"What were you going to do at In-Salah?"

He was about to reply. But suddenly we saw him tremble. His eyes were fixed on a point of the cavern. We looked to see what it was. He had just seen the rock inscription which had so delighted Morhange an hour before.

"Do you know that?" Morhange asked him with keen curiosity.

The Targa did not speak a word but his eyes had a strange light.

"Do you know that?" insisted Morhange.

And he added:

"Antinea?"

"Antinea," repeated the man.

And he was silent.

"Why don't you answer the Captain?" I called out, with a strange feeling of rage sweeping over me.
