114 SALMON FISHING 



allow salmon to live in it once again ; was it to 

 be thought that this example had been neglected 

 everywhere ? 



Why not put those questions to a test? Why 

 not make a survey of the main rivers in the United 

 Kingdom ? 



I have done so. The results will be found in 

 chapters immediately following. The information 

 set forth, it will be noticed, is in all cases given on 

 authorities that are unquestionable. In another 

 chapter, on Storage and Passes, I will discuss the 

 chief fact brought out in our survey of the rivers. 

 My endeavour will be to show that all the troubles 

 disclosed are ultimately due to a single condition, the 

 want of a natural, equable flow ; and that for this 

 condition a remedy has been found. Meanwhile I 

 may perhaps venture a belief that salmon fishing 

 is now, as grouse shooting seems to have been fifty 

 years ago, a sport only beginning to be scientifically 

 understood and systematically cultivated.
