"What is '_Papa_'?" Lady Adeline asked anxiously.

"Very nice, or you wouldn't have married him," answered Angelica. "Go on,
Diavolo. If you sing flat, I'll slap you."

"If you're impertinent, miss, I'll put you out," Diavolo retorted.

"Go on," said Evadne sharply, fearing a fight.

But to everybody's intense relief the prince laughed, and then the twins'
distinguished manners appeared in a new and agreeable light.

"_Papa--Papa--Papa_,"--they sang--"_Papa says--that we--that
we--that we are little devils! and so we are--we are--we are and ever
shall be--world without end_."

"_I am a chip_," Diavolo trilled exquisitely; "_I am a chip_."

"_Thou art a chip--Thou art a chip_," Angelica responded.

"_We are both chips_," they concluded harmoniously--"_chips of the
old--old block! And as it was in the beginning is now and ever shall be,
world without end. Amen!_"

"You sang that last phrase flat you--_pulp!_" cried Angelica.

"I can't both sing and play," Diavolo protested.

"You'll say you can't eat and breathe next," she retorted, giving his hair
a tug.
