It is essential that the investigators observe the area under varying circumstances: labor in the fields, meetings of a local association (noting the behavior of the participants, the language used, and the relations between the officers and the members), the role played by women and by young people, leisure hours, games and sports, conversations with people in their homes (noting examples of husband-wife and parent-child relationships). No activity must escape the attention of the investigators during the initial survey of the area.
