John beamed complacently.

"I got through that last bit rather well," he said; "'pon my word,
there's more in this dancing than I thought. I quite enjoyed that
twinkling business."

"Have another one," I suggested.

"Don't mind if I do," said John. "May I have the pleasure?" with a
courtly bow to Margery.

They re-commenced.

"That's right," said Margery; "now two forward."

"I must have a natural genius for dancing," said John, conversing
easily; "I seem to ... Do we twinkle next?"

"Yes," said Margery.

"I seem to fall into it naturally."

"Look out!" shrieked Margery.

I don't know exactly what happened; I rather think John got his gears
mixed up in the twinkling business. At any rate, one of his feet shot
up in the air, he made a wild grab at nothing and tripped heavily
backwards into the hearth. The piano was drowned in general uproar.
