GENERAL HISTORY. 155 



First Vice-Presidrnt — Patrick Barry, of New York. 



Treasurer — Benjamin Cr. Smitii, of Massachusetts. 



Secretary — (Jha'-les W. Garfield, of Vlicliigan. 



The address of President Wilder was then read. 



"New Fruits" then were discussed. 



In this connection it seems proper to explain that remarks on new fruits 

 are not to be taken as expressing the conclusions of the society, but merely as 

 the opinions of the individuals who may express them. No conclusions of 

 the society respecting varieties of fruits are given except through its cata- 

 logue. 



The afternoon session was consumed in the discussion of new varieties of 

 apples, including crabs. 



The session of Wednesday evening was devoted to a lecture by Charles E. 

 Bessey, Ph. D., of the University of Nebraska, on "Injurious Fungi in 

 their Kelation to the Diseases of Plants." 



The lecture displayc'l extensive research and was highly instructive and 

 valuable in its relations to pomology, especially so in its closing remarks, 

 modes of operation and possible remedies. 



The Thursday morning session, after some preliminary business, was 

 opened with an address on "P. ar Blight" by Professor J. C. Arthur, of New 

 York, confirming the premises and deductions of Professor T. J. Burrill, of 

 Illinois, and apparently demonstrating the agency of bacteria in the produc- 

 tion of the disease, and that they are or may be introduced through the 

 young, growing shoots or through the flowers. 



After the close of the lecture several questions were asked respecting pear 

 blight and yellows of the peach; also respecting modes by which they may be 

 communicated. 



At the close of the lecture the following telegram was received from Presi- 

 dent Wilder: 



To the American Pomological Society, in session at Grand Rapids : 

 Many thanks for the telegram of greeting and congratulation. I accept the trust you 



have again put in my hands. Go ahead, and may God bless the grand old Pomological 



Society.

The Secretary then read a paper from Professor T J. Burrill, of the Illi- 

 nois University, on "Grape liots," of which he stated there are four distinct 

 kinds, although very commonly confounded by most persons. 



L. B. Pierce, of Ohio, followed, introducing the subject of "Methods of 

 Conducting State and Local Horticultural Societies." 



Professor C. V. Riley contributed a paper on "The Mildews of the Grape 

 Vine — An Effectual Remedy for Perouospora," which he subsequently 

 ^mended, and brought its record of facts down to a later date. 



The remedy for peronospora is a European discovery: "Dissolve eight kilo- 

 grammes (-8 pounds) of ordinary sulphate of copper in one hundred litres 

 (about 22 gallons) of any kind of water (well, rain or river); in a separate 

 vt'ssel mix thirty litres (about 6^ gallons) of water and fifteen kilogrammes 

 (about 84 pound;;) of coarse lime, so as to make a milk of lime. Then mix 

 with this the solution of sulphate of copper. These will f^rm a bluish paste. 

 Pour a portion of- the mixture into a bucket or other vessel, thoroughly shak- 

 ing it, and brush the leaves with a small bruom, taking care not to touch the
