69 place. Now, after having spent twelve days at the shut-in, fright- fully sultry and anopheles infested "new camp" under the hills, this seems not such a bad place after all. A few days ago the Gold Mines people landed an exploration party 80km. up the riv er, probably at the junction of the A River. A Gramman amphibian and an old navy Fokker plane carried the party. The former succeeded in landing its com- plement on a sandbank but the current was too strong for the old Fokker and she had to return without landing her men. A day or so later, more men were landed by the Gramman. Today supplies were dropped by parachute and the company is considering the establishment of a base at Bernhard Camp, from which supplies could be sent up river by launch. April 19th. Collected from canoe along the edges of the lagoon (not a good word for the old river cut-off) to about a mile above camp. Though preferable to the mosquito- infested forests of the foot of the mountain, for comfort, and a quick and east way to collect, the heat of the open river is trying in a small prow and all manner of crawling biting things find their way into the canoe from the vegetation along the banks. Ants, spiders, insects, everything that gets shaken down into the water, is able to swim, and immediately makes for the canoe as the nearest object onto which it can crawl. Van Arcken has given me a record of water levels taken daily since the camp was established last July and with these to show depth and period of inundation, I hope to perhaps arrive at some understanding of forest succession on the flood plains. April 20th. Rather a poor day, spent on the small creeks to S--SE of camp, and in the forests of the edge of the hills below New Camp where I made a forest-interior picture
