FOOD-SUPPLIES AND RELEVANT MATTERS 119 



more active ones are getting a chance to 

 feed, and take advantage of it ; while larger 

 but imperfect-conditioned fish also take the 

 chance given by the refusal of their stronger 

 neighbours. 



There are many bad days when only small 

 or badly fed trout are found to be on the 

 move, and thus we account for it. We feel 

 pretty sure we are not far wrong, as we make 

 our analyses and averages pretty carefully. 



Trout feel warm or cold in the hand when 

 taken out of the water. This, surely, almost 

 all anglers must have noticed, and on those 

 days when they feel cold, i.e. colder than 

 human-blood temperature, it is usually (we 

 think we are correct) when the temperature 

 of the air is very much warmer than that of 

 the water, and usually on such days they do 

 not rise well. 



Temperatures of air and water. We have 

 rarely found trout rise well when the follow- 

 ing temperatures are found to rule (and we 

 here refer our readers to our Tables, showing 

 some of these rulings, and to the Tables which 

 illustrate day-to-day records, which are taken 

 direct from our regular fishers' registers).
