About twenty men were employed on this work. Sergeant Süssmilch had the general supervision of it, and indeed, I being the only prisoner under his immediate charge, had nothing else to do, the convicts from the penitentiary being under the charge of two overseers. The most of these convicts, of whom the majority were young men, and all strong and well fitted for such work, looked as any men would look dressed in coarse drilling, working under the eyes of a pair of stalwart overseers, and forbidden to smoke, to whistle, to sing, or to speak in a low tone. This latter prohibition first struck me upon hearing Süssmilch give to one who had attempted to open a private conversation with his neighbor, in a very emphatic tone the warning: "One has no secrets here; one can talk loud or hold his tongue."

This warning was most frequently given to one particular convict, with the additional remark that he had every reason to be careful.

This was a fellow of Herculean frame, the only one that had what might be called a thorough gallows-face, and who owed his precious life only to the circumstance that a murder of which he was most vehemently suspected, could not quite be brought home to him in the eyes of the judges. He was named Kaspar, and his fellow-convicts called him Cat-Kaspar, because he was believed to possess the mysterious faculty of seeing in the dark as well as in broad daylight, and, notwithstanding the gigantic breadth of his shoulders, of creeping through holes only large enough to allow the passage of a cat.

From the very first day I had made a conquest of this richly-gifted man. While the others watched me with suspicious side-glances, never spoke a word to me, and visibly avoided me, Cat-Kaspar sought every opportunity to be near me; made furtive signals with his eyes, first looking at me and then at the overseers, and gave me in every way to understand that he wished to enter into more intimate relations, and especially that he wished to speak with me.

I confess that I felt the strongest abhorrence for the man, whose nature was plainly enough indicated by a low forehead almost covered by his hair, a pair of evil, poisonous eyes, and a great brutal mouth; and any one would have felt the impulse to shun him even without the knowledge that his hands were stained with blood. But I mastered this instinctive aversion, for I said to myself that this man would have decision enough for any venture, and dexterity and strength enough to carry out any plan. So I also sought an opportunity to get near him, but did not succeed until we had been working together for a fortnight. I had hardly effected this, when I made the discovery that Cat-Kaspar, in addition to the accomplishments of which I had heard, possessed another, which I afterwards found out to be easily acquired. This art consisted in a most perfect imitation of a yawn, and while holding the hand to the open mouth, forming by means of the tongue and teeth certain sounds which, when closely listened to, could be detected to be words. Thus for the first time I heard, to my no small astonishment, from the midst of the most natural yawn in the world, the words: "The great stone--help me."

What he meant I learned a few minutes later.

They had recently been hauling stone for the foundations, and a particularly large one, through the clumsiness of the wagoners, had rolled into the foundation at a place where it was not needed. It seemed a matter of impossibility to get it out again without erecting apparatus for the purpose. Sergeant Süssmilch swore at their cursed stupidity, which would now cause an hour or more of unnecessary work. Cat-Kaspar, after he had given me the mysterious hint, suddenly raised his voice and said:

"What is the great difficulty, Herr Süssmilch? I will undertake it, single-handed."

"Yes, if a big mouth could do it," growled Herr Süssmilch.

The rest laughed. Cat-Kaspar called them a pack of toadies, and said that it was an easy thing to crack jokes and laugh at an honest fellow who was not allowed to show what he could do.
