Adam Smith, in his observations on colonial trade, has shewn, most satisfactorily, the advantages of a free trade, and the injustice suffered by colonies, in being prevented by their mother countries, from selling their produce at the dearest market, and buying their manufactures and stores at the cheapest. He has shewn, that by permitting every country freely to exchange the produce of its industry when and where it pleases, the best distribution of the labour of the world will be effected, and the greatest abundance of the necessaries and enjoyments of human life will be secured.
