difPerence between them and the Michigan grayling. At earlier 

 stages in their life, the first ones that we hatched, I doubted very 

 much if they were grayling, although I do not know whether I 

 corresponded with Washington in regard to the matter or not, 

 but I think I spoke to ]\Ir. Eavenel on the subject, saying that 

 I thought the doctor had crossed them with trout, they were so 

 spotted. Michigan grayling have no trout markings, but the 

 Montana grayling have, and you can see them in Xortliville at 

 the present time. 



In regard to the steelhead trout, I will answer, so far as 

 Michigan is concerned, that we have been planting them there 

 for quite a while, and all those that have been caught are very 

 large fish. One was sent to the Washington office this last win- 

 ter which I think weighed seven pounds. There is one being 

 mounted in Detroit that was caught near Traverse City that 

 weighed twelve pounds, eight ounces; and there have been a 

 number of other cases of this kind. The one that was forwarded 

 to Washington I saw upon arrival. They seem to be cauglit in 

 the great lake waters, or near-by, and my impression is that they 

 are going to use Lakes Michigan, Huron and Superior, the same 

 as they use the sea in their native country. 



We have had remarkable success this year in tlie impregna- 

 tion of the eggs, that is, getting a good quality, and I tliink that 

 something like 90 per cent of good eggs w^ere obtained from the 

 fish, which w^e do not have from the rainbow trout. 



Mr. Titcomb : You mean the domesticated fish ? 



A. Yes, sir. 



Dr. Bean : I would like to say a word on Dr. Henshall's 

 paper. The Montana grayling is not the same species as the 

 Michigan grayling. It foUows tlie usual rule among the gray- 

 lings in that the very young have parr-marks. I do not know 

 about the Michigan graylings. Mr. Clark has been in a much 

 better position to learn than I. l)ut speaking now as an ichthyolo- 

 gist and from book laiowledge chiefly, I sav that the young gray- 

 ling ought to have parrmarks: the :\Iontana grayling has them, 

 the European species has tlicm : the :\[ontana grayling lias a very 

 much smaller fin than the Michigan grayling: its dorsal fin is 

 shorter and lower; its head is smaller, and in other ways it is 

 very easily distinguished from the Michigan grayling, so tliat
