these cases, the increase in the price of agricultural produce, compared with the cost of the instruments of production, appears from what has been said to be only temporary; and in these instances it will often give a considerable stimulus to cultivation, by an increase of agricultural profits, without showing itself much in the shape of rent. It hardly ever fails, however, to increase rent ultimately. The increased capital, which is employed in consequence of the opportunity of making great temporary profits, can seldom if ever be entirely removed from the land, at the expiration of the current leases; and, on the renewal of these leases, the landlord feels the benefit of it in the increase of his rents.

Whenever then, by the operation of the four causes above mentioned, the difference between the price of produce and the cost of the instruments of production increases, the rents of land will rise.

It is, however, not necessary that all these four causes should operate at the same time; it is only necessary that the difference here mentioned should increase. If, for instance, the price of produce were to rise, while the wages of labour, and the price of the other branches of capital did not rise in proportion, and at the same time improved modes of agriculture were coming into general use, it is evident that this difference might be increased, although the profits of agricultural stock were not only undiminished, but were to rise decidedly higher.

Of the great additional quantity of capital employed upon the land in this country, during the last twenty years, by far the greater part is supposed to have been generated on the soil, and not to have been brought from commerce or manufactures. And it was unquestionably the high profits of agricultural stock, occasioned by improvements in the modes of agriculture, and by the constant rise of prices, followed only slowly by a proportionate rise in the different branches of capital, that afforded the means of so rapid and so advantageous an accumulation.

In this case cultivation has been extended, and rents have risen, although one of the instruments of production, capital, has been dearer.

In the same manner a fall of profits and improvements in agriculture, or even one of them separately, might raise rents, notwithstanding a rise of wages.

It may be laid down then as a general truth, that rents naturally rise as the difference between the price of produce and the cost of the instruments of production increases.

It is further evident, that no fresh land can be taken into cultivation till rents have risen, or would allow of a rise upon what is already cultivated.

Land of an inferior quality requires a great quantity of capital to make it yield a given produce; and, if the actual price of this produce be not such as fully to compensate the cost of production, including the existing rate of profits, the land must remain uncultivated. It matters not whether this compensation is effected by an increase in the money price of raw produce, without a proportionate increase in the money price of the instruments of production, or by a decrease in the price of the instruments of production, without a proportionate decrease in the price of produce. What is absolutely necessary, is a greater relative cheapness of the instruments of production, to make up for the quantity of them required to obtain a given produce from poor land.

But whenever, by the operation of one or more of the causes before mentioned, the instruments of production become cheaper, and the difference between the price of produce and the expenses of cultivation increases, rents naturally rise. It follows therefore as a direct and necessary consequence, that it can never answer to take fresh land of a poorer quality into cultivation, till rents have risen or would allow of a rise, on what is already cultivated.

It is equally true, that without the same tendency to a rise of rents, occasioned by the operation of the same causes, it cannot answer to lay out fresh capital in the improvement of old land—at least upon the supposition, that each farm is already furnished with as much capital as can be laid out to advantage, according to the actual rate of profits.

It is only necessary to state this proposition to make its truth appear. It certainly may happen, and I fear it happens frequently, that farmers are not provided with all the capital which could be employed upon their farms, at the actual rate of agricultural profits. But supposing they are so provided, it implies distinctly, that more could not be applied without loss, till, by the operation of one or more of the causes above enumerated, rents had tended to rise.

It appears then, that the power of extending cultivation and increasing produce, both by the cultivation of fresh land and the improvement of the old, depends entirely upon the existence of such prices, compared with the expense of production, as would raise rents in the actual state of cultivation.

But though cultivation cannot be extended, and the produce of the country increased, but in such a state of things as would allow of a rise of rents, yet it is of importance to remark, that this rise of rents will be by no means in proportion to the extension of cultivation, or the increase of produce. Every relative fall in the price of the instruments of production, may allow of the employment of a considerable quantity of additional capital; and when either new land is taken into cultivation, or the old improved, the increase of produce may be considerable, though the increase of rents be trifling. We see, in consequence, that in the progress of a country towards a high state of cultivation, the quantity of capital employed upon the land, and the quantity of produce yielded by it, bears a constantly increasing proportion to the amount of rents, unless counterbalanced by extraordinary improvements in the modes of cultivation. 11

According to the returns lately made to the Board of Agriculture, the average proportion which rent bears to the value of the whole produce, seems not to exceed one fifth; 12 whereas formerly, when there was less capital employed, and less value produced, the proportion amounted to one fourth, one third, or even two fifths. Still, however, the numerical difference between the price of produce and the expenses of cultivation, increases with the progress of improvement; and though the landlord has a less share of the whole produce, yet this less share, from the very great increase of the produce, yields a larger quantity, and gives him a greater command of corn and labour. If the produce of land be represented by the number six, and the landlord has one fourth of it, his share will be represented by one and a half. If the produce of land be as ten, and the landlord has one fifth of it, his share will be represented by two. In the latter case, therefore, though the proportion of the landlord's share to the whole produce is greatly diminished, his real rent, independently of nominal price, will be increased in the proportion of from three to four. And in general, in all cases of increasing produce, if the landlord's share of this produce do not diminish in the same proportion, which though it often happens during the currency of leases, rarely or never happens on the renewal of them, the real rents of land must rise.

We see then, that a progressive rise of rents seems to be necessarily connected with the progressive cultivation of new land, and the progressive improvement of the old: and that this rise is the natural and necessary consequence of the operation of four causes, which are the most certain indications of increasing prosperity and wealth—namely, the
