It was marvellous with what confidence and precision they went about their ordered world.  Everything, you see, had been made to fit their needs; each of the radiating paths of the valley area had a constant angle to the others, and was distinguished by a special notch upon its kerbing; all obstacles and irregularities of path or meadow had long since been cleared away; all their methods and procedure arose naturally from their special needs.  Their senses had become marvellously acute; they could hear and judge the slightest gesture of a man a dozen paces away—­could hear the very beating of his heart.  Intonation had long replaced expression with them, and touches gesture, and their work with hoe and spade and fork was as free and confident as garden work can be.  Their sense of smell was extraordinarily fine; they could distinguish individual differences as readily as a dog can, and they went about the tending of the llamas, who lived among the rocks above and came to the wall for food and shelter, with ease and confidence.  It was only when at last Nunez sought to assert himself that he found how easy and confident their movements could be.

He rebelled only after he had tried persuasion.

He tried at first on several occasions to tell them of sight.  “Look you here, you people,” he said.  “There are things you do not understand in me.”

Once or twice one or two of them attended to him; they sat with faces downcast and ears turned intelligently towards him, and he did his best to tell them what it was to see.  Among his hearers was a girl, with eyelids less red and sunken than the others, so that one could almost fancy she was hiding eyes, whom especially he hoped to persuade.  He spoke of the beauties of sight, of watching the mountains, of the sky and the sunrise, and they heard him with amused incredulity that presently became condemnatory.  They told him there were indeed no mountains at all, but that the end of the rocks where the llamas grazed was indeed the end of the world; thence sprang a cavernous roof of the universe, from which the dew and the avalanches fell; and when he maintained stoutly the world had neither end nor roof such as they supposed, they said his thoughts were wicked.  So far as he could describe sky and clouds and stars to them it seemed to them a hideous void, a terrible blankness in the place of the smooth roof to things in which they believed—­it was an article of faith with them that the cavern roof was exquisitely smooth to the touch.  He saw that in some manner he shocked them, and gave up that aspect of the matter altogether, and tried to show them the practical value of sight.  One morning he saw Pedro in the path called Seventeen and coming towards the central houses, but still too far off for hearing or scent, and he told them as much.  “In a little while,” he prophesied, “Pedro will be here.”  An old man remarked that Pedro had no business on path Seventeen, and then, as if in confirmation, that individual as he drew near turned and went transversely into path Ten, and so back with nimble paces towards the outer wall.  They mocked Nunez when Pedro did not arrive, and afterwards, when he asked Pedro questions to clear his character, Pedro denied and outfaced him, and was afterwards hostile to him.
