in addition to government officers, other outsiders began to enter fore territory. anthropologists ronald and catherine berndt spent time with the north fore in 1953, while missionaries and traders penetrated further south. the fore underwent considerable cultural change as a result of this contact: they traded with the outsiders, began growing coffee, and started to adopt a money-based economy. gordon t. linsley, a patrol officer stationed at okapa, noted the rapid pace of social change among the fore in a 1951 report. he observed that village warfare had declined considerably, the young fore men seemingly glad to have an excuse to quit fighting. the region was already under the control of the australian government and some villages were relocating from the high ridges down to their gardens. rest houses were present in the larger villages and separate men's houses remained only in the more isolated villages. many people regularly used the 'rough track' to travel to kainantu and were able to see the latest fashions and hear pidgin spoken. broad paths linked communities together; however, linsley noted inter-district fighting persisted and accusations of sorcery were still common in purosa.
