Helliconia Summer - Brian W. Aldiss [7]
And a third animal associated itself with the herd. It was a gunnadu, and Yuli saw its neck raised everywhere along the sides of the herd. As the mass of yelk moved indifferently forward, the gunnadu ran excitedly to either flank, their small heads bobbing on the end of their long necks. Their most remarkable feature, a pair of gigantic ears, turned hither and thither, listening for unexpected alarms. This was the first two-legged animal Yuli had seen; below its long-haired body, two immense pistonlike legs propelled it. The gunnadu moved at twice the speed of the yelk and biyelk, covering twice as much ground, yet each animal remained where it was in relation to the herd.
A heavy dull continuous thunder marked the approach of the herd. From where Yuli lay against his father, the three species of animal could be distinguished only because he knew what to look for. They all merged with one another in the heavy mottled light. The black cloud-front had advanced more rapidly than the herd, and now covered Batalix entirely: that brave sentinel would not be seen again for days. A rumpled carpet of animals rolled across the land, its individual movements no more distinguishable than currents in a turbulent river.
Mist hung over the animals, further shrouding them. It comprised sweat, heat, and small winged biting insects able to procreate only in the heat from the burly-hoofed flock.
Breathing faster, Yuli looked again and – behold! – the creatures in the forefront were already confronting the banks of the snowbound Vark. They were near, they were coming nearer – the world was one inescapable teeming animal. He flicked his head to look in appeal at his father. Although he saw his son’s gesture, Alehaw remained rigidly staring ahead, teeth gritted, eyes clenched against the cold under his heavy eye ridges.
‘Still,’ he commanded.
The tide of life surged along the riverbanks, flowed over, cascaded over the hidden ice. Some creatures, lumbering adults, skipping fauns, fell against concealed tree trunks, dainty legs kicking furiously before they were trampled under the pressure of the march.
Individual animals could now be picked out. They carried their heads low. Their eyes were staring, white-rimmed. Thick green trails of saliva hung from many a mouth. The cold froze the steam from their upthrust nostrils, streaking ice across the fur of their skulls. Most beasts laboured, in poor condition, their coats covered with mud, excrement, and blood, or hanging loose in strips, where a neighbour’s horns had stabbed and torn them.
The biyelks in particular, striding surrounded by their lesser brethren, their shoulders enormous with grey-bunched fur, walked with a kind of controlled unease, their eyes rolling as they heard the squeals of those who fell, and understood that some kind of danger, towards which they were inevitably to progress, threatened ahead.
The mass of animals was crossing the frozen river, churning snow. Their noise came plain to the two watchers, not solely the sound of their hoofs but the rasp of their breath, and a continued chorus of grunts, snorts, and coughs, a click of horn against horn, the sharp rattle of ears being shaken to dislodge ever-persistent flies.
Three biyelks stepped forth together on the frozen river. With sharp resounding cracks, the ice broke. Shards of it almost a metre thick reared up into view as the heavy animals fell forward. Panic seized the yelk. Those on the ice attempted to scatter in all directions. Many stumbled and were lost under more animals. The cracking spread. Water, grey and fierce, jetted into the air – fast and cold, the river was still flowing. It rushed and broke and foamed, as
