tion. Agriculture furnished not alone grain, peas, beans and fruit, but also oil and wine, the preparation of which had now been learned. Such a diversity of action could not be displayed by any single individual. The second great division of labor took place: handicrafts separatea from agriculture. The growing intensity of production and the increased productivity enhanced the value of human labor power. Slavery, which had been a rising and sporadic factor in the preceding stage, now became an essential part of the social system. The slaves ceased to be simple assistants. They were now driven in scores to the work in the fields and shops. The division of production into two great branches, agriculture and handicrafts, gave rise to production for exchange, the production of commodities. Trade arose at the same time, not only in the interior and on the tribal boundaries, but also in the form of maritime exchange. All this was as yet in a very undeveloped state. The precious metals gained preference as a universal money commodity, but still uncoined and exchanged merely by dead weight.
The distinction between rich and poor was added to that between free men and slaves. This and the new division or labor constitute a new division of society into classes. The differences in the amount of property belonging to the several family heads broke up the old communistic households one by one, wherever they might have been preserved thus far. This made an end to the collective cultivation of the soil for the account of the community. The cultivated land was assigned for use to the several families, first tor a limited time, later for once and all. The transition to full private property was accomplished gradually and simultaneously with the transition from, the pairing family to monogamy.
