On they went, through thorn jungle, over fallen timber, dodging tree trunks. Now the big bull tacked round a tree with the deftness of a well-handled yacht. Now a tall cow bent her swan-like neck and ducked marvellously under the spreading branches of an acacia. Guy felt many a scratch and stab as his excited pony plunged through the thorny brakes. In a patch of _haak-doorn_, through which they forced a passage, his left stirrup-leather and stirrup were ripped clean from the saddle. He lost his hat. These were mere nothings in the heat of a chase such as this, and he galloped on. At last they were clearing the forest. Now they were on the grass, with nothing but wide, open plain in front of them. Barring falls, that big bull must surely soon be his. The great giraffe was now running apart from the rest of the troop, going great guns, and manifestly thinking only of the safety of his own skin. The smooth, long, shuffling walk had been long since exchanged for a strange rocking gallop, in which the hind legs were straddled widely, and the long neck swung up and down in a rhythmic motion, which reminded Guy of a gigantic pendulum. Meanwhile the long black tail, screwed oddly up, was executing wild and fantastic flourishes. The chase swept headlong over the pale yellow grass plain. A mile and more had been accomplished since they quitted the timber. The great bull was running well, but Guy noted with a sense of exultation that he was now no more than eighty yards ahead. Another mile slipped by. The bull was tiring; he was now no more than sixty yards ahead. Guy shook up his pony and gave him just one firm touch of the spur. The gallant beast answered by a wonderful and prolonged spurt, which carried his rider to within twenty yards of that great dappled figure, rocking and swaying, like some tall ship on an uneasy sea, in front of them. One more touch of the spur and Guy was within eight paces of the giant's tail. Dropping his reins, he raised his rifle and fired. The heavy Martini bullet struck the giraffe fair, close to the root of the tail, and the great beast staggered to the shot. Still it pressed on. Guy instantly reloaded, and, taking aim as well as the motion of his pony would allow him, fired again. This time his bullet raked the giant's heart. Guy saw that its end had come, and galloped wide to the left. The bull faltered in his stride, staggered, strode on again, again staggered, and then with a crash that literally shook the earth fell to rise no more. The mighty limbs kicked twice or thrice, once the long neck was raised, then a shiver passed over the dappled frame, and the beast was dead.
