“Yes, you are better, my boy,” said Mr Burne, nodding his head approvingly.

“I used to feel tired directly I moved,” continued Lawrence, “but now I scarcely ever feel tired till quite night. Yussuf says it is the mountain air.”

“But where does it lead?” said the professor.

“Away west, effendi—where, I cannot say; but let us get out of this place and I will lead you in safety somewhere.”
