"Then the sooner we send back to our fellows the better," cried Daglish. "There's open ground before us, and the two troops could operate so as to drive in a blow at those fellows."

Pulling his notebook from his pocket he wrote a few hurried lines, and, having folded the "chit" up, he addressed it to his commanding officer.

"Take it back, Harmer," he ordered. "You can tell them that Keith and I will go on a little and make out those fellows a trifle more clearly."

A minute later the third of the officers was in his saddle and galloping back towards their comrades, whom they had left some distance away, halting at the bottom of this long sloping eminence. Then Geoff and Daglish climbed into their saddles and urged their horses forward, Geoff looking critically at the mount upon which his companion was riding.

"Better go easily, Daglish," he told him, "for that little horse of yours doesn't look as though he was fast, and I can tell you many of those Arab horsemen are superbly mounted. We can go on a little way, of course, and then, if it's the same to you, I'll push on still closer, for there's not a horse yonder that can even look at Sultan."

It was perhaps five minutes later when the two drew rein, for even though Daglish was full of energy and enthusiasm, and indeed was a brilliant cavalry officer, yet he was not devoid entirely of discretion. Though he was itching with eagerness to get to grips with the enemy, and to come to close quarters, he could not fail to realize the weight of the warning which Geoff had given him; nor, having seen that little exhibition which Sultan and his master had given them so close to the place of disembarkation, could he doubt that there were few who could come up to the magnificent Arab Geoff was riding.

"All right!" he told Geoff, a little reluctantly, as he pulled in his horse. "I'll stay here and keep my glasses on them, while you go on a little. Now, don't be reckless; for recollect you are of some value to the expedition, seeing that you speak the lingo."

Shaking his reins, Geoff set Sultan in motion, while Daglish watched him for a while as he cantered towards the enemy; then he threw up his glasses, and, fixing them upon the Arab horsemen, watched their waving lines, the chiefs who sat their horses in front of them, and one man in particular, who cantered slowly along their front—his white cloak thrown back, his dusky arm bare, the weapons he was carrying distinctly visible. It was fascinating to watch that gallant horseman, for a fine sight this Arab made. He pulled in his horse after a while in front of his men, and from the movements of his head it seemed as if he must be haranguing them; then of a sudden he stood in his stirrups and flung the pistol he was carrying high in the air, while an instant later there rolled musically across the desert the sound of shouting—a sound unfamiliar to Daglish's ears.

"Allah!" he heard; "Allah!" That weird, majestic, inspiring call of the Arab. It made the young officer almost twitch; made him admire those horsemen even more, and made him start violently when a second later he saw through his glasses that self-same chief swing his horse round, shield his eyes with one hand as he stared in Geoff's direction, and then set his horse going at a mad pace which promised to bring him rapidly up to him. Almost at the same instant the Turkish infantry—a mere handful of men—who had been hidden behind the horsemen almost completely, debouched into the open at their left, and at once the sharp rattle of rifle-fire came echoing across the desert. As for Geoff, he heard the sounds and saw that horseman. Little puffs of sand began to rise up all round him, while now and again something buzzed past his head, humming its way on into the distance.

"Near enough," he told himself coolly, pulling Sultan up, while he felt for his glasses; then, dropping his reins, he focused the enemy again, and took very careful stock of them. "Doubt if there are three hundred horsemen there," he thought; "two hundred is more like their number, and a mere handful of Turkish infantry I should say, though having infantry with them points to the fact that they are a garrison retiring up river. And what's that chief mean by riding out like that in front of all his people? Anyway, he's now between the infantry and me, and that will put a stop to those bullets."
