ABSTRACT
A distinction is made in every tribe between its own members and visitors or other aliens. Membership of a tribe, as previously noted, is defined, not in terms of birth, but of allegiance to the Chief. It is possible for people not born into a tribe to become subjects of its Chief, either by conquest or by placing themselves voluntarily under his rule. If the man's application is favourably received, he may sometimes be tested for about a year or so before being finally admitted into membership of the tribe. A group of foreigners wishing to join the tribe must in the same way obtain permission from the Chief. Immigrant communities consist as a rule of people who have broken away from their parent tribe owing to some political dispute. Every member of a tribe is also permitted to move about freely in the tribal territory, unless he is, for political reasons, confined by the Chief to a particular district.
