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.

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 o
