SEEN ACROSS TEN MILES OF sunlit water, Lorbanery was green, green as the bright moss by a fountain's rim. Nearby, it broke up into leaves, and tree-trunks, and shadows, and roads, and houses, and the faces and clothing of people, and dust, and all that goes to make up an island inhabited by men. Yet still, over all, it was green: for every acre of it that was not built or walked upon was given up to the low, round-topped hurbah trees, on the leaves of which feed the little worms that spin the silk that is made into thread and woven by the men and women and children of Lorbanery. At dusk the air there is full of small grey bats who feed on the little worms. They eat many, but are suffered to do so and are not killed by the silk-weavers, who indeed account it a deed of very evil omen to kill the grey-winged bats. For if human beings live off the worms, they say, surely small bats have the right to do so.
