"We twa hae paidled i' the burn
Frae mornin' sun till dine",

chanted Diana after them. "And that's just what I want to do. I've never had a chance yet to 'paidle' in a British burn."

"You won't to-day, then," said Geraldine, who chanced to overhear, and stopped her singing to interpolate a remark. "Shoes and stockings aren't allowed off, except in the summer term."

"Green grow the rashes, O!
Green grow the rashes, O!
The sweetest hours that e'er I spent
Were spent among the lassies, O!"

Diana stood frowning as Geraldine passed along, carolling at the pitch of her voice.

"What nonsense!" she growled. "Who made such a silly old rule? I'm not going to keep it."

"It's quite as warm to-day as it sometimes is in summer," agreed Wendy.

"I believe it's only 'swank' on Geraldine's part, because she's head prefect. I shall paddle! Just because she said I mustn't. Come on, Wendy! Let's scoot into this hollow and enjoy ourselves. Geraldine makes me feel real bad when she bosses. I want to go and break all the rules I can."
