It is equally clear, that if the necessaries of life the most important products of land--had not the property of creating an increase of demand proportioned to their increased quantity, such increased quantity would occasion a fall in their exchangeable value. However abundant might be the produce of a country, its population might remain stationary And this abundance, without a proportionate demand, and with a very high corn price of labour, which would naturally take place under these circumstances, might reduce the price of raw produce, like the price of manufactures, to the cost of production. It has been sometimes argued, that it is mistaking the principle of population, to imagine, that the increase of food, or of raw produce alone, can occasion a proportionate increase of population. This is no doubt true; but it must be allowed, as has been justly observed by Adam Smith, that 'when food is provided, it is comparatively easy to find the necessary clothing and lodging. And it should always be recollected, that land does not produce one commodity alone, but in addition to that most indispensable of all commodities--food--it produces also the materials for the other necessaries of life; and the labour required to work up these materials is of course never excluded from the consideration. [6] It is, therefore, strictly true, that land produces the necessaries of life, produces food, materials, and labour, produces the means by which, and by which alone, an increase of people may be brought into being, and supported. In this respect it is fundamentally different from every other kind of machine known to man; and it is natural to suppose, that it should be attended with some peculiar effects. If the cotton machinery, in this country, were to go on increasing at its present rate, or even much faster; but instead of producing one particular sort of substance which may be used for some parts of dress and furniture, etc. had the qualities of land, and could yield what, with the assistance of a little labour, economy, and skill, could furnish food, clothing, and lodging, in such proportions as to create an increase of population equal to the increased supply of these necessaries; the demand for the products of such improved machinery would continue in excess above the cost of production, and this excess would no longer exclusively belong to the machinery of the land.
