stranger before he could reach it. Whipping out a pistol as a precaution—for he knew not whether the Arab was friend or foe—he stood back. The Arab darted round the corner at racing speed, saw the pistol pointed at him, and swerving slightly grabbed at Burnet's wrist. The sudden wrench jerked the pistol out of his hands and at the same time caused both men to lose their balance. Burnet, the first to recover himself, freed his arm with a dexterous twist, and the two men closed, stumbling and swaying over the broken surface of the tell.

THE STRUGGLE ON THE TELL

As soon, however, as Burnet got a firm hold the issue was not long in doubt. The Arab wriggled like an eel, but he was no match for the Englishman either in physical strength or in athletic skill. Moreover he was already winded by his impetuous rush over the heavy ground. Burnet freed himself without much difficulty from his opponent's grip: then, getting his hand behind the Arab's neck in the position known to the wrestler as the "half-nelson," he forced him downwards and finally threw him helpless into a pocket of sand. In a few seconds he had secured the man's weapons—a clumsy pistol and a crooked dagger called shabriyeh—and regained his own pistol. Then he stood above the Arab, who now lay on his back, staring up at the supposed fellow-Arab who had thrown him so easily and in a manner so unfamiliar.

The stranger was no older than Burnet himself. He was an Arab of the best type, with handsome features and intelligent and fearless eyes.

"Rise, I pray you, brother," said Burnet in Arabic. "We have somewhat to say one to the other."

The Arab got up quickly. Puzzled as he had been by the wrestling trick, he was still more puzzled by the friendly manner of the man who had vanquished him, and especially by the slight smile that accompanied his words. He fixed his keen eyes on Burnet's face, but said nothing.

"I am alone here, as you see," Burnet went on, "and in these times, when it is hard to know friends from foes, a man must needs take care. We are strangers, yet it may be that we are also friends."

The Arab assented merely with a word, but did not relax his attitude of watchfulness. This man who spoke to him used good Arabic, but was more direct and less given to expletives than the average Arab.

"You are my captive," Burnet continued. "Tell me who you are, whence you come, and why you ran hither in such headlong haste."

"My lips are dry; give me drink," said the Arab.

"By the grace of Allah I have fresh water—not like the foul water of the swamp," said Burnet, unscrewing the stopper of his water-bottle. "Drink, brother."

The young man took a deep draught, returned the bottle with a word of thanks, and said:

"My tongue will speak true things, and Allah judge between us."

Burnet threw a keen glance around the horizon, then sat down on a broken block of stone, inviting the Arab to sit opposite him. And then the young man began his story.

His name was Rejeb, and he was the chief of a clan of the Anazeh whose territory lay on the far side of the Euphrates. His father, now some years dead, had been a lifelong rebel against the Turkish rule, and in his last year had suffered a disastrous defeat through the defection and treachery of another chief who had been his ally. In this final battle he had lost his life; his people had escaped extermination only by fleeing into the desert. Since the outbreak of the Great War they had gradually reoccupied their old districts, the Turks having enough to do without taking measures to suppress so unimportant an enemy. It was otherwise, however, with the treacherous tribe which had been his father's ruin. For some time its chief, Halil, had made no sign: his fighting strength was greatly reduced through the fact that many of his men were with the Turks. But after the British failure to relieve Kut he had collected a considerable force, and taking advantage of Rejeb's absence at Kerbela he had first cut off the young man's tribe and then attacked it. The tribe, after a stout resistance, had made good its retreat across the Euphrates, to a fastness in the swamps. Rejeb, on his way back from Kerbela, had been met by a messenger with news of the reverse, and, changing his route in order to rejoin his people, had been chased by a party of Halil's horsemen. In eluding them he had lost touch with the messenger who had hitherto accompanied him; his horse had foundered, and the only course then open to him was to swim the Euphrates on a skin. This he had done, and thought himself safe, when the reappearance of his pursuers revived his anxieties. Fortunately their horses were useless in the swamps, and on foot he had reasonable hope of escaping them. An hour or so, however, before his arrival at the tell, he had only just succeeded in giving their main party the slip. The direction of his flight had been seen by three or four of their number who had separated from the rest, and he did not doubt that these three or four, if not the whole body, had tracked him and before long would reach the tell.

Rejeb's story was told rapidly, and with an air of sincerity that would have disarmed suspicion even in one far more sceptical by nature than Roger Burnet. The news that men of a hostile tribe in Turkish pay were hastening to this spot was very disturbing. Burnet knew that he was in fully as much danger from his captive's pursuers as the captive himself. His disguise might pass muster; the story he had invented to account for the presence of a solitary boatman so far from the river, if he were challenged, was sufficiently plausible; but if he was found in the company of the young chief whom Halil's men were hounding down he would certainly be seized and carried to Halil for examination at least. He had very little time in which to secure himself.

The obvious course was to release Rejeb, who would no doubt continue in the direction he had been going, and as soon as he was out of sight, to take refuge in the subterranean room until the chase was past. But the young chief was jaded, worn out by his hurried flight and the subsequent struggle on the tell. It was almost certain that he would be run down. Burnet had taken an instinctive liking to him; he could not give him up to his enemies, who were at the same time enemies of the British. After a few moments' reflection he turned suddenly to the Arab and said:

"If I save you from the hands of Halil, will you swear by the beard of the Prophet not to play me false?"

Rejeb was apparently staggered by this strange offer from a man with whom, a few minutes before, he had been locked in fierce struggle—a man, moreover, who had given no account of himself and about whom there was something mysterious. He flashed a keen questioning glance at Burnet, as if fearful of a trap.

"You are no boatman?" he said slowly.

"And if I am not? What is that to you if I am a friend?"

The Arab hesitated for a brief moment. Then perhaps it occurred to him that his situation could scarcely be worse than it was; perhaps he was mutually attracted to this young man of his own age. At any rate, after the slightest pause, he said, raising his hand:

"By the beard of the Prophet I swear it."

During this conversation the two men had remained behind the wall, Burnet every now and then peering through a gap in the masonry in the direction from which the Arab had come. He now suggested that Rejeb should go to the corner and keep watch for the pursuers. Having left his field glasses with the rest of his equipment in the underground room, he was less able than the keener-sighted Arab to view the distant country.

Rejeb went to the corner and flattened himself against the wall with the instinct for cover natural to a dweller in the wilds. In a few
