he was away. On September 11 Rand moved up to the 3800 meter camp which Archbold and Teerink had already established. Collecting boys were again left to continue work at the 3600 meter camp. The period September 20-28 Rand, in company with Archbold, Schreuder and Teerink, spent in two small camps at 4000 meters, one to the south and one to the west of the peak, and reached an altitude of 4500 meters about 1/3 of a kilometer west of the summit. Bad weather prevailed and most of this time was spent in idleness. On our return to the 3800 meter camp September 28 it was decided to abandon the idea of climb- ing the peak of Mt. Wilhelmina. During this period boys were col- lecting birds at both the 3600 and 3800 meter camps. We started to evacuate the 3800 meter camp September 29 and by October 2 the whole party was back at Habbema Lake. October 3 - October 7 was spent collecting the group material for the bird habitat group. The 2800 meter camp had been examined by Toxopeus and by van Arcken, was established by Brass on October 8, and Rand started col- lecting there October 10 and continued until November 10, when he moved down to the 2200 meter camp. This camp site had been chosen by Brass and Teerink on an exploratory trip, October 25-28, of the Bele River valley, and established October 31 by Huls and Teerink. Bird collecting was carried on here until October 4. When Rand went up to Habbema November 14 to see to loading group material, the col- lecting boys were left at work at the 2200 meter camp. When Rand returned on November 18 and 19, Habbema Camp was definitely abandon- ed, as Huls and Teerink had already established a camp on the Balim River where the plane landed and deposited reserve food. December 5, 6 and 7 Brass, Rand, Richardson, Teerink and Toxopeus moved to the 1600 meter camp on the Balim River, where collecting was carried on until December 18. On December 18 and 19 this camp was abandoned
