It was a strange tunnel; not rounded and of regular shape like the railway tunnels at home, but varying in width and height. In some places the roof was beyond the range of Tommy's feeble light; at others it came so low that she could not have stood upright. The floor was uneven, the walls were rugged, a recess here, a protuberance there. Clearly it had not been cut by the hands of men, but must be attributed to a freak of nature.
To Tommy, crawling inch by inch along the ground, it seemed that the tunnel would never end. How long it was, how many minutes or hours this painful progress continued, she was quite unable to guess. At last, with a cry of gladness, she saw a faint gleam of light beyond, and tried to advance more quickly, so as to gain liberty and fresh air. The light came through an aperture in the wall that appeared to be the end of the passage. It was high above the ground, and Tommy, standing on one foot, was just able to look through it. She thought that if she could only manage to heave herself up to it, the aperture was just wide enough to let her body through.
But first of all she must make sure that it led to safety. It was not full daylight outside; beyond the wall there appeared to be, not open space, but another confined chamber. Supposing she climbed up and got through, how far would she have to drop to reach the ground on the other side? and what if she should find herself only in another place from which escape would be no easier than from the pit?
To stand on one foot was fatiguing, and Tommy had to sit down and rest for a little. She had now recovered from her panic, and was ready to bend all her young wits upon the problem of escape. Presently a means occurred to her of discovering at least whether it would be safe for her to make an attempt to clamber through the aperture. She felt along the floor for a piece of rock, and standing up again, dropped it over the ledge. In an instant there came a faint thud, and immediately afterwards a great whirring and screaming. She was quick to infer that the ground was at some depth below the opening, and that the falling rock had disturbed a colony of birds of some kind. "Can I be at the top of a cliff?" she thought.
Plainly it was impossible to escape in this direction. The dashing of her hope almost made Tommy weep. She had done no good; indeed had only wasted time. There was nothing for it but to crawl back to the pit; and as she wearily crept through the passage despair seized upon her heart; she felt the choking sensation of helpless misery.
Her terror was even deepened when, on getting back to the pit, she found that it was now quite dark. Through the opening she could see the stars overhead, but there was no pleasure in watching them as she had many times watched them from the hut. She crouched upon the leaves, scarcely able to bear the throbbing pain in her foot; and when presently she fell asleep from sheer exhaustion, it was with a prayer on her lips: "God help me, and let me see my sisters again."
Pain and thirst awakened her several times before dawn. A slight shower fell during the night, and by catching the raindrops in her outspread palm she was able to moisten her parched lips. She also wetted her handkerchief and bound it about her inflamed ankle, thus easing the pain a little. When it was quite light overhead she began to shout again, her voice sounding very cracked and hoarse. Soon she had to give up even this; her tongue and the roof of her mouth were so dry that she could not utter a word. Then she lost all hope, and lying down sobbed herself to sleep.
When she awoke it was again dark. Her foot was much less painful, but she felt more hungry and thirsty than ever before in her life. If only she had filled her pocket with oranges before she saw that little brown face! Again the idea came to her of attempting to climb the side of the pit by cutting steps in the earth; but on feeling in her pocket she remembered that she had dropped her knife on the ground. Hobbling across the pit she felt along the walls, only to find, as before, that their slope made it quite impossible to clamber up. Then feeling that starvation must be her doom, she sank back and lay in a state of dreamy somnolence.
All at once she was startled into wakefulness by a faint sound somewhere above her. She sprang up. Sunlight was streaming through the opening; the sound came again. It was some one calling. Tommy tried to shout in answer, but the feeble croak that was all she could utter dismayed her. With help at hand, she might not be heard! The call above was now quite clear. It was coming nearer. She heard her own name. But the more she tried to call the less she seemed able to make a sound. The voice above began to recede. Then with a last desperate effort she did manage to produce a hoarse cry that she could scarcely believe came from her own throat, so strange it was. It seemed to have used up all the little strength she had left, and she fell exhausted to the ground, believing that the last chance of rescue had now utterly vanished.
