ABSTRACT
In general, the difference in the means by which food is obtained has largely contributed to a difference in the mutual estimation and the behaviour of the groups coming into ethnical contact. This close association, when the groups are sharply divided from each other, tends to stratification in which the herdsmen have the advantage, as has been already explained. Overwhelming individual influence as an institution was not possible in a homogeneous democratic society as, e. g., among predatory tribes. But by the fact that the heads of families repartitioned the captives of war and the agricultural communities among each other, they became recognized and institutional leaders of other people. Trading goes on briskly among the various tribes in the Ovambo country. Traders intending to exploit certain areas find it most profitable to direct their operations to peoples of widely different race and culture.
