720 General Notes. 
the basins of the Komati and Lomati rivers and that of the Kaa 
and Crocodile. The Lebombo range, which forms the boundary 
between the Portuguese possessions and the Transvaal, is but a 
series of low ranges not rising above 900 to 1,000 feet. From the 
terminus of the Portuguese railway an east and west line is projected 
across the Transvaal, ascending the Drakensberg, and rising at one 
point to 5,884 feet. There is abundant evidence that the Kaap 
valley was extensively worked, centuries ago, by a white race. 
Quarries, shafts, tunnels, adits, the remains of well-made roads, and 
pits of ore lying beside them for shipment, are to be found, and it 
would seem that the works were abandoned precipitately. Mr. 
Stuart attributes these workings to the Portuguese of the seven- 
teenth century. The valley is not considered healthful, but Barber- 
ton, the chief settlement, enjoys a salubrious climate. The lowest 
strata in the valley are a series of soft gray argillaceous shales, 
greatly tilted by volcanic action. ese seem to correspond wit 
the Silurian, and in the Drakensberg are overlaid by Devonian 
strata. 
KUND AND TAPPENBECK’s EXPEDITION TO THE CAMEROONS. 
—Among the results of the above expedition are q), the knowledge 
that the Beundo and Great Njong rivers have their sources above 
the cataract region ; (2), that the water-parting between the rivers 
that discharge on the coast, and those that flow into the Congo basin 
oes not lie near the Cameroons coast, as was previously supposed ; 
(3), that the water-parting between the left tributaries of the Binue 
and the rivers which water the German Cameroons region also lies 
far into the interior; (4), that the racial parting between the Bantu 
and Sudan negroes does not lie in the direction of Adamawa, but 
runs in a southerly direction, and is formed by the Aannaga a 
Great Njong River, and lies about 145 miles from the coast; an 
5), that volcanic formations do not occur in the mountains ee 
iately north of the Zannaga, nor in the region between 1t, and the 
coast. The Beundo River discharges at Little Batanga, and is known 
in the interior as the Njong or Nlong, while the Great Njong dis- 
charges at Malimba by the Borea and Bornu mouths, and mto ; 
Cameroons River by the Quaqua mouth. A profile accompanymg 
the repért shows a coast plain about seventy feet above the pat 
succeeded by a sharp slope rising to a height of 3,000 to 4,000 
above sea-level (the Crystal Mountains), beyond which the egos 
slopes gently to about 2,300 feet. Both rivers have a second pa 
aract region in the interior, with a long stretch of navigable wat of 
between it and the lower cataracts, The Zannaga no doubt cart 
off the water of a great river region.
