The Congo—The Rev. G. Grenfell continues to explore the 
Congo tributaries in the steam launch Peace. The Itimbiri was 
found to be navigable as far as the Lobi falls (23° 21’ E. long. 
and 1° 50’ S. lat). The Mbura divides into two at three or four 
miles from its junction with the Congo, and both branches are 
barred by rapids or falls, the southern one having a cascade forty 
feet high. e Lomami is a fine river with a tortuous channel 
and a swift current. In August, 1885, the Lulongo was ascended 
for nearly 700 miles. Its principal affluent is the Lopori, in 1° 
12’ N. lat. The Juapa and Bosira form Stanley’s Black river, 
which enters near the equator. The Juapa was navigated for 
about three hundred miles, but hostile natives compelled the 
explorers to retreat before reaching the head of navigation. The 
Bosira was navigable for about two hundred miles. Mr. Grenfell 
dwells upon the richness of the Upper Congo basin. 
Herr Wolff, a traveler in the service of the Congo Free State, 
has discovered an affluent of the Kassai likely to be of great 
future importance. This was ascended by the steamer Vorwarts 
in February and March to a distance of 430 leagues from its 
mouth, and one of its northern affluents brought the traveler to 
within a week’s march of Nyangwe. There were no cataracts, 
and the stream might have been navigated still further had not 
the steamer met with an accident. By this route the great north- 
ern bend of the Congo, with its cataracts, can be avoided and an 
easy passage traced across Africa. 
African News.— According to the observations of MM. G. 
Valdall and K. Knutson, the Rio del Rey, which forms the bound- 
arm is connected with the old Calabar river. ; 
quet, of the Péres du Saint-Esprit mission, has founded a station 
upon the plateau of Amboella, in 15° 3’ S. lat. and 16° 14 
long., at an altitude of 4540 feet, on the right bank of the ~*~ 
shilanda, a tributary flowing into the Cunene on its left bank. 
M. Duparquet gives information about the Kuerahi and the 
Kavundu, which flow between the Cunene and the Okavango. 
The former of these two rivers, hitherto unknown to Europeans, 
crosses the territory of Evare, at the extremity of which it forms 
a lake.——Mr, Cope Whitehouse has, with the assistance of Herr 
Stadler, an engineer in the Egyptian service, thoroughly m 
veyed the Reian basin. The total area of the depression is esti- 
f 280 feet
