A particular country, in the same manner as a particular person, may frequently not have capital sufficient both to improve and cultivate all its lands, to manufacture and prepare their whole rude produce for immediate use and consumption, and to transport the surplus part either of the rude or manufactured produce to those distant markets, where it can be exchanged for something for which there is a demand at home. The inhabitants of many different parts of Great Britain have not capital sufficient to improve and cultivate all their lands. The wool of the southern counties of Scotland is, a great part of it, after a long land carriage through very bad roads, manufactured in Yorkshire, for want of a capital to manufacture it at home. There are many little manufacturing towns in Great Britain, of which the inhabitants have not capital sufficient to transport the produce of their own industry to those distant markets where there is demand and consumption for it. If there are any merchants among them, they are, properly, only the agents of wealthier merchants who reside in some of the great commercial cities.
When the capital of any country is not sufficient for all those three purposes, in proportion as a greater share of it is employed in agriculture, the greater will be the quantity of productive labour which it puts into motion within the country; as will likewise be the value which its employment adds to the annual produce of the land and labour of the society. After agriculture, the capital employed in manufactures puts into motion the greatest quantity of productive labour, and adds the greatest value to the annual produce. That which is employed in the trade of exportation has the least effect of any of the three.
The country, indeed, which has not capital sufficient for all those three purposes, has not arrived at that degree of opulence for which it seems naturally destined. To attempt, however, prematurely, and with an
