INSTINCT IN ANIMALS.


Change Their Homo with the Seasons.
To the older philosophers instinct was
a far more wonderful thing than it APP
pears now. They asserted that all the
actions of the lower animals were per-
formed through instinct, and explained
that they possessed this faculty in lieu
of intelligence, which was the peculiar
attribute Of man. This was. however,
soon exploded by the demonstration Of
the possession Of intelligence among
animals and Of instinct by man. In
deed the later philosophers have come to
believe that almost all the actions Of
man are influenced if not controlled by
instinct alone.
The tendency to migration of certain
species of animals is plainly referable TO
this hereditary influence. Originally,
no doubt, migration occurred because
food was more easily found in one To-
cality than in another. The hereditary
memory, so to speak, pointed out the
place where more food was TO be OBJ
tanned with less exertion. Gradually
other surroundings suggested themselves
as agreeable to the embryo mind, and
and these, repeated through many gem
erations, created that unthinking tend
ency toward a particular place or eli
mate regardless Of its original fitness.
Almost all our ideas are gained from
association, and it is fair to imagine that
the constant and repeated association Of
q particular locality, with a pleasurabie
sensation-the satiatiOn of hunger, for
would soon identify the sem
sation with the place. Then would be
evolved the sentiment of home, a senti-
ment which we feel only more keenly
than the lower animals because it is as
sociated not only with the place where
there is something to eat, but because
of other pleasurable sensations associated
with it, as they are as constantly found
in the same locality.
1t is a mistake to regard the migratory
instincts of animals as unerring. Every
woodsman has observed how a particu-
lar species OF bird viii apparently desert
a certain locality for another for one on
more seasons. Occasionally TINS may
result from choice, but it seems alto
gether more probable that it is from
some mistake ON the part Of the birds
themselves. Their generally accurate
course has been DETECTED by some cir
cumstance, and they have made then
homes elsewhere. In the case OF strag-
glers this is particularly marked. They
rarely succeed in rejoining the main
body to which they originally belonged
and are forced to be content with what
ever suitable place may be found.
Migratory animals and birds are al
most always gregarious-that is, they
live and especially they travel in com
pact flocks or herds. They do this fol
