David Ricardo：On the Principles of Political Economy and Taxation, Excerpt 184

We have already shewn how the capital of a country is either fixed or circulating, according as it is of a more or of a less durable nature. It is difficult to define strictly, where the distinction between circulating and fixed capital begins; for there are almost infinite degrees in the durability of capital. The food of a country is consumed and reproduced, at least once in every year; the clothing of the labourer is probably not consumed and reproduced in less than two years; whilst his house and furniture are calculated to endure for a period of ten or twenty years.
