COLLECTED IN DUTCH NEW GUINEA. 5 



Finally, a third subsidiary Camp, VI c, was made still higher up tlie same ridge, to 

 the westward of the route, at a height of about 5500 ft. The site of this camp was 

 only separated from the northern slopes of Mt. Venus, 8470 ft., by the gully of the 

 Kemarong E^iver, and was the first collecting locality to possess that flora and fauna 

 which were found further on in the heart of the mountains at similar altitudes. 



From VI b a descent Avas made down the northern side of the ridge to Camp VII, 

 which observations by both aneroid and hypsometer place at 3585 ft. 



From Camp VII we dropped to the Hiver Nusalarong, 2960 ft., which has its source 

 in the snows of Carstensz ; this was crossed about 1^ miles above its confluence with the 

 Tsingarong, and the ascent was then made to a long north and south ridge dividing the 

 two rivers, to which it falls steeply on either hand. A temporary Camp, VII «, Avas made 

 at a height of 5430 ft. Several native villages were situated on the ridge, which has 

 evidently been long occupied, and w'as largely covered with grass, bracken, and other 

 secondary growths : portions of it bear the names of Winker-ibu and Bogger-ebok. 

 At 6300 ft., the highest point of this march, where it broadens out, it is covered witli 

 oak and mixed forest denselv clad with moss and reekins' with moisture. Thence a 

 steep descent led to a large, level inhabited clearing above the gorge of the Tsingarong, 

 where Camp VIII was placed at a height of 4970 ft. 



The journey beyond Camp VIII comprised an ascent across a ridge, a descent to a 

 river (Bandarong), and then a rise through an old grassy clearing and much secondary 

 growth to a ridge where Camp IX was placed in an inhabited clearing at 5610 ft.* : 

 this was occupied as a temporary depot by some collectors and a guard while tlie 

 rest of the journey to Mt. Carstensz was completed. 



The inhabited area of the mountains traversed lay between Camps VII and IX, 

 and the clearing that has taken place has considerably affected the flora there. 



The track onward dropped about 800 ft. to the Bandarong Pi-iver, which, coming from 

 a direction west of north, joined the Tsingarong below Camp IX, and then ascended 

 gradually up through the stream or else made detours to pass round the spurs, some- 

 times too steep to support other than scrub vegetation which overhung the river, 

 until Camp X was made in dense mossy jungle at 6370 ft. A large-fruited pandanus 

 occurred here and was eaten by the natives accompanying the expedition. 



From Camp X the banks of the river were followed with a few detours until Camp XI 

 at 8075 ft. was reached. This was placed on the boulders of the river-bed, and Casuarinas 

 draped with moss were the dominant feature of the vegetation. 



Above Camp XI the broad stony bed of the river was first followed and, when this 

 was left, an open treeless slope densely clad with scrub was traversed to the comb of 

 the ridge. This was ascended for some distance, and Camp XII was made along part of 

 its narrow extent where cloud and rain obscured the forward view. The camp was 



* All iirovioua heights by aneroid ; this and subsequent altitudes by hypsometer observations.
