ATTITUDES EXPRESSING EMOTION 9 



time the next day I photographed him as shown in the 

 illustration, when he was after a roach, so that within 

 eighteen hours of being turned into the pond he was 

 quite at home, and had apparently forgotten his un- 

 pleasant experience of the previous day. 



If a trout is hooked and the fly breaks off in his 

 lip, the same fish can be caught with another fly within 

 an hour, and the first fly recovered These two examples 

 point to the fact that an unpleasant incident makes 

 very little impression ; but a large trout marked down 

 at a certain spot, and pricked with a fly on two or three 

 occasions, becomes shy and rises short, and should he 

 be pricked a few times more he will knock off feeding on 

 the surface altogether. 



The first few pricks made him remember to tackle 

 a fly with care, and the continued pricking was sufficient 

 to remind him for several days to keep off fly altogether. 



Curiosity is strongly developed in fish. This is 

 mainly due to the fact that they have continually 

 to search for food, yet if a new piece of rock is put in a 

 tank, fish will swim round and round, and under it, and 

 thoroughly examine it, whereas the first inspection 

 would show that it contained no food. Curiosity may 

 also explain why fish take many of the quaint lures 

 offered to them. Affection is a quality that fish do not 

 possess. At the breeding season they certainly are 

 attentive, and many fish protect and defend their eggs 

 and offspring, but this subject is dealt with in the next 

 chapter.
