RUE WITH A DIFFERENCE 101 



remember what a strange and striking event the 

 rearing of a young cuckoo must be in the life of a 

 small bird, at least the first time it : oecurs. v The 

 smell, also, would not be that of its own ^ 

 that there would be more than appearance -to 

 guish it. In fact, the thing having been peculiar, 

 the feelings aroused by it may have been stronger, 

 in which case the memory might be stronger too, 

 and revive these feelings, or, at least, it might

 once begun, continues, so that it is, now, as 

 much the thing to mob the one as the other. Be 

 this as it may, I do not think that hawks suffer 

 from this sort of annoyance, to anything like the
