17. 'What are they?'
18. 'I-er-well, I don't quite know.'
19. 'I thought as much. You have no engagements. Very well, then, I want you to start immediately for America.'
20. 'America!'
21. Do not lose sight of the fact that all this was taking place on an empty stomach, shortly after the rising of the lark.
22. 'Yes, America. I suppose even you have heard of America?'
23. 'But why America?'
24. 'Because that is where your Cousin Gussie is. He is in New York, and I can't get at him.'
25. 'What's Gussie been doing?'

28. 'In what way?'
29. 'He has lost his head over a creature.'
30. On past performances this rang true.
