"You may go," said Mr Query. "You have worked enough for to-day." He handed her several pieces of gold. Her eyes sparkled with glee as she pocketed the coins; she was proud of having earned some money.

"Follow me," she said to Karl, "and I will show you the way home. You would never be able to find it alone."

"The dwarfs have burrowed here like moles," said Karl aside to the girl, "and I believe they are almost as blind and ignorant."

"Do not speak disrespectfully of moles," said a dwarf who had overheard the last part of this remark. "They belong to the most intelligent of all creatures; who can build a fortress like the mole?"

"Norah," said the dwarfs, "Norah, when are you coming again?"

"Very soon," she said, "I'll bring some metal polish with me, and make your vases shine!"

"Norah," thought Karl, "so that is her name. I wonder where she lives?"

Norah led the way back through intricate passages until they came to the open space where there was the staircase leading up to the outside world. "Good morning," she said to the dwarfs.

Karl pulled out his watch—yes—the night was already past, it was four o'clock.
