Mangrove Association at Langg&n. 



On the spit of land between the two bays a Papuan " campong " was 

 built among the mangroves, where *^Egiceras floridum flourished as a round 

 shrub about 1 m. high, covered with the white flowers and quaint fruit. On 

 a tree overhanging the sea-water, * Lycopodium phlegmariodes with Dendro- 

 bium pseudo-ealceolum in flower and various Dischidia spp. abounded. 

 *Pandanus polycephalus with small red fruit bunched at the apex of the 

 peduncle, common through the Moluccas, with *Excacaria Agallocha and 

 the climbers * Tristellateia australasica, a mass of yellow flowers, *Derris uligi- 

 nosa and Sarcolobus retusus, marked the land-edge of the mangrove-spit ; 

 while Freycinetia Beccarii, Erythrospermu>n candid^,, the yellow-flowered 

 *JDurandea parvifolia, a Gardenia sp., with *Pollia sorzogonensis as under- 

 growth, were found where the ground was more consolidated, and young 

 colonies of *Pigafetta pilaris were quite abundant towards the shores of the 

 second bay. 



Wousi and Genbela. 



Wousi, in earlier times the watering-place for all the boats calling at 

 Dorei Bay, where the Papuan " campong," with a fringe of houses built over 

 the sea, still stands, is a tiny valley cut out of the " korang " range by the 

 action of the stream, the range from this point gradually sloping to the level 

 ground. At the time of my stay Wousi was also the site of the Military 

 Bivouac, and the base for the work of the Exploration detachments so suc- 

 cessfully organized from 1907 by the military authorities at Amboina. The 

 survey having been completed by the successful results of Captain Opper- 

 man's Expedition (27, 542-3) the bivouac has now been closed. 



In the military cartographical office hung a huge map of Dutch New 

 Guinea, originally blank, filled in by degrees with tracings of the work 

 of each Exploration detachment in turn. When I was shown this map 

 only one blank space remained, viz. the source of the Mamberamo River. 

 With the successful results of Captain Opperman and Mr. Langeler that 

 blank space has also disappeared, and with it this admirable era of organized 

 exploration is closed, the whole of the Dutch possessions in North New 

 Guinea being now mapped out. 



At Wousi, under the shade of the overhanging trees, the ideal and 

 classical anchorage was reserved for naval and military needs, and all the 

 ground underneath the beautiful century-old trees behind the beach was 

 cleared and grass sown, forming a fine green sward, where the quarters of 

 the military and naval officers were built. Farther up the valley were the 

 open barracks for the native troops, carefully arranged with intersecting 

 white paths, beyond which again excellent gardens had been made up the 

 bu.iki of the stream, where all the vegetables for the needs of the forces were
