9 o'clock
`` Guess I 'll take the wind out of Muriel 's sails ! '' she murmured . The list was beautifully wrapped up in a sheet of new tissue-paper , and Merle carried it proudly to school . Miss Mitchell was generally in the study from about 8.45 till 9 o'clock , so there would be nice time to present it before call-over . On this particular morning , however , as fate would have it , the study was unoccupied . Merle peeped in many times , went to the hostel , asked the boarders if they had seen Miss Mitchell , but was utterly unable to find her . She seemed to have mysteriously disappeared , and only walked in , from no one knew where , just in time to take the register .
