LIFE HISTORY AND HABITS 



but at times I have been unable to see any changes 

 in the pools at all. I believe it is caused by the 

 first run of fish having stopped in the pools due to 

 daylight overtaking them as they were travelling

 I know a number of instances of this, but it may

 in bunches, up to about ten or eleven o'clock in
