Hovering over and about the tall masts upon untiring pinions, a score of white-winged, graceful marine birds persistently kept us company day after day. They joined the ship off the coast of Sumatra, as we left the entrance to the Malacca Straits, introducing themselves at first with noisy vehemence and piercing cries, as if to assert their presence and purpose, a proceeding which was not again repeated. What became of these handsome feathered creatures at night we never knew, and it was found that the oldest seaman was equally ignorant. If they slept upon the waves, they must have overtaken us with arrowy swiftness at the break of day. They were undoubtedly able to do this, as they outstripped us in speed at any moment when they chose to do so, sailing through the air far ahead and all around the rapid, steady-going ship. However early one came on deck, they were sure to be in sight, glancing hither and thither upon the invisible air currents without any apparent exertion. It was the very poetry of motion. We came finally to look upon these tireless fellow travelers with no small degree of interest, and should really have regretted their absence. It is always a pleasing diversion to watch them, to count and see that their full number is still present, and to delight in their free and graceful movements.
During the period of their presumed nightly rest upon the heaving bosom of the sea, our vessel must necessarily pass over a distance of many leagues, far, far beyond the power of human sight. How marvelous, therefore, must be the instinct which guides them unerringly to resume our company with the earliest rays of the morning light. When, in the arid desert, the exhausted camel sinks at last in its tracks to die, and is finally left by the rest of the caravan, no other object is visible in the widespread expanse, even down to the very verge of the horizon. Scarcely is the poor creature unloaded, however, and left to perish upon the sand, before there will appear in the far-away sky a cloud of vultures, at first mere specks in the blue atmosphere, swooping with lightning speed towards the dying animal, whose bones they immediately strip with terrific voraciousness. One who has witnessed this scene can never forget it. The vultures strain and tear at the carcass, swallowing great pieces of hide and flesh, until at last, when they are completely gorged, they can only rise a few feet from the earth, to sink again exhausted upon their feet. Hours must transpire before they can again soar any distance upon the wing, after their gluttonous repast.
