520 gives only the ordinary profit of capital, without leaving anything for rent; a standard is afforded for estimating the amount of rent which will be yielded by all other land. Any land yields just as much more than the ordinary profits of stock, as it yields more than what is returned by the worst land in cultivation. The surplus is what the farmer can afford to pay as rent to the landlord; and since, if he did not so pay it, he would receive more than the ordinary rate of profit, the competition of other capitalists, that competition which equalizes the profits of different capitals, will enable the landlord to appropriate it. The rent, therefore, which any land will yield, is the excess of its produce, beyond what would be returned to the same capital if employed on the worst land in cultivation. This is not, and never was pretended to be, the limit of metayer rents, or of cottier rents; but it is the limit of farmers' rents. No land rented to a capitalist farmer will permanently yield more than this; and when it yields less, it is because the landlord foregoes a part of what, if he chose, he could obtain.

This is the theory of rent, first propounded at the end of the last century by Dr. Anderson, and which, neglected at the time, was almost simultaneously rediscovered, twenty years later, by Sir Edward West, Mr. Malthus, and Mr. Ricardo. It is one of the cardinal doctrines of political economy; and until it was understood, no consistent explanation could be given of many of the more complicated industrial phenomena. The evidence of its truth will be manifested with a great increase of clearness, when we come to trace the laws of the phenomena of Value and Price. Until that is done, it is not possible to free the doctrine from every difficulty which may present itself, nor perhaps to convey, to those previously unacquainted with the subject, more than a general apprehension of the reasoning by which the theorem is arrived at. Some, however, of the objections commonly made to it, admit of a complete answer even in the present stage of our inquiries.
