GEOLOGICAL FOKMATION. QH 



We can see from this hill five distinct ranges, of which Bolengo 

 is the most westerly, and Komanga is the most easterly. The 

 second is named Sekonkamena, and the third Funze. Very many 

 conical hills appear among them, and they are generally covered 

 with trees. On their tops we have "beautiful white quartz rocks, 

 and some have a capping of dolomite. On the west of the 

 second range we have great masses of kyanite or disthene, and 

 on the flanks of the third and fourth a great deal of specular 

 iron ore which is magnetic, and rounded pieces of black iron 

 ore, also strongly magnetic, and containing a very large per- 

 centage of the metal. The sides of these ranges are generally 

 very precipitous, and there are rivulets between which are not 

 perennial. Many of the hills have been raised by granite, ex- 

 actly like that of the Kalomo. Dikes of this granite may be 

 seen thrusting up immense masses of mica schist and quartz 

 or sandstone schist, and making the strata fold over them on 

 each side, as clothes hung upon a line. The uppermost stratum 

 is always dolomite or bright white quartz. Semalembue intend- 

 ed that we should go a little to the northeast, and pass through 

 the people called Babimpe, and we saw some of that people, who 

 invited us to come that way on account of its being smoother ; but, 

 feeling anxious to get back to the Zambesi again, we decided to 

 cross the hills toward its confluence with the Kafue. The dis- 

 tance, which in a straight line is but small, occupied three days. 

 The precipitous nature of the sides of this mass of hills knocked 

 up the oxen and forced us to slaughter two, one of which, a very 

 large one, and ornamented with upward of thirty pieces of its own 

 skin detached and hanging down, Sekeletu had wished us to take 

 to the white people as a specimen of his cattle. We saw many 

 elephants among the hills, and my men ran off and killed three. 

 When we came to the top of the outer range of the hills we had 

 a glorious view. At a short distance below us we saw the Kafue, 

 wending away over a forest-clad plain to the confluence, and on 

 the other side of the Zambesi, beyond that, lay a long range of 

 dark hills. A line of fleecy clouds appeared lying along the course 

 of that river at their base. The plain below us, at the left of 

 the Kafue, had more large game on it than any where else I had 

 seen in Africa. Hundreds of buffaloes and zebras grazed on the 

 open spaces, and there stood lordly elephants feeding majestically,
