¹ Statistics of foreign trade in the eighteenth century have to be used with caution. , Arnould, La Balance du commerce (1791)Google Scholar, is the main French source. Customs prices were arbitrarily set and might, have but little relation to actual market rates. Similarly, the English customs used up to 1854 prices established in 1696; although real or declared values were introduced as an addendum. Furthermore, smuggling was important and of course escaped customs' statisticians. Finally, extreme caution must be exercised in extrapolating generalizations from global trade figures in making international comparisons of economic potential. Allowances have to be made for entrepot trade and for imports that are put through simple stages of processing before being exported. Thus, although Arnould's figures show an increase in French foreign trade over the eighteenth century, the increase after about 1766 is to be accounted for principally by sugar and coffee.

⁴ Clark, Colin, Conditions of Economic Progress (London: Macmillan and Company, 1940)Google Scholar. The rationalization for giving income per capita of the working force rather than of the total population is that there is a difference among nations of proportions of the population of working age. Thus, for example, where the average age is low, the proportion of dependent children is high. Income per capita of the total population would accordingly distort the picture of output per operative.

⁵ This confirms the judgment of Henri Sée, Französische Wirtschaftsgeschichte (Jena: Fischer, 1936), I, 465Google Scholar. Allowance for the loss of Alsace-Lorraine must be made in interpreting the national figures for 1870-1918.

²⁰ The term “exploitable natural resource” is employed in the sense of products of nature for the utilization of which man has developed a need and techniques. Thus pitchblende was not an exploitable natural resource until there was a need and known methods for the use of uranium.
