continuance of this attack ; but I had the great satisfaction this summer of hearing from 

 Mr. Bailey, the head master of the Aldersey Grammar School, Bunbury, Tarporly, Che- 

 shire, that it was not worth while to give me a detailed report again this year, as for all 

 practical purposes the attack was now stamped out in the district. 



This gratifies me exceedingly. Some six or eight years ago, Warbles were described 

 "as p'entiful as blackberries" in the district, and, under the teaching of their admirably 

 intelligent master, the boys, who are mainly sons of farmers and agricultural laborers, 

 set themselves yearly to clear all the cattle they had acccess to of the maggots. I had 

 yearly detailed reports of quantity killed, and now I can point to the district and to the 

 satisfaction of the cattle owners as a proof of what can be done by the simplest hands 

 where head and heart go to the work. 



But now I ought not to add another word, and if there is anything in the fore- 

 going pages which you think worthy of bringing before the distinguished Entomological 

 meeting at Washington, it will be a great gratification to me. I should like much 

 to be present myself, with the double pleasure of seeing many whom I know by their 

 letters are kind friends to myself, and also learning much that would be of enormous 

 benefit to me. (Torrington House, St. Albans, England, July 20, 1891.) 



Mr. South vick moved a vote of thanks to Miss Ormerod for her excellent paper. 

 Adopted. 



Mr. Osborn spoke of the great value of Miss Ormerod's work against the Warble 

 Fly as showing how combination among workers can bring about almost entire immunity 

 from this pest. Miss Ormerod's plan should be adopted in this f^.ountry. 



Mr. Fletcher also spoke highly of Miss Ormerod's work in this investigation. 



Mr. Marlatt, however, stated that the plan of gathering the bots from the backs of 

 cattle can only be practised in the East, where tlie cattle are domestic, and will not pay 

 for the trouble in the West, where the cattle are wild and would have to be roped and 

 thrown. 



Mr. Fletcher thought, however, that the saving of hide value alone would pay for 

 this trouble. 



Mr. Southwick thought that it would be a very easy matter to rope and throw the 

 cattle in the West, and considered that it would pay. 



Mr. Osborn called attention to the fact that the majority of Western cattle are 

 sent East and slaughtered so that the bots have no chance of maturing. He insisted 

 upon the ease of stamping this pest out in restricted localities in this manner, since the 

 Hies do not migrate to any extent. 



Mr. Kellicott stated that he had known the Warble Fly to be very bad in Oswego 

 County, New York. 



Mr. Lintner stated that it is not a general pest in New York State, but occasionally 

 a local one. Mr. Lintner further stated that Miss Ormerod has proven tlie Plum to be 

 less susceptible to the arsenites in England than the Apple — a remarkable fact and not 

 at all in accordance with our experience in this country. This difierence probably 

 depends upon climate and upon difference in varieties. 



Mr. Southwick suggested the reference of this question to the botanists. 

 Mr. Fletcher stated that the different varieties of plums show with him great 

 difference in susceptibility to this treatment. He spoke of the great variation in the 

 texture of the leaf and in other particulars in the varieties of plums. Much work must 

 be done in this direction. He also mentioned the great susceptibility of the peach. 



Mr, Alwood mentioned the fact that the addition of lime water to the arsenical 

 mixture absolutely prevents the burning of the foliage.
