the Sheik of the Pyramids, also those, whoever they might be, that had sent these Arab horsemen to their succour, if they were Arabs, which as yet he did not know. But he only answered:
"I trust that you are right, Brother, and that all will be well. Yet remember that if we were seen as we left the pyramid and that if we escape a second time heads will pay the price of it. Therefore surely we shall be followed, even to the end of the world."
"Faith, Brother! Have faith!" exclaimed Temu as he shifted his seat to find one that was softer.
Just then Khian saw him who seemed to be the leader of the four Arabs, a tall and noble-looking man, standing at a little distance as though he desired speech with him, and alone.
He rose to go to him, and as he came the Arab bowed humbly in salutation and made a certain sign which Khian knew.
"I see that you are of the Brotherhood. Tell me your name and those of your companions; also who sent you in so fortunate an hour to help us, and whither we go."
"Lord, we are four brethren. I, the eldest, am named /Fire/. He who stands there is named /Earth/: the next to him is named /Air/, and the fourth and last is named /Water/. We have no other names, or if there are any we forgot them when we were sworn Brethren of the Dawn, and especially when we were despatched upon a certain duty."
Now Khian understood that for their own reasons, or because of some command laid upon them, these men desired to remain unknown, as was common among the Brethren when they were sent upon any secret service.
"Is it so, Fire?" he said, smiling. "But what answer to my other questions?"
"Lord, we were commanded to take six good horses and, disguised as you see us, to go to the Great Pyramids and there bargain with soldiers, if we found any, over such wares as Arabs have to sell. Also we must make ourselves known to the Sheik of the Pyramids, if we could, and give aid to a scribe, Rasa--perchance you are he, Lord--and to his companion, a priest whose name was not mentioned, but whom we have heard you call Temu, if he be the same."
"And then, Fire?"
"Then, Lord, we were to say to the Scribe Rasa that a certain Lady--we know not and, lest we should be captured and questioned, do not seek to know, what lady--with all her following, has passed safely out of Egypt and that the Scribe Rasa and his companion must follow by the road she took. Lastly, we were sworn to bring both of you safely to Babylon, or die at the task, which, Lord, we purpose to do. Now, Lord, we must ride again. These horses are of the most swift and purest desert blood but we have far to go before we can find others, and certainly we shall be pursued. Moreover," he added, eyeing Temu doubtfully, "I think that yonder priest is more wont to travel on two feet than on four, and until he learns the trick of horsemanship, we must go with care lest he should fall or faint. Lastly, both of you are weak who have, I think, lain for many days in an evil prison."
"True words, Fire," said Khian as he sought his horse.
All that day they rode forward, resting while the sun was high and sleeping at night among some rocks where once more they found food and water for man and beast, and at length Temu, who was brave and active, began to lose his soreness and to win something of that trick of horsemanship of which he who was called Fire had spoken. Also in the strong and wine-like desert air their tomb-bred weakness and langour passed away from both of them, and they grew strong again, as young men do.
One night they slept upon a mound by water where once had stood some village, both men and horses being well hidden by a grove of thorn and other trees that flourished in the rich soil of the mound. As the sun sank behind them, he who was called Fire came to Khian and bade him look through the trees towards the east. He did so and to their right saw that at a distance of perhaps a league, a broad canal or natural sheet of water that may have been the head of a lake was crossed by a ford, beyond which stood an old and crumbling fort built of sun-dried bricks, while in front of them there was no ford and the water seemed to be wide and deep. Beyond this water was a great flat plain that stretched away and away, till very far off upon the horizon it seemed to end in a line of stony hills.
"Listen now, Lord," said Fire. "That water is the boundary of Egypt. That plain is Arabia, and among those hills is the first desert outpost of the army of the King of Babylon, to reach which will be to win to safety. But I tell you, Lord, that we are in great danger. I am certain that yonder old fort is held by the horsemen of King Apepi, for I have seen their tracks in the sand, a number of them, fifty men perhaps, and that they watch for us, believing that if we would leave Egypt, we must do so by this ford."
"Why?" asked Khian. "Can we not find another?"
"There is no other, Lord, since below, this water grows into a gulf, and above it is deep for many miles, so that to pass round it we must ride through a peopled country guarded by the border garrisons."
"Then it would seem that we are trapped or must fly back into Egypt."
"Where we should be trapped indeed, Lord, for by now the whole land is searching for us."
"What then, Fire? Know that I would sooner look upon the face of Death than upon that of Apepi."
"I have guessed as much. Listen, Lord. All is not lost. These fleet horses of ours were bred in Arabia, yonder among the mountains, and they scent their home and the troops of mares that wander there. The water in front of us will be unwatched because it is so wide and deep and the current runs so swiftly. Yet I think that the horses will not fear to face it, and once across, with good fortune we may ride far before we are seen and perhaps even reach the pass of the hills in safety. It is a narrow pass, Lord, where one man can hold back a number for a long while, so that some of us, at least, should win though to the heart of the hills and find shelter among the scouts of Babylon," he added slowly and with meaning.
Then speaking very rapidly, he explained to Khian all the details of the plan which he and his brethren had prepared. He told him, and Temu, who had joined them, how they must move down to the water edge before the dawn and at the first light ride the horses into it, and as soon as it grew deep, slip from the saddles and swim with them, clinging to their manes.
Here Temu explained that he could not swim, whereon Fire answered that he must hang to his horse as best he might, or drown. He went on to say that those of them who lived to reach the farther shore must mount at once and ride for a certain bay in the hills where the pass began, which bay would become visible to them before noon. The pass they must climb, on foot if the horses had failed them, and descend its farther side to the entrenched camp of the Babylonian company who had orders to succour all fugitives from Egypt.
Having set out these and other matters, he bade them drink and sleep while they could, for none knew what might be their resting place on the morrow.
Khian obeyed, knowing that he must harbour his strength. The last thing he saw ere his eyes closed was the four strange brethren grooming the horses and with set faces talking to each other in whispers as they worked, also, nearer to him, Temu on his knees, lost in earnest prayer. For with all his faith Temu remembered that this water was said to be broad and deep, and that--he could not swim.
It seemed that but a few minutes had gone by when one of the brethren woke Khian, saying that it was time to be stirring. They rose by the starlight, set the bridles and the saddles on the horses which had been fed already, mounted them, and followed the brethren down towards the water. They reached it in safety just at the first glimmer of dawn, by the light of which Khian saw that it was indeed wide--scarce could the strongest bowman have shot an arrow from one bank to the other. Also some tide or current seemed to run very strongly through it towards the ford below, which was to this water as is the neck of a wine-skin to the bottle.
"Would it not be safer to risk the ford?" he asked of Fire doubtfully.
"Nay, Lord, for there we should certainly be seen and perhaps killed upon the bank, whereas here, where no man crosses, they may not note us from so far away. Follow me now, before the light strengthens."
Then, having patted his horse and whispered into its ear in the Arab fashion, he rode into the flood. After him came Khian, followed by another of the brethren and by Temu. Last of all rode the remaining two brethren,
