The more he considered his situation, the more free from all immediate danger did it seem, and the more did his hopes increase. He looked forward with eager hope, to the following day. That would, without doubt, bring him news of his friends, or, perhaps, restore him to liberty. Under the pleasant influence of thoughts like these, his mind grew more calm and cheerful every moment, and passed into a state of tranquil contentment Besides, he was tired, and his weariness brought on drowsiness. As long as his excitement lasted, he could not feel the drowsiness; but now, as calmness returned, the weariness and sleepiness became stronger, and by degrees overpowered him. Gradually the thoughts of his mind became intermingled with the fancies of dreams, and blended the realities around him with things at a distance. All was still, outside and inside. No sound whatever arose from below. The family seemed all asleep. At last Bob dozed off also, and passed into the land of dreams. His sleep was not heavy. Many things conspired to keep his senses somewhat on the alert even in that slumber of his, and he was in that condition which is called sleeping with one eye open. The fact is, the extraordinary excitement of his donkey ride, and especially of his last adventure in thus falling into captivity, had so roused his faculties, so affected his nerves, and so sharpened his senses, that even in his sleep there still predominated the thoughts and the purposes of his waking hours. In this state he remained for some time, sleeping, yet vigilant, the body gaining rest and refreshment, but the wary soul on the alert, as though to guard against danger. How long this sleep continued, whether minutes or hours, Bob could never afterwards remember; but with a sudden shock through all his nerves, he opened his eyes. He was lying, as he had flung himself on the straw, on his back, with his head elevated against a bundle of straw, in such a way that he could see the length of the room. It was a noise that he heard. He listened breathlessly, and looked with all his eyes. Around him all was dark. It might be near morning, or it might be early night; he could not tell. All was still, outside and inside--the blackness of darkness and the stillness of death. Yet now, in the midst of that black darkness and that deathly stillness, he became aware, of a sight and a sound. It was a low, creaking sound, which was repeated at short intervals, accompanied by a sliding, shuffling noise. It sounded in the direction of the opening by which the ladder led up from below. Looking there, he saw a ray of light, faint and flickering, yet visible enough in that deep darkness; and as the grating, shuffling sounds succeeded one another at regular intervals, even so did the faint, flickering ray of light grow brighter and brighter. As Bob looked at this and took it all in, one thought came to him in an instant,-- _Somebody was coming up the ladder!_
