28 B. C. ENTOMOLOGICAL PROCEEDINGS, 1912. 



possible. As we obtain most of our natural products and with them 

 our new insect pests from non-British countries, it was necessary, if the 

 scheme were to be of use to us, and in our opinion of real use to the 

 other Colonies, that its survey should not be confined to the British 

 Empire, but should be world-wide. Such a more extended scheme was 

 considered to be desirable by us. I conferred with the Colonial Office 

 authorities in London in January and in August, after the International 

 Entomological Congress, the Rt. Hon. the Secretary of State for the 

 Colonies called another conference of the Government entomologists of 

 the Dominions and Colonies and of the Entomological Research Com- 

 mittee of the Colonial Office to work out a scheme for inspection co- 

 operation. 



At this conference the more extended scheme whicii we proposed was 

 unanimously adopted and an Imperial Entomological Bureau will be 

 formed and will be maintained by financial contributions from the 

 self-governing Dominions and Colonies and also from the Colonial Office. 

 It will supply information on the subject of insect pests and will also 

 identify insects sent in by those entomologists who have not access to large 

 collections or who are unable to get their material identified. One of 

 its most useful functions will be the publication of a journal containing 

 abstracts of current literature relating to insect pests and their control. 



The co-operation which will result from the formation of this 

 Bureau will be of undoubted benefit to the Colonies concerned and will 

 materially assist all parts of the British Empire in their efforts to 

 control insect pests." 



AFTERNOON SESSION. 

 "CARBON BISULPHIDE FUMIGATION." 



During the last ten to twenty years many methods aiming at the 

 destruction of insect pests infecting trees, shrubs, plants and grain, etc., 

 have been put into practice. 



The (problem has always been : What is the most deadly to the 

 insects, the least harmful to the stock they infect, and also within the 

 bounds of economic practice? 



The methods in use may be quoted as, Spraying, Dipping and 

 Fumigating. All three of these have their special merits, according to 

 the conditions under which they are applied. 



Fumigation has been very extensively adopted by the Government 

 Departments in many parts of the world, for the purpose of preventing 

 the spread of insect pests from one country to another.
