he seized the uplifted hand and
wrenched the sword from his grasp.

Then, without a word, Jack struck the man with the flat of his sword
upon the back of the head.

The Turk sank to the ground with a hollow groan.

It was all so momentary that the beautiful Circassian girl looked on as
one in a dream.

Hearing footsteps now, Jack ran to the doorway and peered out.

"Quick!" exclaimed Jack. "Lend me a hand, or we are lost."

She could not understand his words, but his meaning was plain enough.

They pulled the body into the sack as quickly as possible.

Then they hastily tied the cord around the neck of it.

This done, Jack extinguished the lamp.

There was no time to be lost.

He took the girl by the hand, and pulled her back into the nook where
he had been hiding, just as the two villainous eunuchs entered the
chamber.

The two eunuchs came slowly along the corridor.

Finding the place, as they thought, deserted, they simply raised the
sack from the ground, thinking the body of the young Circassian girl
was in it, and bore it to the opening.

One swing and over it went.

As it fell, a hollow groan came from the sack.

The two men stared at each other aghast, and looked over the opening.

But before they could utter a word, a stealthy form had crept up behind
them, and with a vigorous drive, hurled them both over after the sack.

A wild, despairing yell, and the waters closed over these wholesale
butchers.

CHAPTER LXXI.

LOLO'S GRATITUDE AND JACK'S DELIGHT--THE SIGNAL--UNEXPECTED TURN OF
LUCK--A FAMILIAR VOICE--WHO IS IT?--"SURELY! NEVER!"--READ AND LEARN.

"That's a good job done!" said Jack, looking after the wretches he had
pushed over.

The fair Circassian burst into tears now that the peril was over.

Falling upon her knees, she seized Jack's hands and pressed them to her
lips.

She poured out a long string of thanks in the most eloquent language.

Although the language was so far wasted upon Jack, he could not fail to
comprehend her meaning.

"There, there," said Jack, squeezing her hand in reply to her caresses,
"don't take on so, my dear girl. The danger's over now."

But was it?

They had yet to get away.

Jack was no worse off than when in his prison ten feet higher up, it is
true.

But what of Lolo?

How was she to manage?

While he was cogitating over this he heard a shrill whistle from below.

He ran to the window.

"Hist, Jack!" cried a familiar voice
