B. C. ENTCJMOLOGICAL PROCEEDINGS, 1912. 69 



sacks and had every fruit in the three orchards, including apples, pears, 

 crab-apples and quince, picked and carted to the sawmill, where I had 

 provided a large tank holding half a carload of apples. Into this tank 

 two jets of steam from the boiler were introduced. I placed 2x4 inch 

 scantlings on the bottom of the tank and put rows of sacks on top of 

 these scantlings. This was to permit the steam to circulate all around 

 the sacks, so as to ensure the cooking of the fruit. Tier after tier was 

 then placed until the tank was full. We then turned on the steam, but 

 unfortunately the pressure was too great, and not only cooked the 

 apples, but blew the pulp and seeds through the sacks, covering the 

 sides of the tank and cover with about an inch of apple pulp. However, 

 needless to say, all the larva? were destroyed. 



In the second grist that we put through we reduced the pressure 

 to about 120. This cooked the apples completely in the course of a 

 few hours, all the fruit being reduced to pulp. 



I regard this as a very valuable discovery, a.s it will enable us, 

 when we shall have completed the new Fumigating Station, to prov' le 

 a chamber whereby we can steam to pulp all condemned fruit rather 

 than have it cremated at a very large expense. This pulp, after having 

 been steamed thoroughly, will constitute food for animals. 



Dealing with these three infected orchards involved a very con- 

 siderable expense. We paid for the apples and cooked them, but I con- 

 sider that no expense is too great if we are to succeed in stamping out 

 incipient infection. This, I believe, has been done most effectively, 

 because I have been able to prove by several experiments that the only 

 way this Codling Moth can be stamped out is to destroy the food on 

 which the larva feed. 



I am informed that as the result of my success at Kamloops, which 

 is well known to most of the entomologists present, Australia has prac- 

 tically adopted a similar method. I am informed by Mr. Hutchison, 

 who has recently returned from Australia and is now resident on the 

 Delta, that this destruction of the fruit is the favorite method of dealing 

 with Codling Moth infection in the Australian States. Mr. Simms, 

 who has been for many years in the Government Service in New Zealand, 

 reports that the Government adopted that method in dealing with the 

 Fruit Fly. 



That we have succeeded in stamping out the infection at Arm- 

 strong, I have the best reasons for believing. The question now is how 

 was this infection introduced ? It is my opinion that cases which con- 

 tained nursery stock which had been shipped from Oregon had been 

 previously stored in fruit-houses badly infected with Codling Moth, and
