this camp until February 2. The 2150 meter camp was occupied by the rest of the collecting party until February 10, when it was evacuated. The night was spent at the 1800 meter camp. February 11 we moved to the 1650 meter camp, a one-night camp of van Arcken, on the route where Brass spent two nights and Rand one night before going down to the 1200 meter camp. Richardson went straight down to the 1200 meter camp. Brass moved down to the 850 meter camp on March 4. Again this camp had been prepared for us by Teerink and van Arcken. Richardson moved down on March 6 and Rand on March 7. Since very high water was reported on the Idenburg, Rand spent March 18-27 at Bernhard Camp to investigate the bird life under these conditions. Brass moved from the 850 meter camp to Bernhard Camp April 6, Richardson and Rand April 8. Richardson and Brass occupied a sub- sidiary camp a half hour from Bernhard Camp and about 25 meters higher, at the base of the hills, until April 18 (Brass) and 24 (Richardson). Rand went directly to the main camp and worked from there. On the 8th, 9th and 10th the camp was evacuated and the whole campy flown to Hollandia.
