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.

"We are safe," cried Abou Fatma. "God is good. Northwards to Assouan, westwards to Wadi Halfa, we are safe!" And spreading a cloth upon the ground in front of the kneeling camels, he heaped dhurra before them. He even went so far in his gratitude as to pat one of the animals upon the neck, and it immediately turned upon him and snarled.

Trench reached out his hand to Feversham.

"Thank you," he said simply.

"No need of thanks," answered Feversham, and he did not take the hand. "I served myself from first to last."

"You have learned the churlishness of a camel," cried Trench. "A camel will carry you where you want to go, will carry you till it drops dead, and yet if you show your gratitude it resents and bites. Hang it all, Feversham, there's my hand."

Feversham untied a knot in the breast of his jibbeh and took out three white feathers, two small, the feathers of a heron, the other large, an ostrich feather broken from a fan.
