hers,
as they hurried from stone to stone, scrutinizing every side and angle,
failed to discover the faintest trace of anything resembling a cross.

Canaris wrung his hands in dismay when they came together after the
fruitless search.

"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.

"Saved!" burst thankfully from Guy's lips as he sprang to his feet.

"Saved!" echoed Melton and Canaris.

Snatching up their baggage, they dashed across the narrow space that
divided the two great boulders. Guy tore the rock from the entrance,
and, as the imprisoned savage within uttered a hoarse cry, he pointed
his rifle at the opening.

"Go ahead," called out Melton; "he's unarmed; he can't harm you."

Guy hesitated for an instant, and then crawled into the forbidding
cavern on hands and knees.

A distant sound of scuffling and rattling of stones told that the savage
was retreating into the bowels of the earth.

Melton handed in the rifles and the baggage, and crawled in after them.
Canaris was the last to enter, and with Melton's aid the
