reduction of free peasants as far down as they went towards serfdom, and we know that it was not their own energy of resistance which kept them from going lower. Furthermore, all over Europe among the peasant-tillers of the soil, while they were free yeomen (if they ever were so), there were slaves. These were owned by the freeholders. But if the yeomen were themselves slaveholders, their society is excluded from my proposition, for the society does not then consist of free and equal tillers of the soil alone.
I wish to bring into connection with this another fact which may seem at first to lie far removed from it. In stages of half-civilization where tillage is just beginning we find that the tillers are ruled by warlike nomads. This relation has been found all over the globe; especially where the tillers occupy a fertile plain below steppes or mountain slopes, the latter are inhabited by wild and wandering tribes which periodically descend into the plains to rob and plunder or levy tribute. A large part of Africa has long presented this state of things. It is evident that the settled tillers unlearn the arts of war, for they want peace, order, regularity. They must spend great labor on permanent works of construction and irrigation which are, however, at the mercy of an invader. The nomads are warlike and have greater physical power; they either make periodical raids or they compromise for a regular tribute. Great states have grown in the course of time out of this latter relation, the ruling nomads becoming the nobles and the tillers the peasantry or serfs. The first of these stages shows us militarism and industrialism in conflict; the second shows us the two combined and adjusted in a great state. This antagonism of militarism and industrialism is the most
