In the most improved societies, however, there are always a few commodities of which the price resolves itself into two parts only: the wages of labour, and the profits of stock; and a still smaller number, in which it consists altogether in the wages of labour. In the price of sea-fish, for example, one part pays the labour of the fisherman, and the other the profits of the capital employed in the fishery. Rent very seldom makes any part of it, though it does sometimes, as I shall shew hereafter. It is otherwise, at least through the greater part of Europe, in river fisheries. A salmon fishery pays a rent; and rent, though it cannot well be called the rent of land, makes a part of the price of a salmon, as well as wares and profit. In some parts of Scotland, a few poor people make a trade of gathering, along the sea-shore, those little variegated stones commonly known by the name of Scotch pebbles. The price which is paid to them by the stone-cutter, is altogether the wages of their labour; neither rent nor profit makes any part of it. But the whole price of any commodity must still finally resolve itself into some one or other or all of those three parts; as whatever part of it remains after paying the rent of the land, and the price of the whole labour employed in raising, manufacturing, and bringing it to market, must necessarily be profit to somebody. As the price or exchangeable value of every particular commodity, taken separately, resolves itself into some one or other, or all of those three parts; so that of all the commodities which compose the whole annual produce of the labour of every country, taken complexly, must resolve itself into the same three parts, and be parcelled out among different inhabitants of the country, either as the wages of their labour, the profits of their stock, or the rent of their land. The whole of what is annually either collected or produced by the labour of every society, or, what comes to the same thing, the whole price of it, is in this manner originally distributed among some of its different members. Wages, profit, and rent, are the three original sources of all revenue, as well as of all exchangeable value. All other revenue is ultimately derived from some one or other of these.
