About twelve miles above this rapid (21° 30’ E. lon.) the Bangasso: 
discharges into the right bank of the Mobangi. Up to this point 
the natives had invariably been friendly, offering for sale all kinds 
of provisions, but here difficulties began. The Mombongo and 
Takoma tribes which inhabit both banks were decidedly hostile, so, 
as the navigation was obstructed by rocks and sandbanks, Van 
reached 22° 55’ on the Welle, and as both points are in 4° 20’ N. 
lat., there can be little doubt of the identity of the Welle and 
Mobangi. 
GEOGRAPHICAL News.—Another voyage made by Dr. Schrader 
up the Empress Augusta River (New Guinea) confirms his previous 
opinion as to the important character of this waterway, which 
probably rises within the Dutch portion of the island, since the 
amoa reached a spot distant but a few miles from the boundary 
line, and 380 miles from the mouth of the river. Not only the 
main river, but several of its affluents, are navigable for long dis- 
ces during the rainy season. :
