73 16 soldiers, prisoners and Dyak carriers left on an exploration patrol to the Grand Valley. (34 men all told in Teerink's party). They disappeared into the mist in "military" order, Teerink in the lead followed by half his soldiers, then the prisoner carriers with the rest of the soldiers on their heels, and last of all, guarding the rear, the heavily laden Dyaks. The carriers are, according to Teerink, loaded with packs of 30 kilos. To me the Dyaks seemed to be carrying much more than that. This, our first day in the field, proved very profitable. My collections for the day number about 40 spp. Rand got 12 spp. of birds, including a cormorant, two ducks (Salvadorina and a kind of black duck), a coot, pippit, brown finch, etc. Toxopeus reports a new butterfly, the fifth sp. collected at the camp, and also found a display tree of Macgregor's bird of paradise. (50 spp. of plants gathered). Heavy rain from 7 to 8 PM. During the rain a corporal, two soldiers and a Dyak of Teerink's party came into camp carrying Teerink's personal convict cook Mlong who had been injured by a rock falling on his stomach. Tuesday, August 2, 1938. A dull, cloudy day: heavy shower with small hail at 5.30 PM. Slight showers afterwards. Collected about 30 plants, excluding a number of lichens, mosses, and liverworts on the shrubby Libocedrus ridges S. to SW from camp. Yesterday and today Rand I have worked till dark preparing specimens. No contact with Papuans since Sunday. Saw a party of fifteen people, in- cluding two boys travelling west over the grasslands on opposite side of the lake. There were others on the ridge above them, whom I heard but did not see.
