The Manufacturing Power and Commerce
We have hitherto merely spoken of the relations between agriculture and manufactures, because they form the fundamental ingredients of the national production, and because, before obtaining a clear view of their mutual relations, it is impossible to comprehend correctly the actual function and position of commerce. Commerce is also certainly productive (as the school maintains); but it is so in quite a different manner from agriculture and manufactures. These latter actually produce goods, commerce only brings about the exchange of the goods between agriculturists and manufacturers, between producers and consumers. From this it follows that commerce must be regulated according to the interests and wants of agriculture and manufactures, not vice versв.
