At length we dropped below the screen of trees, and could stand upright and straighten the kinks out of our backs.  But now a new complication arose.  The wind, which had been the very basis of our calculations, commenced to chop and veer.  Here it blew from one quarter, up there on the side hill from another, and through the bushes in quite another direction still.  Then without warning they would all shift about.  We watched the tops of the grasses through our binoculars, hoping to read some logic into the condition.  It was now four o’clock—­our stalk had thus far consumed two hours—­and the roan must soon begin to feed.  If we were going to do anything, we must do it soon.

Therefore we crept through a very spiky, noisy jungle to its other edge, sneaked along the edge until we could make out the tree, and raised ourselves for a look.  Through the glass I could just make out the roan’s face stripe.  He was still there!

Quite encouraged, I instantly dropped down and crawled to within range.  When again I raised my head the roan had disappeared.  One of these aggravating little side puffs of breeze had destroyed our two hours’ work.

The outlook was not particularly encouraging.  We had no means of telling how far the animal would go, nor into what sort of country; and the hour was well advanced toward sunset.  However, we took up the track, and proceeded to follow it as well as we could.  That was not easy, for the ground was hard and stony.  Suddenly C. threw himself flat.  Of course we followed his example.  To us he whispered that he thought he had caught a glimpse of the animal through an opening and across the stream bed.  We stalked carefully, and found ourselves in the middle of a small herd of topis, one of which, half concealed in the brush, had deceived C. This consumed valuable time.  When again we had picked up the spoor, it was agreed that I was to still-hunt ahead as rapidly as I could, while C. and Kongoni would puzzle out the tracks as far as possible before dark.

Therefore I climbed the little rocky ridge on our left, and walked along near its crest, keeping a sharp lookout over the valley below—­much as one would hunt August bucks in California.  After two or three hundred yards I chanced on a short strip of soft earth in which the fresh tracks of the roan going uphill were clearly imprinted.  I could not without making too much noise inform the others that I had cut in ahead of them; so I followed the tracks as cautiously and quietly as I could.  On the very top of the hill the roan leapt from cover fifty yards away, and with a clatter of rocks dashed off down the ridge.  The grass was very high, and I could see only his head and horns, but I dropped the front sight six inches and let drive at a guess.  The guess happened to be a good one, for he turned a somersault seventy-two yards away.

C. and Kongoni came up.  The sun had just set.  In fifteen minutes it would be pitch dark.  We dispatched Kongoni for help and lanterns, and turned to on the job of building a signal fire and skinning the trophy.
