Several weeks had passed since the arrival of the letter; during those weeks Dom Paulo had slept badly, had suffered a recurrence of the old gastric trouble, had brooded overmuch on the past as if looking for something that might have been done differently in order to avert the future. What future? he demanded of himself. There seemed no logical reason to expect trouble. The controversy between monks and villagers had all but died. No signs of turmoil came from the herdsman tribes to the north and east. Imperial Denver was not pressing its attempt to levy taxes upon monastic congregations. There were no troops in the vicinity. The oasis was still furnishing water. There seemed no current threat of plague among animals or men. The corn was doing well this year in the irrigated fields. There were signs of progress in the world, and the village of Sanly Bowitts had achieved the fantastic literacy rate of eight per cent-for which the villagers might, but did not, thank the monks of the Leibowitzian Order.
