morial Day, or a little before. That is, after the petals have 

 dropped. Then we try to get one in about the last of June. 



Some seasons we may find that we are about to have 

 sooty fungus to spray. Now we vary that somewhat, accord- 

 ing to the weather conditions. It may be between the last 

 of June and the first of July. Then we try to give another 

 one the third or fourth week of July. We find that those 

 usually hold down any fungous disease we may have. 



A MEMBER: We have lost eight colonies of bees, al- 

 though we used a great deal of arsenics, — probably about two 

 tons and a half. The colonies were very strong. 



MR. DAVENPORT: Just one other case might come 

 up. You know the bees gather what we call "honey dew," 

 the honey dew given off by lice and by the pear psylla. Here 

 is another insect we have got to be on the lookout for. The 

 pear psylla in Massachusetts is doing a great deal of damage 

 and no one has seemed to be able to stop it. The trees that 

 are sprayed heavily result in there being more or less lead 

 on the honey dew, and the bees gather that honey dew which 

 also contains some lead. You may get some killing of bees, 

 under those conditions. 



MR. HUTCHTNS: Have three or four sprays a year 

 had any effect on killing bees? 



MR. DAVENPORT: In my own case, in the orchard 

 we keep usually from two to ten hives of bees. We have 

 never lost a hive, and I have not seen any indications of what 

 you might call poisoning of the bees. 



I am afraid that in many cases where we have lost 

 swarms of bees, a great many of the bees have died and we 

 have laid it to poisoning, when, in reality, if we looked fur- 

 ther, we would find something else wrong. Probably most 

 of you know that there are two diseases which are extremely 

 bad in regard to bees, — both American and European foul 

 brood, that in many cases have been the real cause of the kill- 

 ing of a hive of bees, rather than spraying. 



MR. STOCKWELL: In 1915 when there was so much 

 trouble, I had been troubled considerably with the Northern
