JUNE On June 1 we traversed the uplands between the Kua and Bulum Rivers. This was an easier carry than the first day because it involved only modest dips and climbs out of creek beds of less than 1,000 feet. We encountered our first beech tree (Nothofagus sp.) at an elevation of 4,650 feet as we approached the divide between the rivers at 4,900 feet. Noon found us in Ogeramnang. Near here in 1929 Ernst Mayr, who was to become one of the world's leading ornithologists, collected a peculiar long-footed rodent that became the type of Leptomys ernstmayri. Later in the month we were to collect a fine series of topotypes of this hydromyine. We spent the night at Selimbing at (4,850 ft.) after passing through the villages of Kemai and Semketa. June 2 saw us "break" the Bulum at (2,500 feet), a roaring mountain torrent with its headwaters in the distant Saruwaged Range. We passed near the village of Maran (3,200 ft.) on the way to the log bridge crossing. The rough slippery trail now led up the forest covered slopes of the Rawlinson Range. Here and there we found natives clearing the primary forests for gardens. At 3,100 ft. we saw our first Rhododendron sp. We passed through the old village of Zengaren at 3,800 ft., and the six hour carry ended at Zengaren #2, perched high on the north slope of Mt. Rawlinson at 4,500 feet. Gaytson, the village counselor, whom I had met at a gathering of counselors chaired by the District Officer, Des Ashton, in Pindiu, promised to show us a good camp site near water the next morning. The village was perched high above the Bulum River with a dramatic view northwest to the Saruwaged Range and northeast towards the Cromwell Mountains, our two next objectives of the trip. We spent the evening trading for trophy
