ino-. As soon as the umbilical sac was absorbed, I 

 deposited a large portion of them in Au Sable river — 

 a beautiful, clear and rapid stream of water which 

 empties into Lake Huron, near Thunder Bay. This 

 was about May 20th — temperature of water 60 

 degrees. 



These salmon have been caught and samples of 

 them sent, by D. H. Fitzhugh, Esq., of Bay City, to 

 Prof. Baird, who pronounced them genuine Penob- 

 scot salmon. These two opposite results, as relat- 

 ing- to the Atlantic and Pacific salmon, indicate 

 plainly that the former have fallen into waters con- 

 genial to them, while the latter, it is to be feared,, 

 have perished through the unnatural circumstances, 

 they have been forced to occupy. 



In conclusion, I call especial attention of scienti- 

 fic and practical fish-breeders to the ideas herein 

 suggested. For my part, I have been guided to the 

 views I have endeavored to present, by the experi- 

 ments of a humble seeker after true and rational 

 methods of advancing- what I can but feel is alreadv 

 and destined to become a more and more important 

 branch of industry in this country. Hoping that 

 what I have presented will tend to awaken a more 

 general interest among you on this subject, and 

 thanking you for the opportunity you have accorded 

 me of addressing you, I close.
