Then without waiting for an answer he spoke to his horse which leapt forward, followed by that of Khian and the others, and sped away.

When they had ridden thus for some minutes and the sun was up, Fire turned and pointed back towards the ford. Khian turned also and saw the bright light glancing on the spears of a great company of mounted men, some of whom were splashing through the ford, whilst others, not more than the half of a league away, were galloping towards them.

They were pursued, and the race for life began.

On they rode for hour after hour towards those hills that scarcely seemed to grow more near. Very strong were their horses and well accustomed to these sandy plains over which they swept at a long and steady gallop. Yet the way was far, also for days already they had been ridden across the desert, and that morning they had swum a wide stretch of rapid water, whereas those of the Shepherd troops were fresh from the stable. Still throughout the burning heat of the day those horses held their own, and when it drew towards evening and at length that pass in the mountains was at hand, still they held their own. Yes, parched with thirst, panting, thin-bellied, still they held their own. Long ago most of the Shepherds had fallen out and vanished, so that when at length the pass was reached, not a score of them remained, men who had remounted upon led horses when those they rode were foundered. But now these were hard upon their prey; scarce a bowshot behind indeed.

Khian and his company stumbled up the pass, for the horses, both of the pursued and the pursuers, had ceased to gallop and at the best could but amble forward. Yet step by step the pursuers gained upon the pursued. The sides of that pass were very steep and the pathway was very narrow; one horse filled it all and therefore they must ride one following the other.

Suddenly at a turn in the road, when the first of the Shepherds was scarcely more than fifty paces away, that Arab or Babylonian, or Brother of the Dawn, whichever he might be, who was pleased to give himself the name of Fire, turned and shouted an order. Thereon the last of those four brethren, he who was called Water, dismounted and with drawn sword took his stand at the turn of the narrow path, while his weary horse followed its fellows, as by certain words and signs he bade it do. Presently those of the party of Khian heard the sound of clashing arms behind them, followed by silence. Then a while later the pursuers appeared again, only whereas there had seemed to be fourteen of them now but eleven could be counted.

Once more they gained, once more they drew near, whereon he who was named Fire shouted a second order, and that brother of his called Air dismounted in another narrow place, leaving a second horse without a rider to follow in the train. Again there was a sound of clashing arms, and, when the pursuers reappeared, there were but nine of them. As before, they gained, and as before, at a narrow place the word of command rang out and the third of the brethren, he who was called Earth, dismounted, waiting. Followed the clash of arms and the shoutings, and when the pursuers reappeared there were but six of them. They gained, they came very near, whereon at a chosen place the first of the brethren, he who was named Fire, halted and leapt from his horse, which he drove forward as the others had done.

“Ride on, Lord,” he cried. “Should the god we worship give me strength and skill, for you there is yet a hope of safety. Ride on and forget not the message I gave you by the water.”

“Nay,” answered Khian wearily, for his head swam and scarce he knew what passed about him. “Nay, here I stay to die with you. Let Temu, who understands nothing, deliver your message.”

“Begone, Lord!” cried Fire. “Would you put me to shame and cause me to fail in my trust, making my name a hissing and a reproach? Begone or I fall upon my sword before your eyes.”
