CHAPTER IV

But at last the perfect opportunity came. I received a letter from a botanical paper asking for an article on the Flora of Trench Life.

"Horray!" said Celia. "There you are."

I sat down and wrote the article. Working up gradually to the subject of rats, and even more gradually intertwining it, so to speak, with the subject of cats, I brought off in one perfect climax the great Joke.

"Lovely!" said Celia excitedly.

"There is one small point which has occurred to me. Rats are fauna, not flora; I've just remembered."

"Oh, does it matter?"

"For a botanical paper, yes."

And then Celia had a brilliant inspiration.

"Send it to another paper," she said.

I did. Two days later it appeared. Considering that I hadn't had a proof, it came out extraordinarily well. There was only one misprint. It was at the critical word of the Joke.
