188 A PHILOSOPHER WITH NATURE 



amongst the swallows does not calm down for a long 

 time. 



The great city grows apace and the feathered 

 tribe retires steadily before it. Even our parks 

 and open spaces do not seem to tempt the birds to 

 linger with us. The nightingale still sings on 

 Hampstead Heights, and the blackbird pipes on the 

 fringes of Clapham Park ; but even there they are 

 in retreat before the speculative builder. Only 

 the sparrow and the pigeon remain with us.
