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 Lis 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.
