'We don't want little boys in here,' she said crushingly.

'I don't care,' shouted the indignant youth through the keyhole. 'I don't want to play with a lot of stupid girls—so there! I shall go and talk to Joe.'

The museum proved a great fund of interest, for nearly every article had a history, and the guests wandered round the room examining the maps and various specimens of art which adorned the walls. Dorothy was trying the piano, for she played well, though her touch had not half the firmness of Lilian's.

'What's this?' asked Mary, hunting through a pile of old music inside the ottoman, and fishing out a manuscript page in Lilian's neat hand.

'Oh, don't!' cried Lilian, blushing hotly. 'Let me have that, Mary, please. I didn't know I had left it there.'

'What is it?' exclaimed all the girls, whose curiosity was naturally aroused. 'Peggy, you tell!'

'If you dare, Peg!' said Lilian.

But for once Peggy turned tell-tale, and disclosed the secret.

'It's a coon song she's made up herself,' she declared stoutly.
