2i6 THE TROUT 



some of them now are not far short of Ib. in weight. 

 It is an interesting fact that those which inhabit the 

 bed of the old brook, the waters of which have been 

 raised by dams and which swarm with freshwater 

 shrimps, are almost as pink as salmon, while those 

 which have been placed in a stream which runs 

 through a newly made bed, and which are more 

 dependent than the others on the fly, are nearly pale 

 yellow. This seems to bear out what Francis Francis 

 used to say as to pink flesh being due to freshwater 

 shrimp.' 



My correspondent's observation also furnishes a 

 striking commentary on a passage in Walton's c Com- 

 plete Angler,' ' If I catch a trout in one meadow, he 

 shall be white and faint, and as certainly if I catch a 

 trout in the next meadow, he shall be strong and red, 

 and lusty, and much better meat.' 



One more word before I take leave of Gammarus 

 Pulex. He follows a humble but useful calling, 

 which has endeared him to the fish-culturist. He is 

 an indefatigable scavenger. 



Trout-water can also be usefully stocked with the 

 larvae of various insects which are more familiar to us 

 in the winged stage of their existence. At the head 

 of the list of these larvae you will not be surprised to 

 find that of an old familiar friend, the Mayfly.
