carried. Two years ago a number of adult grayling were pro- 

 cured by the Micliigan Commission, and placed in the trout 

 ponds of Paris. Out of the number not a single fish has ever 

 spawned or showed the slightest inclination to do so. They 

 have gradually died, and there are now but a very few remain- 

 ing. The same care and attention has been given the grayling 

 in'these ponds that is ordinarily given to trout. 



About the year 1878, Mr. Ira Metcalf, of Battle Creek, Mich., 

 made some attempts at artificial propagation of the grayling, 

 and claims to have been successful in raising a small amount of 

 fry. 



An instance illustrating the prolific character of the grayling, 

 Mr. George H. Jerome, formerly superintendent of the Commis- 

 sion, states in his report that in transporting the first grayling 

 taken to the station from the Manistee, it was observed by the 

 men having charge of the fish while /// transitu, that there was a 

 fully ripe spawner in one of the cans ; that she was removed 

 and the eggs taken, but there being no milter with which to 

 fertilize the ova, they were lost ; that the eggs after being taken 

 were counted by two reliable persons, and there were found to 

 '^e 3,555 fully developed perfect eggs. The fish after being 

 stripped weighed exactly 9 oz. This shows beyond question 

 th It the grayling is much more prolific than the trout, and under 

 favorable circumstances good results should certainly be ob- 

 tained. 



The Michigan Commission has within the last year acquired 

 the ownership of a fine spring stream upon property adjoining 

 its trout station, to which the grayling had been natural, one or 

 two having been taken in the stream within a year. This prop- 

 erty affords opportunity for extended experiments looking to 

 the solution of the question of whether the grayling may be 

 successfully propagated. Arrangements are now being made to 

 secure an ample supply of stock fish, which will be held in this 

 stream in such a manner that the confinement will be felt as 

 little as possible consistent with control. As far as possible the 

 natural conditions of the stream will be preserved ; pool and 

 sliallow, light and shade. At the same time care will be taken
