DISCUSSION 



Mr. Daniel B. Fearing, Rhode Island: I should like to ask the 

 gentleman a few questions : Do I understand the speaker to say that 

 that is an extraordinary size for the cutthroat trout? 



Mr. Land: That is the Riversize. We caught those before there 

 were any fish planted of that size in the Gunnison River, in 1882. 



Mr. Fearing : The reason I ask that question is that I have just 

 returned from a trip through the Rocky Mountain Park in Canada; 

 and in the Spray River there they have a native fish which they call 

 a cutthroat. He looks as much like that fish as a mackerel looks like a 

 trout. He is a bright silver, has the slightest trace of color in him, 

 with black spots. Yet he is called the cutthroat trout in Canada: and is 

 a native fish in all the Rocky Mountain preserves near Banff. An 

 extraordinary size is considered to be two pounds. They catch thous- 

 ands of them from 6 to 8, 10 and 12 ounces, and occasionally at the 

 head waters they catch them up to two pounds ; and then they think 

 they are getting very large trout. The reason I ask is that he is so 

 totally different from the fish you have exhibited. 



Mr. Land: Do they have the markings on them? 



Mr. Fearing : Yes, very slightly. Tt is a silver-backed fish and is 

 by no means the same shape as the fish shown by you. 



Mr. Land: Where do these waters empty? 



Mr. Fearing: The Spray empties into the Bow River. They run 

 down finally into the lakes. The Bow River finally ends in Lake 

 Superior. 



Mr. Land: I take it from Dr. Jordan that those fish have trav- 

 ersed only the Rocky Mountains. On one side they go into the 

 Pacific ; and the other side, as they get lower down 



Mr. Fearing: The streams that 1 speak of are on the Atlantic side 

 of the Great Divide. 



Mr. Land : Yes. 



Mr. Fearing : They flow down, as I say, into Lake Superior. The 

 Spray runs into the Bow and the Bow into Lake Superior. 



Mr. Land: Yes, and I can refer to Judge Beaman to support my 

 statement. 



Mr. Fearing: Is it the same fish? 



Mr. Land: That I don't know — I never investigated those waters, 

 but I will say this, that the sub-species are so different in markings 

 that it is hard to distinguish them by means of spots. We know the 

 Platte by their markings ; and we know those tributary to the Colorado 

 and Snake Rivers in the same way. 



Mr. Fearing: Professor Ward says they are a different fish. 



Professor Ward : I think I quote Dr. Jordan correctly in saying 

 that the term cutthroat trout applies to a group of trout and not to a 

 single type or individual ; and I recall distinctly that there is a great 

 deal of intergradation and confusion between the different species. I 

 had the pleasure last summer of fishing for three weeks in the Rio
