18 THE WONDERFUL TROUT 



season arrived, and then rapid decadence. Of 

 this subject we may have more to say under 

 a later chapter, and when we come to speak 

 more pointedly of food supplies. 1 



New revelations have been made as regards 

 the life-history of the eel in salt water, since 

 this part of our writing was done. 2 We 

 believe that our Salmon Commissioners have 

 almost as much to learn as regards the life- 

 history of our migratory fish in salt water ; 

 and that quite as interesting, and even 

 startling, results may yet be revealed.
