For best five plates of winter apples for dessert, to S. W. Dorr, Manchester, 

 for Newtown Pippin, liubbardston, Jonathan, Belmont and Wagener. 



A large number of plates not entered for i)remium, were also exhibited, 

 among which were fine collections by Charles Arnold and William Sauiiders, 

 of Ontario, Prentiss grape, by T. S. Hubbard, of Fredonia, N. Y., Niagara 

 grape, by Lhe Niagara Grape Company, of Lockport, N. Y. 



The committee on plants and flowers also made their report, the gist of 

 which is given in the resolution previously adopted by the society. 



The remainder of the session was devoted to memorial exercises in honor 

 of Jonathan Palmer Thom[)son, a president, and subsequently a secretary of 

 the society, who died at Detroit, July 8th, 1880. 



S. L. Fuller, of Grand Eapids, gave a history of Mr. Thompson, and spoke 

 feelingly and appropriately of his valuable services and estimable qualities. 



The secretary read a letter from A. T. Linderman, the first secretary of the 

 society, expressing his high appreciation of Mr. Thompson, and regretting 

 his inability to be present. On motion of H. Dale Adams, of Galesburgh, 

 the following preamble and resolutions were adopted by a rising vote: 



Whereas, By the death of Jonathan Palmer Thompson, this society has lost one of 

 its earliest and best friends, whose efforts were untiring for its success and whose wise 

 counsels have largely contributed to its present prosperity ; therefore 



Resolved, That, in the death of Mr. Thompson, this society has lost a wise counsellor, 

 a sincere friend and a most earnest worker, and the State a most valuable citizen. 



Resolved, That these resolutions be spread upon the rocords of the society, and a copy 

 transmitted by the secretary to the family of Mr. Thompson. 



On motion of Mr. A. C. Glidden, of Paw Paw: 



Resolved, That the secretary be instructed to secure an engraving of Mr. Thompson , 

 to be placed in the transactions of the society as soon as practicable. 



Eesolutions thanking those who had contributed to the success of the 

 meeting and its accessories, and to the pleasure of those in attendance were 

 adopted, whereupon the society adjourned. 



During the year 1880 Secretary Garfield, acting under instructions from 

 the executive board, made an effort to gather material for a history of Michi- 

 gan horticulture by means of circulars of inquiry and also through private 

 correspondence. The results were more meagre than had been anticipated 

 and were embodied in the transactions of that year. 



The late S. B. Peck, of Muskegon, contributed a paper to the New York 

 Sun, copied in the secretary's portfolio of 1880, advancing the opinion that 

 the codling moth larva is migratory, not confining itself to a single apple, 

 but passing from one to another, often attacking and ruining several apples 

 before pupating. The observations and experiments upon which this conclu- 

 sion is based were commenced as early as 1875 and were strongly confirmed by 

 the observations of others. The correctness of this conclusion has been 

 questioned upon high authority but is sustained and confirmed by the evi- 

 dence of many persons of wide experience and careful observation. 



The experiments of T. J. Burrill, professor of botany and horticulture at 

 the Illinois Industrial University, developing the idea that bacteria are in 

 fact the cause of pear blight and of yellows in the peach were published 

 during this year and have more recently been confirmed and amplified by the 

 experiments of Professor Arthur, of the New York experiment station.
