the can, and we did not do a thing to the fish during that 

 time except that we let a siphon hose run on the outside of 

 the can to maintain the proper temperature. 



Grayling, as you know, were found originally in the upper 

 waters of the Missouri, in the Madison, Jefferson, and Gal- 

 latin Rivers, and in their tributaries. I believe those are the 

 only waters in the state where grayling were found. 



This year we took 100,000 grayling to a lake 5 or 6 miles 

 long and 2 miles wide. This lake contained some of the 

 largest native trout I ever saw, some of them weighing 18 

 pounds. The size of the trout showed conclusively that 

 there was a large amount of food in the lake, and I thought 

 it would be a good place in which to plant grayling. In two 

 years some results ought to be apparent from the plant 

 made this year. 



I think you should plant grayling in small lakes, or else 

 in a river that has large pools. I believe that Twin Lakes in 

 this state, or a small lake like the one near the Leadville 

 hatchery is all right. I believe if you put your little fish in 

 there in two years you will have fish that you can take eggs 

 from. 



I do not know that I have anything more to say, unless 

 some one has some questions on the subject to ask. It is 

 easy for me to say I do not know when such is the case, as 

 I have been in the work such a short time. 



DISCUSSION 



Mr. S. E. Land, Colorado : What was Dr. Henshall's experience with 

 the Montana grayling at Bozeman ? Did he hatch them out and handle 

 them successfully, or approve of the distribution of them? 



Mr. Dean : I cannot tell. I do not know of any waters that Dr. 

 Henshall put the grayling in that ever amounted to anything. 



Mr. D. C. Beaman : This grayling question is a matter of consid- 

 able interest on account of the generally conceived opinion that they 

 cannot be artificially reproduced. We have a fish culturist in Colorado, 

 Mr. Hasselkus, of Creede, who is one of our best fish culturists; I 

 hoped he would be here today. He tells me that this summer he got 

 50,0U0 grayling fry from Montana, and planted them in a lake in south- 

 western Colorado. They are now, as I remember, about an inch and a
