I recovered the camera, undamaged, and we continued our climb.

The top of the mesa was disappointing as far as game was concerned. It was covered all over with red stones, round, and as large as a man's head. Thornbushes found some sort of sustenance in the interstices.

But we had gained to a magnificent view. Below us lay the narrow flat, then the winding jungle of our river, then long rolling desert country, gray with thorn scrub, sweeping upward to the base of castellated buttes and one tremendous riven cliff mountain, dropping over the horizon to a very distant blue range. Behind us eight or ten miles away was the low ridge through which our journey had come. The mesa on which we stood broke back at right angles to admit another stream flowing into our own. Beyond this stream were rolling hills, and scrub country, the hint of blue peaks and illimitable distances falling away to the unknown Tara Desert and the sea.

There seemed to be nothing much to be gained here, so we made up our minds to cut across the mesa, and from the other edge of it to overlook the valley of the tributary river. This we would descend until we came to our horses.

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.
