several were hanging in limp, grotesque, horribly suggestive attitudes of death. Manuel had all of the Indian's leaning toward the mystical, and he believed the rabihorcados had destroyed themselves. Starved they may very well have been, but to me the gales of that wind-swept, ocean desert accounted for the hanging rabihorcados.
Still, when face to face with the island, with its strife, and its illustration of the survival of the fittest, all that Manuel had claimed and more, I had to acknowledge the disquieting force of the thing and its stunning blow to an imagined knowledge of life and its secrets.
Suddenly Manuel shouted and pointed westward. I saw long white streams of sea-birds coming toward the island. My glass showed them to be boobies. An instant later thousands of rabihorcados took wing as if impelled by a common motive. Manuel ran ahead in his excitement, turning to shout to me, and then to point toward the wavering, swelling, white streams. I hurried after him, to that end of the island where we had landed, and I found the colony of boobies in a state of great perturbation. All were squawking, flapping wings, and waddling frantically about. Here was fear such as had not appeared on my advent.
Thousands of boobies were returning from deep-sea fishing, and as they neared the island they were met and set upon by a swarming army of rabihorcados. Darting white and black streaks crossed the blue of sky like a changeful web. The air was full of plaintive cries and hoarse croaks and the windy rush of wings. So marvelous was this scene of incredibly swift action, of kaleidoscopic change, of streaking lines and curves, that the tragedy at first was lost upon me. Then the shrieking of a booby told me that the robber birds were after their prey. Manuel lay flat on the ground to avoid being struck by low-flying birds, but I remained standing in order to see the better. Faster and faster circled the pursued and pursuers and louder grew the cries and croaks. My gaze was bewildered by the endless, eddying stream of birds.
Then I turned my back on sea and beach where this bee-swarm confused my vision, and looked to see single boobies whirling here and there with two or three black demons in pursuit. I picked out one group and turned my glass upon it. Many battles had I seen by field and stream and mountain, but this unequal battle by sea eclipsed all. The booby's mother instinct was to get to her young with the precious fish that meant life. And she would have been more than a match for any one thief.
But she could not cope successfully with two fierce rabihorcados; for one soared above her, resting, watching, while the other darted and whirled to the attack. They changed, now one black demon swooping down, and then the other, in calculating, pitiless pursuit. How glorious she was in poise and swerve and sweep! For what seemed a long time neither rabihorcado touched her. What distance she could have placed between them but for that faithful mother instinct! She kept circling, ever returning, drawn back toward the sand by the magnet of love; and the powerful wings seemed slowly to lose strength. Closer the rabihorcados swooped and rose and swooped again, till one of them, shooting down like a black flash, struck her in the back. The white feathers flew away on the wind. She swept up, appeared to pause wearily and quiver, then disgorged her fish. It glinted in the sunlight. The rabihorcado dropped in easy, downward curve and caught it as it fell.
"You have guessed right; I have lately been so deeply engaged in one occupation that I have not allowed myself sufficient rest, as you see; but I hope, I sincerely hope, that all these employments are now at an end and that I am at length free."
As we rowed away I looked back. Sky of a dull purple, like smoke with fire behind it, framed the birds of power and prey in colors suitable to their spirit. My ears were filled with the haunting sound of the sea, the sad wash of the surf, the
