pubOne.info thank you for your continued support and wish to present you this new edition. We are in the depths of an underground cavern. It is bad enough to be underground, but here we are all enveloped in black as well: the ceiling is black, so are the walls; they are made of blocks of coal. The floor is one great black looking-glass. It is a sort of pond, polished as steel. Over this polished surface glistens the reflection of a solitary light, the light of a safety-lamp shining through a wire net.
