As the migrating birds are beginning to arrive in the Southern States, and will soon be North, let us consider the subject of migration. The reason why birds migrate North in the spring is not definitely-known. Of course they leave the North because cold and snow cut off their food supply; but why in the spring do they abandon a country where food is plentiful and make such long flights, apparently for no other object than to bring forth their young in the North?

Is it not wonderful how birds find their way, over thousands of miles of land and water, to the same locality and often to the same nest, season after season? How do we know that this is true? The reappearance of a bird with a crippled foot or wing, or one that has been tamed to feed from one's hand, is unmistakable proof.
February Twenty-first
Ducks and geese make longest flights of any of the migrating birds. They have been known to cover three hundred miles without resting. The smaller birds advance as the season advances, the early arrivals being the ones that do not winter very far south. Storm-waves often check their progress and compel them to turn back a few hundred miles and wait for the weather to moderate.
