on the tree than the spray composed of winter-strength lime-sulphur to 

 which 40 per cent nicotine was added at the rate of 1 to 500. No man 

 can say without a foreknowledge of the weather what degree of reduc- 

 tion will constitute a control. It is therefore advisable to obtain the 

 greatest degree of reduction possible, and the mixture of winter- 

 strength lime-sulphur to which 40 per cent nicotine has been added at 

 the rate of 1 to 500 appears to give a much greater reduction than the 

 less strengths of nicotine. 



President E. D. Ball: I will now call for the next paper by Mr. 

 A. L. Quaintance. 



Mr. a. L. Quaintance : I wish to explain that I prepared no paper. 

 When I saw that there were already on the program papers dealing with 

 the Japanese beetle and oriental fruit moth, it appeared to me prefer- 

 able to discuss and perhaps elaborate on the papers presented, if oppor- 

 tunity offered, rather than to present another formal paper. Unfor- 

 tunately I missed hearing the papers presented by Professor Cory and 

 Mr. Goodwin, but have no doubt that the subjects were fully covered. 



There are two or three questions relative to quarantine measures, 

 however, and the question of possibility of the eradication which may 

 be of interest to some of the membership. The quarantine question is, 

 of course, in the hands of the state entomologists concerned. As to 

 the eradication of the oriental fruit moth and Japanese beetle, I would 

 say that in my opinion while such eradication is of course within the 

 realms of possibility, provided large funds are available and very drastic 

 measures are adopted, yet I doubt the feasibility and expediency of a 

 program of this character. 



Perhaps all of these questions have been discussed by Mr. Goodwin 

 and Professor Cory and I would not wish to repeat anything since we 

 have still before us a very interesting program. It is suggested there- 

 fore that unless there are particular questions in which members are 

 interested that further time be not taken up with this subject. 



Mr. p. J. Parrott: We people from other parts of the country do 

 not often have the opportunity of seeing Mr. Quaintance, much less to 

 hear him, and I would like very much to have him discuss both of these 

 insects and give us his impression of the situation. 



Mr. a. L. Quaintance: Referring first to the Japanese beetle: 

 We do not know, of course, how much of a pest the Japanese beetle is 

 going to be. While the adults attack a large variety of food plants, 

 some of which are injured to an important extent, it is very probable 

 that such damage can be effectively checked by the use of arsenical 

 poisons spraj^ed or dusted over the plants being injured. The beetles 

 feed upon numerous ornamentals which are now, as a rule, but little 

 sprayed, but which for the most part could readily be sprayed without
