LAC EMMURAILLE 



seem to be the safest point of departure for 

 the calculation. 



Shift the scene to Lac Emmuraille, 

 where it shall remain. We have here a fish- 

 less lake, before the ten small trout of 1913 

 were released; — the fate of these unknown; 

 — a hundred more convoyed across in 1914. 

 Attentive fishing in the following year, 

 when the weather was not unfavourable, 

 brought nothing to the surface; but the un- 

 discouraged Michel, continuing his visits, 

 was able to report in 1916 that he had seen 

 large trout rising at the natural fly. 



How did we fail in 1915 to discover the 

 presence of these fish? It may be that trans- 

 planted trout are reluctant to rise — having 

 some memory of the fly that hurt and exil- 

 ed them — but this I doubt. In the case 

 in hand it seems much more likely that 

 every need being amply supplied in the 

 depths they could afford to neglect other 

 sustenance. This suggests a view as 

 to the primitive habits of the brook trout, 

 — habits to which they would easily and 

 rapidly revert on occasion. Is it not prob- 

 able that trout are bottom-feeders by na- 

 ture, and only become surface-feeders by 

 force of circumstance? Not a few Lauren- 

 tian lakes contain very large fish to which
