Thrice had they caught fleeting glimpses of great man-like figures like that of the first night, but never at sufficiently close range to know positively whether the half-seen forms were those of man or brute.
The brilliant birds and the little monkeys had become accustomed to their new acquaintances, and as they had evidently never seen human beings before they presently, after their first fright had worn off, approached closer and closer, impelled by that strange curiosity which dominates the wild creatures of the forest and the jungle and the plain, so that within the first month several of the birds had gone so far as even to accept morsels of food from the friendly hands of the Claytons.
One afternoon, while Clayton was working upon an addition to their cabin, for he contemplated building several more rooms, a number of their grotesque little friends came shrieking and scolding through the trees from the direction of the ridge. Ever as they fled they cast fearful glances back of them, and finally they stopped near Clayton jabbering excitedly to him as though to warn him of approaching danger.
At last he saw it, the thing the little monkeys so feared—the man-brute of which the Claytons had caught occasional fleeting glimpses.
It was approaching through the jungle in a semi-erect position, now and then placing the backs of its closed fists upon the ground—a great anthropoid ape, and, as it advanced, it emitted deep guttural growls and an occasional low barking sound.
Clayton was at some distance from the cabin, having come to fell a particularly perfect tree for his building operations. Grown careless from months of continued safety, during which time he had seen no dangerous animals during the daylight hours, he had left his rifles and revolvers all within the little cabin, and now that he saw the great ape crashing through the underbrush directly toward him, and from a direction which practically cut him off from escape, he felt a vague little shiver play up and down his spine.
He knew that, armed only with an ax, his chances with this ferocious monster were small indeed—and Alice; O God, he thought, what will become of Alice?
There was yet a slight chance of reaching the cabin. He turned and ran toward it, shouting an alarm to his wife to run in and close the great door in case the ape cut off his retreat.
Lady Greystoke had been sitting a little way from the cabin, and when she heard his cry she looked up to see the ape springing with almost incredible swiftness, for so large and awkward an animal, in an effort to head off Clayton.
With a low cry she sprang toward the cabin, and, as she entered, gave a backward glance which filled her soul with terror, for the brute had intercepted her husband, who now stood at bay grasping his ax with both hands ready to swing it upon the infuriated animal when he should make his final charge.
