"On the subject of rotten potatoes," Diavolo supplemented. Lady Fulda stared.

"Sainte Chantal, you know," said the ready Angelica. The reason was new to her, but the twins usually understood each other like a flash. "They put a rotten potato on her plate one day at dinner, and she ate it."

"She was so hungry?" suggested Lady Fulda, trying hard to remember the story.

"No, so humble," Angelica answered; "at least so they say in the book; but we don't think it could have been humility; it must have been horrid bad taste; but we're going to ask the bishop. He's so temperate, you know. We tried to discuss the matter with Father Ricardo, but he shut us up promptly."

"My dear child!" Lady Fulda exclaimed, "what an expression!"

"I assure you it is the right one, Aunt Fulda," Angelica maintained. "He got quite red in the face."

"Yes," said Diavolo, gazing at Father Ricardo thoughtfully. "He looked hot enough to set fire to us if he'd touched us."

"I should think he would have been invaluable in the Inquisition," said Angelica, to whom that last remark of Diavolo's had opened up a boundless field of speculation and retrospect. "Wouldn't you like to hear a heretic go off pop on a pile?" she inquired, turning to Father Ricardo.

The duke and Lady Fulda glanced at him involuntarily, and very good-naturedly tried to smile. This, however, did not necessitate such an effort as the mere cold reading of the twins' remark might make it appear, for they both had a certain charm of manner, expressive of an utter absence of any intention to offend, which no kindly disposed person could resist; and Father Ricardo was essentially kindly disposed.

The twins were taking their leave by this time. Angelica proceeded to deposit one of her erratic kisses somewhere on the old duke's head, with an emphasis which caused him to wince perceptibly. Then she went up to Father Ricardo, and shook hands with him.
