Mr. Southwick moved a vote of thanks to Miss Ormerod for her excel- 
lent 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 country. 
Mr. Fletcher also spoke highly of Miss Ormerod’s work in this inves- 
tigation. 
Mr. Marlatt, however, stated that the plan of gathering the bots 
from the backs of cattle can only be practiced in the East, where the 
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 flies 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, 
Dut occasionally a local one. Mr. Lintner further stated that Miss 
Ormerod has proven the Plum to be less susceptible to the arsenites in 
England than the Apple—a remarkable fact and not at allin accordance 
with our experience in this country. This difference probably depends 
upon climate and upon difference in varieties. 
Mr. Southwick suggested the reference of this question to the bot- 
anists. | 
Mr. Fletcher stated that 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. 
Mr. Cook had found the Bot-fly attack much less in cleared farms 
than in wooded farms. In regard to the arsenites, he said that an 
abundance of Aphids and consequent weakening of the vitality of the 
tree might make if more susceptible. 
Mr. Smith suggested that the water referred to by Miss Ormerod 
might contain lime salts so as to make the application more innocuous. 
He stated that the chemical reasons for the prevention of injury to
