arduous competitions which annually take place among 
first-rate birds. As soon as the fledgling is fairly strong 
on its wings, it is taken a few miles from the cot and 
released. It rises into the air, looks about it and starts 
straight away for home. There is no mystery about this 
at all; when it has attained the height of a few yards the 
bird can see its cot, and full of that strong love of home 
which is so characteristic of its wild ancestors, the blue-rocks, 
it hastens back to the society of its mates. The next day 
the trial-distance is doubled, and the third day is still fur-

distance of seventy miles, which is all that a bird-of-the- 
year is “fit” to do; and when two years old, will return 
from two hundred miles, longer distances being left to 
more mature birds. but all this training must be in a 
continuous direction; if the first lesson was toward the 
east, subsequent lessons must also be; nor can the added 
distance each time exceed a certain limit, for then, after 
trying this way and that, and failing to recognize any 
landmark, the bird will simply come back to where it was 
thrown up. Moreover, it must always be clear weather. 
Homing pigeons will make no attempt to start in a fog, or

lost. Nor do they travel at night, but settle down at dusk
