It is not, however, so much from the low price of corn, as from that of some other parts of the rude produce of land, that the most judicious writers have inferred the great value of silver in those very ancient times. Corn, it has been said, being a sort of manufacture, was, in those rude ages, much dearer in proportion than the greater part of other commodities; it is meant, I suppose, than the greater part of unmanufactured commodities, such as cattle, poultry, game of all kinds, &c. That in those times of poverty and barbarism these were proportionably much cheaper than corn, is undoubtedly true. But this cheapness was not the effect of the high value of silver, but of the low value of those commodities. It was not because silver would in such time purchase or represent a greater quantity of labour, but because such commodities would purchase or represent a much smaller quantity than in times of more opulence and improvement. Silver must certainly be cheaper in Spanish America than in Europe; in the country where it is produced, than in the country to which it is brought, at the expense of a long carriage both by land and by sea, of a freight, and an insurance. One-and-twenty pence halfpenny sterling, however, we are told by Ulloa, was, not many years ago, at Buenos Ayres, the price of an ox chosen from a herd of three or four hundred. Sixteen shillings sterling, we are told by Mr Byron, was the price of a good horse in the capital of Chili. In a country naturally fertile, but of which the far greater part is altogether uncultivated, cattle, poultry, game of all kinds, &c. as they can be acquired with a very small quantity of labour, so they will purchase or command but a very small quantity. The low money price for which they may be sold, is no proof that the real value of silver is there very high, but that the real value of those commodities is very low. Labour, it must always be remembered, and not any particular commodity, or set of commodities, is the real measure of the value both of silver and of all other commodities. But in countries almost waste, or but thinly inhabited, cattle, poultry, game of all kinds, &c. as they are the spontaneous productions of Nature, so she frequently produces them in much greater quantities than the consumption of the inhabitants requires. In such a state of things, the supply commonly exceeds the demand. In different states of society, in different states of improvement, therefore, such commodities will represent, or be equivalent, to very different quantities of labour.
