97 A dull cloudy day: rain intermittently in camp from 1 PM. Rain com- menced about 11 AM at 3900 m. burst of showers coincided with a shift of wind from SE to NE. Monday, September 12, 1938. The event of the day for me was a trial of strength with Myer-Drees. In a discussion of working plans for our combined botanical work on Satur- day, I suggested, and he agreed, to proceed to the Middle Camp today and collect there, returning on the 15th. Seeing that he had made no prepara- tion to start, I asked in a conversational way whether he was ready to go, and was thereupon informed that he intended to postpone the trip until after the ascent of Mt. Wilhelmina. Some plain talk followed, with the result that Myer-Drees departed for the Middle Camp after lunch, with three Dyaks. He travelled with a convoy returning after delivering supplies. Hear that several Dyaks are on strike at Lake Habbema. Loads too heavy, they say, and the country too cold. The first day since our arrival on the sixth. Clear frosty morning soon clouding but spots of sunshine to 5 PM. First rain at 1.15: heavy rain 6.30 to 8 PM with thunder rumbling to NE. It is warm in the tent tonight: 53 degrees F. Tuesday, September 13, 1938. This morning at 6.15 the temperature against the frozen wall of our tent was 23 degrees F. Grass temperature at 6.40 was -5 degrees C: standard minimum -2 degrees C. A beautifully fine day followed, the peaks being quite clear until late afternoon. Van Arcken and self went up to the top camp, partly to see the country and partly to receive mails dropped by parachute. Two parachutes were dropped.
