question there can be no doubt. It tends in a very high degree to diminish them.
In poor and backward societies, as in the East, and in Europe during the Middle Ages, extraordinary differences in the price of the same commodity might exist in places not very distant from each other, because the want of roads and canals, the imperfection of marine navigation, and the insecurity of communications generally, prevented things from being transported from the places where they were cheap to those where they were dear. The things most liable to fluctuations in value, those directly influenced by the seasons, and especially food, were seldom carried to any great distances. Each locality depended, as a general rule, on its own produce and that of its immediate neighbourhood. In most years, accordingly, there was, in some part or other of any large country, a real dearth. Almost every season must be unpropitious to some among the many soils and climates to be found in an extensive tract of country; but as the same season is also in general more than ordinarily favourable to others, it is only occasionally that the aggregate produce of the whole country is deficient, and even then in a less degree than that of many separate portions; while a deficiency at all considerable, extending to the whole world, is a thing almost unknown. In modern times, therefore, there is only dearth, where there formerly would have been famine, and sufficiency everywhere when anciently there would have been scarcity in some places and superfluity in others.
The same change has taken place with respect to all other articles of commerce. The safety and cheapness of communications, which enable a deficiency in one place to be supplied from the surplus of another, at a moderate or even a small advance on the ordinary price, render the fluctuations of prices much less extreme than formerly. This effect is much promoted by the existence of large capitals, belonging to what are called speculative merchants, whose business it is to buy goods in order to resell them at a profit.
