REPORT OF THE SOCIETY ' 11 



GENERAL SESSION 



The General Session of the Ninth Annual Meeting was opened at 3 p.m. 

 by the President, Professor Lochhead, in the lecture room of the Biology- 

 Building, Macdonald College. A large number of delegates and many stud- 

 ents of Macdonald College were present at the meeting. 



Dr. Harrison welcomed the delegates to the College, and in a short 

 address expressed his appreciation of the work of the Society. The chief 

 paper of the afternoon was an illustrated address by Dr. F. W. Barrus, of 

 Cornell University, on Potato Diseases. Dr. Barrus dealt chiefly with the 

 physiological diseases of potatoes, and gave a very interesting and valuable 

 account of these imperfectly understood troubles of the potato grower. The 

 paper is printed in full in the Report. 



The evening lecture was given by Dr. W. A. Riley, of Cornell Univer- 

 sity, on "Animal Parasites and Rural Sanitation." Dr. Riley's most in- 

 structive and interesting address dealt with one of the most important 

 aspects of rural sanitation; it was well illustrated and is a valuable con- 

 tribution to the literature of our Society. 



The Summer Meeting 



The Summer Meeting of the Society was held on September 7, at La 

 Trappe in co-operative sessions with the Quebec Pomological Society. The 

 morning was devoted to excursions through the orchards and gardens of the 

 Trappist fathers for the study and collection of insects and fungi, and the 

 afternoon to discussions of the life-histories, habits, and control of the 

 species that had been collected. The great success of the outing was largely 

 due to the hospitality of the Trappist fathers. The members of the Pomo- 

 logical Society present at these sessions were unanimous in declaring that 

 such excursions and discussions were most valuable and helpful. Prof. W. P. 

 Fraser had charge of the collection of specimens of plant diseases, and Mr. 

 E. M. DuPorte that of insect pests.
