John (impressed). Do you think that now?
Mackenzie. You know I take a particular interest in bellows myself. I tried my hand a good while working out a new kind of bellows, and I flatter myself that I know something about the subject.
John. Aye. (Looking round.) Where's Daniel? Daniel! Are you there, Daniel? (Daniel comes out and stands near the door.) You could maybe bring them plans out you're working at and explain it to them now, Daniel. Eh? And wait, Sarah wants to hear it too. (Calling.) Are you there, Sarah?
Daniel (seating himself sadly). Aye. She's in there somewhere taking stock.
John (going next door to rooms). Are you there, dear? (Sarah comes out.) Daniel's going to explain the thing to us, and you wanted to hear about it. Didn't you?
Sarah. I'm just dying to know all about it. (She seats herself to the right at back. Andy sits on one side of the table and Mackenzie at the other, expectantly, while John goes over to the fireplace almost opposite his brother.) You know, Mr. Daniel, that's one thing we want very bad in our house—a good fan bellows.
Daniel. They are very useful, very.
John. Aye. They are that. (To Sarah). He has a good head on him, Daniel. Eh? (To Daniel.) Now go on and make it very plain so that every one can follow you. Bring out the plans and show us.
Daniel (uneasily.) I can explain it better without them. (After a pause.) Well, I suppose this subject of bellows would come under the heading of pneumatics in natural philosophy.
John. Oh, now, don't be going off that way. Could you not make it plainer nor that?
