"Have you any engagement for tonight?" asked Innis.
"We were going to the theatre," said Grace.
"Isn't there any place we could go to a dance?" inquired Paul.
"Say, he's crazy on these new dances!" exclaimed Dick. "I caught him doing the 'lame duck' the other night, with the broom for a partner."
"Oh, do you do that?" cried Mabel.
"A little," admitted Paul.
"Will you show us how the steps go?" asked Irene.
"And I know the 'lace glide,' and the 'pivot whirl,'" put in Dick. "You needn't think you can walk off with all the honors," he said to his chum, laughingly.
"Oh, let's stay at the hotel and dance tonight," suggested Mabel. "Mamma will chaperone us. It will be more fun than the theatre."
"We'll have to hire dress suits," said Innis. "We didn't bring them in the airship."
