Sept.2 Lake Kallima, Netherlands New Guinea 3225m. 9 sticky traps - 0 birds. The morning the Yula arrived with 2700 lb of mun, gun, and food for the military party (see page 39a) Specimens were returned to Hollandia. Afternoon spent on the Lake with Reed looking for white winged ducks. Vonken (50 ±) was seen but we walked to get away from it. Sept.3 Lake Kallima, Netherlands New Guinea 3225m. 9 sticky traps - 1 Pseudochirons. The unsettled weather prevented the Yula from making its trips to Kallima today. Heavy clouds this morning and the sky had intermittent storms. I found equipment, developed pictures today. Most of the time however was spent in 'piddling'. Sept.4 Lake Kallima, Netherlands New Guinea 3225 m. 9 sticky traps - 0 The morning the Yula came in with its provisions and gun for the American party. The presence of the planes in camp is certainly stimulating not only to the Congress & all the other members of the expedition Intarian and chapellon need a vacation at this time. A short observation trip (3 1/4 hrs) was taken over the vicinity of Willemine. B.D. wanted to look for a suitable route of ascent of the mt. With a party (10 ±) as large as we have an easy ascent will be essential. The best and most logical route at present seems to be along the west ridge. The mt appears to be smooth or scree rather than rock climb which I had expected. Yula left for Hollandia soon after.
