be employed in bringing them thither, together with its ordinary profits. If the ordinary price is more than this, the surplus part of it will naturally go to the rent of the land. If it is not more, though the commodity may be brought to market, it can afford no rent to the landlord. Whether the price is, or is not more, depends upon the demand.
There are some parts of the produce of land, for which the demand must always be such as to afford a greater price than what is sufficient to bring them to market, and there are others for which it either may or may not be such as to afford this greater price. The former must always afford a rent to the landlord. The latter sometimes may and sometimes may not, according to different circumstances.
Rent, it is to be observed, therefore, enters into the composition of the price of commodities in a different way from wages and profit. High or low wages and profit are the causes of high or low price; high or low rent is the effect of it. It is because high or low wages and profit must be paid, in order to bring a particular commodity to market, that its price is high or low. But it is because its price is high or low, a great deal more, or very little more, or no more, than what is sufficient to pay those wages and profit, that it affords a high rent, or a low rent, or no rent at all.
The particular consideration, first, of those parts of the produce of land which always afford some rent; secondly, of those which sometimes may and sometimes may not afford rent; and, thirdly, of the variations which, in the different periods of improvement, naturally take place in the relative value of those two different sorts of rude produce, when compared both with one another and with manufactured commodities, will divide this chapter into three parts.
Part I.—Of the Produce of Land which always affords Rent.
As men, like all other animals, naturally multiply in proportion to the means of their subsistence, food is always more or less in demand. It can always purchase or command a greater or smaller quantity of labour, and somebody can always be found who is willing to do something in order to obtain it. The quantity of labour, indeed, which it can purchase, is not always equal to what it could maintain, if managed in the most economical manner, on account of the high wages which are sometimes given to labour; but it can always purchase such a quantity of labour as it can maintain, according to the rate at which that sort of labour is commonly maintained in the neighbourhood.
But land, in almost any situation, produces a greater quantity of food than what is sufficient to maintain all the labour necessary for bringing it to market, in the most liberal way in which that labour is ever maintained. The surplus, too, is always more than sufficient to replace the stock which employed that labour, together with its profit. Something, therefore, always remains for a rent to the landlord.
The most desert moors in Norway and Scotland produce some sort of pasture for cattle, of which the milk and the increase are always more than sufficient, not only to maintain all the labour necessary for tending them, and to pay the ordinary profit to the farmer or the owner of the herd or flock, but to afford some small rent to the landlord. The rent increases in proportion to the goodness of the pasture. The same extent of ground not only maintains a greater number of cattle, but as they are brought within a smaller compass, less labour becomes requisite to tend them, and to collect their produce. The landlord gains both ways; by the increase of the produce, and by the diminution of the labour which must be maintained out of it.
The rent of land not only varies with its fertility, whatever be its produce, but with its situation, whatever be its fertility. Land in the neighbourhood of a town gives a greater rent than land equally fertile in a distant part of the country. Though it may cost no more labour to cultivate the one than the other, it must always cost more to bring the produce of the distant land to market. A greater quantity of labour, therefore, must be maintained out of it; and the surplus, from which are drawn both the profit of the farmer and the rent of the landlord, must be diminished. But in remote parts of the country, the rate of profit, as has already been shewn, is generally higher than in the neighbourhood of a large town. A smaller proportion of this diminished surplus, therefore, must belong to the landlord.
Good roads, canals, and navigable rivers, by diminishing the expense of carriage, put the remote parts of the country more nearly upon a level with those in the neighbourhood of the town. They are upon that account the greatest of all improvements. They encourage the cultivation of the remote, which must always be the most extensive circle of the country. They are advantageous to the town by breaking down the monopoly of the country in its neighbourhood. They are advantageous even to that part of the country. Though they introduce some rival commodities into the old market, they open many new markets to its produce. Monopoly, besides, is a great enemy to good management, which can never be universally established, but in consequence of that free and universal competition which forces every body to have recourse to it for the sake of self-defence. It is not more than fifty years ago, that some of the counties in the neighbourhood of London petitioned the parliament against the extension of the turnpike roads into the remoter counties. Those remoter counties, they pretended, from the cheapness of labour, would be able to sell their grass and corn cheaper in the London market than themselves, and would thereby reduce their rents, and ruin their cultivation. Their rents, however, have risen, and their cultivation has been improved since that time.
A corn field of moderate fertility produces a much greater quantity of food for man, than the best pasture of equal extent. Though its cultivation requires much more labour, yet the surplus which remains after replacing the seed and maintaining all that labour, is likewise much greater. If a pound of butcher's meat, therefore, was never supposed to be worth more than a pound of bread, this greater surplus would everywhere be of greater value and constitute a greater fund, both for the profit of the farmer and the rent of the landlord. It seems to have done so universally in the rude beginnings of agriculture.
But the relative values of those two different species of food, bread and butcher's meat, are very different in the different periods of agriculture. In its rude beginnings, the unimproved wilds, which then occupy the far greater part of the country, are all abandoned to cattle. There is more butcher's meat than bread; and bread, therefore, is the food for which there is the greatest competition, and and which consequently brings the greatest price. At Buenos Ayres, we are told by Ulloa, four reals, one-and-twenty pence halfpenny sterling, was, forty or fifty years ago, the ordinary price of an ox, chosen from a herd of two or three hundred. He says nothing of the price of bread, probably because he found nothing remarkable about it. An ox there, he says, costs little more than the labour of catching him. But corn can nowhere be raised without a great deal of labour; and in a country which lies upon the river Plate, at that time the direct road from Europe to the silver mines of Potosi, the money-price of labour could be very cheap. It is otherwise when cultivation is extended over the greater part of the country. There is then more bread than butcher's meat. The competition changes its direction, and the price of butcher's meat becomes greater than the price of bread.
By the extension, besides, of cultivation, the unimproved wilds become insufficient to supply the demand for butcher's meat. A great part of the cultivated lands must be employed in rearing and fattening cattle; of which the price, therefore, must be sufficient to pay, not only the labour necessary for tending them, but the rent, which the landlord, and the profit which the farmer, could have drawn from such land employed in tillage. The cattle bred upon the most uncultivated moors, when brought to the same market, are, in proportion to their weight or goodness, sold at the same price as these which are reared upon the most improved land. The proprietors of those moors profit by it, and raise the rent of their land in proportion to the price of their cattle. It is not more than a century ago, that in many parts of the Highlands of Scotland, butcher's meat was as cheap or cheaper than even bread made of oatmeal. The Union opened the market of England to the Highland cattle. Their ordinary price, at present, is about three times greater than at the beginning of the century, and the rents of many Highland estates have been tripled and quadrupled in the same time. In almost every part of Great Britain, a pound of the best butcher's meat is, in the present times generally worth more than two pounds of the best white bread; and in plentiful years it is sometimes worth three or four pounds.
It is thus that, in the progress of improvement, the rent and profit of unimproved pasture come to
