There are mores corresponding to each of the great stages of the industrial organization — hunting, herding, and agricultural. When two groups which are on different stages are neighbors, or when one part of a group advances to another stage, while the remainder still practices the old form, conflicts arise. The Indian and Iranian branches of the Aryans separated under intense enmity and mutual contempt when the Iranians became tillers. All the ways of one people which conform to its industrial pursuits are an abomination to the other. The best explanation yet suggested of the statements of Cæsar and Tacitus about the Germans is that the Germans were, at that period, between nomadism and settled agriculture. There is a deep contrast of mores between town and country, agriculture on the one side and manufactures, commerce, banking, etc., on the other, and this contrast may, at any time, rise to an antagonism. The antagonism is kept down if the two classes meet often; it is developed if they become strictly separated. The town looks upon the country as rustic and uncultivated; the country looks upon the town as vicious and corrupt. The industrial interests of the two are antagonistic, and one may be subjected to the other, as is always the case under a protective tariff, for the protective system never can do anything but make the stronger form of industry carry the weaker. It is a characteristic of our time that in all civilized countries the population is moving from the country to the towns. This movement is not due to the same forces in all countries. Wherever agriculture is burdened by taxes to favor manufacturing, the legislation causes, or intensifies, the movement. It is not probable that the love of luxury, excitement, social intercourse, and amusement is any greater now than it always has been, but
