He ate and slept many times before his labor was rewarded by the loosening of a single stone next to the hole. And again he ate and slept many times before a second stone was removed.
How long he worked at this he did not know, but the time passed more quickly now and his mind was so engrossed with his labors that he was almost happy.
During this time he did not neglect his exercising, but he slept less often. When the snakes came he had to stop his work, for they were continually passing in and out through the hole.
He wished that he knew how the food was brought to his cell, that he might know if there was danger that those who brought it could hear him scraping at the mortar in the wall, but as he never heard the food brought he hoped that those who brought it could not hear him and he was quite sure that they could not see him.
And so he worked on unceasingly until at last he had scratched away an opening large enough to admit his body, and then for a long time he sat before it, waiting, seeking to assure himself that he was master of his mind, for in this eternal night of solitude that had been his existence for how long he could not even guess, he realized that this adventure which he was facing had assumed such momentous proportions that once more he felt himself upon the brink of madness. And now he wanted to make sure that no matter what lay beyond that aperture he could meet it with calm nerves and a serene and sane mind, for he could not help but realize that keen disappointment might be lying in wait for him, since during all the long periods of his scratching and scraping since he had discovered the hole through which the snakes came into his cell he had realized that a hope of escape was the foundation of the desire that prompted him to prosecute the work. And though he expected to be disappointed he knew how cruel would be the blow when it fell.
With a touch that was almost a caress he let his fingers run slowly over the rough edges of the enlarged aperture. He inserted his head and shoulders into it and reached far out upon the other side, groping with a hand that found nothing, searching with eyes that saw nothing, and then he drew himself back into his dungeon and walked to its far end and sat down upon the floor and leaned back against the wall and waited—waited because he did not dare to pass that aperture to face some new discouragement.
It took him a long time to master himself, and then he waited again. But this time, after reasoned consideration of the matter that filled his mind.
He would wait until they brought his food and had taken away the empty receptacle—that he might be given a longer interval before possible discovery of his absence, in the event he did not return to his cell. And though he went often to the corner where the food was ordinarily deposited, it seemed an eternity before he found it there. And after he had eaten it, another eternity before the receptacle was taken away; but at last it was removed. And once again he crossed his cell and stood before the opening that led he knew not where.
This time he did not hesitate. He was master of his mind and nerves.
One after the other he put his feet through the aperture until he sat with his legs both upon the far side of the wall. Then, turning on his stomach, he started to lower himself, because he did not know where the floor might be, but he found it immediately, on the same level as his own. And an instant later he stood erect and if not free, at least no longer a prisoner within his own cell.
Cautiously he groped about him in the darkness, feeling his way a few inches at a time. This cell, he discovered, was much narrower than his own, but it was very long. By extending his hands in both directions he could touch both walls, and thus he advanced, placing a foot cautiously to feel each step before he took it.
He had brought with him from his cell the iron sliver that he had broken from the cover of the pot and with which he had scratched himself thus far toward freedom. And the possession of this bit of iron imparted to him a certain sense of security, since it meant that he was not entirely unarmed.
Presently, as he advanced, he became convinced that he was in a long corridor. One foot came in contact with a rough substance directly in the center of the tunnel. He took his hands from the walls and groped in front of him.
It was a rough-coated cylinder about eight inches in diameter that rose directly upward from the center of the tunnel, and his fingers quickly told him that it was the trunk of a tree with the bark still on, though worn off in patches.
Passing this column, which he guessed to be a support for a weak section of the roof of the tunnel, he continued on, but he had taken but a couple of steps when he came to a blank wall—the tunnel had come to an abrupt end.
Tanar's heart sank within him. His hopes had been rising with each forward step and now they were suddenly dashed to despair. Again and again his fingers ran over the cold wall that had halted his advance toward hoped for freedom, but there was no sign of break or crevice, and slowly he turned back toward his cell, passing the wooden column and retracing his steps in utter dejection. But as he moved sadly along he mustered all his spiritual forces, determined not to let his expected disappointment crush him. He would go back to his cell, but he would still continue to use the tunnel. It would be a respite from the monotony of his own four walls. It would extend the distance that he might walk and after all he would make it worth the effort that had been necessary to gain ingress to it.
Back in his own cell again he lay down to sleep, for he had denied himself sleep a great deal of late that he might prosecute the work upon which he had been engaged. When he awoke the snakes were with him again and his friend was tapping gently on his chest, and once again he took up the dull monotony of his existence, altered only by regular excursions into his new found domain, the black interior of which he came to know as well as he did his own cell, so that he walked briskly from the hole he had made to the wooden column at the far end of the tunnel, passed around it and walked back again at a brisk gait and with as much assurance as though he could see plainly, for he had counted the paces from one end to the other so many times that he knew to an instant when he had covered the distance from one extremity to the other.
He ate; he slept; he exercised; he played with his slimy, reptilian companion; and he paced the narrow tunnel of his discovery. And often when he passed around the wooden column at its far end, he speculated upon the real purpose of it.
Once he went to sleep in his own cell thinking about it, and when he awoke to the gentle tapping of the snake's snout upon his breast he sat up so suddenly that the reptile fell hissing to the flagging, for clear and sharp upon the threshold of his awakening mind stood an idea—a wonderful idea—why had he not thought of it before?
Excitedly he hastened to the opening leading into the tunnel. Snakes were passing through it, but he fought for precedence with the reptilian horde and tumbled through head first upon a bed of hissing snakes. Scrambling to his feet he almost ran the length of the corridor until his outstretched hands came in contact with the rough bole of the tree. There he stood quite some time, trembling like a leaf, and then, encircling the column with his arms and legs, he started to climb slowly and deliberately aloft. This was the idea that had seized him in its compelling grip upon his awakening.
