BOOK 1
Chapter 1 of the division of labour
The nature of agriculture, indeed, does not admit of so many subdivisions of labour, nor of so complete a separation of one business from another, as manufactures. It is impossible to separate so entirely, the business of the grazier from that of corn-farmer as the trade of the carpenter is commonly separated from that of the smith.
More opulent nations are generally more distinguished by their manufecturing industry. (rather than farming. farming is in general more productive but not as much as manufacturing.)
In other words, in agriculture the labour of rich country is not always much more productive than poor country.
The corn of Poland, in the same degree of goodness, is as cheap as that of France, notwitstanding the superior opulence and improvement of the latter country.
