Edith rose to this with the eagerness of the trout she had caught.

"The humour of a nation doesn't depend on the number of jokes in its sublimest tragedy," she said. "Let us judge English humour by the funny things in Hamlet."

Dodo gave a commiserating sigh.

"That wasn't a very good choice," she said. "There are the grave-diggers, and there's Polonius all over the place. The most serious people see humour in Polonius. Why didn't you say Milton? Now it's too late."

Jack suddenly laughed.

"I beg your pardon," said he; "I wasn't thinking about Milton at all, but a vision of Dodo's tea-gown appeared to me, as I last saw it. Yes. Take Milton, Edith. Dodo can't give you a joke out of Milton because she has never read him. Don't interrupt, Dodo. Or take Dante. Ask me for a joke in Dante, and you win all down the line. Take Julius Cæsar: take any great creature you like. What you really want to point out is that great authors are seldom humorous. I agree: one up to you. Take a trout—I didn't catch any."

Edith did precisely as she was told.

"I hate arguing," she said. "Dodo insisted on arguing about middle-age all the afternoon. In the intervals she talked about putting pennies on the line. She said it was enormous fun, but she forgot all about them when she had put them there."

"Don't tell David, Jack," said Dodo, aside. "All right. Dodo's got middle-age on her mind. She bought some spectacles once."

"My dear, we've had all that," said Dodo. "What we really want to know is how you are to get gracefully old, while you continue to feel young. We're wanting not to be middle-aged in the interval. There is no use in cutting off pleasures, while they please you, because that makes you not old but sour, and who wants to be sour? What a poor ambition! It really is rather an interesting question for us three, who are between fifty-four and sixty, and who don't feel like it. Jack, you're really the oldest of us, and more really you're the youngest."
