He arose and tried to walk, but he was so dizzy that he had to sit down again. He felt better after a little, though, very much better than before he had taken his rest. He wondered how long he had slept, and what progress was being made, if any, toward his rescue. He went down to the opening in the wall, and held his lamp up to it. Threads of smoke were still curling in through the slate and culm, and the air that crept in was very bad. Then, for a little time, Ralph sat there and listened. He thought that possibly he might hear some distant sound of rescue. But there was no noise; the silence was burdensome.

His thirst increased and he was hot and feverish.

At last he rose with the determination to carry out his plan of searching for the old slope.

He knew that it would be worse than useless to stay here.

Besides, he hoped that he might find a stream of water on the way at which to quench his thirst.

He thought of the letter in his pocket, and the desire grew strong within him to read it again. He took it out, unfolded it, and held it close to the light, but there seemed to be a mist before his eyes and he could not distinguish the words. He knew what it contained, though, and that was sufficient for him. He was Robert Burnham's son. His father had been brave and manly; so would he be. His father would have kept up heart and courage to the end, no matter what fate faced him. He determined that the son should do no less. He would be worthy of his parentage, he would do all that lay in his power to accomplish his own safety; if he failed, the fault should not be his.

He folded and replaced the letter, picked up his oil-can, fastened his lamp to his cap and started down the chamber. He felt that he was strong with the strength of inspiration. It seemed to him, too, that he was very light in body. It seemed almost as though he were treading on air, and he thought that he was moving very fast.

In reality his steps were heavy and halting, and his way down the long chamber was devious and erratic. His fancied strength and elasticity were born of the fever in his blood.

He came to the heading. He knew, now, which way to turn, and he passed down it in what he thought was rapid flight.

But here was the fall again. What was to be done now? His last attempt to get around it had been disastrous. He would not try that plan again. He would work his way through it this time and keep to the heading.
