He hurried on, feeling his way along the walls of rock. Had he not been very courageous, he must have been very anxious, for he could not but know that if he lost his way it would be the most difficult thing in the world to find it again. Morning would bring no light into these regions; and toward him least of all, who was known as a special rhymster and persecutor, could goblins be expected to exercise courtesy? Well might he wish that he had brought his lamp and tinder-box with him, of which he had not thought when he crept so eagerly after the goblins! He wished it all the more when, after a while, he found his way blocked up, and could get no farther. It was of no use to turn back, for he had not the least idea where he had begun to go wrong. Mechanically, however, he kept feeling about the walls that hemmed him in. His hand came upon a place where a tiny stream of water was running down the face of the rock. "What a stupid I am!" he said to himself. "I am actually at the end of my journey!--and there are the goblins coming back to fetch their things!" he added, as the red glimmer of their torches appeared at the end of the long avenue that led up to the cave. In a moment he had thrown himself on the floor, and wriggled backward through the hole. The floor on the other side was several feet lower, which made it easier to get back. It was all he could do to lift the largest stone he had taken out of the hole, but he did manage to shove it in again. He sat down on the ore-heap and thought. He was pretty sure that the latter plan of the goblins was to inundate the mine by breaking outlets for the water accumulated in the natural reservoirs of the mountain, as well as running through portions of it. While the part hollowed by the miners remained shut off from that inhabited by the goblins, they had had no opportunity of injuring them thus; but now that a passage was broken through, and the goblins' part proved the higher in the mountain, it was clear to Curdie that the mine could be destroyed in an hour. Water was always the chief danger to which the miners were exposed. They met with a little choke-damp sometimes, but never with the explosive fire-damp so common in coal mines. Hence they were careful as soon as they saw any appearance of water.
