Idenburg River for while 4-5 PM though rain here. Hunting up track as usually - birds fairly common. On ridge about camp low dense shrubbery covering area approximately 150 x 200 yards - rest of country forested. Forest on ridge rather low - trees 40-60-70 feet - ground heavily mossed - aerial roots covered mosses - many slender things moss covered trunks - big trees - big clumps of moss on trunks and branches - near top of ridge fairly dense bamboo undergrowth and ground of course nearly bare - but tall trees typically mossy. A country of very steep ridges - drgins away quickly to Idenburg which through the decades has been wandering back and forth through the plain. Behind is the Soweri Valley into which we can look - its bottom about 500-1000 m. - six to eight miles long - has been garden - but upper part is now abandoned and coming back to forest - in the lower part is the pop- ulation and here this AM saw smoke rising from perhaps eight to ten communities. Water still rising in Idenburg. Transport from 1000 m. camp arrived there today - Teerink and B. L. arriving tomorrow. Guba flying PM today. Rogers walking about -- better. Archbold planning to observe hawk's nest at Hollandia. February 5, 1939. Clouds and rain on mountains inland but fairly good here all AM. Mists began to close in about noon - mist PM - no view of Idenburg. Wind and mist tonight. Had to take down flies. Hunting up track - the puzzling Pach. schlegeli relative most interesting. Message from Teerink-he and B.L. Idenburg water high - plane not before 8th.
