do not as a rule come actually with them. Weseem, 
therefore, forced to assume that there is some inborr 
faculty—whether we call it instinct or not, matters 
little—-which guides them. The sense of direction 
varies infinitely among men. One man, to use an 
Americanism, is very easily “turned round,” another 
never gets confused about the points of the compass 
and can always find his way home. Most civilized 
races have toa great extent lost this power, but the 
Swiss guide has it in a high degree. In savages it is 
often developed to a wonderful extent, and in some 
animals it is still more remarkable. A dog, when he 
is taken far from home, though he is shut up so that 
he cannot see where he is going, will often find his 
way back. A Homer Pigeon is put in a basket and 
without a chance of using his eyes is whirled along 
in the train to some distant place. When set free, he 
flies aloft, takes his bearings and sets off homeward. 
I cannot understand why Professor Newton has given 
up the opinion he had once formed, that we have in 
the “homing” faculty of Pigeons a hint as to the 
power by which a migratory bird finds his way. It is 
true, as he says, that the Pigeon depends largely upon 
sight to find the exact spot where his home lies. But 
those which flew from Rome to England cannot have 
depended upon the sense of sight alone. The cir- 
cumstances of the Pigeon and the young migrant are 
not the same. The former is a trained specialist and 
finds his way to a place he is familiar with, the latter 
‘is young and inexperienced and has to steer for a place 
he has never seen. Still each depends, not on land- 
marks, but on some inborn faculty or instinct, to teach
