Elements of Political Economy by James Mill (1844)
We have seen that two classes of persons are concerned in production; Labourers, and Capitalists. Each of these classes must have its share of the commodities produced: or, which comes to the same thing, of the benefit derived from them. When the Land is one of the instruments of production, another party comes in for a portion; I mean, the Owners of the Land. And these three classes; the labourers, the capitalists, and the landlords; immediately share, that is, divide among them, the whole of the annual produce of the country.
When the parties are determined, among whom the whole of the produce is distributed, it remains to be ascertained, by what laws the proportions are established, according to which the division is made. We shall begin with the explanation of Rent, or the share received by Landlords; as it is the most simple, and will facilitate the explanation of the laws, upon which the shares, of the Labourers, and of the Capitalists, depend.
Land is of different degrees of fertility. There is a species of land, the elevated or stony parts, for example, of high mountains, loose sand, and certain marshes, which may be said to produce nothing. Between this and the most productive sort, there are lands of all the intermediate degrees of fertility.
Again; lands, of the highest fertility, do not yield the whole of what they are capable of yielding, with the same facility. A piece of land, for example, may be capable of yielding annually ten quarters of corn, or twice ten, or three times ten, It yields, however, the first ten, with a certain quantity of labour, the second ten, not without a greater, the third ten, not without a greater still, and so on; every additional ten requiring to its production a greater cost than the ten which preceded it. This is well known to be the law, according to which, by a greater expenditure of capital, a greater produce is obtained, from the same portion of land.
Till the whole of the best land is brought under cultivation, and till it has received the application of a certain quantity of capital, all the capital employed upon the land is employed with an equal return. At a certain point, however, no additional capital can be employed upon the same land, without a diminution of return. In any country, therefore, after a certain quantity of corn has been raised, no greater quantity can be raised, but at a greater cost. If such additional quantity is raised, the capital, employed upon the land, may be distinguished into, two portions; one, producing a higher; another, a lower return.
When capital producing a lower return is applied to the land, it is applied in one of two ways. It is either applied to new land of the second degree of fertility, then for the first time brought under cultivation; or it is applied to land of the first degree of fertility, which has already received all the capital which can be applied without a diminution of return.
Whether capital shall be applied to land of the second degree of fertility, or in a second dose to the land of the first degree of fertility, will depend, in each instance, upon the nature and qualities of the two soils. If the same capital which will produce only eight quarters, when applied in a second dose to the best land, will produce nine quarters, when applied to land of the second degree of fertility, it will be applied to that land, and vice versa
The land of the different degrees of fertility; first, or highest sort; second, or next highest, and so on, may, for facility of reference, be denominated, No. 1, No. 2, No. 3, &c. In like manner, the different doses of capital, which may be applied to the same land, one after another, with less and less effect, may be denominated 1st dose, 2d dose, 3d dose, and so on.
So long as land produces nothing, it is not worth appropriating. So long as a part only of the best land is required for cultivation, all that is uncultivated yields nothing; that is, nothing which has any value. It naturally, therefore, remains unappropriated; and any man may have it, who undertakes to render it productive.
During this time, land, speaking correctly, yields no rent. There is a difference, no doubt, between the land which has been cultivated, and the land which is yet uncleared for cultivation. Rather than clear the fresh land, a man will pay an equivalent, annual, or otherwise, for the cost of clearing: and it is evident that he will pay no more. This, therefore, is not a payment for the power of the soil, but simply for the capital bestowed upon the soil. It is not rent; it is interest.
The time, however, arrives, as population, and the demand for food increase, when it is necessary either to have recourse to land of the second quality, or to apply a second dose of capital, less productively, upon land of the first quality.
If a man cultivates land of the second quality; upon which a certain quantity of capital will produce only eight quarters of corn, while the same quantity of capital upon land of the first quality will produce ten quarters; it will make no difference to him, whether he pay two quarters for leave to cultivate the first sort, or cultivate the second without any payment. He will therefore be content to pay two quarters for leave to cultivate the first sort; and that payment constitutes rent.
Let us suppose, again, that instead of cultivating land of the second quality, it is more advisable to apply a second dose of capital to land of the first quality; and that, while the first dose produces ten quarters, the second, of equal amount, will produce only eight quarters; it is equally implied in this, as ill the former case, that it is impossible to employ any more capital with so great an effect as the ten supposed quarters, and that there are persons who are willing to apply it with so little a return as eight. But if there are persons who are willing to apply their capital on the land with so little a return as eight quarters, the owners of the land may make a bargain, by which they will obtain all that is produced above eight. The effect upon rent is thus the same in both cases.
It follows that rent increases in proportion as the productive power of the capital, successively bestowed upon the land, decreases. If population has arrived at another stage, when, all the land of second quality being cultivated, it is necessary to have recourse to land of third quality, yielding, instead of eight quarters, only six, it is evident, from the same process of reasoning that the land of second quality will now yield rent, namely, two quarters; and that land of first quality will yield an augmented rent, namely, two quarters more. The case will be exactly the same, if, instead of having recourse to land of less fertility, a second and a third dose of capital, with the same diminution of produce, are bestowed upon land of the first quality.
We may thus obtain a general expression for rent. In applying capital, either to lands of various degrees of fertility, or, in successive doses, to the same land, some portions of the capital so employed are attended with a greater produce, some with a less. That which yields the least, yields all that is necessary for reimbursing and rewarding the capitalist. The capitalist will receive no more than this remuneration for any portion of the capital which he employs, because the competition of others will prevent him. All that is yielded above this remuneration, the landlord will be able to appropriate. Rent, therefore, is the difference between the return made to the more productive portions, and that which is made to the least productive portion, of capital, employed upon the land.
Taking, for illustration, the three cases, Of ten quarters, eight quarters, and six quarters, we perceive, that rent is the difference between six quarters and eight quarters for the portion of capital which yields only eight quarters; the difference between six quarters and ten quarters for the portion of capital which yields ten quarters; and if three doses of capital, one yielding ten, another eight, and another six quarters, are applied to the same portion of land, its rent will be four quarters for dose No. 1, and two quarters for dose No. 2, making together six quarters for the whole.
If these conclusions are well supported, the doctrine of rent is simple, and the consequences, as we shall see hereafter, are exceedingly important. There is but one objection, which it seems possible to make to them. It may be said, that, after land is appropriated, there is no portion of it which does not pay rent, no owner being disposed to give the use of it for nothing. This objection has, indeed, been raised; and it has been urged, that some rent is paid even for the most barren of the Scottish mountains.
If an objection is taken, it affects the conclusion, either to a material, or to an immaterial extent.. Where the matter alleged in objection, even if admitted, would still leave the conclusion substantially, and to all practical purposes, true, the objection must be owing to one of two defects in the mind of the objector; either a confusion of ideas, which prevents him from seeing to how small a degree the matter which he alleges affects the doctrine which he denies; or a disposition to evade the admission of the doctrine, even though nothing solid can be found with which to oppose it.
That the matter alledged in this objection, even if allowed, would leave the conclusion, to all practical purposes, just where it was, can hardly fail to be acknowledged, as soon as the circumstances are disclosed. It cannot be so much as pretended that the rent paid for the barren mountains of Scotland is any thing but a trifle; an evanescent quantity, when we speak of any moderate extent. If it were 5 l. for a thousand acres, that is, about one penny per acre, it would bear so small a proportion to the cost of cultivation, which could not be less than several pounds per acre, that it would little affect the truth of the conclusion we have endeavoured to establish.
Let us suppose, for the sake of the argument, that the worst species of land under cultivation pays one penny per acre: rent, in that case, would be the difference between the produce resulting from different portions of capital, as explained above, with the correction required on account of the penny per acre paid as rent for the worst species of land under cultivation. Assuredly, if right in every other respect, we shall not be far wrong in our conclusions, by leaving this penny out of the question. A very slight advantage, in simplifying our language on the subject, would justify this omission.
But it is not true, that our conclusions stand in need of any such correction, even for metaphysical exactness. There is land, such as the sands of Arabia, which yields nothing. Land is found at all the intermediate stages from this to the highest fertility. Some land, though not absolutely incapable of yielding any thing for the accommodation of man, could not be made to yield what would maintain the labourers required for its cultivation. This land can never be cultivated. There is land, the annual produce of which would just maintain the labour necessary for its cultivation, and no more. This land is just capable of being cultivated, but obviously incapable of paying rent. The objection, therefore, is not only practically immaterial, it is metaphysically unsound.
It may be safely affirmed, that there is no country, of any considerable extent, in which there is not land incapable of yielding rent: that is, incapable of yielding to human labour more than would be necessary for the maintenance of that labour. That such, at least, is the case in this country, seems very unlikely to be disputed. There are parts of its mountains where nothing less hardy than heath, others where nothing but moss, can vegetate. When it is asserted that every part of the mountains of Scotland pays rent, the state of the facts is misunderstood. It is only true that there is no tenant of any portion of any man's estate in the highlands of Scotland, who does not pay rent. The reason is, because even in the mountains of Scotland there are spots in the valleys, the produce of which is considerable. It does not follow, though hundreds of acres of mountain are added to these valleys, that therefore every part of the mountain yields rent; it is certain that many parts neither do nor can.
Even where the land is not absolutely barren, and where there is still something for the more hardy of the useful animals to pick up, it is not to be allowed that rent is the necessary consequence. It ought to be remembered, that these cattle are capital, and that the land must afford enough not only to make the return for that capital, but to pay for the tendance of the cattle, of which, in such situations, especially in winter, not a little is required. Unless the land yields all this, and something more, it cannot yield any rent.
In the greater part of this island, there is hardly a farm, of any considerable extent, which does not contain land, some of more, some of less fertility, varying from a high or moderate degree of fertility, down to land which yields not enough to afford any rent. Of course I do not request admission to this affirmation upon my authority; I rest it upon an appeal to the experience of those men who am best acquainted with the circumstances. If the state of the facts corresponds with the affirmation, it follows demonstratively, that the last portion of the land which is placed under cultivation yields no rent. In such farms as those we have now described, the tenant has bargained for a certain sum to the landlord. That, of course, was calculated, upon the produce of the land which yielded not only the proper return for the capital with which it was cultivated, but something more. As the motive of the tenant to cultivate is wholly constituted by the proper return to his capital, if there is any portion of the barren land, included in his farm, which will just yield the profit of stock, and no more; though it will not afford any thing for rent, it affords to him the adequate motive for cultivation. It can hardly be denied that, in the insensible degrees by which land declines from greater to less fertility, there will, in all considerable farms, be generally found a portion with this particular degree and no more.
The conclusion, however, may be established, by the clearest evidence, without regard to the question, whether all land pays or does not pay rent. On land which pays the highest rent, we have seen that capital, applied in successive doses, is not attended with equal results. The first dose yields more, possibly much more, than the return for the capital. The second also may yield more, and so on. The rent, if accurately calculated, will be equal to all that is rendered by those several doses, over and above the profits of stock. The cultivator, of course, applies all those several doses of capital on which he has agreed to pay rent. But immediately after them comes another dose, which though it yields nothing for rent, may fully yield the ordinary profits of stock. It is for the profits of stock, and them alone, that the farmer cultivates. As long, therefore, as capital applied to his farm will yield the ordinary profits of stock, he will apply capital, if he has it. I therefore conclude, with assurance, that in the natural state of things, in every agricultural country, one portion of the capital employed upon the land pays no rent; that rent, therefore, consists wholly, of that produce which is yielded by the more productive portions of capital, over and above a quantity equal to that which constitutes the return to the least productive portion, and which must be received, to afford his requisite profits, by the farmer.
