 The missionary Bruce Olson relates in his book, "Bruchko", that he began living with the Bari in 1962, and he says that he became the "blood brother" of a chieftain's son.According to Olson, he is part of what he refers to as the "Motilone Miracle", which involves indigenously run schools, literacy programs, medical clinics, as well as an effort of the Motilone Bari to introduce Christianity to surrounding tribes.Since the initial contact in 1650, Bari land has been reduced to 7% of its original mass and the Bari have shifted their production to the gardening of cash crops in order to acquire Western goods which are becoming increasingly integrated into their culture.
