profits, that of some other artificer of whom he purchases them. Part of his circulating capital is employed in purchasing materials, and replaces, with their profits, the capitals of the farmers and miners of whom he purchases them. But a great part of it is always, either annually, or in a much shorter period, distributed among the different workmen whom he employs. It augments the value of those materials by their wages, and by their masters’ profits upon the whole stock of wages, materials, and instruments of trade employed in the business. It puts immediately into motion, therefore, a much greater quantity of productive labour, and adds a much greater value to the annual produce of the land and labour of the society, than an equal capital in the hands of any wholesale merchant.
No equal capital puts into motion a greater quantity of productive labour than that of the farmer. Not only his labouring servants, but his labouring cattle, are productive labourers. In agriculture, too, Nature labours along with man; and though her labour costs no expense, its produce has its value, as well as that of the most expensive workmen. The most important operations of agriculture seem intended, not so much to increase, though they do that too, as to direct the fertility of Nature towards the production of the plants most profitable to man. A field overgrown with briars and brambles, may frequently produce as great a quantity of vegetables as the best cultivated vineyard or corn field. Planting and tillage frequently regulate more than they animate the active fertility of Nature; and after all their labour, a great part of the work always remains to be done by her. The labourers and labouring cattle, therefore, employed in agriculture, not only occasion, like the workmen in manufactures, the reproduction of a value equal to their own consumption, or to the capital which employs them, together with its owner’s profits, but of a much greater value. Over and above the capital of the farmer, and all its profits, they regularly occasion the reproduction of the rent of the landlord. This rent may be considered as the produce of those powers of Nature, the use of which the landlord
