proverb or saying. These sayings are part of the adat in the sense that they give guidance and instruction to every member of a particular ethnic group to treat others well in the community. It is believed that pepatah were created by ancestors inspired by supernatural powers and spirits (Nasroen 1967:27). The wording of a pepatah is taken from nature, which means that all guidance for people's life must be derived from the laws of nature. Nature has its own laws and it is people's obligation to submit to it. As the myth of origin told, humans were parts of nature; they were made of it, so they had to live in total submission to its laws (Nasroen 1967:30). Here are some examples of pepatah: dalam laut dapat diduga, dalam hati siapa tahu (we can assume the depth of the sea, but we cannot assume what is in people's hearts) teaches very clearly about the danger of assuming what is in people's hearts, for this knowledge can only be obtained by asking the people concerned, not by assuming; ada gula, ada semut (where there is sugar, there is ant) teaches the law of causality, in which an effect can be inferred if there is a cause; malu bertanya, sesat di jalan (if you are shy of asking questions, you will get lost in your way) teaches the importance of asking questions in the process of seeking after knowledge, and the like. Adat Social Structure It has been stated above that not only did adat include tradition, custom, convention and law, but it also included a kind of social structure. The social structure bound by a common adat was typified by small-scale communities of people in villages or of nomads wandering over a specific area. These communities were rather like miniature democratic republics. Their headmen were elected from the descendants of the oldest branch of the tribe, and they saw to the needs and interests of the community, assisted by a council of elders. Really important decisions were taken by collective deliberations, called as mupakat. Naturally in a democracy of this type, in which a premium is put on unanimity of opinions, the position of the balai was extremely important. This was the building in which meetings and discussions were held. We can think them as the centers of social life within these small communities (Alisjahbana 1961:14-15). The principal duty of
