and all the party flown to the Idenburg or Hollandia. Itinerary. Bernhard Camp, Idenburg River, to camp 18 Km. N.W., altitude 2150 meters. The members of the inland collecting party spent Christmas and New Years at Hollandia. By January 3rd all of the inland party was at Bernhard Camp with about two and a half months supply of food. Van Arcken had already established a track to the highest available point within reasonable reach of Bernhard Camp (2150 meter camp, two and a half days journey) and had prepared camp sites at the altitude we planned to work. We worked the higher camps first, and thus inspected the lower camp sites on the way up. On January 6 we, van Arcken, Brass, Rand, Richardson and Toxopeus, passed the 950 meter camp site and moved to the 1250 meter camp, and spent the night at this site, from which we later collected, and continued to the 1800 meter camp on the 7th. As the 2150 meter site was only two hours beyond, and being on top of a spur with a small area of high country, we worked from the 1800 meter camp first. Transports were continually going between this camp and Bernhard Camp, and van Arcken, Huls and Teerink made many trips back and forth to prepare camp sites, arrange transport and for inspection. January 10 Toxopeus went up to the 2150 meter camp 18 km. S.W. of Bernhard Camp, to collect there until the rest of us moved up. Van Arcken had already prepared this site and provisioned it. About January 30 Toxopeus returned to the 1800 meter camp, moved down to a subsidiary camp at 1650 meters, an hour or so down the ridge. Toxopeus was the only collector to occupy this camp, though bird and mammal collecting boys were sent there with him. Toxopeus occupied
