Mackenzie. Aye. I'm a specialist on that, you know. I'm the writer of the inventions column in the Scottish——

Mary. Yes. Yes. That's all right. I know. Are all the inventions you write about good things?

Mackenzie. Eh? Ninety-nine per cent. rotten, lassie. Ninety-nine per cent. perfectly rotten. People don't invent a reciprocating piston that works every day in the week, or a fan bellows either.

Mary. But if you liked the inventor you could do him a good turn all the same?

Mackenzie. Aye. I did that often.

Mary. Then could you do a good turn for Uncle Dan?

Mackenzie. Give the bellows a boost up. No, Mary. I could nae. I don't like to grieve you, but committing perjury—No. I couldn't do it, Mary.

Mary (coming closer). Yes. You would. You'd do it for me. Won't you?

Mackenzie. Eh?
