contains at the front offices for the two officers in 

 charge of the work; Mr. J. D. Tothill has charge of the colonization and study 

 of the parasitic insects and Mr. L. S. McLaine has charge of the field work 

 against the Brown-tail Moth and the collection of parasites in the New England 

 States; at the back is a work room. On the first floor a large laboratory occupies 

 the front half of the building and behind a specially lighted room is provided 

 for photographic and other work; a dark room and bath room are also provided 

 on this floor. The high pitched roof furnishes a roomy attic for storage purposes. 

 Steam-heating and electric light have been installed. The building is well 

 situated on the University campus on a site which the University authorities have 

 generously provided. 



The work that is carried on at this laboratory comprises some of the most 

 important investigations that the Branch is prosecuting on the natural control of 

 insect pests. The thoroughness with which the Brown-tail Moth campaign is 

 carried on is evidenced by the fact that by taking the necessary measures from 

 the time of the discovery of the first infestation, it has been possible in New 

 Brunswick to prevent this insect from becoming established in the Province; 

 whereas it is established in Nova Scotia owing to a lapse of some time before 

 the infestation was discovered in 1907 and eradicative measures were begun. 



The small laboratory will be used as a sub-station in another part of the 

 Province. 



Entomological Laboratory at Treesbank, Man. 



Mr. Norman Griddle was appointed in 1913 to carry on investigations on 

 White Grubs (Lachnosterna) and other cereal pests in Manitoba and adjoining 

 territory. As the temporary quarters he occupied did not afford adequate accom- 

 modation for his work a small wooden laboratory measuring twelve feet by sixteen 

 feet has been erected during the past summer on a site kindly provided by Mr. 

 Percy Griddle on his farm where excellent facilities occur for field and experi- 

 mental work. 



Entomological Laboratory at Lethbridge, Alta. 



Investigations on insect and other pests in Southern Alberta were commenced 

 in 1913 by Mr. E. H. Strickland, Field Officer for Alberta, who was provided
