tiny ocean waves.

The unknown navigator, whatever it was, had nearly completed the circuit
of the island now, and was very near the spot where they had first heard
it.

"It must be a serpent," cried Guy. "Heaven grant that it doesn't
approach the island."

He hurriedly picked up the torch and ran with it to the shore. The
radius of light thus thrown over the water illumined a space twenty
yards ahead, and revealed a long, dark object moving in graceful
undulations over the surface. It was beyond doubt a huge serpent, and,
as though angered by the light, the monster suddenly changed its course,
and with a terrific splash headed directly for the shore. The huge head
was in plain view, and the eyes flashed back fire from the reflected
glare of the torch.

For an instant all seemed paralyzed with horror, and no one moved.

Chutney was the first to recover himself.

"We must kill him before he reaches the island," he cried, staggering
back a pace or two. "Get the guns. Quick! quick! or it will be too
late!"

The canoe was no longer on the shore. The swell caused by the approach

and the canoe continued to recede into the gloom.

At this terrible moment it was Forbes who brought a ray of hope into
their despair.

Springing forward he snatched up an armful of the native weapons,
spears, and axes, and distributed them to his companions.

"We must fight the monster with these," he cried; "and while we are
keeping him off, you, Canaris, run to the shore and keep on shouting to
Sir Arthur. He may wake and get here in time to save us yet."

"He must be in a faint," exclaimed the colonel, "or the noise would
surely have wakened him. Come on, Chutney, the serpent is halfway to the
shore. We may keep him off with these arms."

The torch was hastily placed in the sand near the water's edge, and,
grasping their weapons firmly, they prepared to check the a
