Early one morning-we were still on the Isiola-we set forth on our horses to ride across the rolling, brush-grown plain. Our intention was to proceed at right angles to our own little stream until we had reached the forest growth of another, which we could dimly make out eight or ten miles distant. Billy went with us, so there were four a-horseback. Behind us trudged the gunbearers, and the syces, and after them straggled a dozen or fifteen porters.
The sun was just up, and the air was only tepid as yet. From patches of high grass whirred and rocketed grouse of two sorts.
They were so much like our own ruffed grouse and prairie chicken that I could with no effort imagine myself once more a boy in the coverts of the Middle West. Only before us we could see the stripes of trotting zebra disappearing; and catch the glint of light on the bayonets of the oryx. Two giraffes galumphed away to the right. Little grass antelope darted from clump to clump of grass. Once we saw gerenuk-oh, far away in an impossible distance. Of course we tried to stalk them; and as usual we failed. The gerenuk we had come to look upon as our Lesser Hoodoo.
The beast is a gazelle about as big as a black-tailed deer. His peculiarity is his excessively long neck, a good deal on the giraffe order. With it he crops browse above high tide mark of other animals, especially when as often happens he balances cleverly on his hind legs. By means of it also he can, with his body completely concealed, look over the top of ordinary cover and see you long before you have made out his inconspicuous little head. Then he departs. He seems to have a lamentable lack of healthy curiosity about you. In that respect he should take lessons from the kongoni. After that you can follow him as far as you please; you will get only glimpses at three or four hundred yards.
We remounted sadly and rode on. The surface of the ground was rather soft, scattered with round rocks the size of a man's head, and full of pig holes.
"Cheerful country to ride over at speed," remarked Billy. Later in the day we had occasion to remember that statement.
The plains led us ever on. First would be a band of scattered brush growing singly and in small clumps: then a little open prairie; then a narrow, long grass swale; then perhaps a low, long hill with small single trees and rough, volcanic footing.
Ten thousand things kept us interested. Game was everywhere, feeding singly, in groups, in herds, game of all sizes and descriptions. The rounded ears of jackals pointed at us from the grass. Hundreds of birds balanced or fluttered about us, birds of all sizes from the big ground hornbill to the littlest hummers and sun birds. Overhead, across the wonderful variegated sky of Africa the broad-winged carrion hunters and birds of prey wheeled. In all our stay on the Isiola we had not seen a single rhino track, so we rode quite care free and happy.
Finally, across a glade, not over a hundred and fifty yards away, we saw a solitary bull oryx standing under a bush. B. wanted an oryx. We discussed this one idly. He looked to be a decent oryx, but nothing especial. However, he offered a very good shot; so B., after some hesitation, decided to take it. It proved to be by far the best specimen we shot, the horns measuring thirty-six and three fourths inches! Almost immediately after, two of the rather rare striped hyenas leaped from the grass and departed rapidly over the top of a hill. We opened fire, and F. dropped one of them. By the time these trophies were prepared, the sun had mounted high in the heavens, and it was getting hot.
Accordingly we abandoned that still distant river and swung away in a wide circle to return to camp.
Several minor adventures brought us to high noon and the heat of the day. B. had succeeded in drawing a prize, one of the Grevy's or mountain zebra. He and the gunbearers engaged themselves with that, while we sat under the rather scanty shade of a small thorn tree and had lunch. Here we had a favourable chance to observe that very common, but always wonderful phenomenon, the gathering of the carrion birds. Within five minutes after the stoop of the first vulture above the carcass, the sky immediately over that one spot was fairly darkened with them. They were as thick as midges-or as ducks used to be in California. All sizes were there from the little carrion crows to the great dignified vultures and marabouts and eagles. The small fry flopped and scolded, and rose and fell in a dense mass; the marabouts walked with dignified pace to and fro through the grass all about. As far as the eye could penetrate the blue, it could make out more and yet more of the great soarers stooping with half bent wings.
Below we could see uncertainly through the shimmer of the mirage the bent forms of the men.
We ate and waited; and after a little we dozed. I was awakened suddenly by a tremendous rushing roar, like the sound of a not too distant waterfall. The group of men were plodding toward us carrying burdens. And like plummets the birds were dropping straight down from the heavens, spreading wide their wings at the last moment to check their speed. This made the roaring sound that had awakened me.
A wide spot in the shimmer showed black and struggling against the ground. I arose and walked over, meeting halfway B. and the men carrying the meat. It took me probably about two minutes to reach the place where the zebra had been killed. Hundreds, perhaps thousands, of the great birds were standing idly about; a dozen or so were flapping and scrambling in the centre. I stepped into view. With a mighty commotion they all took wing clumsily, awkwardly, reluctantly. A trampled, bloody space and the larger bones, picked absolutely clean, was all that remained! In less than two minutes the job had been done!
