So I returned to the library. By tea-time I had got as far as this:—

"Adventures with a Camera in Somaliland.

"Lecture delivered before the Blanktown Literary and Philo—— "

And then I had an idea. This time a brilliant one.

"Celia," I said at tea, "I have been wondering whether I ought to take advantage of your generosity."

"What generosity?"

"In letting me deliver this lecture."

"It isn't generosity, it's swank. I want to be able to tell everybody."

"Ah, but the sacrifices you are making."

"Am I?" said Celia, with interest.
