far experienced at this camp. Very strong squalls from N. between 8 and 10 PM. Sergeant Krutzen down with fever. Rand also unwell. Van Arcken arrived from the 2100 m. camp at 3 PM and returned in the rain shortly after five. Collected about three-quarters of an hour east along the Idenburg road. A poor morning, though several new forms obtained. Have now about 80 spp. of ferns from this locality. Sunday, January 22, 1939. Very high more or less broken overcast and weak sun to 3 PM: wind SW: lightermist than usual with change of wind to N. later in day: no rain: a few stars at 9 PM. The heavy rain squalls last night shook our tents violently and a Hydno- phytum, blown from a tree, went through the dining fly. Idenburg high and a rise of another meter will flood Bernhard Camp. A gold mines plane, scheduled to fly from the prospecting base on the Digoel to Hollandia, turned back owing to bad weather. Flying conditions better here than for many days. Van Arcken, from his camp at 2100 m. signalled good visibility in the mountains until mid morning. A tin-can code has been arranged for signals between the two camps. One kerosene tin hoisted on a pole signifies Upper Idenburg clear, two tins that Mt. Wilhelmina is visible, and three tins open weather in both directions. Rand ill, much vomiting and some fever: perhaps gastric malaria. Sent the boys into the field and myself labelled specimens and cleared up some other outstanding work in camp.
