“If you are really willing to admit failure,” he began slowly, carefully selecting each word, “if behind your wish there lies a sincere desire to go back to youth and begin life over, if that desire is strong enough to grow into a purpose, if you are ready to make the experiment, there you will find the means. That vial contains the very essence of vitality, the true elixir of youth. It is not a magic philter, as I see by your thought you believe. There is no magic. Whatever is, belongs to science. I am not a necromancer, but a scientist. From boyhood my study has been to solve the subtler secrets of life. I have solved many such. I have solved at last the secret of life itself. It is contained in that golden vial, an elixir to renew the tissues, to repair the cells, of the wasting body. Taken as I direct, you will no longer grow old, but young. The gray in your hair will vanish, the lines will smooth out of your face, your step will become buoyant, your pulses quick, your heart will sing with youth.” The speaker paused a moment, and his gray eyes rested on Carringford and seemed probing his very soul.

“It will take a little time,” he went on; “for as the natural processes of decay are not rapid, the natural restoration may not be hurried. You can go back to where you will, even to early youth, and so begin over, if it is your wish. Are you willing to make the experiment? If you are, I will place the means in your hands.”

While his visitor had been speaking, Carringford had been completely absorbed, filled with strange emotions, too amazed, too confused for utterance.

“I see a doubt in your mind as to the genuineness, the efficacy, of my discovery,” the even voice continued. “I will relieve that.” From an inner pocket he drew a card photograph and handed it to Carringford. “That was taken three years ago. I was then approaching eighty. I am now, I should say, about forty-five. I could be younger if I chose, but forty-five is the age of achievement—the ripe age. Mankind needs me at forty-five.”

Carringford stared at the photograph, then at the face before him, then again at the photograph. Yes, they were the same, certainly they were the same, but for the difference of years. The peculiar eyes, the clean, unusual outlines were unmistakable. Even a curious cast in the eye was there.

“An inheritance,” explained his visitor. “Is the identification enough?”

Carringford nodded in a dazed way and handed back the picture. Any lingering doubt of the genuineness of this strange being or his science had vanished. His one thought now was that growing old need be no more than a fiction, after all that one might grow young instead, might lay aside the wrinkles and the gray hairs, and walk once more the way of purposes and dreams. His pulses leaped, his blood surged up and smothered him.

The acceptance of such a boon seemed too wonderful a thing to be put into words. His eyes grew wide and deep with the very bigness of it, but he could not for the moment find speech.

“You are willing to make the experiment?” the man asked. “I see many emotions in your mind. Think—think clearly, and make your decision.”

Words of acceptance rushed to Carringford’s lips. They were upon the verge of utterance when suddenly he was gripped by an old and dearly acquired habit—the habit of forethought.
