When the galley landed at a greasy-looking quay of spongy rock a nightmare horde of toad-things wiggled out of the hatches, and two of them seized Carter and dragged him ashore. The smell and aspect of that city are beyond telling, and Carter held only scattered images of the tiled streets and black doorways and endless precipices of grey vertical walls without windows. At length he was dragged within a low doorway and made to climb infinite steps in pitch blackness. It was, apparently, all one to the toad-things whether it were light or dark. The odour of the place was intolerable, and when Carter was locked into a chamber and left alone he scarcely had strength to crawl around and ascertain its form and dimensions. It was circular, and about twenty feet across.
