Arthur Young's studies and writings and travels over a long life (i 741-1820) bring us into touch with almost every economic activity characteristic of the eighteenth century. We are introduced to the French economists devoted to Agriculture, the demographers like Süssmilch absorbed in vital statistics, the rising English political economy, with Cantillon, Adam Smith, Steuart, James Anderson, and Malthus as its prophets. Arthur Young and Malthus, late in the period, exchanged letters on Population and agriculture.1
