Mr. Clark: 1 wouUl Hke to state further that Air. I lower sent 

 down to Xorthville a eertain nunil)er of adult grayling, and among 

 them I found a ripe one the same day they arrived. VVe took 

 the eggs from that fish and they amounted in nunil)er to a little 

 over 5.000. 



Mr. Peabody: Your e.xperienee in Michigan is that it is not 

 profitable to raise them? Have you succeeded in doing it to any 

 extent? 



Mr. Clark: We have not succeeded well with them. 



Mr. W'hitaker: 1 haven't any doitbt in my own mind that 

 there are marked ditTerences in the habits as well as the character 

 of gravling in localities remote from each other. The European 

 grayling and the American grayling dififer. and very likely there 

 are differences between the grayling of Montana and the grayling 

 of Michigan. 



The streams lying in the u])i)er half of the lower penin- 

 sula of ]\lichigan originally contained nothing but grayling 

 and the fish were so plentiful that a lady living at Reed City told 

 Dr. Parker, a former member of our Board, that she had seen 

 farmers come there at the time of grayling spawning, and from 

 under the apron of the dam, with an ordinary pitch-fork, fill a 

 small wagon-box with g^rayling. The grayling, however, have 

 practically disappeared from nearly all our streams. I have 

 come to the conclusion from my experience that their decadence 

 is chiefly owing to the fact that the spawning season, coming as 

 it does, just before the breaking up of the ice in the rivers, filled 

 as they are with logs, it follcnvs that the logs plow up the beds 

 and destroy the eggs, and that log-nmning is responsible for the 

 disappearance of these fish from t)ur streams. I introduced a 

 resolution in the Michigan Pioard of Fish Commissioners at one 

 of its meetings in 1878 to stop the further planting of brook trout 

 in grayling streams and their tributaries. I urged that it was not 

 policy to cease trying to propagate the grayling, and that we 

 should make some experiments looking to the planting of the 

 grayling in waters in wliich they were indigenous. We passed 

 the resolution and such ste])s were taken. We snbse(|nentl\- or-
