I know not how the stork, "leaning upon the sirocco," makes a leverage of the opposing element for her swift flight. I leave the naturalist to explain that. But I do know that the sirocco is a challenge to her unerring instinct and strength of wing. God manipulates the wind. The stork manipulates her wings. And the working of the combination results advantageously to the stork. She does not lean upon the sirocco wind as you would lean upon a couch. That would result in a fall and the bird would be dashed to pieces. The leaning is accompanied by action. While the buoyancy of the air bears her up, the balancing of the wings bears her on. That air-cushion is no "downy bed of ease." It is a thing to be encountered and overcome. She makes the adversary contribute to her progress. The thing from which men shrink is the thing the bird dares.--C. J. Greenwood.
