le, with an elevated ridge about 200 miles broad on
either side, the land sloping thence, on both sides, to the sea. If I am
right in believing the granite to be the cause of the elevation of this
ridge, the direction in which the strike of the rocks trends to the
N.N.E. may indicate that the same geological structure prevails farther
north, and two or three lakes which exist in that direction may be of
exactly the same nature with Lake Ngami, having been diminished to their
present size by the same kind of agency as that which formed the falls
of Victoria.

We met an elephant on the Kalomo which had no tusks. This is as rare a
thing in Africa as it is to find them with tusks in Ceylon. As soon
as she saw us she made off. It is remarkable to see the fear of man
operating even on this huge beast. Buffaloes abound, and we see large
herds of them feeding in all directions by day. When much disturbed by
man they retire into the densest parts of the forest, and feed by night
only. We secured a fine large bull by crawling close to a herd. When
shot, he fell down, and the rest, not seeing their enemy, gazed about,
wondering where the danger lay. The others came back to it, and, when
we showed ourselves, much to the amusement of my companions, they lifted
him up with their horns, and, half supporting him in the crowd, bore him
away. All these wild animals usually gore a wounded companion, and
expel him from the herd; even zebras bite and kick an unfortunate or a
diseased one. It is intended by this instinct that none but the perfect
and healthy ones should propagate the species. In this case they
manifested their usual propensity to gore the wounded, but our
appearance at that moment caused them to take flight, and this, with the
goring being continued a little, gave my men the impression that they
were helping away their wounded companion. He was shot between the
fourth and fifth ribs; the ball passed through both lungs and a rib on
the opposite side, and then lodged beneath the skin. But, though it was
eight ounces in weight, yet he ran off some distance, and was secured
only by the people driving him into a pool of water and killing him
there with their spears. The herd ran away in the direction of our
camp, and then came bounding past us again. We took refuge on a
large ant-hill, and as they rushed by us at full gallop I had a good
opportunity of seeing that the leader of a herd of about sixty was an
old cow; all the others
