Here one side of the mountain had a great hole in it, like the mouth of a cavern, and the stairs stopped at the near edge of the floor and commenced ascending again at the opposite edge.

The opening in the mountain was on the side opposite to the Valley of Voe, and our travellers looked out upon a strange scene. Below them was a vast space, at the bottom of which was a black sea with rolling billows, through which little tongues of flame constantly shot up. Just above them, and almost on a level with their platform, were banks of rolling clouds which constantly shifted position and changed color. The blues and greys were very beautiful, and Dorothy noticed that on the cloud banks sat or reclined fleecy, shadowy forms of beautiful beings who must have been the Cloud Fairies. Mortals who stand upon the earth and look up at the sky cannot often distinguish these forms, but our friends were now so near to the clouds that they observed the dainty fairies very clearly.

“Are they real?” asked Zeb, in an awed voice.
