70 lake shore, Richardson caught four rats - three Stenomys and 1 Pogonomys. The necessity of constantly watching the soldiers and prisoners erecting our tents and flys has prevented me from collecting more than a few things around camp, and these I have not had time to catalogue and prepare. Wednesday, July 27, 1938. Two degrees of frost recorded on thermometers. Heavy frost in camp and ice in our wash dish. From at least 5.45, perhaps earlier in the morning, the lake and ridges about camp were covered with a blanket of fog. This, as seems a general thing, cleared off about eight o'clock. A gloriously fine, dry day, relative humidity falling as low as 33% (at noon). Whole party invigorated by the frost and sun, and a great deal of work accomplished in constructing camp. Capt. Teerink and Dr. Huls, with five soldiers and a prisoner carrying food, made a patrol with the object of finding a path leading down to the Grand Valley. They left at 7.30 and returned at 4 PM, having followed a track going SE through a small grass valley near camp. They report a good track leading in the right direction. A party of five Papuans were seen a- bout a kilometer from camp. These men disappeared, as have all Papuans seen in the locality, in an easterly direction. An Ambonese (Marcus), going around traps in the early morning, reported having seen a party of natives on the far side of the lake. Apparently we are being closely watched. Thursday, July 28, 1938. Eighth freight flight from Hollandia. Military party received and erected as officers quarters and store their great tent: a huge thing of heavy canvas, weighing 400 kilos.
