entomology he was an enthusiastic administrator. As a writer of books and of many arti- 

 cles during the course of his somewhat short and brilliant career, he has left an im- 

 pression on the entomological world and particularly in Canada. His untimely death at 

 the early age of thirty-five is greatly lamented. During the time he had charge of the 

 Entomological Branch, 1 think the branch has moved forward in leaps and bounds with the 

 organization which he carried on in the various provinces and the work of bringing the 

 importance of entomology to the attention of the public. In the Royal Society of which 

 he was Treasurer, his opinions were always asked for and respected, and although it is 

 hardly my business, I hope that this Society will pass a resolution to send a note of 

 sympathy to his widow. 



You will pardon me, I am sure, referring to this in the address of welcome, but 1 

 feel that a testimony of appreciation of Dr. Hewitt's work should be recognized. 



I do not intend to take up any more of your time. It is rather late in the afternoon 

 and you have an extensive program before you and this is only a one day meeting. 1 am 

 sure that your meetings will be of great benefit to you. We always have a number of 

 students here interested in Entomology and I am sure that they recognize the opportunity 

 of hearing a number of our friends whom your president has brought out for this meeting. 



1 wish your Society every success. 



THE PRESIDENT'S ADDRESS 



THE NATURAL CONTROL OF INSECTS. 

 W. Lochhead, Macdonald College. 



It would almost appear as if Entomologists and Chemists have reached an 

 Aisne line with regard to the control of insects by artificial means. Our spraying 

 mixtures and devices have been developed during the last twenty-five years to 

 such an extent that it is hardly probable that much improvement in these direc- 

 tions will be made. Some changes will be made without doubt in the method of 

 preparation of some of the chemicals used in spraying and some new chemicals, 

 and some improvements will be introduced, but these I surmise, will be of minor 

 importance. 



It seems to me that the next great forward step, and the most difficult one. 

 •of the economic entomologist must be in the direction of the better utilization of 

 the natural agencies in the control of the injurious insects that cause enormous 

 losses in spite of the wonderful development of the artificial methods in recent 

 years. 



To the average layman and others uninitiated into the mysteries of insect 

 life, this method has appealed very strongly, but they fail to realize the great dif- 

 ficulties that stand in the way of a general adoption of such a method. Their 

 imagination has been fired by the successes that attended a few isolated cases.
