 ciently strong to affect the surface of the 

 water; on the other hand sudden and loud 

 thunderclaps produce concussions that alarm 

 the fish, causing them to scurry to a place of 

 safety. 



This subject of thunder-storms affecting the 

 rising of trout, naturally suggests a few words 

 on the effects of other atmospheric conditions. 

 For instance, as to what wind is most favorable
