Suddenly turning round I observed that I was alone.

Well, well, I thought; I have been going too fast, or Hans and my uncle have stopped on the way. Come, this won’t do; I must join them. Fortunately there is not much of an ascent.

I retraced my steps. I walked for a quarter of an hour. I gazed into the darkness. I shouted. No reply: my voice was lost in the midst of the cavernous echoes which alone replied to my call.

I began to feel uneasy. A shudder ran through me.

“Calmly!” I said aloud to myself, “I am sure to find my companions again. There are not two roads. I was too far ahead. I will return!”

For half an hour I climbed up. I listened for a call, and in that dense atmosphere a voice could reach very far. But there was a dreary silence in all that long gallery. I stopped. I could not believe that I was lost. I was only bewildered for a time, not lost. I was sure I should find my way again.
