In 1914, the Dominion Entomological Branch had nine field laboratories, 

 each in charge of a trained entomologist. These laboratories were located at 

 Bridgetown, N. S.; Fredericton, N. B.; Covey Hill, Que.; Jordon Harbour, 

 Ont.; Strathro,v, Ont.; Treesbank, Man.; Lethbridge, Alta.; Agassiz, B. C; 

 and Vancouver, B. C. In 1924, the Branch maintained 20 laboratories, 

 namely, at Annappohs Roj^al, N. S.; Kentville, N. S.; Wolfville, N. S.; Fre- 

 dericton, N. B.; Hemmingford, Que.; Aylmer, Que.; Ottawa, Ont.; Vineland, 

 Ont.; St. Thomas, Ont.; Port Stanley, Ont.; Strathroy, Ont.; Treesbank, Man.- 

 Indian Head, Sask.; Saskatoon, Sask.; Lethbridge, Alta.; Banff, Alta.; Vernon, 

 B. C; Nicola, B. C; Agassiz, B. C; and Victoria, B. C. All of these with the

Library. 



During the last ten years the library of the Entomological Branch, estab- 

 lished at Ottawa, has assumed important proportions, and it is now undoubtedly 

 one of the best libraries of its kind in Canada. Sets of most of the entomolo- 

 gical journals of the world have been completed and many rare and valuable 

 works of reference for the sj^stematist added. The series of economic bulletins, 

 reports, etc., published bj^ various states and governments have also been 

 largely added to, and an endeavor is being made to receive all current literature 

 as issued.
