Two of the Arabs mounted the old camels and rode slowly away to Omdurman. Abou Fatma and the other remained with the fugitives. They mounted and trotted northeastwards. No more than a quarter of an hour had elapsed since they had first halted at Abou Fatma's word.
All that night they rode through halfa grass and mimosa trees and went but slowly, but they came about sunrise on to flat bare ground broken with small hillocks.
"Are the Effendi tired?" asked Abou Fatma. "Will they stop and eat? There is food upon the saddle of each camel."
"No; we can eat as we go."
Dates and bread and a draught of water from a zamsheyeh made up their meal, and they ate it as they sat their camels. These, indeed, now that they were free of the long desert grass, trotted at their quickest pace. And at sunset that evening they stopped and rested for an hour. All through that night they rode and the next day, straining their own endurance and that of the beasts they were mounted on, now ascending on to high and rocky ground, now traversing a valley, and now trotting fast across plains of honey-coloured sand. Yet to each man the pace seemed always as slow as a funeral. A mountain would lift itself above the rim of the horizon at sunrise, and for the whole livelong day it stood before their eyes, and was never a foot higher or an inch nearer. At times, some men tilling a scanty patch of sorghum would send the fugitives' hearts leaping in their throats, and they must make a wide detour; or again a caravan would be sighted in the far distance by the keen eyes of Abou Fatma, and they made their camels kneel and lay crouched behind a rock, with their loaded rifles in their hands. Ten miles from Abu Klea a relay of fresh camels awaited them, and upon these they travelled, keeping a day's march westward of the Nile. Thence they passed through the desert country of the Ababdeh, and came in sight of a broad grey tract stretching across their path.
"The road from Berber to Merowi," said Abou Fatma. "North of it we turn east to the river. We cross that road to-night; and if God wills, to-morrow evening we shall have crossed the Nile."
"If God wills," said Trench. "If only He wills," and he glanced about him in a fear which only increased the nearer they drew towards safety. They were in a country traversed by the caravans; it was no longer safe to travel by day. They dismounted, and all that day they lay hidden behind a belt of shrubs upon some high ground and watched the road and the people like specks moving along it. They came down and crossed it in the darkness, and for the rest of that night travelled hard towards the river. As the day broke Abou Fatma again bade them halt. They were in a desolate open country, whereon the smallest protection was magnified by the surrounding flatness. Feversham and Trench gazed eagerly to their right. Somewhere in that direction and within the range of their eyesight flowed the Nile, but they could not see it.
"We must build a circle of stones," said Abou Fatma, "and you must lie close to the ground within it. I will go forward to the river, and see that the boat is ready and that our friends are prepared for us. I shall come back after dark."
They gathered the stones quickly and made a low wall about a foot high; within this wall Feversham and Trench laid themselves down upon the ground with a water-skin and their rifles at their sides.
"You have dates, too," said Abou Fatma.
"Yes."
"Then do not stir from the hiding-place till I come back. I will take your camels, and bring you back fresh ones in the evening." And in company with his fellow-Arab he rode off towards the river.
Trench and Feversham dug out the sand within the stones and lay down, watching the horizon between the interstices. For both of them this perhaps was the longest day of their lives. They were so near to safety and yet not safe. To Trench's thinking it was longer than a night in the House of Stone, and to Feversham longer than even one of those days six years back when he had sat in his rooms above St. James's Park and waited for the night to fall before he dared venture out into the streets. They were so near to Berber, and the pursuit must needs be close behind. Feversham lay wondering how he had ever found the courage to venture himself in Berber. They had no shade to protect them; all day the sun burnt pitilessly upon their backs, and within the narrow circle of stones they had no room wherein to move. They spoke hardly at all. The sunset, however, came at the last, the friendly darkness gathered about them, and a cool wind rustled through the darkness across the desert.
"Listen!" said Trench; and both men as they strained their ears heard the soft padding of camels very near at hand. A moment later a low whistle brought them out of their shelter.
"We are here," said Feversham, quietly.
"God be thanked!" said Abou Fatma. "I have good news for you, and bad news too. The boat is ready, our friends are waiting for us, camels are prepared for you on the caravan track by the river-bank to Abu Hamed. But your escape is known, and the roads and the ferries are closely watched. Before sunrise we must have struck inland from the eastern bank of the Nile."
They crossed the river cautiously about one o'clock of the morning, and sank the boat upon the far side of the stream. The camels were waiting for them, and they travelled inland and more slowly than suited the anxiety of the fugitives. For the ground was thickly covered with boulders, and the camels could seldom proceed at any pace faster than a walk. And all through the next day they lay hidden again within a ring of stones while the camels were removed to some high ground where they could graze. During the next night, however, they made good progress, and, coming to the groves of Abu Hamed in two days, rested for twelve hours there and mounted upon a fresh relay. From Abu Hamed their road lay across the great Nubian Desert.
Nowadays the traveller may journey through the two hundred and forty miles of that waterless plain of coal-black rocks and yellow sand, and sleep in his berth upon the way. The morning will show to him, perhaps, a tent, a great pile of coal, a water tank, and a number painted on a white signboard, and the stoppage of the train will inform him that he has come to a station. Let him put his head from the window, he will see the long line of telegraph poles reaching from the sky's rim behind him to the sky's rim in front, and huddling together, as it seems, with less and less space between them the farther they are away. Twelve hours will enclose the beginning and the end of his journey, unless the engine break down or the rail be blocked. But in the days when Feversham and Trench escaped from Omdurman progression was not so easy a matter. They kept eastward of the present railway and along the line of wells among the hills. And on the second night of this stage of their journey Trench shook Feversham by the shoulders and waked him up.
"Look," he said, and he pointed to the south. "To-night there's no Southern Cross." His voice broke with emotion. "For six years, for every night of six years, until this night, I have seen the Southern Cross. How often have I lain awake watching it, wondering whether the night would ever come when I should not see those four slanting stars! I tell you, Feversham, this is the first moment when I have really dared to think that we should escape."
Both men sat up and watched the southern sky with prayers of thankfulness in their hearts; and when they fell asleep it was only to wake up again and again with a fear that they would after all still see that constellation blazing low down towards the earth, and to fall asleep again confident of the issue of their desert ride. At the end of seven days they came to Shof-el-Ain, a tiny well set in a barren valley between featureless ridges, and by the side of that well they camped. They were in the country of the Amrab Arabs, and had come to an end of their peril.
