CLAV. (surprised,). You refused it when it was offered you.

JABEZ. My dear sir, I get safety devices sent me every day. I can't use 'em all. You never told me you used your thing yourself. It makes a world of difference. And you hadn't written a book about it.

CLAV. I see.

JABEZ. I thought you would. Come, we're getting on famously. Now if I adopt the respirator, do you think the book need be published?

CLAV. (curtly). Yes.

JABEZ. Oh, come, doctor, don't be stupid.

CLAV. (pause). I'll tell you what I will do, if you like. I'll wire the publisher to postpone its issue and have a note put in stating that it's been adopted here. But I'll not cancel my book.

JABEZ. That might do.

CLAV. (reflectively). It'll be a good advertisement for the respirator.

JABEZ. And a good thing for the patentee, eh, doctor?
