of the outlet, but none of these species have ever been taken in the 

 outlet above the second falls or in either Muskoka or Gull lakes. 



The yellow perch (Perca flavescens) is evidently the most widely 

 distributed and most abundant fish in northern Ontario; next seems 

 to be the pumpkin seed {Eupomotis gtbbosus). There is near shores 

 and in smaller streams a large number of minnows (Cyprinidcs). 

 At Chapleau in the Hudson Bay drainage we found no minnows, 

 though collecting was done where we would expect to find them ; one 

 species of darter {Etheostoma bureale} was found here. 



The game fish laws of Ontario are very strict and well enforced. 

 The object of these laws is to preserve the fishes in the smaller lakes 

 for anglers, and to afford a certain amount of sport and recreation for 

 people in our crowded cities who spend a portion of the summer in 

 this region. At the present rate it will be many years before the 

 small-mouthed black bass {Micropterus dolomieu) and the wall-eyed 

 pike (Stizostedion vitrcuni) become scarce, if ever they do. The worst 

 factors in the destruction of the large fishes of this region are the saw- 

 mills and the cutting and rafting of timber in the streams ; the extent 

 of this destruction can be determined only by considerable study and 

 extended observations. We doubt, though, if these causes will ever 

 have any appreciable effect on the fish supply of this country. Onta- 

 rio is doing well to protect her native game fishes, for the financial 

 gain from the tourist on account of these will certainly be of greater 

 importance to Ontario than the commercial value of these fishes, the 

 taking of which would soon deplete her waters. 



We have included in this paper a small collection of fishes made 

 by the senior author in October, 1900, at Sault Ste. Marie, and the 

 Lizard Islands in Lake Superior. 



Our collections were made as follows: 



Hawkstone: Lake Simcoe and a small stream which flows into he 



lake at this place. 

 Orillia: Couchiching Lake. 



Gravenhurst: Gull Lake, and the upper part of its outlet. 

 Bala: Muskoka Lake, and a small stream near Bala. 

 Katrine: Magnetawan River, and a small lake near by. 

 Trout Creek: Trout Creek, a small rapid stream, tributary of South 



.River, which flows into Lake Nipissing. 

 Nortli Bay: Caught a few wall-eyed pike from wharf. 

 Chapleau: Mattagami River and the two lakes near by. 

 Sault Ste. Marie: The river and a small stream near the city. 

 Lizard Islands; Shore of the islands.
