 cannot vouch that they would retam their delicate 

 flavour. 



After the fish ahove noted I should place the pike

 their room being in such places far better than their 

 company. There are many rivers, however, of a 

 mixed character, where they are found in great 

 abundance, and where they manage, owing to the 

 varied character of the water of the rivers, to do well 

 enough together, though even here the more delicate 

 fish caimot but suffer severely from them; these 

 are, however, usually large rivers : in small ones, if 

 largely introduced and left to themselves, they would

 they do so exist, however, and are looked upon by 

 many as affording a wide range of sport, they must 

 be considered accordingly. In such cases I would 

 recommend artificial breeding of better fish to be 

 carried on largely as the only means of coping with 

 the coarser species. 



Many rivers, again, are merely white or coarse 

 fish rivers, unadapted to salmon and trout ; and as
