ways.

At first we followed between the river and the low hills, but
when the latter drew back to leave open a broad flat, we followed
their line. At this point they rose to a clifflike headland a
hundred and fifty feet high, flat on top. We decided to
investigate that mesa, both for the possibilities of game, and
for the chance of a view abroad.

The footing was exceedingly noisy and treacherous, for it was
composed of flat, tinkling little stones. Dried-up, skimpy bushes
just higher than our heads made a thin but regular cover. There
seemed not to be a spear of anything edible, yet we caught the
flash of red as a herd of impalla melted away at our rather noisy
approach. Near the foot of the hill we dismounted, with orders to
all the men but the gunbearers to sit down and make themselves
comfortable. Should we need them we could easily either signal or
send word. Then we set ourselves toilsomely to clamber up that
volcanic hill.

It was not particularly easy going, especially as we were trying
to walk quietly. You see, we were about to surmount a skyline.
Surmounting a skyline is always most exciting anywhere, for what
lies beyond is at once revealed as a whole and contains the very
essence of the unknown; but most decidedly is this true in
Africa. That mesa looked flat, and almost anything might be
grazing or browsing there. So we proceeded gingerly, with due
regard to the rolling of the loose rocks or the tinkling of the
little pebbles.
