ABSTRACT
The ethnographic monograph which sought only to record as historical facts the manners and customs of peculiar peoples was painstakingly elaborate in its description of technological detail. In contrast to this many of the latest anthropological works with their wholehearted sociological emphasis have ignored technological detail altogether. Social anthropologists tacitly admit the existence of some inter-relationship between the social forms of a culture and its visible material aspects, but the nature of this relationship is seldom specifically examined. The interest tends to be so exclusively on the abstract concept of social structure, that the co-existence of a formal material structure is sometimes forgotten. The indications are that land resources are for the most part as fully utilised as present technical equipment permits; the amount of marginal land that could be brought into cultivation merely by ah increase in economic inducement is small.
