ud and the third dervish on the
ground, struggling in each other's arms. He started forward, but before
he could reach the two, Mahmoud jumped to his feet with a reeking knife,
and waved it in the air.

"He was a kinsman, but he had to die," said Mahmoud as they mounted.
He turned towards the bodies, then looked at the camels flying down the
desert towards Dongola.

"It is as God wills now," he said. "Their tribesmen will follow when
they see the camels. See, my camel is wounded!" he added, with a gasp.

Two days following, towards evening, two wounded men on foot trudged
through the desert haggard and bent. The feet of one--an Arab--had on
a pair of red slippers, the feet of the other were bare. Mahmoud and
Macnamara were in a bad way. They were in very truth "walking against
time." Their tongues were thick in their mouths, their feet were
lacerated and bleeding, they carried nothing now save their pistols
and their swords, and a small bag of dates hanging at Macnamara's belt.
Prepared for the worst, they trudged on with blind hope, eager to die
fighting if they must die, rather than to perish of hunger and thirst
in the desert. Another day, and they would be beyond the radius of the
Khalifa's power: but would they see another day?

They thought that question answered, when, out of the evening pink and
opal and the golden sand behind them, they saw three Arabs riding. The
friends of the slain dervishes were come to take revenge, it seemed.

The two men looked at each other, but they did not try to speak.
Macnamara took from his shirt a bag of gold and offered it to Mahmoud.
It was the balance of the payment promised to Ebn Mazar. Mahmoud
salaamed and shook his head, then in a thick voice: "It is my life and
thy life. If thou diest, I die. If thou livest, the gold is Ebn Haraf's.
At Wady Halfa I will claim it, if it be the will of God."

The words were thick and broken, but Macnamara understood him, and they
turned and faced their pursuers, ready for life or death, intent to
kill--and met the friends of Ebn Haraf, who had been hired to take them
on to Wady Halfa! Their rescuers had been pursued, and had made a detour
and forced march, thus coming on them before the time appointed. In
three days more they were at Wady Halfa.

Mahmoud lived to take back to Ebn Mazar the other hundred pounds of the
gold Macnamara had looted from the Khalifa; and he also took something
for himself from the British officers at
