Piunde-Aunde 78 in brief bursts; wind movement from NE; clouds over the Ramu all day; more thunder in Bundi Pass this evening. Botanized to the NE of camp in an area of wet, grassy glades, cold and with a very poor flora. Examined one of the larger forest patches across from camp in the afternoon and found a Galium, new for the mountain so far as I know. Profit- able botanizing is about finished for this camp. Today I caught my first butterfly for the camp. It fell from a tree to the grass, apparently half frozen; looks like a Delias, but like no Delias I have seen before. Yesterday I caught my first Odonata for the mountain; 10 specimens of a small damselfly, the male of which has blue bandings, the female pale brown all over. Self and boys did some bug hunting this afternoon; one boy with the beating sheet. Self dredged 2 spp. of small mollusks from the shallows of the lake and from the outlet stream. The damselfly must be of very recent emergence; I could hardly have missed it before. Photographed for Van his fourth or fifth Neohydromys, and a pretty-faced Pseudocheirus, with curious peglike upper incisors, strange for both of us. Both specimens came from the vicinity of Keglsugl. Van, following a report by John of owl pellets under a rock overhang some 500 ft. up the slopes opposite camp, examined the site and brought back a plastic bag full of material. A very curious little moss grew on dry ground under the overhang, apparently fertilized by the owl pellets and droppings. Friday, June 26. Max. 13.5, min. 3 O. Clear morning; heavy frost on the grass; wind from N to NE, bringing a lot of cloud in morning; heavy clouds driving across Bundi Pass, to the high country clear. Another of those curious blackish bright days at high altitudes. Took advantage of the good weather to climb along the trail to the summit to an altitude of 13,450 ft. (aneroid at camp before I left 12,000 ft.; on my return 12,050 ft.). A steep pinch of about 200 ft. between the lakes; slopes above the second lake very steep for some hundreds of feet, the heavy, rich-looking brown soil wet, worn by recent traffic, and the footing slippery in places. Travel mainly on rock above about 13,000 ft. and footing excellent. My main ob- jective was the collection of Papuapteris linearis, of which I found numerous clumps beginning at 13,400 ft. in the long-grass community of the alpine grassland. This strange, erect fern is called BINGA in the Chimbu language. It is carried down as a symbol of prowess by men who climb the mountain. I discovered it on Mt. Albert Edward in 1933, and Hoogland & Pullen collected it on Wilhelm in 1946. Growing with the fern (in interstices between grass tussocks) was little yellow-flowered Ischnea, a dwarf composite of the high places. For botanical notes see small notebook. From about 13,500 ft. up to 13,500 ft. the mountain side is strewn with the remains of an American Liberator bomber which crashed and exploded, killing all hands, during World War II. They had bad luck. With 100 feet more altitude they would have cleared the crest of the ridge which they flew into, in the night. John returned from down the mountain, having completed the establishment of our #2 Mt. Wilhelm Camp on Pengagl Creek at about 9000 ft. elevation.
