Related to the above was the delivery of public lectures to the Indians in the course of which the anthropologist explained that he had been invited by the Mennonites to help find the best ways of assisting the Indians to become "people." An appeal was then made to all individuals having knowledge of things that the anthropologist should know to draw such matters to the latter's attention. This approach was very productive in locating tension spots that were developing in the relationship between the Indians and the Mennonite cultures. It was after one such lecture that a Chulup Indian asked the anthropologist why it was that the church-going whites generally sat down one meter away from the Indians, while those people who did not go to church and did not believe in God often wanted to sit down beside the Indians and drink yerba mate [an herbal tea] with them.
