62 in a NW direction in search of Aruacarias which are conspicuous on the skyline from the bay. Followed a good hunting track leading up the spur to 1000 feet where the oaks commence and where I started cutting track. Several small open patches crowded with Gleichenia occur along the track. Higher up in undisturbed forest, the same fern is common in the undergrowth. Cutting through poor low dry-appearing forest to about 550 meters: when, on a plateau-like area of no small sizen, there is fine tall moist forest containing big oaks, but typical rain-forest as regards undergrowth.and much like the forests of the flat ridges of the Black River. The moist hollwos especially are crowded with the climbing Cyathea? 8947. From 430 meters upwards on the spur a fine pitcher plant #8942 is common as a substage climber. The Cyathea and a very similar pitcher plant occur on the Black. Another conspicuous feature of the higher moist levels is the fine treefern #8940. The trip occupied 11 1/2 hours, during which time we had no water, except a little drained from the stems of leaves. The Dyaks seem to show no discrimination in the choice of vines from which to drink. Some which they cut contained milky sap (See small note book #2). July 1st. Plane made fifth trip with men and stores for Idenburg Camp. Aeroplane crew report that the military party found a camp recently abandoned by natives. The natives stuck arrows in the path by which they departed. July 2nd-6th. Flew to Port Moresby to procure A.W.A. field radio sets.
