"Look here," said I. "Imagine that all the francs in the world have turned into herrings."
"What a joy shopping would be!" said Berry.
"Yes," said Jill faithfully.
"Well, on Monday you go and buy a pound's worth of herrings. Fish is plentiful, so you get fifty-six."
"Yes."
"During the night herrings rise."
"Get quite high," said Berry. "You have to get out of bed and put your purse on the landing."
Adèle began to shake with laughter.
"Yes," said Jill earnestly.
"So that the next morning," I continued desperately, "when you come to buy another pound's worth of herrings, you only get fifty-three."
