to such a price as would remunerate the expense of producing it from a certain quality of soil, it happened nevertheless that all the soil of that quality was withheld from cultivation, by the obstinacy of the owners in demanding a rent for it, not nominal, nor trifling, but sufficiently onerous to be a material item in the calculations of a farmer. What would then happen? Merely that the increase of produce, which the wants of society required, would for the time be obtained wholly (as it always is partially), not by an extension of cultivation, but by an increased application of labour and capital to land already cultivated.

Now we have already seen that this increased application of capital, other things being unaltered, is always attended with a smaller proportional return. We are not to suppose some new agricultural invention made precisely at this juncture; nor a sudden extension of agricultural skill and knowledge, bringing into more general practice, just then, inventions already in partial use. We are to suppose no change, except a demand for more corn, and a consequent rise of its price. The rise of price enables measures to be taken for increasing the produce, which could not have been taken with profit at the previous price. The farmer uses more expensive manures; or manures land which he formerly left to nature; or procures lime or marl from a distance, as a dressing for the soil; or pulverizes or weeds it more thoroughly; or drains, irrigates, or subsoils portions of it which at former prices would not have paid the cost of the operation; and so forth. These things, or some of them, are done, when, more food being wanted, cultivation has no means of expanding itself upon new lands. And when the impulse is given to extract an increased amount of produce from the soil, the farmer or improver will only consider whether the outlay he makes for the purpose will be returned to him with the ordinary profit, and not whether any surplus will remain for rent. Even, therefore, if it were the fact that there is never any land taken into cultivation, for which rent, and that too of an

amount worth taking into consideration, was not paid; it would be true nevertheless that there is always some agricultural capital which pays no rent, because it returns nothing beyond the ordinary rate of profit: this capital being the portion of capital last applied-that to which the last addition to the produce was due; or (to express the essentials of the case in one phrase), that which is applied in the least favourable circumstances. But the same amount of demand, and the same price, which enable this least productive portion of capital barely to replace itself with the ordinary profit, enable every other portion to yield a surplus, proportioned to the advantage it possesses. And this surplus it is, which competition enables the landlord to appropriate. The rent of all land is measured by the excess of the return to the whole capital employed on it, above what is necessary to replace the capital with the ordinary rate of profit, or in other words, above what the same capital would yield if it were all employed in as disadvantageous circumstances as the least productive portion of it: whether that least productive portion of capital is rendered so by being employed on the worst soil, or by being expended in extorting more produce from land which already yielded as much as it could be made to part with on easy terms.

It is not pretended that the facts of any concrete case conform with absolute precision to this or any other scientific principle. We must never forget that the truths of political economy are truths only in the rough. It is not, for example, strictly true that a farmer will cultivate no land, and apply no capital, which returns less than the ordinary profits. He will expect the ordinary profits on the bulk of his capital. But when he has cast in his lot with his farm, and bartered his skill and exertions, once for all, against what the farm will yield to him, he will probably be willing to expend capital on it (for an immediate return) in any manner which will afford him a surplus profit however small, beyond the value

of the risk, and the interest which he must pay for the capital if borrowed, or can get for it elsewhere if it is his own. But a new farmer, entering on the land, would make his calculations differently, and would not commence unless he could expect the full rate of ordinary profit on all the capital which he intended embarking in the enterprize. Again, prices may range higher or lower during the currency of a lease, than was expected when the contract was made, and the land, therefore, may be over or under-rented: and even when the lease expires, the landlord may be unwilling to grant a necessary diminution of rent, and the farmer, rather than relinquish his occupation, or seek a farm elsewhere when all are occupied, may consent to go on paying too high a rent. Irregularities like these we must always expect: it is impossible in political economy to obtain general theorems embracing the complications of circumstances which may affect the result in an individual case. The laws which we are enabled to lay down respecting rents, profits, wages, prices, are only true in so far as the persons concerned are free from the influence of any other motives than those arising from the general circumstances of the case, and are guided, as to those, by the ordinary mercantile estimate of profit and loss. Applying this twofold supposition to the case of farmers and landlords, it will be true that the farmer requires the ordinary rate of profit on the whole of his capital; that whatever it returns to him beyond this he is obliged to pay to the landlord, but will not consent to pay more; that there is a portion of capital applied to agriculture in such circumstances of productiveness as to yield only the ordinary profits; and that the difference between the produce of this, and of any other capital of similar amount, is the measure of the tribute which that other capital can and will pay, under the name of rent, to the landlord. This constitutes a law of rent, as near the truth as such a law can possibly be: though of course modified or disturbed in individual cases, by pending

contracts, individual miscalculations, the influence of habit, and even the particular feelings and dispositions of the persons concerned.

§ 5. A remark is often made, which must not here be omitted, although, I think, more importance has been attached to it than it merits. Under the name of rent, many payments are commonly included, which are not a remuneration for the original powers of the land itself, but for capital expended on it. The additional rent which land yields in consequence of this outlay of capital, should, in the opinion of some writers, be regarded as profit, not rent. But before this can be admitted, a distinction must be made. The annual payment by a tenant almost always includes a consideration for the use of the buildings on the farm; not only barns, stables, and other outhouses, but a house to live in, not to speak of fences and the like. The landlord will ask, and the tenant give, for these, whatever is considered sufficient to yield the ordinary profit, or rather (risk and trouble being here out of the question) the ordinary interest, on the value of the buildings; that is, on what it has cost to erect them, or rather, on what it would now cost to erect others as good: the tenant being bound, in addition, to leave them in as good repair as he found them, for otherwise a much larger payment than simple interest would of course be required from him. These buildings are as distinct a thing from the farm, as the stock or the timber on it; and what is paid for them can no more be called rent of land, than a payment for cattle would be, if it were the custom that the landlord should stock the farm for the tenant. The buildings, like the cattle, are not land, but capital, regularly consumed and reproduced; and all payments made in consideration for them are properly interest.

But with regard to capital actually sunk in improvements, and not requiring periodical renewal, but spent once for all in giving the land a permanent increase of productive

ness, it appears to me that the return made to such capital loses altogether the character of profits, and is governed by the principles of rent. It is true that a landlord will not expend capital in improving his estate unless he expects from the improvement an increase of income, surpassing the interest of his outlay. Prospectively, this increase of income may be regarded as profit; but when the expense has been incurred, and the improvement made, the rent of the improved land is governed by the same rules as that of the unimproved. Equally fertile land commands an equal rent, whether its fertility is natural or acquired; and I cannot think that the incomes of those who own the Bedford Level or the Lincolnshire Wolds, ought to be called profit and not rent because those lands would have been worth next to nothing unless capital had been expended on them. The owners are not capitalists, but landlords; they have parted with their capital; it is consumed, destroyed; and neither is, nor is to be, returned to them, like the capital of a farmer or manufacturer, from what it produces. In lieu of it they now have land, of a certain richness, which yields the same rent, and by the operation of the same causes, as if it had possessed from the beginning the degree of fertility which has been artificially given to it.

An American political economist of merit, Mr. H. C. Carey, takes away, still more completely than I have attempted to do, the distinction between these two sources of rent, by rejecting one of them altogether: he considers all rent as the effect of capital expended. In proof of this, he contends that the whole pecuniary value of all the land in any country, in England for instance, or in the United States, does not amount to anything approaching to the sum which has been laid out, or which it would even now be necessary to lay out, in order to bring the country to its pre
