Finally, as though from sheer joy of what he had accomplished, he raced from the cabin, and out across the clearing. Ellen and Bentley smiled at each other. Moments passed. Still came to their ears the mourning wails of the great apes. * * * * * Then suddenly there broke a sound so utterly appalling that the two were frozen with terror for a moment. First it was the laughter of Caleb Barter. Then, mingled with the laughter, the bellowing, frightful and paralyzing, of man apes challenging a hated enemy. The drumming of ape fists on huge barrel chests. Then the laughter of Barter, dying away, ironic, terrible, into silence. Immediately afterward, high-pitched, mighty as the jungle itself, the concerted cries of half a dozen apes, as if bellowing their joy of the kill. "They--they--" began Ellen in a choked voice. "The apes must have got Professor Barter!" Silently Bentley nodded, and pointed. Coiled on a nail near the door was Barter's whip. In his excitement he had gone into the jungle without it for the first--and last--time. "There is one thing to do," whispered Ellen, "before we prepare to get you fully well. I shall care for you, and we shall both try to forget. And then we shall return to our own people." "And the one thing?" asked Bentley. The strained silence was suddenly broken by the bellowing of the great apes, which now charged into the cabin. Bentley and Ellen cringed back from the murderous brutes to no avail. There was no denying them. Their slavering jaws, drooled below flaring nostrils, their eyes emitted sparks of animal fury. Bentley leaped to the girl and interposed his body between hers and the vanguard of the apes, who now were surging into the room through the open door, and spreading apart within like water released from a dam. The apes were bent on murder, there could be no doubt. A very monster towered over Bentley. His jaws were wide, his little red eyes fixed on the white man's neck. His great arms were coming forward to gather in both Ellen and Bentley--whom he could crush as easily as he crushed the grubs which were his food. Bentley was helpless and knew it. This was the end for Ellen and himself. He must meet it unafraid. He tensed, awaiting the descent of bestial destruction. His eyes met the murderous gleam in the eyes of the ape leader unflinchingly. And then the miracle happened. The brute became suddenly and inexplicably hesitant. His bellow died away to a gurgling murmur in which there seemed somehow a hint of apology. The fire went out of his eyes. His jaws closed with a snap. His great arms, already about Bentley, slid harmlessly over Bentley's shoulders; dropped to his shaggy side.
