We have just proved that, if the farm-rent in a community of one thousand laborers is one hundred, that of nine hundred would be ninety, that of eight hundred, eighty, that of one hundred, ten, &c. So that, in a community where there was but one laborer, the farm-rent would be but 0.1; no matter how great the extent and value of the land appropriated. Therefore, WITH A GIVEN LANDED CAPITAL, PRODUCTION IS PROPORTIONAL TO LABOR, NOT TO PROPERTY. Guided by this principle, let us try to ascertain the maximum increase of all property whatever. What is, essentially, a farm-lease? It is a contract by which the proprietor yields to a tenant possession of his land, in consideration of a portion of that which it yields him, the proprietor. If, in consequence of an increase in his household, the tenant becomes ten times as strong as the proprietor, he will produce ten times as much. Would the proprietor in such a case be justified in raising the farm-rent tenfold? His right is not, The more you produce, the more I demand. It is, The more I sacrifice, the more I demand. The increase in the tenant's household, the number of hands at his disposal, the resources of his industry,--all these serve to increase production, but bear no relation to the proprietor. His claims are to be measured by his own productive capacity, not that of others. Property is the right of increase, not a poll-tax. How could a man, hardly capable of cultivating even a few acres by himself, demand of a community, on the ground of its use of ten thousand acres of his property, ten thousand times as much as he is incapable of producing from one acre? Why should the price of a loan be governed by the skill and strength of the borrower, rather than by the utility sacrificed by the proprietor? We must recognize, then, this second economical law: INCREASE IS MEASURED BY A FRACTION OF THE PROPRIETORS PRODUCTION. Now, this production, what is it? In other words, What can the lord and master of a piece of land justly claim to have sacrificed in lending it to a tenant? The productive capacity of a proprietor, like that of any laborer, being one, the product which he sacrifices in surrendering his land is also one. If, then, the rate of increase is ten per cent., the maximum increase is 0.1. But we have seen that, whenever a proprietor withdraws from production, the amount of products is lessened by 1. Then the increase which accrues to him, being equal to 0.1 while he remains among the laborers, will be equal after his withdrawal, by the law of the decrease of farm-rent, to 0.09. Thus we are led to this final formula: THE MAXIMUM INCOME OF A PROPRIETOR IS EQUAL TO THE SQUARE ROOT OF THE PRODUCT OF ONE LABORER (some number being agreed upon to express this product). THE DIMINUTION WHICH THIS INCOME SUFFERS, IF THE PROPRIETOR IS IDLE, IS EQUAL TO A FRACTION WHOSE NUMERATOR IS 1, AND WHOSE DENOMINATOR IS THE NUMBER WHICH EXPRESSES THE PRODUCT.
