ou can't stop it we shall have all the Emir's people
noticing it. Hadn't you better pretend as you've cured him, sir, and
made him speak? If you don't we shall be having the cat let out of the
bag, and all be scratched to death."

"Let's see, Samuel," said the doctor quietly, and he followed his man
into the next room, to find Frank talking wildly.

He seemed to recognise his friend directly, and caught him by the arm.

"Look here," he said, "I have no time to advise you, Hal. Be thrown
from a horse; cut your forehead, or your leg. Do something that they
can see looks bad--something that will stain your white things with
blood. They will believe it then, and beg that you may be taken to the
Hakim.--Ah, what are you doing here? Why are you not curing the
Baggara's white slave?"

The doctor had taken his young friend's wrist and laid a cool hand upon
his burning, throbbing brow, with excellent effect, for Frank's loud
talking grew broken, then indistinct, and rapidly sank into a low,

"Hah!" said Sam softly; "it's wonderful, sir. To do that with just a

in a hole like that. If I get it he'll get better and help me.
Breath's hot, sir, but it don't smell nasty and fevery. P'r'aps it's
only being too much in the sun, after all."

"Thank you, Samuel," said the doctor, in his quiet, grave way, and he
patted the man gently on the shoulder.

"Thank me, sir?--Oh, here's Mr Landon, sir."

"Hullo, there!" said the professor, hurriedly entering; "what's the
matter? Don't say Frank's ill!"

"He is saying it for himself, my dear Fred," replied the doctor. "You
have had some experience of this sort of thing out here. Look at him.
He is calmer now, but he was talking wildly at random a few minutes

"What! Oh! Saint George and t
