y all lay on his left,
while the alarming noise seemed to come from the right.

Guy was a brave man, but in his nervous condition, resulting from the
recent dream, this new alarm was too much, and he felt a cold chill run
down his spine.

Giving Forbes, who was next him, a gentle shake, he drew himself to his
feet, and taking a match from his pocket, rubbed it with a trembling
hand across the front of his trousers.

It struck fire instantly, and as the sudden flare lit up the whole
extent of the island the match dropped from Guy's nerveless fingers and
he started back with a cry of horror that echoed horribly through the
gloomy recesses of the cavern.

CHAPTER XXIII.

A WONDERFUL ESCAPE.

Guy had presence of mind enough to strike a second match and ignite the
torch, which was fortunately within reach of his hand, and as his
companions, roused from their sleep by his sharp cry of alarm, sprang

Unluckily Forbes was bent on resistance. He seized his rifle, made sure
that it was ready for use, and started forward just as Guy hurried to
his assistance.

"Come away, Melton," he cried; "it will only make things worse if you
wound it."

"But I don't intend to wound it," replied Melton. "I'm going to put a
ball through that ugly head. Stand back, Chutney; stand back."

As he spoke he advanced recklessly until the muzzle of his rifle was
within two feet of the serpent's head, and, taking a quick aim, pulled
the trigger.

The stunning report shook the cavern; then, as Forbes turned to flee,
the enraged monster, with blood streaming from a hole in his neck, threw
his slimy coils forward i
