The combined action of these manifold and diverse forces generates a special and very important effect. It imprints on the hire of land a distinct and unique feature of its own; it imparts its peculiar characteristic to rent. The position of the farmer is not that of a man engaged in a business, and buying or hiring a machine which is required for carrying it on; it is rather the situation of one who is examining whether he can reasonably enter upon the business at all. One feeling governs that situation; the tenant must be able to live by it by means of a natural profit after all expenses have been repaid. Thus, the payment for the use of the land takes the form of handing over to the landowner all excess of profit above the fitting reward for the farmer. This seems manifestly the best method for giving the required security to the tenant, whilst it provides the lender of the use of the land a reward just in itself and compatible with the continuous cultivation of the soil. Such a system is not unacceptable to the landlord; he cannot hope to maintain a fixed rent which the returns yielded by the agricultural business do not furnish. To insist upon such a condition would be simply to compel the farmer to renounce the farm. And he will not obtain such a rent from any other tenant; for the one he dismisses has no other motive for leaving except the fact that the farm will not provide such a rent. On the other hand, if he is dissatisfied with the rent offered by the tenant, he has in the competition of tenants desirous of hiring the farm a sure test for ascertaining whether the offer is just or deficient.
