The plain to the south-west was dotted with moving ostriches. Singly, in twos, in threes, in tens--they were speeding north-eastward over the desert; some on my right, some to the left. Ever and anon one or other of the groups halted and its members stood at gaze. The ostrich cannot keep on the move continuously for any length of time on a hot day. If forced to attempt doing so, death from heat-apoplexy would inevitably result. One troop, far in advance of all the others, seemed to be approaching me, but it swerved and passed to the left. It contained eleven birds, most of them young and immature; a few were full-grown hens and one was a very large cock bird. However, his plumes were sand-stained, so it is evident he had been dislodged from a nest. Far and near there must have been nearly a hundred birds in sight. No doubt some favourite food was plentiful in the vicinity from which they had been stampeded; possibly a swarm of locusts might have there hatched out. Now the birds were beginning to scud past between me and the camp, as though following a trail known to them. But they were too far off to fire at. Could it be that after all I was not to have a shot. Another troop swerved to a course calculated to bring them fairly close to the scherm; there were eight birds in it. They paused and stood at gaze for a short interval, about a mile away. Then they resumed their flight along a course which would, if they held it, bring them to within less than three hundred yards of me, on my right. On they pressed with even, steady stride. Two were young but full-grown cocks with snow-white, sumptuous plumes. Cautiously I laid my rifle over the edge of the scherm and adjusted the sight to two hundred yards. The steel barrel scorched my fingers. Would the birds stand,--that was the question of importance. A running shot is always uncertain. They halted when some two hundred and fifty yards away. Of the two gallant cocks one was manifestly superior; my bead was on him. I pulled the trigger; there was a tremendous report and the recoil nearly stunned me. My shot had missed. The birds sped away, at right angles to their original course. They became confused and ran hither and thither, for the near whiz of the bullet had alarmed them nearly as much as the distant detonation. But soon the bird I had fired at was speeding straight away from me. Within ten seconds I fired again, and he fell. The explanation of my having missed the first and easier shot is simple: I had foolishly allowed the cartridge to lie for a long time in the sun-heated chamber of the rifle; consequently the powder (one of the then new, smokeless varieties) had become too energetic. There was no violent recoil from the second shot.
