investigations of this kind, namely, the study of the food of our fresh-water fishes 

 in relation to their conservation. This matter has a very important bearing on 

 the question of our national food supply. I think if a resolution of this nature 

 were passed and forwarded to the Commission of Conservation it would do much 

 good and would be preferable to our retaining our opinions on this vital matter 

 to ourselves. I beg to propose, therefore, the following resolution: 



" That in view of the decrease in the supply of the fresh-water fishes of 

 Canada the attention of the Commission of Conservation be called to the im- 

 portant fact, which is being overlooked in the endeavours to replenish depleted 

 waters by restocking and to stock new waters, that as the chief food of many of 

 our important fresh-water fishes consists of larval and adult insects a study should 

 be made of the available or possible food supplies in the way of insect life before 

 attempts are made at replenishing or stocking waters; otherwise, by stocking 

 waters in which the food supply is not suitable or cannot be made suitable, large 

 sums of money and considerable time and energy will be uselessly expended owing 

 to fish being planted where the food is either insufficient or of the wrong char- 

 acter, as the conservation of our fresh-water fishes cannot be successfully carried 

 out until more knowledge is available as to their feeding habits and requirements, 

 and concerning the insect and other fauna and available food supplies of the 

 waters in which they are living or which it is desirable to stock with fish, and that 

 a copy of this resolution be forwarded to the Secretary of the Commission of 

 Conservation. 



Mr. Swaine : I am glad to second such a motion. 



The resolution was put to the meeting and carried unanimously. 



mSECT PESTS OF SOUTHERN MANITOBA DUEING 1912.

In this paper an attempt is made to give a brief account of the more prominent 

 insects found attacking both vegetation and live stock in the vicinity of Aweme, 

 Manitoba, during the season of 1912. Broadly speaking, there are a number of 

 insects, of which we know comparatively little, doing considerable injury to crops 

 that require careful study, not only in Manitoba, but in Saskatchewan and Alberta 

 also. In all these provinces the enormous acreage under cereals has placed almost 

 unlimited food at the disposal of insects that formerly existed only in a few 

 native grasses, and which were controlled very largely by the condition and 

 prevalence of the plants they inhabited. Under the new conditions there is no 

 telling how far afield some of these species may spread, or how much damage 

 they may accomplish. 



During 1912 several insects were present in damaging numbers, of which the 

 following were most noticeable. 



1. Insects Injurious to Grain and Grasses. 



Hessdan Fly. This species was present in small numbers in late June, when 

 a few larvfe were discovered near the base of wheat plants. On July 13 a few 

 pnpge were secured, of which, unfortunately, all but one died. This single in-
