The Tribe of the Sea Sivallows 



all ages, the migrating instinct proving stronger than the 

 parental one. 



But I do not think their migration is a hurried one, 

 like that of the birds which have difficulty in obtaining 

 food on their journey; for the sea swallows appear to make 

 their way leisurely along the coasts, feeding on the sand 

 eels as they go, and gradually reaching those southerly 

 regions where, with the sun shining warm and the sea blue 

 and unruffled, they will pass the winter months till the call 

 of summer once more brings them north to their well-loved 

 nesting-grounds.
