On the 201st day of the year 3221 A.D., the professor of history at the University of Terra seated himself in front of the Visaphone and prepared to deliver the daily lecture to his class, the members of which resided in different portions of the earth.

The instrument before which he seated himself was very like a great window sash, on account of the fact that there were three or four hundred frosted glass squares visible. In a space at the center, not occupied by any of these glass squares, was a dark oblong area and a ledge holding a piece of chalk. And above the area was a huge brass cylinder; toward this brass cylinder the professor would soon direct his subsequent remarks.

In order to assure himself that it was time to press the button which would notify the members of the class in history to approach their local Visaphones, the professor withdrew from his vest pocket a small contrivance which he held to his ear. Upon moving a tiny switch attached to the instrument, a metallic voice, seeming to come from somewhere in space, repeated mechanically: “Fifteen o’clock and one minute--fifteen o’clock and one minute--fifteen o’clock and one min--” Quickly, the professor replaced the instrument in his vest pocket and pressed a button at the side of the Visaphone.

As though in answer to the summons, the frosted squares began, one by one, to show the faces and shoulders of a peculiar type of young men; young men with great bulging foreheads, bald, toothless, and wearing immense horn spectacles. One square, however, still remained empty. On noticing this, a look of irritation passed over the professor’s countenance.

But, seeing that every other glass square but this one was filled up, he commenced to talk.

“I am pleased, gentlemen, to see you all posted at your local Visaphones this afternoon. I have prepared my lecture today upon a subject which is, perhaps, of more economic interest than historical. Unlike the previous lectures, my talk will not confine itself to the happenings of a few years, but will gradually embrace the course of ten centuries, the ten centuries, in fact, which terminated three hundred years before the present date. My lecture will be an exposition of the effects of the John Jones Dollar, originally deposited in the dawn of civilization, or to be more precise, in the year of 1921--just thirteen hundred years ago. This John Jon--”

At this point in the professor’s lecture, the frosted glass square which hitherto had shown no image, now filled up. Sternly he gazed at the head and shoulders that had just appeared.

“B262H72476Male, you are late to class again. What excuse have you to offer today?”

From the hollow cylinder emanated a shrill voice, while the lips of the picture on the glass square moved in unison with the words:

“Professor, you will perceive by consulting your class book, that I have recently taken up my residence near the North Pole. For some reason, wireless communication between the Central Energy Station and all points north of 89 degrees was cut off a while ago, on account of which fact I could not appear in the Visaphone. Hence--”

“Enough, sir,” roared the professor. “Always ready with an excuse, B262H72476Male. I shall immediately investigate your tale.”

From his coat pocket, the professor withdrew an instrument which, although supplied with an earpiece and a mouthpiece, had no wires whatever attached. Raising it to his lips, he spoke:

“Hello. Central Energy Station, please.” A pause ensued. “Central Energy Station? This is the professor of history at the University of Terra, speaking. One of my students informs me that the North Pole region was out of communication with the Visaphone System this morning. Is that statement true? I would--”

A voice, apparently from nowhere, spoke into the professor’s ear. “Quite true, Professor. A train of our ether waves accidently fell into parallelism with a train of waves from the Venus Substation. By the most peculiar mischance, the two trains happened to be displaced, with reference to each other, one half of a wave length, with the unfortunate result that the negative points of one coincided with the positive points of maximum amplitude of the other. Hence the two wave trains nullified each other and communication ceased for one hundred and eighty-five seconds--until the earth had revolved far enough to throw them out of parallelism.”

“Ah! Thank you,” replied the professor. He dropped his instrument into his coat pocket and gazed in the direction of the glass square whose image had so aroused his ire. “I apologize, B262H72476Male, for my suspicions as to your veracity--but I had in mind several former experiences.” He shook a warning forefinger. “I will now resume my talk.”

“A moment ago, gentlemen, I mentioned the John Jones Dollar. Some of you who have just enrolled with the class will undoubtedly say to yourselves: ‘What is a John Jones? What is a Dollar?’

“In the early days, before the present scientific registration of human beings was instituted by the National Eugenics Society, man went around under a crude multi-reduplicative system of nomenclature. Under this system there were actually more John Joneses than there are calories in a British Thermal Unit. But there was one John Jones, in particular, living in the twentieth century, to whom I shall refer in my lecture. Not much is known of his personal life except that he was an ardent socialist--a bitter enemy, in fact, of the private ownership of wealth.

“Now as to the Dollar. At this day, when the Psycho-Erg, a combination of the Psych, the unit of esthetic satisfaction, and the Erg, the unit of mechanical energy, is recognized as the true unit of value, it seems difficult to believe that in the twentieth century and for more than ten centuries thereafter, the Dollar, a metallic circular disk, was being passed from hand to hand in exchange for the essentials of life.

“But nevertheless, such was the case. Man exchanged his mental or physical energy for these Dollars. He then re-exchanged the Dollars for sustenance, raiment, pleasure, and operations for the removal of the vermiform appendix.

“A great many individuals, however, deposited their Dollars in a stronghold called a bank. These banks invested the Dollars in loans and commercial enterprises, with the result that, every time the earth traversed the solar ecliptic, the banks compelled each borrower to repay, or to acknowledge as due, the original loan, plus six one-hundredths of that loan. And to the depositor, the banks paid three one-hundredths of the deposited Dollars for the use of the disks. This was known as three percent, or bank interest.

“Now, the safety of Dollars, when deposited in banks, was not absolutely assured to the depositor. At times, the custodians of these Dollars were wont to appropriate them and proceed to portions of the earth, sparsely inhabited and accessible with difficulty. And at other times, nomadic groups known as ‘yeggmen’ visited the banks, opened the vaults by force, and departed, carrying with them the contents.

“But to return to our subject. In the year 1921, one of these numerous John Joneses performed an apparently inconsequential action which caused the name of John Jones to go down in history. What did he do?

“He proceeded to one of these banks, known at that time as ‘The First National Bank of Chicago,’ and deposited there, one of these disks--a silver Dollar--to the credit of a certain individual. And this individual to whose credit the Dollar was deposited was no other person than the fortieth descendant of John Jones who stipulated in paper which was placed in the files of the bank, that the descendancy was to take place along the oldest child of each of the generations which would constitute his posterity.

“The bank accepted the Dollar under that understanding, together with another condition imposed by this John Jones, namely, that the interest was to be compounded annually. That meant that at the close of each year, the bank was to credit the account of John Jones’s fortieth descendant with three one-hundredths of the account as it stood at the beginning of the year.

“History tells us little more concerning this John Jones--only that he died in the year 1931, or ten years afterward, leaving several children.

“Now you gentlemen who are taking mathematics under Professor L127M72421Male, of the University of Mars, will remember that where any number such as X, in passing through a progressive cycle of change, grows at the end of that cycle by a proportion p, then the value of the original X, after n cycles, becomes X(1 + p)^n.

“Obviously, in this case, X equalled one Dollar; p equalled three one-hundredths; and n will depend upon any number of years which we care to consider, following the date of deposit. By a simple calculation, those of you who are today mentally alert can check up the results that I shall set forth in my lecture.

“At the time that John Jones died, the amount in the First National Bank of Chicago to the credit of John Jones the fortieth, was as follows.”

The professor seized the chalk and wrote rapidly upon the oblong space:

1931 10 years elapsed $1.34

“The peculiar sinuous hieroglyphic,” he explained, “is an ideograph representing the Dollar.

“Well, gentlemen, time went on as time will, until a hundred years had passed by. The First National Bank still existed, and the locality, Chicago, had become the largest center of population upon the earth. Through the investments which had taken place, and the yearly compounding of interest, the status of John Jones’s deposit was now as follows.” He wrote:

2021 100 years elapsed $19.10

“In the following century, many minor changes, of course, took place in man’s mode of living; but the so-called socialists still agitated widely for the cessation of private ownership of wealth; the First National Bank still accepted Dollars for safe keeping, and the John Jones Dollar still continued to grow. With about thirty-four generations yet to come, the account now stood:

2121 200 years elapsed $364

“And by the end of the succeeding hundred years, it had grown to what constituted an appreciable bit of exchange value in those days--thus:

2221 300 years $6,920

“Now the century which followed contains an important date. The date I am referring to is the year 2299 A.D., or the year in which every human being born upon the globe was registered under a numerical name at the central bureau of the National Eugenics Society. In our future lessons which will treat with that period of detail, I shall ask you to memorize that date.

“The socialists still agitated, fruitlessly, but the First National Bank of Chicago was now the first International Bank of the Earth. And how great had John Jones’s Dollar grown? Let us examine the account, both on that important historical date, and also at the close of the 400th year since it was deposited. Look:

2299 378 years $68,900

2321 400 years $132,000

“But gentlemen, it had not reached the point where it could be termed an unusually large accumulation of wealth. For larger accumulations existed upon the earth. A descendant of a man once known as John D. Rockefeller possessed an accumulation of great size, but which, as a matter of fact, was rapidly dwindling as it passed from generation to generation. So, let us travel ahead another one hundred years. During this time, as we learn from our historical and political archives, the socialists began to die out, since they at last realized the utter futility of combating the balance of power. The account, though, now stood:
