ght, and even if it takes time it will be the surest way.
Ibrahim says that if the Hakim performs a few cures as we get nearer,
the news thereof will reach the Khalifa's camp, where men die off in
hundreds, and after a time he will be sure to send for us. Just think
of the difference in our reception."

Frank nodded.

"In the one case we should be received with suspicion and most probably
turned back, perhaps be made prisoners; while, if at the new Mahdi's
wish we are sent for, we go there in triumph, and are respected and well
treated by everyone."

"Yes, yes; but the time will be passing away so swiftly, and that poor
fellow lying in agony and despair."

"Yes, but the more reason for being cautious. We must not build the
castle of our hopes upon the sand, Frank. I know it seems very hard,
and no doubt I sound cold-blooded for agreeing so readily to this Arab's
proposals, but I speak from ten years' experience of the old fellow. He
has thrown himself heart and soul into the adventure, and he is well
worthy of our trust; so, even at the expense of going against your own
wishes now and then, give way and follow out the old man's advice, even
when he would be ready to give way to you."

"I'll do my best," said Frank; "but it seems to me that I have already
bound _myself_ down to profound obedience in all things by undertaking
to go as a slave."

"Well, yes, that does bind you, certainly," said the professor.

"Well, let's talk about something else. We are bound now for the
Sheikh's encampment. What is going to be done first when we get there?"

"We put off Europe and put on Africa as far as is necessary."

"Hah!" said Frank, with a sigh.

"What does that mean, my lad?" said the professor sternly. "Are you
beginning to repent?"

"Repent!" said Frank between his teeth. "What a question! I am longing
to commence, for so far everything has been preparation."

"And a very brief preparation," said the professor, "if you come to
think of how short a time it is since you dashed in upon us after dinner
that evening with your news."

"Well, don't reproach me, Landon."

"Not I, my lad. I know what you must feel. All I want of you now is
for you to play the stoic. Make up your mind that
