May-4 mile north of the junction of the west-flowing Foria River with the Mongi River at an elevation of about 1,900 feet ( meters). Masses of flowstone a few feet inside the entrance, out of which flowed a small stream, prevented any exploration of Buma Cave, but we mist-netted the entrance and at dusk we captured 18 Hipposideros. A call for carriers to assemble on May 30, went out during this period. The carry from Pindiu to the village of Zengaren on the northern slopes of Mt. Rawlinson, was a difficult one. May 30 saw us "break" (cross) the Kua River at an elevation of about 1,550 feet. We then passed through the Mission Station AT Mindik and spent the night at the village of Tumnang where we collected frogs. At Mindik we were cordially received by Mr. and Mrs. Werner Jacobsen, German Lutheran missionaries, who told us about a small natural history museum with New Guinea specimens at the Lutheran Training Center in Neuendettelsau, Germany. May 31, a Sunday, turned into a day of rest and a night of frog collecting at Tunang because the carriers preferred not to work.
