lower rent-such improvements enable rent, in the progress of society, to rise gradually to a much higher limit than it could otherwise attain, since they enable a much lower quality of land to be ultimately cultivated. But in the case we are now supposing, which nearly corresponds to the usual course of things, this ultimate effect becomes the immediate effect. Suppose cultivation to have reached, or almost reached, the utmost limit permitted by the state of the industrial arts, and rent, therefore, to have attained nearly the highest point to which it can be carried by the progress of population and capital, with the existing amount of skill and knowledge. If a great agricultural improvement were suddenly introduced, it might throw back rent for a considerable space, leaving it to regain its lost ground by the progress of population and capital, and afterwards to go on further. But, taking place, as such improvement always does, very gradually, it causes no retrograde movement of either rent or cultivation; it merely enables the one to go on rising, and the other extending, long after they must otherwise have stopped. It would do this even without the necessity of resorting to a worse quality of land; simply by enabling the lands already in cultivation to yield a greater produce, with no increase of the proportional cost. If by improvements of agriculture all the lands in cultivation could be made, even with double labour and capital, to yield a double produce, (supposing that in the meantime population increased so as to require this double quantity,) all rents would be doubled.

To illustrate the point, let us revert to the numerical example in a former page. Three qualities of land yield respectively 100, 80, and 60 bushels to the same outlay on the same extent of surface. If No. 1 could be made to yield 200, No. 2, 160, and No. 3, 120 bushels, at only double the expense, and therefore without any increase of the cost of production, and if the population, having doubled, required all this increased quantity, the rent of No. 1 would be 80 bushels instead of 40, and of No. 2, 40 instead of 20, while

the price and value per bushel would be the same as before: so that corn rent and money rent would both be doubled. I need not point out the difference between this result, and what we have shown would take place if there were an improvement in production without the accompaniment of an increased demand for food.

Agricultural improvement, then, is always ultimately, and in the manner in which it generally takes place also immediately, beneficial to the landlord. We may add, that when it takes place in that manner, it is beneficial to no one else. When the demand for produce fully keeps pace with the increased capacity of production, food is not cheapened; the labourers are hot, even temporarily, benefited; the cost of labour is not diminished, nor profits raised. There is a greater aggregate production, a greater produce divided among the labourers, and a larger gross profit; but the wages being shared among a larger population, and the profit spread over a larger capital, no labourer is better off, nor does any capitalist derive from the same amount of capital a larger income.

The result of this long investigation may be summed up as follows. The economical progress of a society constituted` of landlords, capitalists, and labourers, tends to the progressive enrichment of the landlord class; while the cost of the labourer's subsistence tends on the whole to increase, and profits to fall. Agricultural improvements are a counteracting force to the two last effects; but the first, though a case is conceivable in which it would be temporarily checked, is ultimately in a high degree promoted by those improvements; and the increase of population tends to transfer all the benefits derived from agricultural improve ment to the landlords alone. What other consequences, in addition to these, or in modification of them, arise from the industrial progress of a society thus constituted, I shall endeavour to show in the succeeding chapter.

CHAPTER IV.

OF THE TENDENCY OF PROFITS TO A MINIMUM.

§ 1. THE tendency of profits to fall as society advances, which has been brought to notice in the preceding chapter, was early recognised by writers on industry and commerce; but the laws which govern profits not being then understood, the phenomenon was ascribed to a wrong cause. Adam Smith considered profits to be determined by what he called the competition of capital; and concluded that when capital increased, this competition must likewise increase, and profits must fall. It is not quite certain what sort of competition Adam Smith had here in view. His words in the chapter on Profits of Stock* are, "When the stocks of many rich merchants are turned into the same trade, their mutual competition naturally tends to lower its profits; and when there is a like increase of stock in all the different trades carried on in the same society, the same competition must produce the same effect in them all." This passage would lead us to infer that, in Adam Smith's opinion, the manner in which the competition of capital lowers profits is by lowering prices; that being usually the mode in which an increased investment of capital in any particular trade, lowers the profits of that trade. But if this was his meaning, he overlooked the circumstance, that the fall of price, which if confined to one commodity really does lower the profits of the producer, ceases to have that effect as soon as it extends to all commodities; because, when all things

* Wealth of Nations, book i. chap. 9.

have fallen, nothing has really fallen, except nominally; and even computed in money, the expenses of every producer have diminished as much as his returns. Unless indeed labour be the one commodity which has not fallen in money price, when all other things have: if so, what has really taken place is a rise of wages; and it is that, and not the fall of prices, which has lowered the profits of capital. There is another thing which escaped the notice of Adam Sinith; that the supposed universal fall of prices, through increased competition of capitals, is a thing which cannot take place. Prices are not determined by the competition of the sellers only, but also by that of the buyers; by demand as well as supply. The demand which affects money prices consists of all the money in the hands of the community destined to be laid out in commodities; and as long as the proportion of this to the commodities is not diminished, there is no fall of general prices. Now, howsoever capital may increase, and give rise to an increased production of commodities, a full share of the capital will be drawn to the business of producing or importing money, and the quantity of money will be augmented in an equal ratio with the quantity of commodities. For if this were not the case, and if money, therefore, were, as the theory supposes, perpetually acquiring increased purchasing power, those who produced or imported it would obtain constantly increasing profits; and this could not happen without attracting labour and capital to that occupation from other employments. If a general fall of prices, and increased value of money, were really to occur, it could only be as a consequence of increased cost of production, from the gradual exhaustion of the mines.

It is not tenable, therefore, in theory, that the increase of capital produces, or tends to produce, a general decline of money prices. Neither is it true, that any general decline of prices, as capital increased, has manifested itself in fact. The only things observed to fall in price with the progress of society, are those in which there have been

improvements in production, greater than have taken place in the production of the precious metals; as for example, all spun and woven fabrics. Other things again, instead of falling, have risen in price, because their cost of production, compared with that of gold and silver, has increased. Among these are all kinds of food, comparison being made with a much earlier period of history. The doctrine, therefore, that competition of capital lowers profits by lowering prices, is incorrect in fact, as well as unsound in principle.

But it is not certain that Adam Smith really held that doctrine; for his language on the subject is wavering and unsteady, denoting the absence of a definite and well-digested opinion. Occasionally he seems to think that the mode in which the competition of capital lowers profits, is by raising wages. And when speaking of the rate of profit in new colonies, he seems on the very verge of grasping the complete theory of the subject. "As the colony increases, the profits of stock gradually diminish. When the most fertile and best situated lands have been all occupied, less profit can be made by the cultivation of what is inferior both in soil and situation." Had Adam Smith meditated longer on the subject, and systematized his view of it by harmonizing with each other the various glimpses which he caught of it from different points, he would have perceived that this last is the true cause of the fall of profits usually consequent upon increase of capital.

§ 2. Mr. Wakefield, in his Commentary on Adam Smith, and his important writings on Colonization, takes a much clearer view of the subject, and arrives, through a substantially correct series of deductions, at practical conclusions which appear to me just and important; but he is not equally happy in incorporating his valuable speculations with the results of previous thought, and reconciling them with other truths. Some of the theories of Dr. Chalmers, in his chapter "On the Increase and Limits of Capital," and the two chapters which follow it, coincide in their tendency
