the lime-sulphur sal-soda wash. The ease with which these mixtures can be 

 prepared will greatly recommend them to the small fruit grower who has not 

 sufficient trees to warrant the installing of a steam boiler plant. 



In the discussion that followed the reading of this paper it was stated 

 tlat.the "McBain Mixture" was too expensive, as it cost |2.50 per barrel, 

 while the lime-sulphur only cost sixty cents. Comparisons had been made 

 ly treating alternate rows of trees with the two compounds. When exam- 

 ined in the middle of July, no difference could be observed and there were 

 badly infested trees in each row ; the same condition was found in August and 

 again in September. As a result it seems that the one mixture is just as ef- 

 fective as the other, and consequently the expensive one is out of the market. 

 At the last inspection some live larvae of scale were still found on trees which 

 had been badly infested at the outset. The lime-sulphur mixture was made 

 with 15 pounds of the former and 17 pounds of the latter, and boiled about 

 an hour by which time it had reached the red amber color stage. 



Evening Session. 



A public meeting of the Society, to which the people of London were in- 

 vited, was held in the Normal School on Wednesday evening, October 26th, 

 by kind permission of Principal Merchant. Though the weather was in- 

 clement, a rainy afternoon being followed bv the first snow of the season, the 

 attendance was very good and the lecture-room was well filled. At eight 

 o'clock the chair was taken by Dr. James Fletcher, Entomologist and Botan- 

 ist of the Dominion Experimental Farms ; after a few introductory remarks 

 hft called upon Professor Lochhead to deliver his address, as President of the 

 Society. 



RECENT PROGEESS IN ENTOMOLOGY. 



(Annual addr^s of the President.) 



Bi Wm. Lochhead, B.A., M.S., Professor of Biology, Ontario Agricul- 

 tural College, Guelph. 



Another eventful year in the history of the Entomological Society of On- 

 tario has just passed, and we are met again to exchange greetings, and to 

 gather information through the exchange of opinions and the reporting of 

 observations. The Annual Meeting of our active members, all interested 

 in a common cause, cannot help but be a tonic in its effect. We return to 

 our separate fields of work stimulated to renewed activity, and refreshed 

 by the mutual exchange of opinions. 



While encouraged by the meeting of so many of our members, we are also 

 saddened by the thought that one of our oldest and most active members has 

 passed away since our last meeting. Mr. J. Alston Moffat, our elder brother, 

 is no longer here to welcome us to our own home. For fourteen years Mr. 

 Moffat was Curator and Librarian of our Society, and for more than thirty 

 vears was an active worker in the field of Entomology. He died on Friday,
