53 From Hollandia to about the 8 km. post, the road is through rain-forest covering limestone hills in which most of the drainage goes underground. Saw only one running stream. Rain-forest not very rich in spp. though tall in some parts. Selaginellas are common ground cover and form much of the low vegetation along the track. A clumped Arenge and a tallish palm with rather narrow leaflets (branic?) common. Pandanus of one ot two spp. also common. Celanus and Freycinetias scarce. Both smooth and prickly sago in small swamps. Forest little disturbed. At 8 km. begin the gardens of the Tabati people. Casuarina nodiflora is common in the second growths and one sees ahead open grasslands. The 9 km. peg is out in t the open grassland slopes beyond the forest. These grasslands undoubtedly second- ary. The process by which they are formed--clearing for gardens--can be seen around the edges. Dominant grass Themeda triandea forming a thick cover 1 meter high with taller Ophiurus abundant. Euphorbia servulata, Knoxia corymbx, Sapubia trifide seen. Melastema sp. present as a shrub in grass but Mussaenda much commoner. Red-flowered Metrosidius? 8801 here and there as a shrub protruding above the grass. No trees out on grass. Casuarina nodiglora and Pandanus common in light forest left in ravines (perhaps largely second growths resisting the invasion of grass). The beginning of the grasslands coincides with a change in rock from limestone to serpentine (?) but this probably because the soils weathered from the serpentine (?) are more fertile. Soil black A horizon of a foot or less over yellowish pebbly B horizon perhaps clayey: soil of ridge ??? red. The road follows along the grassy hillsides at about 200-300 feet altitude to a point above Pim where it joins the more used road leading from Pim to Sentani at about 10 km. (10 KM peg missing). The roads junction is a saddle from which opens out a view of the valley of Creek in which are situated first Steuben's dwelling and then Brinkmann's plantation. About 1/2 km. from the gap on the down grade, the grass ends in the sago swamps which seem to occupy a good deal of this valley. A little past Nrinkmann's plantation the 13 km. peg is on low ground with sago and neglected native plantings of coconuts, cassava and bananas. Lalang, Hibiscus
