He lighted his candle and examined it. Decayed and broken as it was, it was strongly secured in its place by hinges on the one side, and either lock or bolt, he could not tell which, on the other. A brief use of his pocket-knife was enough to make room for his hand and arm to get through, and then he found a great iron bolt--but so rusty that he could not move it. Lina whimpered. He took his knife again, made the hole bigger, and stood back. In she shot her small head and long neck, seized the bolt with her teeth, and dragged it, grating and complaining, back. A push then opened the door. It was at the foot of a short flight of steps. They ascended, and at the top Curdie found himself in a space which, from the echo to his stamp, appeared of some size, though of what sort he could not at first tell, for his hands, feeling about, came upon nothing. Presently, however, they fell on a great thing: it was a wine cask. He was just setting out to explore the place thoroughly, when he heard steps coming down a stair. He stood still, not knowing whether the door would open an inch from his nose or twenty yards behind his back. It did neither. He heard the key turn in the lock, and a stream of light shot in, ruining the darkness, about fifteen yards away on his right. A man carrying a candle in one hand and a large silver flagon in the other, entered, and came toward him. The light revealed a row of huge wine casks, that stretched away into the darkness of the other end of the long vault. Curdie retreated into the recess of the stair, and peeping round the corner of it, watched him, thinking what he could do to prevent him from locking them in. He came on and on, until curdie feared he would pass the recess and see them. He was just preparing to rush out, and master him before he should give alarm, not in the least knowing what he should do next, when, to his relief, the man stopped at the third cask from where he stood. He set down his light on the top of it, removed what seemed a large vent-peg, and poured into the cask a quantity of something from the flagon. Then he turned to the next cask, drew some wine, rinsed the flagon, threw the wine away, drew and rinsed and threw away again, then drew and drank, draining to the bottom. Last of all, he filled the flagon from the cask he had first visited, replaced then the vent-peg, took up his candle, and turned toward the door. 'There is something wrong here!' thought Curdie. 'Speak to him, Lina,' he whispered.
