Ugh-lomi became alert. He wished he had a flint, but the throwing-flint he had carried in a thong about his waist was--like the axe--heaven knows where. The Master Horse turned his head, and Ugh-lomi became aware of an eye and teeth. He whipped his leg into a position of security, and hit at the cheek with his fist. Then the head went down somewhere out of existence apparently, and the back he was sitting on flew up into a dome. Ugh-lomi became a thing of instinct again--strictly prehensile; he held by knees and feet, and his head seemed sliding towards the turf. His fingers were twisted into the shock of mane, and the rough hair of the horse saved him. The gradient he was on lowered again, and then--"Whup!" said Ugh-lomi astonished, and the slant was the other way up. But Ugh-lomi was a thousand generations nearer the primordial than man: no monkey could have held on better. And the lion had been training the horse for countless generations against the tactics of rolling and rearing back. But he kicked like a master, and buck-jumped rather neatly. In five minutes Ugh-lomi lived a lifetime. If he came off the horse would kill him, he felt assured. Then the Master Horse decided to stick to his old tactics again, and suddenly went off at a gallop. He headed down the slope, taking the steep places at a rush, swerving neither to the right nor to the left, and, as they rode down, the wide expanse of valley sank out of sight behind the approaching skirmishers of oak and hawthorn. They skirted a sudden hollow with the pool of a spring, rank weeds and silver bushes. The ground grew softer and the grass taller, and on the right-hand side and the left came scattered bushes of May--still splashed with belated blossom. Presently the bushes thickened until they lashed the passing rider, and little flashes and gouts of blood came out on horse and man. Then the way opened again. And then came a wonderful adventure. A sudden squeal of unreasonable anger rose amidst the bushes, the squeal of some creature bitterly wronged. And crashing after them appeared a big, grey-blue shape. It was Yaaa the big-horned rhinoceros, in one of those fits of fury of his, charging full tilt, after the manner of his kind. He had been startled at his feeding, and someone, it did not matter who, was to be ripped and trampled therefore. He was bearing down on them from the left, with his wicked little eye red, his great horn down and his tail like a jury-mast behind him. For a minute Ugh-lomi was minded to slip off and dodge, and then behold! the staccato of the hoofs grew swifter, and the rhinoceros and his stumpy hurrying little legs seemed to slide out at the back corner of Ugh-lomi's eye. In two minutes they were through the bushes of May, and out in the open, going fast. For a space he could hear the ponderous paces in pursuit receding behind him, and then it was just as if Yaaa had not lost his temper, as if Yaaa had never existed.
