Secondly, of all those profitable buildings which are the means of procuring a revenue, not only to their proprietor who lets them for a rent, but to the person who possesses them and pays that rent for them; such as shops, warehouses, workhouses, farmhouses, with all their necessary buildings; stables, granaries, etc. These are very different from mere dwelling houses. They are a sort of instruments of trade, and may be considered in the same light:

Thirdly, of the improvements of land, of what has been profitably laid out in clearing, draining, enclosing, manuring, and reducing it into the condition most proper for tillage and culture. An improved farm may very justly be regarded in the same light as those useful machines which facilitate and abridge labour, and by means of which an equal circulating capital can afford a much greater revenue to its employer. An improved farm is equally advantageous and more durable than any of those machines, frequently requiring no other repairs than the most profitable application of the farmer's capital employed in cultivating it:

Fourthly, of the acquired and useful abilities of all the inhabitants or members of the society. The acquisition of such talents, by the maintenance of the acquirer during his education, study, or apprenticeship, always costs a real expense, which is a capital fixed and realized, as it were, in his person. Those talents, as they make a part of his fortune, so do they likewise of that of the society to which he belongs. The improved dexterity of a workman may be considered in the same light as a machine or instrument of trade which facilitates and abridges labour, and which, though it costs a certain expense, repays that expense with a profit.

The third and last of the three portions into which the general stock of the society naturally divides itself, is the circulating capital; of which the characteristic is, that it affords a revenue only by circulating or changing masters. It is composed likewise of four parts:

First, of the money by means of which all the other three are circulated and distributed to their proper consumers:

Secondly, of the stock of provisions which are in the possession of the butcher, the grazier, the farmer, the corn-merchant, the brewer, etc., and from the sale of which they expect to derive a profit:

Thirdly, of the materials, whether altogether rude, or more or less manufactured, of clothes, furniture, and building, which are not yet made up into any of those three shapes, but which remain in the hands of the growers, the manufacturers, the mercers and drapers, the timber merchants, the carpenters and joiners, the brickmakers, etc.

Fourthly, and lastly, of the work which is made up and completed, but which is still in the hands of the merchant or manufacturer, and not yet disposed of or distributed to the proper consumers; such as the finished work which we frequently find ready-made in the shops of the smith, the cabinet-maker, the goldsmith, the jeweller, the china-merchant, etc. The circulating capital consists in this manner, of the provisions, materials, and finished work of all kinds that are in the hands of their respective dealers, and of the money that is necessary for circulating and distributing them to those who are finally to use or to consume them.

Of these four parts, three- provisions, materials, and finished work- are, either annually, or in a longer or shorter period, regularly withdrawn from it, and placed either in the fixed capital or in the stock reserved for immediate consumption.

Every fixed capital is both originally derived from, and requires to be continually supported by a circulating capital. All useful machines and instruments of trade are originally derived from a circulating capital, which furnishes the materials of which they are made, and the maintenance of the workmen who make them. They require, too, a capital of the same kind to keep them in constant repair.
