view upon the top.  Then came a shrill cry, a horrible strenuous scream of surprise and terror, and an instant later the party streamed into sight again, dragging the women in their midst.  Sadie, with her young, active limbs, kept up with them, as they sprang down the slope, encouraging her aunt all the while over her shoulder.  The older lady, struggling amid the rushing white figures, looked with her thin limbs and open mouth like a chicken being dragged from a coop.

The chief’s dark eyes glanced indifferently at Miss Adams, but gazed with a smouldering fire at the younger woman.  Then he gave an abrupt order, and the prisoners were hurried in a miserable, hopeless drove to the cluster of kneeling camels.  Their pockets had already been ransacked, and the contents thrown into one of the camel-food bags, the neck of which was tied up by Ali Wad Ibrahim’s own hands.

“I say, Cochrane,” whispered Belmont, looking with smouldering eyes at the wretched Mansoor, “I’ve got a little hip revolver which they have not discovered.  Shall I shoot that cursed dragoman for giving away the women?”

The Colonel shook his head.

“You had better keep it,” said he, with a sombre face.  “The women may find some other use for it before all is over.”

CHAPTER V.

The camels, some brown and some white, were kneeling in a long line, their champing jaws moving rhythmically from side to side, and their gracefully poised heads turning to right and left in a mincing, self-conscious fashion.  Most of them were beautiful creatures, true Arabian trotters, with the slim limbs and finely turned necks which mark the breed; but among them were a few of the slower, heavier beasts, with ungroomed skins, disfigured by the black scars of old firings.  These were loaded with the doora and the waterskins of the raiders, but a few minutes sufficed to redistribute their loads and to make place for the prisoners.  None of these had been bound with the exception of Mr. Stuart—­for the Arabs, understanding that he was a clergyman, and accustomed to associate religion with violence, had looked upon his fierce outburst as quite natural, and regarded him now as the most dangerous and enterprising of their captives.  His hands were therefore tied together with a plaited camel-halter, but the others, including the dragoman and the two wounded blacks, were allowed to mount without any precaution against their escape, save that which was afforded by the slowness of their beasts.  Then, with a shouting of men and a roaring of camels, the creatures were jolted on to their legs, and the long, straggling procession set off with its back to the homely river, and its face to the shimmering, violet haze, which hung round the huge sweep of beautiful, terrible desert, striped tiger-fashion with black rock and with golden sand.
