AMERICAN FISHERIES SOCIETY. 83 



this year to the station of which I have charge. They were 

 billed to me as fifty thousand e-igs. They came the forepart 

 of June, probably the 10th. a very warm time, and they were 

 micely packed with an ice tray. 'The loss on these ep^gs was 

 quite considerable, I should presume ten per cent. Some of 

 them had hatched and died, but after they were thoroughly 

 sorted out they measured up about sixty-seven thousand. 

 They were said to be fifty thousand when they were sent. That 

 is something remarkable, because fish culturists sometimes 

 ship less than they count out on arrival at destination. I feel 

 well assured that this is going to be a valuable work of the 

 United States Fish Commission. I immediately wTote Wash- 

 ington after carrying them along until the time of distribution, 

 and praised the work highly, and recommended that next year 

 at least five hundi'ed thousand be forwarded to the Northville 

 station. Mr. Ravenel informs me that if the money is avail- 

 able they will send us all we want. The Montana grayling 

 fry are very much different from the fry hatched from the eggs 

 of Michigan grayling. They do not act the same in the troughs 

 at all. After hatching, they settle on the bottom of the trough 

 the same as trout fry. The fry hatched from the Michigan 

 grayling about fifteen years ago at our station are free swim- 

 mers, the same as a white fish; but in the case of the Montana 

 grayling they lie on the bottom of the trough from twenty- 

 four to forty-eight hours before they begin to swim. Then they 

 begin to swim, and of course the sac is absorbed in a very few 

 days, about six or eight days; between the sixth and eighth 

 day the}' begin to take food. We have them there now. 

 and if you could take a look at them you would see them under 

 different conditions from what you did those at the Omaha 

 Exposition last year. So far they are doing very finely, very 

 nicely indeed; but whether we are to succeed in raising many 

 of them or not I can not say as yet. They are taking food. We 

 are feeding them finely chopped liver. 



President Peabody: Would you advise putting grayling in 

 a stream where there are brook trout? 



Mr. Clark: Well, you cannot hurt the brook trout any, but 

 it is a question, of course about the grayling. 



President Peabody: Whether you would waste your gray- 

 ling or not? 



Mr. Clark: Yes, whether you would waste your grayling 

 or not. I have planted half of these in the Au Sable River and 

 half in the Pere Marquette River, two old grayling streams, 

 both having brook and rainbow trout now. 



President Peabody : In regard to the temperature, a stream 

 that is too warm for brook trout is all right for rainbow trout. 

 How is it about the gravlinu?
