Along these various lines will the economic entomologist find oppor- 

 tunity for valuable work in the future. At the present rate of prog- 

 ress the next two or three decades nuist witness many important 

 discoveries and improvements, and it may be safely predicted that the 

 science will not fail to respond to the demands made upon it with the 

 increasing material development of our people. 



After the conclusion of the president's address the report of the 

 secretary-treasurer Avas read and referred to an auditing committee 

 consisting of Messrs. Fletcher and Sanderson. On motion, an assess- 

 ment of "25 cents was leA'ied on all members present at the meeting. 



On motion of Mr. Burgess the following committees were ap- 

 pointed : 



Nominations : Messrs. Slingerland, Osborii, and Pbillips. 

 Membersliip : Messrs. Smith, Chambliss, and Titus. 

 Resolutions : Messrs. Felt, Burgess, and Wasbburn.

EXPERIMENTS WITH LIME-SULPHUR WASHES. 



By E. P. Felt. Alhanij, N. Y. 



Experiments Avitli lime-sulphur washes were continued last season 

 largely for the purpose of testing their efficiency and also to gain an 

 idea as to the relative merits of diii'erent methods of preparation and 

 the best quantities to use. Several formuhe, which gave good results 

 last year (1003), were further tested the past season (lOOi), the 

 principal ones being 2.") pounds of lime and 20 pounds of sulphur to 

 50 gallons of water; 25 pounds of lime to 12 pounds of sulphur, and 

 30 pounds of lime to 15 j^ounds of sulphur, respectively, to 50 gallons. 

 All of the washes were prepared as in previous years, the lime being- 

 slaked in a few gallons of hot water in a kettle OA'er a fire, the sulphur 

 added, the whole stirred, and the boiling continued actively from half 

 an hour to an hour and a half. Our observations failed to show that 

 the long boiling gave a more efl'ective wash than the one ]iroduced by 

 the quicker method. Our experiments confirmed previous conclu- 

 sions that a little more lime than sulphur was an advantage, and. after 

 consultation and comparison of data with Prof. P. J. Parrott, of the 

 Agricultural Experiment Station at Geneva, N. Y., we both decided 

 to recommend 20 pounds of lime and 15 pounds of sidphur, with at 

 least thirty minutes active boiling, the use of salt being optional. A 

 wash wherein a large amount of lime is used for the purpose of gen- 

 erating heat, so that boiling is not necessary, can be made as recom-
