Now orders followed in quick succession. We could hear them rigging the fish tackle and catching the hooks on the flukes of the anchors. Blocks rattled, braces creaked, the yards swung from side to side according to the word of command. The sails filled with the light breeze, and coming slowly about, the Adventure gathered steerage-way and went down the river as if she were some gigantic water bird lazily swimming between the mangroves. We watched her go and knew that we seven were now irrevocably left to fend for ourselves.

When Gleazen whispered to us to give way, we bent to the oars with a will. For better or for worse, we had embarked on the final stage of our great quest.

The lights in the clearing fell astern. The tall trees seemed to close in above us. Alone in the wilderness, we turned the bow of our boat toward the heart of Africa.

That we had set forth in complete secrecy on our voyage up river we were absolutely confident. What eyes were keen enough to tell at a distance that the brig had left a boat behind her when she sailed?

Gleazen now laughed derisively at O'Hara. "You'd have had us sail away, would you? And wait a month? Or a year, maybe, or maybe two. Ha, ha!"

"Don't you laugh at me, Neil," O'Hara replied. "We're not yet out o' the woods."

At the man's solemn manner Gleazen laughed again, louder than before.

As if to reprove his rashness, as if to bear out every word O'Hara had said, at that very moment the uncanny yell we had heard before rose the second time, far off in the swamp. Three times we heard the yell, then we heard the voice, faint and far away, "White man, I come 'peak. White man boat him sink. White man him go Dead Land."

Three times more the wordless wailing yell drifted to us out of the darkness; then we heard a great multitude of men wildly and savagely laughing.
