576 equivalent always might be, and generally is, termed rent. The question, therefore, respecting the influence which the appropriation of natural agents produces on values, is often stated in this form: Does Rent enter into Cost of Production? and the answer of the best political economists is in the negative. The temptation is strong to the adoption of these sweeping expressions, even by those who are aware of the restrictions with which they must be taken; for there is no denying that they stamp a general principle more firmly on the mind, than if it were hedged round in theory with all its practical limitations. But they also puzzle and mislead, and create an impression unfavourable to political economy, as if it disregarded the evidence of facts. No one can deny that rent sometimes enters into cost of production. If I buy or rent a piece of ground, and build a cloth manufactory on it, the ground-rent forms legitimately a part of my expenses of production, which must be repaid by the product. And since all factories are built on ground, and most of them in places where ground is peculiarly valuable, the rent paid for it must, on the average, be compensated in the values of all things made in factories. In what sense it is true that rent does not enter into the cost of production or affect the value of agricultural produce, will be shown in the succeeding chapter.
