151 Saturday, January 7, 1939. Left camp at 6.40 AM - behind the main body of carriers - and reached the 1800 m. camp at 3.45 PM. A long hard day with much climbing and de- scending in mist and intermittent light rain. Followed ridge crests: the mossy forests dripping moisture and the track slushy and in places very steep. My legs showed signs of giving out in the last 1/2 hour. Van Arcken has made a good job of track-cutting and has established good camps in localities suitable for collecting, i. e. 1170 and 1800 m. A third collecting camp will be established on dry ground somewhere near van Arcken's old camp on the flood plain of Araucaria Creek. For details of Bernhard Camp -- 1800 m. camp trip, see field notebook #3. Sunday, January 8, 1939. Mist and rain all day. Part of day spent in preparations about camp and the remainder in rest. Camp is situated in tall mossy forest on the crest of a spur rising direct from the plains of the Idenburg. According to van Arcken it is about 15 km. NW of Bernhard Camp. Monday, January 9, 1939. Day broke clear after a sharp shower preceding the dawn: fine to 11.20, when mist cleared down--or rather was driven up from the Idenburg: a shower at 12.30: afternoon fine, with intermittent mist: clear starry evening. Good views of Idenburg winding through plains. A good morning in the field, on the crest of the ridge beyond camp. 45 spp. catalogued and have perhaps 20 more on hand. Radio news to the effect that at Bernhard Camp on the Idenburg, the flood continues to rise - the only building not flooded being the dining room.
