Sir Richard slipped the packet into his pocket with a rather uncertain smile, and turned to the matter of transit without loss of time.

Anstice's horse was the fresher of the two, and it was decided that Sir Richard should start at once, and when at a safe distance dismount and rest until moonrise, after which the night hours might profitably be spent in journeying onwards, since night-riding in the desert is infinitely preferable to riding by day.

"With luck you should make Cairo very early on the day after to-morrow," said Anstice, who had been making a calculation. "And if you could get started again without loss of time you could be here in just under three days. But that would mean hard riding, I'm afraid——"

"I'm pretty tough," said Sir Richard again. "And after all you'll have the harder part. I suppose"—he turned to Hassan—"I suppose there is no possibility of getting help nearer than Cairo—no village or settlement to which I might apply?"

No, Hassan opined, it was of no use seeking help elsewhere. The one or two native villages within call were quite inadequate to render assistance, and to apply to them would be a loss of time which would have no practical result.

When once Sir Richard was assured of the impossibility of procuring help nearer than Cairo he wasted no further time in discussion, but mounted his horse with a businesslike air and proceeded to take leave of Anstice with a heartiness which but thinly disguised his real and gnawing anxiety.

"I will make all possible speed," he said, as he settled himself sturdily in his saddle. "And with luck three days should see me back. In the meantime"—for a moment his voice faltered, but he pulled himself together pluckily—"I leave my girl in your care. And I know"—Sir Richard spoke very slowly—"I know you will guard her, if need be, with your life...."

"Thank you for your trust, Sir Richard." In Anstice's hand-grip Sir Richard read the measure of his resolve. "I will not fail you—nor your daughter—so long as I am alive."

Sir Richard wrung his hand, tried to speak, and failed, utterly, to articulate a syllable. But the look which the two men exchanged spoke more eloquently than words, and Sir Richard, as he rode away on his mission, knew that so far as mortal man might compass success his daughter's safety was assured at this man's hands.
