It is true that man makes longer journeys than birds do. But it is also true that he could not make them without help from other men. He might walk where there was land, but he would need days to go as far as a bird could go in an hour. And when he comes to the sea he requires a sailing vessel or steamer with charts and maps and compass to aid him in finding the way; while in the hold there must be food for the use of the crew and passengers during the voyage. But the bird traveler asks help from no one. He has no use for locomotives, automobiles or steamships. He carries no chart and no com pass, and he can go with ease to parts of the world which it took man many years to reach, and to some parts Of the world which still are unknown to man.
