The snakes came usually while he slept, but since that first experience they no longer filled him with horror. And after a dozen repetitions of their visit they not only ceased to annoy him, but he came to look forward to their coming as a break in the deadly monotony of his solitude. He found that by stroking them and talking to them in low tones he could quiet their restless writhing. And after repeated recurrences of their visits he was confident that one of them had become almost a pet.

Of course in the darkness he could not differentiate one snake from another, but always he was awakened by the nose of one pounding gently upon his chest, and when he took it in his hands and stroked it, it made no effort to escape; not ever again did one of them strike him with its fangs after that first orgy of madness, during which he had thought and hoped that the reptiles were venomous.

It took him a long time to find the opening through which the reptiles found ingress to his cell, but at length, after diligent search, he discovered an aperture about eight inches in diameter, some three feet above the floor. Its sides were worn smooth by the countless passings of scaly bodies. He inserted his hand in the opening and feeling around discovered that the wall at this point was about a foot in thickness, and when he inserted his arm to the shoulder he could feel nothing in any direction beyond the wall. Perhaps there was another chamber there—another cell like his—or possibly the aperture opened into a deep pit that was filled with snakes. He thought of many explanations and the more he thought the more anxious he became to solve the riddle of the mysterious space beyond his cell. Thus did his mind occupy itself with trivial things, and the loneliness and the darkness and the silence exaggerated the importance of the matter beyond all reason until it became an obsession with him. During all his waking hours he thought about that hole in the wall and what lay beyond in the Stygian darkness which his eyes could not penetrate. He questioned the snake that rapped upon his chest, but it did not answer him and then he went to the hole in the wall and asked the hole. And he was on the point of becoming angry when it did not reply when his mind suddenly caught itself, and with a shudder he turned away, realizing that this way led to madness and that he must, above all else, remain master of his mind.

But still he did not abandon his speculation; only now he conducted it with reason and sanity, and at last he hit upon a shrewd plan.

When next his food was brought and he had devoured it he took the iron cover from the iron pot, which had contained it, and hurled it to the stone flagging of his cell, where it broke into several pieces. One of these was long and slender and had a sharp point, which was what he had hoped he would find in the débris of the broken cover. This piece he kept; the others he put back into the pot and then he went to the aperture in the wall and commenced to scratch, slowly, slowly, slowly at the hard mortar in which the stones around the hole were set.

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.
