"You lose all sense of direction in this labyrinth," I muttered to Morhange.

"Worse still, you will lose your head," answered my companion sotto voce. "This old fool is certainly very learned; but God knows what he is driving at. However, he has promised that we are soon to know."

M. Le Mesge had stopped before a heavy dark door, all incrusted with strange symbols. Turning the lock with difficulty, he opened it.

"Enter, gentlemen, I beg you," he said.

A gust of cold air struck us full in the face. The room we were entering was chill as a vault.

At first, the darkness allowed me to form no idea of its proportions. The lighting, purposely subdued, consisted of twelve enormous copper lamps, placed column-like upon the ground and burning with brilliant red flames. As we entered,

the wind from the corridor made the flames flicker, momentarily casting about us our own enlarged and misshapen shadows. Then the gust died down, and the flames, no longer flurried, again licked up the darkness with their motionless red tongues.

These twelve giant lamps (each one about ten feet high) were arranged in a kind of crown, the diameter of which must have been about fifty feet. In the center of this circle was a dark mass, all streaked with trembling red reflections. When I drew nearer, I saw it was a bubbling fountain. It was the freshness of this water which had maintained the temperature of which I have spoken.

Huge seats were cut in the central rock from which gushed the murmuring, shadowy fountain. They were heaped with silky cushions. Twelve incense burners, within the circle of red lamps, formed a second crown, half as large in diameter. Their smoke mounted toward the vault, invisible in the darkness, but their perfume, combined with the coolness and sound of the water, banished from the soul all other desire than to remain there forever.

M. Le Mesge made us sit down in the center of the hall, on the Cyclopean seats. He seated himself between us.
