Seeing the gigantic monster swooping towards them, the Arabs--men, women, and children--took to flight. Even the spearman who was in charge of the captives took to his heels and ran for the scanty shelter of the palm trees. "Stand by to run for it!" exclaimed Mr. Reeves. "But don't move till I give the word." The correspondent still kept his eyes fixed upon the rapidly approaching monoplane. One of the men in it did exactly what Reeves expected he would do--he leaned sideways and dropped a small bomb. Five seconds later the missile struck the ground, and burst with a deafening report, throwing showers of sand in all directions. Two of the rearmost Arabs fell, and several of the sheep and cattle were literally blown to atoms; but, although small pieces of iron and plenty of sand swept over the prostrate captives, Reeves and the two lads escaped unscathed. "Now, run for it!" shouted the correspondent, for the monoplane was skimming over the palm trees, its crew evidently thinking that one bomb was enough. Hampered though they were by their arms being tied by the camel rope, the fugitives made good progress. Could they but gain the shelter of that part of the oasis lying to the north of the camp, chances would be in their favour, since the Arabs had taken refuge on the southernmost side. But just as they were on the verge of the thick scrub Hugh stumbled and, unable to break his fall, crashed heavily upon the ground. This brought the others up, and as Mr. Reeves stooped to help the lad, as well as the hampered condition of his arms would allow, a loud shout told them that their flight had been discovered. Escape was now out of the question. Surrounded by twenty Arabs, whose rage had been increased by the slaughter of much of their stock, and who imagined that that was part of an attempt by the Italians to free the three Kafirs, they were dragged back to the encampment, where they were beaten and kicked till the two lads, who barely knew what bodily pain was, were almost dead. As for Mr. Reeves, he took his punishment gamely, knowing that any resistance or sign of fear would make their captors take a keener zest in their work. The attack upon the encampment made things worse for the three prisoners, for the Arabs, finding that they were still within range of their foes, immediately struck their tents, and before sunset the diminished followers of the Sheikh Wadherim were on their way southward to the distant oasis of Wadi Tlat.
