At the time of our expedition to the Bosavi region no scientific work had been undertaken there at all.. The Kaluli and Waragu people were largely still following their traditional ways of life. A protestant missionary had built a small airstip near Didessa village; so there was easy access to this unexplored region, but he had left no other noticeable changes behind. During our one month‘ stay we had many visitors from other Bosavi villages which had not seen any white people before. Their portraits are all
included. The first contact with the Bosavi Papuans was made by Jack Hides and Jim O’Malley in 1935. A forth patrol by the Australian administration passed through the area during our stay, coming from Tari headquarters further north. The porters of this
party were wearing their fabulous wigs: so we include a selection of photographs of these Huli people as well, taken all at Didessa village. Shortly after our zoological and ethnographical field work, Edward and Bambi Schieffelin arrived for a much more detailed ethnological study. Our collections of Kaluli and Waragu material culture are now with the PNG National Museum at Port Moresby and the Wereldmuseum of Rotterdam. We attach also a few pictures taken during the ascent to the summit of Mt. Bosavi (2.896 m), an extinct volcano. For the magnificent forest of the Bosavi region we made a first national park proposal to the PNG Adminstration and conservation NGOs as early as 1970.
