There was no time for further words. The fierce tribesmen of Raab were quickly upon them, and by a concerted movement Ahmed and Dirrag whirled their horses in opposite directions, separating as they dashed away over the sands. This was intended to cause the band to divide, a part following each fugitive. But, to Dirrag’s annoyance, only two came after him, yelling and shaking their spears, indeed, but seeming not over anxious to engage him in combat, so long as he did not rejoin Ahmed.

It was upon the young heir of Mekran that most of the Raabites hurled themselves, circling around him at full gallop and watching a chance to thrust a spear into his back.

Ahmed recognized his peril. He cast his spear at one assailant, cleft another through turban and skull with his keen cimeter, and then, with a word to the gallant bay of Mehmet, he raised the horse high in the air and hurled it like a catapult at the foeman who chanced to be before him.

Even at the moment of impact the glittering blade whistled again through the air and the man of Raab sprawled with his horse in the desert sands, while Ahmed’s steed broke through the circle of his foes and bounded away to rejoin Dirrag, who was so lost in admiration of his young master’s prowess that he hardly looked to defend himself from his own assailants.

“Shall we fly?” asked Ahmed.

“It is useless,” panted Dirrag, ranging his horse beside that of his master, so that it faced the opposite direction. “They can outrun us easily, for our steeds are weary. But a few more strokes like those, my prince, and the dogs will themselves take to their heels.”

There was no indication of this at present, however. Again the enemy with fierce determination surrounded the two, and while each guarded the other’s back they sat side by side and gave stroke for stroke with calm precision.

“Hold!” cried an eager voice, sounding above the melee.

The men of Raab, as if fearful of being robbed of their prey, made a sudden furious dash. At the same time a pistol shot rang out and the leader tumbled from his saddle. The Raabites were demoralized, and fell back. They had no fire-arms.

“Forbear, I command you!” said the same imperative voice. “I am Prince Kasam.”
