MIGRATION 



water-fowl, they are often borne inland, and if the bird to whose crop they 

 have been consigned is killed, they may be left to grow up from the sea. 



" A deer has strayed from the herd, when browsing in some rich pasture, 

 when he is suddenly alarmed by the approach of his foe. He instantly takes 

 to flight, dashing through many a thicket, and swimming across many a river 

 and lake. The seeds of the herbs and shrubs which have adhered to his 

 smoking flanks and even many a thorny spray, which has been torn off and 

 has fixed itself in his hairy coat, are brushed off again in other thickets and 

 copses. Even on the spot where the victim is devoured many of the seeds 

 which he had swallowed immediately before the chase may be left on the 

 ground uninjured and ready to spring up in a new soil.'' 



Any one accustomed to keeping, in cages or aviaries, 

 birds that are migratory, knows full well the season in 

 which the habit of migration takes place ; the birds that 

 are perfectly tame and reconciled to captivity, all at once 

 become uneasy and restless, fly about the cage, jumping 

 and dashing here and there the whole night through, 

 calling aloud, and almost ceasing to take food, and for 

 several days and nights this determination to depart will 

 sometimes last. Strange to say the same thing again 

 occurs at the season to return to this country; but in 

 this case the restlessness is much less severe and is soon 

 over. Year after year this same desire to migrate is 

 manifested by the same birds.
