those who were known as Air and Water.
The horses went in bravely enough, and soon Khian saw that Fire's was swimming while its rider had slipped from its back and floated alongside, holding fast to the mane or saddle. Presently Khian's horse also lost foothold and as Fire had done, so did Khian. The swim was long and rough, for the swiftly running water, chilled by the night air, drove them downstream and sometimes broke over their heads. Yet those trained horses held on bravely, smelling the pastures where they were born beyond the desert, and being, as Fire had said that they would be, eager to reach them.
At last they touched the farther shore and Khian, still clinging to the horse, was dragged through the rushes to firm ground. As he came there he heard a shout of "Help!" and looking round, saw Temu's horse struggling up the bank, but unaccompanied by Temu, who indeed, having let go, was floundering in the deep water and being swept down by the current at a distance from the shore. All this the strengthening light showed to them, whereon without a word two of the brethren plunged into the stream and swam to Temu whose shouts grew ever louder. They reached him and with difficulty between them dragged him to the shore, much frightened, but unharmed and still calling to gods and men to save him.
Then one of those strange, fierce brethren drew a knife, saying:
"Will you be silent? Or shall I make you so, who are bringing us all to death?"
"Your pardon," said Temu when he understood, "but my mother always taught me that he who drowns in silence, drowns the most quickly; also I ask you to note that my prayers have saved me."
Muttering words that Temu would have thought evil, Fire helped to thrust him on to his horse and signed to the others to mount theirs.
"Hearken, Lord Rasa," he said, as they pushed their way through the thorn bushes that grew on the bank of the water, "ill-fortune is our companion. The shouts of that mad priest will almost certainly have been heard. Would that he had choked before his throat shaped them. Moreover, he has delayed us, so that the morning wind blows away the mist which I hoped would shroud us for a while. Now there is but one thing to be done--ride straight for the gap in the hills and through the pass. Our horses are better than any the Shepherds have, though theirs will be more fresh, and we, or some of us, may outpace them. At the least, remember this, Lord Rasa, if so in truth you are named, we four brethren will do all that men can do to save you, and we pray you, if we meet no more, so to report to a certain Lady whom we serve, and to the Prophet and Council of the Dawn, that our memory may be honoured among men."
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."
Then as Khian still stayed swaying in the saddle, that most gallant man called some secret word to the horse he rode and the beast, understanding, stumbled onwards at a trot, nor could Khian stay it.
Once more there came the clash of arms and the sound of shoutings, and presently Khian, looking back, saw that of the pursuers but three remained. He urged his horse but it could do no more. Almost at the crest of the pass it whinnied and stood still.
The three struggled on grimly, for they were afoot, having left their spent beasts behind them. They were strong, soldier-like men, black with dust and sweat, and one of them had been wounded for blood ran down his face and robe, he who seemed to be an officer.
"We are commanded to take you dead or living, Prince Khian, for so you are. Shall we slay you or will you yield?" asked this man hoarsely.
Now when he heard these words Khian's spirit came back to him, and with it some of his lost strength.
"Neither," he answered in a low tone.
Then, changing his sword from the right hand to the left, from his belt he snatched his short javelin and hurled it with all his strength. The officer saw it coming and shrank aside, but in that narrow place it caught the man who stood behind him, piercing him through from breast to back, so that he fell down and died. Then the officer sprang at him and they fought with swords, a well-matched pair, though both were very weary, while the third man who could not come at Khian strove to drag the javelin from the breast of him who had fallen. The officer smote, somewhat wildly, perhaps the blood from his wound had run into his eyes. Khian parried, then bending himself, thrust forward and upward with all his strength, a trick of swordsmanship that he had learned in the Syrian wars. The bronze blade caught the officer in the throat just beneath the chin, and piercing to the neck bone, severed it, so that down he went like a stunned ox, in his fall twisting the sword from Khian's sweating hand. Then it was that the third man, having recovered the javelin, cast it at him, though with no good aim, for it struck him, not in the body, but above the left knee, piercing the leg from front to back.
