Speaking more particularly of his work in economic, or 

 practical, entomology which occupied the best of his time and 

 labour for at least 25 years, he has truly left behind him a vast 

 store of knowledge in the annual reports which he presented to 

 the people of Canada in the large yearly reports published by the 

 Dominion Experimental Farms, in the special bulletins which he 

 prepared, and in the almost yearly E\'idence which he gave before 

 the Standing Committee on Agriculture and Colonization of the 

 House of Commons, all of which have already been referred to by 

 Dr. Saunders. In all of these publications valuable information 

 on insects injurious or beneficial to agriculturists, horticulturists 

 and others, is given in the most accurate manner, with the remed- 

 ies which have been found most useful for those kinds which are 

 destructive to crops, etc. 



Of the many injurious insects upon which he did original 

 research work, brief mention may be made of the following. 



The Mediterranean Flour Moth, which first appeared in 

 Canada in 1889: its life-history was worked out and the advant- 

 age of freezing the insects by opening the mills to the cold of 

 winter was pointed out, among other remedies. 



The Cigar Case-bearer of the apple was first treated of in his 

 annual report for 1891, and further original observations are to be 

 found recorded in his report for 1894. 



The Hop Vine Borer did much harm in Ontario hop fields in 

 1892. The habits of the insect were studied and published. The 

 same year new facts were learned regarding the life-history of the 

 Red Turnip Beetle, which every year does some damage to cruci- 

 ferous crops in the Prairie Provinces. 



The Pea Moth claimed special attention in 1894. and a 

 lengthy article was published in his annual report for that year.
