About nine o'clock
The children , meanwhile , were sleeping soundly in their hard bed . They were so tired that they did not wake up even when a tiny stream of water broke through a crevice in the rocks and splashed down on Tonio 's head . It ran off his hair just as the rain ran off the thatched roof of their little adobe hut . About nine o'clock the rain stopped and the moon shone out from behind the clouds . An owl hooted ; a fox ran right over the roof of their cave , making a soft pat-pat with his paws that would have frightened them if they had heard it , but they slept on . At last , however , something did wake Tita . She sat up in terror .
