The Mopane-Tree (`Bauhinia') Is Remarkable For The Little Shade
Its Leaves Afford.
They fold together and stand nearly perpendicular
during the heat of the day, so that only the shadow of their edges
comes to the ground.
On these leaves the small larvae of a winged insect
appear covered over with a sweet, gummy substance. The people collect this
in great quantities, and use it as food;* and the lopane -
large caterpillars three inches long, which feed on the leaves,
and are seen strung together - share the same fate.

* I am favored with Mr. Westwood's remarks on this insect as follows:
"Taylor Institution, Oxford, July 9, 1857.
"The insect (and its secretion) on the leaves of the bauhinia,
and which is eaten by the Africans, proves to be a species of Psylla,
a genus of small, very active Homoptera, of which we have
one very common species in the box; but our species, Psylla buxi,
emits its secretion in the shape of very long, white, cotton-like filaments.
But there is a species in New Holland, found on the leaves
of the Eucalyptus, which emits a secretion very similar
to that of Dr. Livingstone's species. This Australian secretion
(and its insect originator) is known by the name of wo-me-la,
and, like Dr. Livingstone's, it is scraped off the leaves
and eaten by the aborigines as a saccharine dainty. The insects found
beneath the secretion, brought home by Dr. Livingstone,
are in the pupa state, being flattened, with large scales
at the sides of the body, inclosing the future wings of the insect.
The body is pale yellowish-colored, with dark-brown spots.
It will be impossible to describe the species technically until we receive
the perfect insect. The secretion itself is flat and circular,
apparently deposited in concentric rings, gradually increasing in size
till the patches are about a quarter or a third of an inch in diameter.
Jno. O. Westwood."

In passing along we see every where the power of vegetation in breaking up
the outer crust of tufa. A mopane-tree, growing in a small chink,
as it increases in size rends and lifts up large fragments of the rock
all around it, subjecting them to the disintegrating influence
of the atmosphere. The wood is hard, and of a fine red color,
and is named iron-wood by the Portuguese. The inhabitants,
observing that the mopane is more frequently struck by lightning
than other trees, caution travelers never to seek its shade
when a thunder-storm is near - "Lightning hates it;" while another tree,
the "Morala", which has three spines opposite each other on the branches,
and has never been known to be touched by lightning, is esteemed,
even as far as Angola, a protection against the electric fluid.
Branches of it may be seen placed on the houses of the Portuguese
for the same purpose. The natives, moreover, believe that a man
is thoroughly protected from an enraged elephant if he can get
into the shade of this tree. There may not be much in this,
but there is frequently some foundation of truth in their observations.
At Rapesh we came among our old friends the Bushmen, under Horoye.
This man, Horoye, a good specimen of that tribe, and his son Mokantsa
and others, were at least six feet high, and of a darker color
than the Bushmen of the south. They have always plenty of food and water;
and as they frequent the Zouga as often as the game in company with which
they live, their life is very different from that of the inhabitants
of the thirsty plains of the Kalahari. The animal they refrain from eating
is the goat, which fact, taken in connection with the superstitious dread
which exists in every tribe toward a particular animal, is significant of
their feelings to the only animals they could have domesticated
in their desert home. They are a merry laughing set,
and do not tell lies wantonly. They have in their superstitious rites
more appearance of worship than the Bechuanas; and at a Bushman's grave
we once came to on the Zouga, the observances showed distinctly
that they regarded the dead as still in another state of being;
for they addressed him, and requested him not to be offended
even though they wished still to remain a little while longer in this world.
Those among whom we now were kill many elephants, and when the moon is full
choose that time for the chase, on account of its coolness.
Hunting this animal is the best test of courage this country affords.
The Bushmen choose the moment succeeding a charge, when the elephant
is out of breath, to run in and give him a stab with their long-bladed spears.
In this case the uncivilized have the advantage over us,
but I believe that with half their training Englishmen would beat the Bushmen.
Our present form of civilization does not necessarily produce effeminacy,
though it unquestionably increases the beauty, courage,
and physical powers of the race. When at Kolobeng I took notes
of the different numbers of elephants killed in the course of the season
by the various parties which went past our dwelling, in order to form
an idea of the probable annual destruction of this noble animal.
There were parties of Griquas, Bechuanas, Boers, and Englishmen.
All were eager to distinguish themselves, and success depended mainly
on the courage which leads the huntsman to go close to the animal,
and not waste the force of his shot on the air. It was noticeable
that the average for the natives was under one per man, for the Griquas
one per man, for the Boers two, and for the English officers twenty each.
This was the more remarkable, as the Griquas, Boers, and Bechuanas
employed both dogs and natives to assist them, while the English hunters
generally had no assistance from either. They approached
to within thirty yards of the animal, while the others stood
at a distance of a hundred yards, or even more, and of course
spent all the force of their bullets on the air.
