One day, toward the close of last September, an old man rapped at my office door, and on invitation came in, and advancing, called me by name. Perceiving that I did not at first recognize him, he introduced himself as Gregory Summerfield. After inviting him to a seat, I scrutinized his features more closely, and quickly identified him as the same person whom I had met twenty-two years before. He was greatly altered in appearance, but the lofty forehead and the gray eye were still there, unchanged and unchangeable. He was not quite so stout, but more ruddy in complexion, and exhibited some symptoms, as I then thought, of intemperate drinking. Still there was the old charm of intellectual superiority in his conversation, and I welcomed him to California as an important addition to her mental wealth.

It was not many minutes before he requested a private interview. He followed me into my back office, carefully closed the door after him and locked it. We had scarcely seated ourselves before he inquired of me if I had noticed any recent articles in the newspapers respecting the discovery of the art of decomposing water so as to fit it for use as a fuel for ordinary purposes?

I replied that I had observed nothing new upon that subject since the experiments of Agassiz and Professor Henry, and added that, in my opinion, the expensive mode of reduction would always prevent its use.

In a few words he then informed me that he had made the discovery that the art was extremely simple, and the expense attending the decomposition so slight as to be insignificant.

Presuming then that the object of his visit to me was to procure the necessary forms to get out a patent for the right, I congratulated him upon his good fortune, and was about to branch forth with a description of some of the great benefits that must ensue to the community, when he suddenly and somewhat uncivilly requested me to "be silent," and listen to what he had to say.

He began with some general remarks about the inequality of fortune amongst mankind, and instanced himself as a striking example of the fate of those men, who, according to all the rules of right, ought to be near the top, instead of at the foot of the ladder of fortune. "But," said he, springing to his feet with impulsive energy, "I have now the means at my command of rising superior to fate, or of inflicting incalculable ills upon the whole human race."

Looking at him more closely, I thought I could detect in his eye the gleam of madness; but I remained silent and awaited further developments. But my scrutiny, stolen as it was, had been detected, and he replied at once to the expression of my face: "No, sir; I am neither drunk nor a maniac; I am in deep earnest in all that I say; and I am fully prepared, by actual experiment, to demonstrate beyond all doubt the truth of all I claim."

For the first time I noticed that he carried a small portmanteau in his hand; this he placed upon the table, unlocked it, and took out two or three small volumes, a pamphlet or two, and a small, square, wide-mouthed vial, hermetically sealed.

I watched him with profound curiosity, and took note of his slightest movements. Having arranged his books to suit him, and placed the vial in a conspicuous position, he drew up his chair very closely to my own, and uttered in a half-hissing tone: "I demand one million dollars for the contents of that bottle; and you must raise it for me in the city of San Francisco within one month, or scenes too terrible even for the imagination to conceive, will surely be witnessed by every living human being on the face of the globe."

The tone, the manner, and the absurd extravagance of the demand, excited a faint smile upon my lips, which he observed, but disdained to notice.
