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.
