"Over a thousand years. There is only one more like it in the world, and no Christian eyes save four have ever looked upon it. When you take that box from the room, see that it is the last, Geoffrey. You hear?"

It was Ralph who spoke. He had appeared silently and mysteriously as usual. He spoke calmly, but his twitching lips were eloquent of suppressed excitement.

"Very well," Geoffrey said carelessly. He was getting used to these strange quick appearances and these equally strange requests. "It shall be as you desire, uncle."

Ralph nodded. He gave a swift turn of his head as if looking for some one unconsciously, then he crossed the room and stooped down beside the brass-bound box, which was at the bottom of a pile of packages. His long fingers felt over the quaint brasses.

"A most remarkable-looking pattern," said Geoffrey.

"It is not a pattern at all," Ralph replied.

"The quaint filigree work is a language—the written signs of old Tibet, only you are not supposed to know that; indeed, I only found it out myself a few days ago. It had been a long search; but, as I can only see with my fingers, you can understand that. But this is part of the secret."

Geoffrey was profoundly interested.

"Tell me what the language says?" he asked.

"Not now—perhaps not at all. It is a ghastly and terrible thing, and even your nerves are not fireproof. There is only one thing I have to ask you before I efface myself for the present. When you take up that box to carry it down stairs it is to slip through your fingers. You are to drop it."
