Wednesday, September 21, 1938. Early morning high overcast: open towards N.: mist closed over tops before seven o'clock and remained at about 4000 m. until 11 o'clock, when light rain commenced at camp level. Mist closed down on camp by noon. A bad day for the Mt. Wilhelmina party. A convoy of four Dyaks and two soldiers brought loading and returned to the 3560 m. camp with an accumulation of botanical material for drying. Collected down the continuation of the Sira Valley E. or a little S. of E., from camp to about 3700 m. altitude. Found Xanthampus like the N. slope thickets and forest sp. but different, also a Diplycosia and a Hypericum not found on the N. slopes. Thursday, September 22, 1938. Made a visit of inspection to the 3560 m. Camp, taking two loads of specimens for drying, and returned in the rain at 4.30. Found everything in good shape in the competent hands of LEYONG. Prepared two bundles of dried material (packed in painted canvas bags) for transport to Habbema. Dull day: mist covering the mountain: rain commenced at noon: mist sweeping down in Sira Valley Camp since mid-afternoon. Friday, September 23, 1938. Rain and mist all day, confined us to our tents. Towards evening there were signs of a break and we had about five minutes sunshine and glimpses of the peak. Four Dyaks and two convicts were sent back through the rain by the climbing party for more food - supplies for four days. Little climbing has been possible owing to the weather. Archbold says in a note that they saw sufficient to convince them that there is no approach from the east or south. When
