ABSTRACT
The centre of the system was the self-sufficient family group, organised to satisfy its own needs in almost every respect. The elementary agricultural methods produced barely sufficient for the family group itself. Outside the area of the tsetse-fly the main task was the care of the cattle, and the diet was derived in large measure from the herds. Adequate as was this simple organisation so long as the country was isolated, so soon as contacts with the outside world increased its weaknesses began to be manifested. The groups for which payments must balance need not be purely geographical groups. They may equally be social groups or groups based on any common bond. Thus in order that Government expenditure on education may be increased there must be, directly or indirectly, a countervailing increase in the payments of taxpayers to those performing the tasks of education.
