99 The only news was, however, that more food had been sent to their bivouac. This, in conjunction with the present indications of a spell of wet weather, will probably mean the delay of the climb for several days. Weather fine with broken clouds to about noon. Rain commenced at 1 PM and continued intermittently, heavily at times to the present moment - 8.45 PM - when another shower is falling. Saturday, September 17, 1938. Took two of my Dyak collecting boys, AIT and UNGAU, and moved up to the [illegible] 3800 m. (Sira Valley) Camp under Mt. Wilhelmina. Sira Valley Camp is situated about two km. slightly S. of E. from Wilhelmina-top, on the timbered side of a small grass pocket, with a 60 ft. waterfall nearby. Timber, in the form of broken struggling scrubs of Vaccinium and Drimys, reaches to about 3900 m. about camp, and perhaps 100 m. higher in the upper part of the Sira Valley. Above the closed timber [illegible] Coprosma occurs, usually in tree-fern to about 4150 m. Camped here now are Archbold, Rand, Teerink and Toxopeus. Sunday, September 18, 1938. A big day in the field. Collected to the head of Sira Valley and at 4150 m., crossed over a divide to a hollow directly under the north face of the peak containing a small lake or rather a collection of shallow ponds at about 4120 m. altitude. Rand and Teerink went farther to the west, past the ponds and discovered Kremer's 1925 route, or at least a place appearing to correspond with Kremer's Wilhelmina Pass.
