EFFECTS OF WEAKENING THE SHOALS. 177 



•work accomplislied ■ by these natural enemies of the herring, 

 which has been going on during all time, does not however 

 affect my argument, that by the concentration on one shoal of 

 a thousand boats per annum, with an annually-increasing net- 

 power, we both so weaken and frighten the shoal that it becomes 

 jn tin^e unproductive. As the late Mr. Methuen said in one. of 

 his addresses: "We have been told that we are to have 

 dominion over the fish of the sea, but domiaion does not mean 

 extermination."
