"People often take us for twins," conceded Merle.

Iva Westwood shook her head.

"No one with eyes, surely! You're alike in a way, but not very. Opal Earnshaw was fearfully angry that you beat her in maths. She's been cock of the walk till now."

"Which is Opal Earnshaw?"

"That fair girl who sat near you."

Merle's face darkened.

"That was why she tried to take it out of me in the French class, then?"

"Oh, Opal tries to take it out of everybody. She won't be very pleased you two have come, I expect. You're too old to stand her bossing."

"Why do other people stand it?"

"Well, you see, she's head of the school, and Miss Pollard and Miss Fanny are her godmothers."
