second week," she said, "we knew we were lost. We were deep in the heart of the range. All around us was a forest of enormous, snow-topped peaks. The gorges, the canyons, the valleys that we tried led us east and west, north and south.

"It was a maze, and in it we seemed to be going ever deeper. There was not the SLIGHTEST sign of human life. It was as though no human beings except ourselves had ever been there. Game was plentiful. We had no trouble in getting food. And sooner or later, of course, we were bound to find our way out. We didn't worry.

"It was five nights ago that we camped at the head of a lovely little valley. There was a mound that stood up like a tiny watch-tower, looking down it. The trees grew round like tall sentinels.

"We built our fire in that mound; and after we had eaten, Martin slept. I sat watching the beauty of the skies and of the shadowy vale. I heard no one approach—but something made me leap to my feet, look behind me.

"A man was standing just within the glow of firelight, watching me."

"A Tibetan?" I asked. She shook her head, trouble in her eyes.

"Not at all." Ventnor turned his head. "Ruth screamed and awakened me. I caught a glimpse of the fellow before he vanished.

"A short purple mantle hung from his shoulders. His chest was covered with fine chain mail. His legs were swathed and bound by the thongs of his high buskins. He carried a small, round, hide-covered shield and a short two-edged sword. His head was helmeted. He belonged, in fact—oh, at least twenty centuries back."

He laughed in plain enjoyment of our amazement.

"Go on, Ruth," he said, and took up his watch.
