Wednesday, September 7, 1938. Fine, though cloudy, for an hour or so after daylight, then rain most of day. Little work done in camp. Our #1 cook, Amat, too stiff to-work after the unaccustomed hard excursion of yesterday and the day before. Left two boys to start preparations for drying plants, and with one boy collected along the base of the cliffs S-SW of camp, and from there up the side of the spur to the summit through wet and mossy low forest clinging to the steep slopes. For some distance I followed up the narrow bed of a stream, walking on a thick mattress of moss and small shrubs (Vaccinium), and although the stream wound underfoot, for the whole distance I saw no water. So far as I have seen, the low, broken forests are composed chiefly of Vaccinium 9690 (one of the major forest species of Habbema) and a small leaved Eurya () not yet seen in flower or fruit. Thursday, September 8, 1938. Bright clear morning: fine view of the main ridge leading to the summit of Mt. Wilhelmina. The E. tip of which is just visible from our tents. A good frost on the grass in camp. Ground frightfully wet and squishing underfoot. Archbold, Teerink and Toxopeus with two boys and an escort of four soldiers, made a trip beyond the lake and picked a subsidiary camp site on the ridge above, at about 3800 m. altitude. A party of Dyak and Convict carriers arrived with supplies and returned for Tuschen Camp during the morning.
