is threw it over the wall, retaining the other end in his hand.

He pulled it in a yard or two, and then the rope became suddenly taut.
The hook was secure. He took a sharp glance around him, measured with
his ear the hoarse shouts that still rose from the slave market, and
then went nimbly up the rope, hand over hand. He reached the top in
safety.

"Now fasten the stuff on," he whispered down; "put the other ropes in
the bag."

Guy obeyed instructions, and Canaris rapidly drew the string up. He then
speedily hooked a second rope to the wall and dropped it down.

"Fasten Forbes to one rope, and come up the other yourself," he called
out to Chutney.

Here a difficulty arose. Melton was, of course, unable to climb the
rope, and if a noose were slipped under his arms the wound would be torn
and lacerated by the strain.

"It's no use, Chutney," he said. "I foresaw this. You must get off
without me."

Guy was in despair. He was just on the point of bidding Canaris make his
escape alone, when a happy thought struck him.

"I have it, Melton," he cried joyfully. "Have you much power in your
arms?"

"Yes," said Melton, "but not enough to go up that rope."

"That's all right. I don't want you to go up the rope," returned Guy.
"Here, put your feet together and stand straight."

Hastily noosing the rope, he drew the knot tightly about Melton's legs
just above the knee.

"You take a good grip with your hands," he added. "There won't be much
strain on your wound and we'll have you on the top in a jiffy."

Melton obeyed instructions, and Guy pulled himself speedily to the top.

"Crouch down," said Canaris; "don't you see that watch-tower?" and he
pointed to a dim mass rising from the wall some distance off. "That is
the nearest tower," he added. "I hardly think they can see us, but it is
better to take precautions."

The other two ropes were already dangling on the outer side of the wall.
Canaris had planned everything for an emergency.

Guy took a hasty glance at the roofs and battlements spread before them
on one side, the moonlit landscape on the other, and then he whispered
down, "All right, Melton?"

"Yes, go ahead," came the faint reply.

"Quick, they are coming!" cried Canaris in sudden excitement, and as he
spoke a yell went up close at hand, and three or four dark figures
turned the corner of the nearest slave-prison.

A big Somali was in the lead, and, spying Melton, he raised his spear.

"You fiend
