THE GEOMETRICIAN.—Why, if they produce each twenty-five livres, (about twenty English shillings), it is a great deal; but not to discourage our countrymen, let us put them at thirty livres. There are acres which produce constantly regenerating value, and which are estimated at three hundred livres: there are others which only produce three livres. The mean proportion between three and three hundred is thirty; for you must allow that three is to thirty as thirty is to three hundred. If, indeed, there were comparatively many acres at thirty livres, and very few at three hundred, our account would not hold good; but, once more, I would not be over punctilious.
THE MAN OF FORTY CROWNS.—Well, sir; how much will these fourscore millions of acres yield of revenue, estimated in money?
THE GEOMETRICIAN.—The account is ready made; they will produce two thousand four hundred millions of livres of the present currency.
THE MAN OF FORTY CROWNS.—I have read that Solomon possessed, of his own property, twenty-five thousand millions of livres, in ready money; and certainly there are not two thousand four hundred millions of specie circulating in France, which, I am told, is much greater and much richer than Solomon's country.
THE GEOMETRICIAN.—There lies the mystery. There may be about nine hundred millions circulating throughout the kingdom; and this money, passing from hand to hand, is sufficient to pay for all the produce of the land, and of industry. The same crown may pass ten times from the pocket of the cultivator, into that of the ale-housekeeper, and of the tax-gatherer.
THE MAN OF FORTY CROWNS.—I apprehend you. But you told me that we are, in all, about twenty millions of inhabitants, men, women, old and young. How much, pray, do you allow for each?
THE GEOMETRICIAN.—One hundred and twenty livres, or forty crowns.
THE MAN OF FORTY CROWNS.—You have just guessed my revenue. I have four acres, which, reckoning the fallow years with those of produce, bring me in one hundred and twenty livres; which is little enough, God knows.
But if every individual were to have his contingent, would that be no more than five louis d'ors a year?
THE GEOMETRICIAN.—Certainly not, according to our calculation, which I have a little amplified. Such is the state of human nature. Our life and our fortune have narrow limits. In Paris, they do not, one with another, live above twenty-two or twenty-three years, and, one with another, have not, at the most, above a hundred and twenty livres a year to spend. So that your food, your raiment, your lodging, your movables, are all represented by the sum of one hundred and twenty livres.
