NATURALIZATION OF FISH. 149 



In the interior of Sweden, where access to fish is not 

 always easy, much store is set by the cray-fish, and it fre- 

 quently constitutes a principal dish at the feast. 



Various devices are adopted to effect its capture ; but it is 

 often taken with rod and line, in which sport the fair sex 

 occasionally take part ; and I have known ladies, young as 

 well as old, recount with much glee their exploits in this 

 way. 



It is a pity that more frequent attempts are not made to 

 introduce into England fish that are foreign to our Fauna. 

 That there are no insurmountable obstacles in the way, is 

 evinced by the decided success achieved by the late Earl of 

 Derby. Under date of the 24th of February, 1848, his 

 Lordship wrote me from Knowsley Park as follows : 



" You ask me if I take as much interest in the finny tribe 

 as in the feathered race. I cannot say as much ; but I have 

 lately succeeded in introducing into our water here several of 

 the fish from other parts of the island. I have brought Trout 

 from Islay in Scotland, Gwyniad from Wales, and Charr 

 from Westmoreland, and have even brought as many as over 

 four hundred, without losing more than the odd surplus .... 

 I have had some thoughts of sending my fisherman over into 

 Germany for the purpose of trying to obtain, and to convey 

 over the Channel some of their most esteemed fish, such as 

 the golden or Prussian Carp, the Pike-perch, and two or 

 three others. Are there any in your vicinity that would be 

 desirable and worthy of being transported, not to New 

 South Wales, but to Old England ? If my man could meet 

 with anything like the success he has hitherto had in this 

 way, in Great Britain, I should have no fears about being 

 ablf in a short time to establish them here."
