FOR PLEASURE AND PROFIT. 153 



Bolton, and Aquila Hancock, of Deritend Bridge, Birming- 

 ham. 



Under any circumstances, your dams and banks must be 

 kept free from the inroad of the furred enemies to fish-life, 

 and the fish themselves from the attentions of their feathered 

 foes. And do not forget that mice are very destructive to 

 fish eggs. A well-trained dog is a useful friend at any fishery. 



In conclusion, I would tender the old advice " If at first 

 you don't succeed, try again " ; and, with the exercise of 

 some common-sense on your part, you will soon be able to 

 farm fish for profit, and will assuredly derive pleasure from 

 the pursuit of fish-culture.
