 land and labor of the society. An artificer, for example, who, in the first six months after harvest, executes ten pounds' worth of work, though he should in the same time consume ten pounds' worth of corn and other necessaries, yet really adds the value of ten pounds to the annual produce of the land and labor of the society. While he has been consuming a half yearly revenue of ten pounds' worth of corn and other necessaries, he has produced an equal value of work capable of purchasing, either to himself or to some other person, an equal half yearly revenue. The value, therefore, of what has been consumed and produced during these six months is equal, not to ten but to twenty pounds. It is possible, indeed, that no more than ten pounds' worth of this value may ever have existed at any one moment of time. But if the ten pounds' worth of corn and other necessaries, which were consumed by the artificer, had been consumed by a soldier or by a menial servant, the value of that part of the annual produce which existed at the end of the six months would have been ten pounds less than it actually is in consequence of the labor of the artificer. Though the value of what the artificer produces, therefore, should not at any one moment of time be supposed greater than the value he consumes, yet at every moment of time the actually existing value of goods in the market is, in consequence of what he produces, greater than it otherwise would be.

When the patrons of this system assert, that the consumption of artificers, manufacturers and merchants is equal to the value of what they produce, they probably mean no more than that their revenue, or the fund destined for their consumption, is equal to it. But if they had expressed themselves more accurately, and only asserted that
