REPORT ON ARTIFICIAL FISH-CULTURE. 49 



other fish of limited supply, I would not attach 

 as much interest to it as I do; but it may be 

 applied to salmon, and I am convinced that it 

 would be easy thus to restore to the rivers of 

 Brittany icthyological riches which are now dis- 

 appearing, and even to acclimate salmon in rivers 

 which, up to this time, have not been frequented 

 by that fish. 



Nothing is easier than to transport eggs just 

 laid, or living salmon of which the abdomen is 

 filled either with eggs or milt; and even when 

 these die on the road, the hatching of their eggs

 in streamlets properly chosen, the young salmon 

 will grow as though spawned there by their par- 

 ents ; they will emigrate as usual to the ocean, 

 and in its depths they in turn will spawn, and 

 will not fail to return in great numbers to the 

 stream whence they proceeded, and in following 

 its course seek a proper place for the growth of 

 their progeny. 



We know, in fact by experiments already old, 

 made in Brittany by Delandes, and by observa- 

 tions of the same kind, repeated in our day in 

 Scotland by the Duke of Athol, Sir W. Jardine, 

 Mr. Baigrie, Mr. Hayshan and Mr. Young, the 

 Director of the fisheries of the Duke of Suther- 

 land, that guided by a singular instinct comparable
