relief party, sent from the coast colonies by the governor, Treich 
Laplene. Both parties followed to the coast the river Akba, which 
is navigable as far as Attakru. 
The greater part of the country included within the great northern 
bend of the Niger proves to be drained by the Comoe and the Volta, 
which latter is formed by three large tributaries, the White, Red, and 
Black Volta. Though there is no distinct range separating the basins 
-of the Niger from those of the coast rivers, yet isolated granitic peaks 
rise above the general platform. In the west these culminate in 
Natinian Sikasso (2,560 ft.) Southward of this the platform sinks 
gradually, and here the Lahu and the Dahbu rise. Among isolated 
peaks more to the east is that of Kernono (4,757 ft.), which turns the 
course of the Comoe from east to south. From the Volta, which is 
surrounded with low hill-ranges, an extensive table-land stretches east- 
ward, ascending from 3,250 feet to Nauri, in the southeast of Waga- 
dugu, 5,905 feet high, and the highest point of the watershed, sepa- 
rated from the Gambaga range by the valley of the East or White 
Volta, which rises in Bussang. Sandstone and swamp-ore prevail in 
this region, which is poor, except in humid places. From March to 
June the heat was 104? in the shade, 140° in the sun. Captain Bin- 
ger surveyed his route with the compass, and determined thirteen points 
astronomically. The natives belong to seven different groups: the 
Mondungo (Samory, Kong, Worodugu, Kurudugu, Gudja, etc.), colo- 
nised in all directions; the Sieneren or Sienufs, ranging from Tieba 
to Pegue, Follona, Djimmi, and Worodugu ; the Gurungu, who prevail 
in Gurunsi and part of Bussang ; the Moor Mossi ; the Haussa, west of 
the White Volta; the Ashanti, as far as the Black Volta; and the 
Fulbe, whose chief abode is further north, but who have colonies to

The Zambezi Delta.—In the March issue of the Proc. Roy. 
Geog. Soc., 1890, D. J. Rankin gives an account of the Zambezi delta, 
and especially of the Chinde mouth thereof. The Quaqua cannot now 
be called strictly an outlet of the Zambezi, as the bulk of the waters 
* which flow into it are derived from the drainage of the Shimwara and 
Achigunda hills and of the Borore heights. From Quillimane to the 
sea stretches a flat sodden swamp, bordered by mangroves. The tide 
rises to Mogorumbo, but from Lokololo to Quillimane goods have to 
be transported in lighters. The Kongoni mouth has 12 to 14 feet 
draught, but is not suitable, as its coasts are mere mangrove Swamps, 
covered at high tides. The island of Inhainissengo is becoming rapidly
