o'clock
Bob was generally docile , particularly when repentant ; but it was possible to drive him into an obstinate mood when nothing could be done with him . She was angry , but her anger was mainly directed against Wilkinson . After breakfast she drove off across the plain . It was about eight o'clock , but the sun was hot . The breeze was not so fresh as usual , and a bank of dark clouds rolled up above the prairie 's edge . They looked solid and their rounded masses shone an oily black , and she wondered whether they promised one of the thunder-storms that often broke upon the plains on summer afternoons . She would have welcomed the savage downpour , even if it had spoiled her clothes .
