"We are lost, we are lost!" he groaned. "What will become of us? Go, make another search; inspect the base of every stone; the hidden entrance must exist."
Guy shook his head.
"That cross was made twenty years ago," he said. "In that time the storms could have destroyed all trace of it unless the Englishman carved it very deep, and in that event we should have discovered it already."
"It must be found," persisted Canaris in his terror. "Hark! The firing is coming nearer. In half an hour the valley will swarm with savage foes. Go! Go! Go!"
He fairly shrieked out the last words, and threw himself in despair down amid the jungle grass.
The Greek did not exaggerate the danger. A startling confirmation of his fears was at hand.
Warned in time by a commotion in the bushes, Guy and Melton dropped flat, as a savage, spear in hand, and bleeding from a wound in the head, burst out of the jungle twenty yards distant and made full speed for a rock a few yards to the north of that by which the Englishmen lay concealed.
All unconscious of the three pairs of eyes watching his movements, he stooped, flung the tangled grass madly aside, and, rolling a loose stone from the base of the rock, revealed a dark cavity in the smooth side.
He threw a frightened glance in the direction he had come, and, dropping his spear and diving into the hole, pulled the stone back in place from within.
All this happened in less time than it takes to tell.
