81 Piunde-Aunde/Pengagl Creek and much like another myrt, which was common at Top Camp. The recognizable subalpine forest ended at about 11,000 ft. At that altitude the forest was largely of the Decaspermum, the other just mentioned myrtaceous tree. Libocedrus and a Timonius came in close below the lip of the glacial valley and were abundant with the two myrts, and occasional Podocarpus compactus (this may be P. papuanus, the two being hard to distinguish). The Decaspermum continued to the foot of the escarpment at 10,400 ft. An Ilex was very abundant at 10,800 ft. and almost constituted a vegetation zone of its own. (For other notes on vegetation see small notebook). Reached Pengagl Creek at 2:00 and had lunch there. Moved on down the creek at 3 o'clock and reached camp at 4:00. Altitude at my lunch place at the foot of the escarpment was 10,100 ft., at the new camp 9,700 ft. On the 8th I made the new camp site 9,150 ft. From the foot of the escarpment, I could see some half mile or more up the ravine of the creek a big pale scar left by the rockslide which, about 1\frac{1}{2} years ago according to a local native who joined me on the trail, must have dammed the creek. A flash flood when the dam broke scoured the bed of the creek and up- rooted most of the forest on flood terraces for the whole length of the creek down past our camp. It must have been a flood of great violence. And so recent was it that blobs of soil and collections of small stones are still atop some of the rocks in the stream bed, there not having been enough rain to wash them off. John surpassed himself in building our part of the camp. The hut he built, 16 x 20 feet, I have named Pengagl Lodge. It is thatched with Pandanus leaf, one wall is of the same material, the others of bark (Libocedrus and Elaeocarpus), and there is a big open fire-place of sticks and bark; and stones cemented with mud. On either side of the fireplace is a deep seated bench of ski lodge type. There is a dining table of round sticks covered with a square of new Pandanus matting, some shelving, and by the time I got there our tube beds of canvas stretched on small poles had been rigged. There is a good pandan leaf kitchen for the cook. The boy's house, of the same construction, had chinks on the roof too noticeable to pass in- spection, and I had John rig a fly over it. The local natives had just completed a snug, very smoky low pandan house for their own use, as visitors to our camp. Work tents for Van and me had been rigged on a practically devegetated flood bank of the creek. We had 44 carriers, men, boys and women, for the move down the mountain. Tuesday, June 30. The morning fine and clear early; turned cloudy about 9 a.m. (the clouds coming through the Bundi Gap, approximately east); steady rain from 2:30 to about 4:00 p.m. Had my work tent moved up to a safe place on the high bank, beside our living quarters; Van's, being in a much less risky position on the flood terrace, remains there, at least for the time being. My day spent in the preparation of yesterday's gathering of plants numbering about 45. Have used up all my diyers and corrugates and still have a few numbers on hand. Van and John shot two large Pipistrellus last evening; a marsupial mouse brought from a native today. Purchase of mammals from natives is now strictly limited to the very rare little hydromine mice and the marsupial mice. Bats are another exception, and today a native produced a specimen of the mountain, Syconycteris.
