The great head was thrust forward, with its low black forehead and blacker muzzle; then they saw the whites of the eyelids as the fierce creature swiftly raised and lowered its brows; then the gleam of the great tusks as the mouth opened to emit a tremendous roar. The branches cracked under its grip as it shook them again before disappearing. Mr. Hume unslung his rifle and planted himself firmly, for, from the sound, it seemed as if the great ape were coming straight for them. But the noise of its progress ceased, and, after a long wait, the march was resumed. They kept a very keen outlook, and at times stopped to listen, but apparently the gorilla had vanished. Yet many were the startled looks whenever the least sound broke on their ears, for the face of the great ape, suddenly thrust into view, was a terrifying object.

"Halloa!" said Venning, pulling up, "the path seems to end here. See, the branch is broken off; and there is no swing-bridge. Yet the track did go straight on, for you can see the old marks across there."

"Wow!" said Muata, as his dark eyes swiftly took in the details.

"If I climbed up that branch, I think I could get into the other tree, and you could then use the rope."

"What is it now?" asked Mr. Hume.

"They have cut the track," said the chief; "and it is as I thought, they have gone down from this tree to the ground, maybe to climb up further on."

"Why?"

"Maybe a man has fallen to the ground here—who can say; or the stinging ants have made a home. That tree beyond is taboo to the little people, and we also will go down here."

"What's the good?" said Venning, beginning to climb up.

"No, no," said Mr. Hume. "We must leave this to the chief;" and he turned to descend.
