"Mias! Mias!" The call came to his ears in the shrillest of tones, and was followed instantly by the crash of breaking branches. Then of a sudden something short and stout, and in the shape of a man, swung from a tree at the edge of the clearing, and went running across the open space in a half-crouching attitude, with the knuckles of its hands dragging upon the ground.

"An ape," exclaimed John Marshall in a whisper, "and a mighty big one too!"

"An orang-outang," corrected Tyler, staring at the animal. "I believe that they are very common in the island, and often grow to very large proportions. That one, for instance, is almost as big as a man. But what is happening? If he is being chased, like ourselves, why does he not rush to the other side of the clearing and get away in that direction?"

"Because he can't. Because there's natives over there, natives all round him. He's brought to bay, and he's got to fight for his life, poor beggar!"

"And will give some trouble before he is defeated. Look! he has seized a branch and means to use it as a cudgel, just as if he were a human being. But listen. There is the shout again."

Scarcely had the words left Tyler's lips than the curious call again awoke the echoes of the forest, and had barely died down when some dozen dusky figures suddenly emerged into the clearing from opposite directions and advanced upon the threatening figure, which now occupied a central point. Crash! The animal raised his cudgel at the sight of his enemies, and brought it to the ground furiously and with such force that it was a wonder that it was not broken into a hundred pieces. Then, as if the sight of the natives aroused his anger beyond everything, the ape came running to meet those who were nearest to him, his body now held fully erect. With glaring eyes and wide-open mouth, which exposed a row of terrible fangs, he ran with silent feet towards his enemies, snarling in his rage. Then, singling out one in particular, he leapt at him with unexpected suddenness, and, throwing his cudgel to the ground, gripped the unfortunate fellow in his arms.

"Look! He will kill him! The brute has caught the poor fellow's arm between his teeth, and I heard the bone crack!" cried Tyler, unconsciously raising his voice in his excitement at the scene. "Ah! the others are afraid. They are hanging back, and will desert their comrade. We must help, for we cannot lie here and see a human being killed before our eyes by such a hideous brute. Your rifle, John! Quick! out into the open!"

Almost before the boatswain had grasped his meaning, Tyler was on his feet and running between the trees at his fastest pace, and ere John Marshall could rise to follow him his leader was within a few yards of the ape. As for the natives, one more courageous than his comrades had thrust at the savage animal with a spear, and had left the weapon sticking in his back. But he might just as well have used a thorn from a neighbouring tree for all the effect it produced, for the mias did not seem to notice it, and, turning as the man dodged round him, went running towards him, still holding the unfortunate native between his teeth. And now the air was full of shouts of consternation as the natives dodged about their comrade. A few attempted to follow the example set by one of their brothers, but the gleaming fangs, the fierce snarl to which the animal gave vent as each approached, caused their courage to vanish, and instead of throwing themselves upon the ape in a body, with the firm determination to rescue their unhappy friend, they darted farther away, and stood there brandishing their weapons and calling in frightened voices to one another. Imagine their amazement when a white man suddenly burst from the trees and rushed upon the scene!

"Out of the way!" shouted Tyler, as if the natives could understand him. "Now, be ready to help me should I fail in shooting the brute. John, come up on the opposite side and let him have a bullet from your gun also."
