of the altitude pass off. Teerink unwell: ate little breakfast or lunch and no dinner. Thinks it is probably malaria. One of the natives arriving this morning was in a state of collapse upon landing. Some of the Dyaks, and one of the Ambonese also suffered a good deal. A fine clear day with no cloud until sundown. Can see fire at a native shelter across the bay from camp. Sunday, July 24, 1938. Plane arrived at 7.40 with a sergeant, five soldiers and four convicts. Left about an hour later, taking Teerink down to the Idenburg to confer with van Arcken on the route the latter will follow in to the Grand Valley. After today's flight we have a full unit of sixteen soldiers, ten convicts, six Dyaks, two collecting boys and a cook, and the party is now large enough to stand a good chance of getting out to the Idenburg should anything happen to the plane. Richardson's tent and the radio shifted up to the new camp. Rain most of afternoon after two o'clock and thunder rattling under the edge of the plateau towards Grand Valley. Early in the afternoon smoke began to rise from the native shelter over the bay, and about 4 PM two men were seen coming along a trail in the direction of our camp. Perhaps it would have been possible to make con- tact with these two strangely nonchalant men had there been less shouting from some of our personnel. They seemed men of very good stature, light of color, and each carried on his shoulder a long cylindrical package covered perhaps with Pandanus leaves. There was light frost on the ground this morning.
