Accordingly we stumbled across a mile or so of those round and
rolling stones. Then we found ourselves overlooking a wide flat
or pocket where the stream valley widened. It extended even as
far as the upward fling of the barrier ranges. Thick scrub
covered it, but erratically, so that here and there were little
openings or thin places. We sat down, manned our trusty prism
glasses, and gave ourselves to the pleasing occupation of looking
the country over inch by inch.

This is great fun. It is a game a good deal like puzzle pictures.
Re-examination generally develops new and unexpected beasts. We
repeated to each other aloud the results of our scrutiny, always
without removing the glasses from our eyes.

"Oryx, one," said F.; "oryx, two."

"Giraffe," reported B., "and a herd of impalla."

I saw another giraffe, and another oryx, then two rhinoceroses.

The three bearers squatted on their heels behind us, their fierce
eyes staring straight ahead, seeing with the naked eye what we
were finding with six-power glasses.

We turned to descend the hill. In the very centre of the deep
shade of a clump of trees, I saw the gleam of a waterbuck's
horns. While I was telling of this, the beast stepped from his
concealment, trotted a short distance upstream and turned to
climb a little ridge parallel to that by which we were
descending. About halfway up he stopped, staring in our
