ave impaled himself on the savage's outpointed spear.

It was too late to use the revolver which he still carried in his hand,
but quick as a flash he hurled it with all his might, and with such
correct aim that it landed plump on the fellow's head with an ugly
crack.

The Somali howled with agony, letting the spear drop from his nerveless
hands, and just as it clattered to the ground Canaris was upon him with
a rush, and down they went together, the Somali undermost.

Canaris was up in a trice, and Guy and Melton, bounding on behind,
trampled the half unconscious savage under their feet.

"Go on," said Guy fiercely. "We will outwit them yet. Brace up, Melton;
we'll soon be out of this hole."

Forbes gritted his teeth to suppress a cry of pain.

"I can't keep up much longer," he said. "I'll faint from loss of blood."

The place they had just entered was the great trading locality and slave
market of the town. At this time of year it was deserted, but the empty
stalls and booths stood about in endless confusion.

The wisdom of the route chosen by Canaris was now apparent, for this
labyrinth of paths, which wove an intricate network through the stalls,
offered just the opportunity they wanted; and, following the Greek's
guidance, they twisted in and out in a tortuous line that gradually

the opposite side of the market in safety, and, plunging in among the
mass of empty prisons, ran on, panting and breathless.

The Greek's white burnous fluttered on ahead, turning angle after angle,
diving into dark alleys and shooting across open spaces. At last he
stopped and, too exhausted to speak, waved his hand in triumph at the
frowning wall of the town that towered directly over their heads for
twenty feet.

Close by the wall was a circular stone tower, partly in ruins, and into
this Canaris dived eagerly. It was an anxious moment to the two who
waited on the outside, but at last the Greek reappeared in triumph with
his hands full. The Jewish merchant had kept his promise.

He paused a second or two to listen to the outcry in the town.

"They are coming nearer," he said. "Keep cool and d
