208 FISHERMEN'S WEATHER 



Storms

waterways. 



and those "tempests," so called, which 

 pass out to sea, was cited in the Intro- 

 duction, and needs no further notice. 

 Mr. Champneys points out that the 

 prophetic instinct, which so often enables 

 fresh-water fishes to foretell the coming 

 of a thunderstorm, looks like a survival 

 from a marine habitat, where alone such 

 prescience would be needed to enable 

 them to take shelter from the violence 

 of the waves. No such danger threatens 

 them in rivers, yet they appear to have 

 retained the protective instinct, even 

 where it is to some extent supererogatory. 

 The influence which thunderstorms 

 may have on fishing gains added interest 

 from the well-established fact that these 

 phenomena follow canals and other water- 

 ways. From observations made on the 

 Kaiser Wilhelm Canal by German 

 officials connected with the Meteoro- 

 logical Survey, this tendency seems 

 entitled to general recognition.
