Demi. — Grayling 143 



the Fort Collins Game and Fish Association have planted grayling; and 

 they are trying it out, but I cannot say what the result will be. 



Mr. Seymour Bower, Michigan : Where were these fish taken from 

 which you secured the eggs? Were they taken for spawning purposes 

 and directly from this artificial lake or from tributary streams? 



Mr. Dean : This artificial lake was made there because of two large 

 springs — one the lake water covers ; and the other spring is quite large, 

 the flow being probably 5,000 gallons a minute ; and it was in this 

 stream that we had our trap 300 yards, perhaps, from the lake. 



Mr. Willard: I was told by some member of the association that 

 he knew of a party in Colorado who had successfully introduced the 

 grayling and that grayling were being caught in the waters in which 

 he introduced them, of good size. I wonder if that gentleman is 

 present? 



Mr. D. C. Beaman, Denver: I never heard of him. 



Mr. Cranston: I will say for the information of the last speaker 

 that our Williamson whitefish is erroneously called grayling by many 

 people in Oregon ; and I have known it to be distributed as grayling. 

 The outside appearance is similar and in western Oregon it has been 

 called grayling for many years. 



Mr. Land: That is the same case in Colorado and Wyoming. 

 There are certain streams where these whitefish are found and they 

 are classed as grayling by the novice ; but according to Dr. Jordan they 

 are the Williamson whitefish or the Rocky Mountain whitefish. Now, 

 these Montana grayling, I agree with Mr. Dean, cannot be raised and 

 fed ; but they can be raised and liberated, and if out in lakes such as 

 Judge Beaman mentions or Mr. Dean speaks of, they can be success- 

 fully propagated and distributed through other streams that are suit- 

 able. The streams where we find the Rocky Mountain whitefish are 

 streams that have pools, and are not too rapid. We have several of 

 these streams in our state and in Wyoming, and those are suitable 

 for the life of the grayling. The grayling of Montana will grow in 

 streams wherever we find the Rocky Mountain whitefish. The grayling 

 in Montana was first discovered in the head waters of the Madison 

 River, and Thymallus montanus is the scientific name for them. The 

 only grayling known in Michigan is Thymallus tricolor, which inhabit 

 the Manistee and Au Sable Rivers, found especially in pools. The 

 other graylings reported by Dr. Jordan are found in Alaska and are 

 known as Thymallus siguifcr. They have a much larger sized fin 

 than any of the other. They can be successfully raised if planted as 

 soon as hatched, but do not undertake to feed them. 



Mr. Bower : In regard to the planting of the fry, do you place the 

 fry in the streams in which they attempt to spawn, approximately, near 

 the spawning grounds, or do you scatter them throughout the lake, 

 and, if so, in what depth of water ; what are the general methods of 

 planting?
