FIFTEENTH ANNUAL MEETING. 65 



to time suggest themselves, based on present knowledge, and 

 such information as may be obtained by a careful observation 

 of tlieir habits. The experiments will extend over a sufficient 

 period of time, and be followed up by earnest endeavor, until it 

 shall be definitely determined wiiether successful propagation of 

 the grayling can be carried out. 

 Detroit, Mich. 



Mr. May. — I notice that Mr. Whitaker credits Mr. Metcalf 

 with hatching grayling in 1878. I have seen in Prof. Goode's 

 " Epochs in Fish Culture," that Fred Mather hatched the first 

 grayling in 1874, just four years previous to Mr. Metcalf. 



Mr. Clark. — I think the grayling is the easiest fish to propa- 

 gate and handle of any fish we had anything to do with, after 

 we get the fish. Mr. Whitaker doesn't say this in his paper, 

 but I will say that if a person can get the fish on the stream 

 they can get five hundred thousand fish, which they can handle 

 for one quarter of the cost of brook trout. 



Mr. Fairkank. — How long are they in hatching .'' 



Mr. Clark. — From seventeen to twenty-five days. They are 

 easy to handle. The fish are easy to take care of after they are 

 hatched, and you can grow a greater per cent, of them than you 

 can of trout. 



A Member. — Don't they require much cooler water. 



Mi. Clark. — I think you can put trout in a natural stream of 

 warmer water than you can the grayling. 1 liaven't tried the 

 experiments on that. I got about twenty-five thousand eggs 

 last spring from six or eight fish. A fish that weighed one and 

 a quarter pounds we took five thousand two hundred eggs from. 

 All we had to do was to get the fish, and you give me a thousand 

 graylings, and if I don't take you over a million eggs I will miss 

 mv guess. 



Mr. Fairp.ank. — It is difficult to get the fish at that season of 

 the year. 



Mr. Clark. — It is difficult to get them, because the streams 

 are fished out. Tiie streams are not high, not at that time. You
