But it was of no use. They could not find their way back to the starting place, and they could not find the opening of the mine. They had used two of the slow burning candles and they had only half a dozen or so left. When these were gone-- But they did not like to think of that, and stumbled on and on. They did not talk much, for they were too worried. Finally Ned gasped: "I'd give a good deal for a drink of water." "So would I," added his chum. "But what's the use of wishing? If there was a spring down here it would be salt water. But I know what I would do--if I could." "What?" asked Mr. Damon. "Go back to the prison. At least we wouldn't starve there, and we'd have something to drink. If they kept us we know we could get free--sometime." "Perhaps never!" exclaimed Ivan Petrofsky. "It is better to keep on here, and, as for me, I would rather die here than go back to a Russian prison. We must--we shall get out!" But it was idle talk. Gradually they lost track of time as they staggered on, and they hardly knew whether a day had passed or whether it was but a few hours since they had been lost. Of their sufferings in that salt mine I shall not go into details. There are enough unpleasant things in this world without telling about that. They must have wandered around for at least a day and a half, and in all that while they had not a drop of water, and not a thing to eat. Wait, though, at last in their desperation they did gnaw the tallow candles, and that served to keep them alive, and, in a measure, alleviate their awful sufferings from thirst. Back and forth they wandered, up and down in the galleries of the old salt mine. They were merely hoping against hope. "It's worse than the underground city of gold," said Ned in hollow tones, as he staggered on. "Worse--much worse." His head was feeling light. No one answered him. It was, as they learned later, just about two days after the time when they entered the mine that they managed to get out. Forty-eight hours, most of them of intense suffering. They were burning their last candle, and when that was out they knew they would have the horrors of darkness to fight against, as well as those of hunger and thirst. But fate was kind to them. How they managed to hit on the right gallery they did not know, but, as they made a turn around an immense pillar of salt Tom, who was walking weakly in advance, suddenly stopped. "Look! Look!" he whispered. "Another candle! Someone--someone is searching for us! We are saved!" "It may be the police!" said Ned. "That is not a candle," spoke the Russian in hollow tones as he looked to where Tom pointed, to a little glimmer of light. "It is a star. Friends, we are saved, and by Providence! That is a star, shining through the opening of the mine. We are saved!" Eagerly they pressed forward, and they had not gone far before they knew that the exile was right. They felt the cool night wind on their hot cheeks.
