Portrait of Adam Smith Adam Smith,  The Wealth of Nations (1902)

“ By means of the industry of merchants, artificers, and manufacturers, the proprietors and cultivators can purchase both the foreign goods and the manufactured produce of their own country which they have occasion for with the produce of a much smaller quantity of their own labour than what they would be obliged to employ if they were to attempt, in an awkward and unskilful manner, either to import the one or to make the other for their own use. ”

Lucius Quintus Cincinnatus Lamar,  Kidd v. Pearson — Opinion of the Court

“ No distinction is more popular to the common mind, or more clearly expressed in economic and political literature, than that between manufactures and commerce. Manufacture is transformation-the fashioning of raw materials into a change of form for use. The functions of commerce are different. The buying and selling and the transportation incidental thereto constitute commerce; and the regulation of commerce in the constitutional sense embraces the regulation at least of such transportation. ”
