nine o'clock
The girls went home silently ; they were never great talkers . Flora sat down in the sitting-room with her aunt ; Nancy went up-stairs to the chamber where she slept with Flora , and got her little purse out of the corner of her bureau drawer . She counted the eight cents , and puzzled over the problem how to increase it to fifty . She puzzled over it all the rest of that day until she went to sleep at nine o'clock . The next day was Sunday ; she puzzled over it as she sat in the pew in church , but she could not arrive at any solution . However , the next morning she had an inspiration . Her mother sent her over to Aunt Lucretia 's on an errand .
