"Give it up?"
"Yes," nodded Ridgwell.
"So would any one else," grinned the Lion, "except me. Have you ever thought how the thick yellow London fogs come?" inquired the Lion insinuatingly. "Do you know what causes them?"
"No," said Ridgwell. "I don't think anybody knows that."
"I do," replied the Lion.
"What causes them, then?" asked Ridgwell.
"The yellow fogs are caused solely by the habit the other three lions have of sucking sulphur tablets whilst they are asleep," declared the Lion. "They are always sleeping, and directly two sulphur tablets are placed in the corner of each one's mouth they go on sleeping and breathing, sleeping and breathing. The result is a thick yellow fog."
"I never knew that was the cause of London fogs," mused Ridgwell.
"One of them," sighed the Lion; "and who can wonder at it? Just look at the size of their mouths."
"But your mouth is as large as theirs, is it not?" debated Christine.
