Now and then a cricket or a grasshopper made its bullet-like flight from one spot to another. Huge butterflies fluttered gaily above the silent, loathesome ground. Bees lumbered anxiously about, seeking the cross-shaped flowers of the giant cabbages which grew so rarely. Occasionally a slender-waisted, yellow-bellied wasp flashed swiftly by. But Burl did not heed any of them. Sitting dismally upon his fungus raft, floating in midstream, an incongruous figure of pink skin and luridly-tinted loin-cloth, with a greasy dead fish beside him, he was filled with a panicky anguish because the river carried him away from the one girl of his tiny tribe whose glances roused a commotion in his breast. The day wore on. Once, he saw a band of large amazon ants moving briskly over a carpet of blue-green mould to raid the city of a species of black ants. The eggs they would carry away from the city would hatch and the small black creatures would become the slaves of the brigands who had stolen them. Later, strangely-shaped, swollen branches drifted slowly into view. They were outlined sharply against the steaming mist behind them. He knew what they were: a hard-rinded fungus growing upon itself in peculiar mockery of the trees which Burl had never seen because no trees could survive the conditions of the lowland. Much later, as the day drew to an end, Burl ate again of the oily fish. The taste was pleasant compared to the insipid mushrooms he usually ate. Even though he stuffed himself, the fish was so large that the greater part remained still uneaten. The spear was beside him. Although it had brought him trouble, he still associated it with the food it had secured rather than the difficulty into which it had led him. When he had eaten his fill, he picked it up to examine again. The oil-covered point remained as sharp as before. Not daring to use it again from so unsteady a raft, he set it aside as he stripped a sinew from his loin-cloth to hang the fish around his neck. This would leave his arms free. Then he sat cross-legged, fumbling with the spear as he watched the shores go past. 2. A MAN ESCAPES It was near to sunset. Burl had never seen the sun, so it did not occur to him to think of the coming of night as the setting of anything. To him it was the letting down of darkness from the sky. The process was invariable. Overhead there was always a thick and unbroken bank
