Thus, then, finally, the nature of the store has to be considered under two main lights, the one, that of its immediate and actual utility; the other, that of the past national character which it signifies by its production, and future character which it must develop by its uses. And the issue of this investigation will be to show us that Economy does not depend merely on principles of "demand and supply," but primarily on what is demanded, and what is supplied. Question Second. What is the quantity of the store in relation to the population? It follows from what has been already stated that the accurate form in which this question has to be put is--"What quantity of each article composing the store exists in proportion to the real need for it by the population?" But we shall for the time assume, in order to keep all our terms at the simplest, that the store is wholly composed of useful articles, and accurately proportioned to the several needs of them. Now it does not follow, because the store is large in proportion to the number of people, that the people must be in comfort, nor because it is small, that they must be in distress. An active and economical race always produces more than it requires, and lives (if it is permitted to do so) in competence on the produce of its daily labour. The quantity of its store, great or small, is therefore in many respects indifferent to it, and cannot be inferred by its aspect. Similarly an inactive and wasteful population, which cannot live by its daily labour, but is dependent, partly or wholly, on consumption of its store, may be (by various difficulties hereafter to be examined, in realization of getting at such store) retained in a state of abject distress, though its possessions may be immense. But the results always involved in the magnitude of store are, the commercial power of the nation, its security, and its mental character. Its commercial power, in that according to the quantity of its store, may be the extent of its dealings; its security, in that according to the quantity of its store are its means of sudden exertion or sustained endurance; and its character, in that certain conditions of civilization cannot be attained without permanent and continually accumulating store, of great intrinsic value, and of peculiar nature. Now, seeing that these three advantages arise from largeness of store in proportion to population, the question arises immediately, "Given the store--is the nation enriched by diminution of its numbers? Are a successful national speculation and a pestilence, economically the same thing?"
