•fourths of an inch in diameter, which I had put 

 there for drainage after removing the churn, but 

 I believe the churn operates better without the 

 opening. 



The plunger consists of a tin cone attached 

 to a three-eighths-inch iron rod, at the other 

 end of which is attached a handle, which may 

 project any distance above the top of the cyl- 

 inder. The cone has a base of such diameter 

 as will nicely fit into the cylinder, and may be 

 from 3 to 3^ inches high. About three-fourths 

 of an inch above the base is a row of five 

 openings of the same size as those in the base 

 of the cylinders; here, too, the number of open- 

 ings may vary, but I have found five ample. 

 In the center of the base of the cone is a 

 large opening three-fourths of an inch in diam- 

 eter. 



The churn may be used with or without a lid. 

 I find it saves time, but wastes a little material 

 at times, to do without the cover. 



The entire cost of making this churn should 

 not be more than 40 or 50 ceots.

Mr. Bethune presented the following resolution relative to the late 

 Dr. 0. V. Eiley, which was unanimously adopted: 



This association at its first meeting since the death of Dr. C. V. Riley, last Sep- 

 tember, who was its originator and first president, desires to place upon record its 

 deep regret at the loss which it has sustained by his untimely removal. He was 

 acknowledged to be the highest authority in this or any other country on economic 

 entomology, and to have held a rarely equaled reputation for scientific work. 

 While entomological science has been deprived of one of its ablest exponents, the 

 members of this association feel also that they have personally to lament the loss of 

 a true and warm-hearted friend. 



The committee appointed to nominate officers for the ensuing year, 

 consisting of Messrs. Smith, Lintner, and Forbush, made the following 

 nominations: 



President, F. M. Webster, Wooster, Ohio. 



First vice-president, Herbert Osborn, Ames, Iowa. 



Second vice-president, Lawrence Bruner, Lincoln, Nebi. 



Secretary, C. L. Marlatt, Washington, D. C. 



A ballot resulted in the unanimous election of the persons nominated.
