[PURIFICATION.]
In the morning—not at the first blush of dawn, but when the sun already mounts the horizon—and at the very moment when the cocoa-nut tree unfolds its leaves, the urubus (or little vultures), perched in knots of forty or fifty upon its branches, open their brilliant ruby eyes. The toils of the day demand them. In indolent Africa a hundred villages invoke them; in drowsy America, south of Panama or Caraccas, they, swiftest of cleansers, must sweep out and purify the town before the Spaniard rises, before the potent sun has stirred the carcass and the mass of rottenness into fermentation. If they failed a single day, the country would become a desert.
When it is evening-time in America—when the urubu, his day's work ended, replaces himself on the cocoa-nut tree—the minarets of Asia sparkle in the morning's rays. Not less punctual than their American brothers, vultures, crows, storks, ibises, set out from their balconies on their various missions: some to the fields, to destroy the insect and the serpent; others, alighting in the streets of Alexandria or Cairo, hasten to accomplish their task of municipal scavengering. Did they but take the briefest holiday the plague would soon be the only inhabitant of the country.
Thus, in the two hemispheres, the great work of public health is performed with solemn and wonderful regularity. If the sun is punctual in fertilizing life, these scavengers—sworn in and licensed by nature—are no less punctual in withdrawing from his rays the shocking spectacle of death.
Seemingly they are not ignorant of the importance of their functions. Approach them, and they will not retreat. When they have received the signal from their comrades the crows, which often precede them and point out their prey, you will see the vultures descend in a cloud from one knows not whence, as if from heaven! Naturally solitary, and without communication—mostly silent—they flock to the banquet by the hundred, and nothing disturbs them. They quarrel not among themselves, they take no heed of the passer-by. They imperturbably accomplish their functions in a stern kind of gravity; with decency and propriety; the corpse disappears, the skin remains. In a moment a frightful mass of putrid fermentation, which man had never dared to draw near, has vanished—has re-entered the pure and wholesome current of universal life.
It is strange that the more useful they are to us, the more odious we find them. We are unwilling to accept them for what they are, to regard them in their true rôle, as the beneficent cressets of living fire through which nature passes everything that might corrupt the higher life. For this purpose she has provided them with an admirable apparatus, which receives, destroys, transforms, without ever rejecting, wearying, or even satisfying itself. Let them devour a hippopotamus, and they are still famished. To the gulls (those vultures of the sea) a whale seems but a reasonable morsel! They will dissect it and clear it away better than the most skilful whalers. As long as aught of it remains they remain; fire at them, and they intrepidly return to it in the mouth of your guns. Nothing dislodges the vulture on the carcass of a hippopotamus. Levaillant killed one of these birds, which, though mortally wounded, still plucked away scraps of flesh. Was he starving? Not he; food was found in his stomach weighing six pounds!
