My Chinaman went forward, and rapped four times on one of the walls. A whole section of the wall swung out, leaving a narrow doorway. I passed through, and to my utter astonishment found myself in a kind of Arabian Nights’ palace. A low long subterranean chamber hung with rich oriental silks, brilliantly lighted and fragrant with perfumes and spices. There were five or six silk-covered divans, and exquisite carpets of Chinese workmanship covered the ground. At the end of the room was a curtained recess. From behind these curtains came a voice.

“You have brought our honoured guest?”

“Excellency, he is here,” replied my guide.

“Let our guest enter,” was the answer.

At the same moment, the curtains were drawn aside by an unseen hand, and I was facing an immense cushioned divan on which sat a tall thin Oriental dressed in wonderfully embroidered robes, and clearly, by the length of his fingernails, a great man.
