 The expense of maintaining the fixed capital in a great country, may very properly be compared to that of repairs in a private estate. The expense of repairs may frequently be necessary for supporting the produce of the estate, and consequently both the gross and the net rent of the landlord. When by a more proper direction, however, it can be diminished without occasioning any diminution of produce, the gross rent remains at least the same as before, and the net rent is necessarily augmented.

But though the whole expense of maintaining the fixed capital is thus necessarily excluded from the net revenue of the society, it is not the same case with that of maintaining the circulating capital. Of the four parts of which this latter capital is composed, money, provisions, materials, and finished work, the last three, it has already been observed, are regularly withdrawn from it, and placed either in the fixed capital of the society, or in their stock reserved for immediate consumption. Whatever portion of those consumable goods is not employed in maintaining the former, goes all to the latter, and makes a part of the net revenue of the society. The maintenance of those three parts of the circulating capital, therefore, withdraws no portion of the annual produce from the net revenue of the society, besides what is necessary for maintaining the fixed capital.

The circulating capital of a society is in this respect different from that of an individual. That of an individual is totally excluded from making any part of his net revenue, which must consist altogether in his profits. But though the circulating capital of every individual makes a part of that of the society to which he belongs, it is not upon that account totally excluded
