Had a good morning, collecting 50 spp. on the rockslide, and the xxxxxxxx and birdboysxxxwere xsent down and in the scrub below. Toxopeus returned to the 1800 m. camp, and the mammal and bird boys who were sent down to collect at his 1530 m. camp came up to the 2100 m. camp. February 3rd. A miserable misty day without any sun. Mist closed down about 9 o'clock, prior to which some fair views were to be had to east and south: light rain all day from 11 AM: slight breeze from NE. Gathered about 30 numbers, few of them of much importance, along the crest of the ridge along the path leading N to the summit, about 1/2 mile beyond camp from which, at 2250 m., the main ridge sends down spurs to the Idenburg on one side and to the Sauweri on the other. February 4th. Mist most of day though a good view over mountains in early morning and Idenburg fairly clear in afternoon. Wind westerly. Collected in the low scrubs on the sides of the bluff below camp. Some very steep slopes covered with ferns--Gleichenia spp. and Dipteris conjugate. February 5th. Idenburg under cloud all day and no good views of mountains: mist in forest after 9 AM, though sun shining through most of morning: light drizzling rain 2-6.30 PM. when wind changed from W to NE: heavy short wind squalls threatening to wreck exposed tents and flies in early evening. Had a good morning in the field. Collected along the new-cut path to the 2220 m
