four o'clock
Tim watched them for a little while , dimly aware that he watched something `` perfectly magnificent . '' His eyes followed one bird after another , caught in a sudden little rapture he could not understand ... then turned and saw his bed , flushed with early pink , across the room . With a running jump he landed among the sheets , rolled himself up into a ball , and promptly fell asleep again . It was not yet four o'clock . Across the landing , meanwhile , Judy , wakened by a brush of feathery wind , was at her window too . She felt very sure of something , although she did n't in the least know what . It was the same thing that Tim and Uncle Felix knew , only they knew they did n't know it , whereas she did n't know she knew it .
