Take two tracts of equal extent, one of which brings in five and the other ten. If the inhabitants of the first consume four and those of the second nine, the surplus of the first product will be a fifth and that of the second a tenth. The ratio of these two surpluses will then be inverse to that of the products, and the tract which produces only five will give a surplus double that of the tract which produces ten. But there is no question of a double product, and I think no one would put the fertility of cold countries, as a general rule, on an equality with that of hot ones. Let us, however, suppose this equality to exist: let us, if you will, regard England as on the same level as Sicily, and Poland as Egypt--further south, we shall have Africa and the Indies; further north, nothing at all. To get this equality of product, what a difference there must be in tillage: in Sicily, there is only need to scratch the ground; in England, how men must toil! But, where more hands are needed to get the same product, the superfluity must necessarily be less. Consider, besides, that the same number of men consume much less in hot countries. The climate requires sobriety for the sake of health; and Europeans who try to live there as they would at home all perish of dysentery and indigestion. "We are," says Chardin, "carnivorous animals, wolves, in comparison with the Asiatics. Some attribute the sobriety of the Persians to the fact that their country is less cultivated; but it is my belief that their country abounds less in commodities because the inhabitants need less. If their frugality," he goes on, "were the effect of the nakedness of the land, only the poor would eat little; but everybody does so. Again, less or more would be eaten in various provinces, according to the land's fertility; but the same sobriety is found throughout the kingdom. They are very proud of their manner of life, saying that you have only to look at their hue to recognise how far it excels that of the Christians. In fact, the Persians are of an even hue; their skins are fair, fine and smooth; while the hue of their subjects, the Armenians, who live after the European fashion, is rough and blotchy, and their bodies are gross and unwieldy." The nearer you get to the equator, the less people live on. Meat they hardly touch; rice, maize, curcur, millet and cassava are their ordinary food. There are in the Indies millions of men whose subsistence does not cost a halfpenny a day. Even in Europe we find considerable differences of appetite between Northern and Southern peoples. A Spaniard will live for a week on a German's dinner. In the countries in which men are more voracious, luxury therefore turns in the direction of consumption. In England, luxury appears in a well-filled table; in Italy, you feast on sugar and flowers.
