In Unorna he had found the instrument he had sought throughout half a lifetime. With her he had tried the great experiment and pushed it to the very end; and when he conducted Israel Kafka to his home, he already knew that the experiment had succeeded. His plan was a simple one. He would wait a few months longer for the final result, he would select his victim, and with Unorna’s help he would himself grow young again. “And who can tell,” he asked himself, “whether the life restored by such means may not be more resisting and stronger against deathly influences than before? Is it not true that the older we grow the more slowly we grow old? Is not the gulf which divides the infant from the man of twenty years far wider than that which lies between the twentieth and the fortieth years, and that again more full of rapid change than the third score? Take, too, the wisdom of my old age as against the folly of a scarce grown boy, shall not my knowledge and care and forethought avail to make the same material last longer on the second trial than on the first?” No doubt of that, he thought, as he walked briskly along the pavement and entered his own house. In his great room he sat down by the table and fell into a long meditation upon the most immediate consequences of his success in the difficult undertaking he had so skilfully brought to a conclusion. His eyes wandered about the room from one specimen to another, and from time to time a short, scornful laugh made his white beard quiver. As he had said once to Unorna, the dead things reminded him of many failures; but he had never before been able to laugh at them and at the unsuccessful efforts they represented. It was different to-day. Without lifting his head he turned up his bright eyes, under the thick, finely-wrinkled lids, as though looking upward toward that Power against which he strove. The glance was malignant and defiant, human and yet half-devilish. Then he looked down again, and again fell into deep thought. “And if it is to be so,” he said at last, rising suddenly and letting his open hand fall upon the table, “even then, I am provided. She cannot free herself from that bargain, at all events.” Then he wrapped his furs around him and went out again. Scarce a hundred paces from Unorna’s door he met the Wanderer. He looked up into the cold, calm face, and put out his hand, with a greeting. “You look as though you were in a very peaceful frame of mind,” observed Keyork. “Why should I be anything but peaceful?” asked the other, “I have nothing to disturb me.” “True, true. You possess a very fine organisation. I envy you your magnificent constitution, my dear friend. I would like to have some of it, and grow young again.” “On your principle of embalming the living, I suppose.” “Exactly,” answered the sage with a deep, rolling laugh. “By the bye, have you been with our friend Unorna? I suppose that is a legitimate question, though you always tell me I am tactless.”
