Grandma smiled. “She is a very nervous woman, and has been up nights a great deal with a sick baby. She lay down about two hours ago to take a nap. The house has a great many mice in it, and one got in her hair. It was entangled for a few seconds, and she was terrified. It would be very much more afraid of her than she would be of it.”

Tom and Roger laughed uproariously, so uproariously and joyfully that Grandma’s black eyes went to them, rested on them, and did not leave them.

But they did not care. They had not enjoyed themselves so much for years, and they were going to continue doing so, although their punishment was bound to come. Presently, when the conversation between Grandma, Margaretta, Selina, and Berty became really interrupted by their giggling, the old lady left her seat and came over to them.

“Have you been acting like this all the evening?” she asked, severely.

Tom looked at Roger, and Roger looked at Tom.

“And teasing poor Berty?”

Again they looked at each other.

“When I was a girl,” said Grandma, musingly, “I remember getting into those gales of laughter. How I revelled in that intoxication of the spirit! I would even scream with delight, and if I were alone with my girl companions would sometimes roll on the ground in ecstasy. You are pretty old for such pranks, but I see you are ready for one. You ought to be alone for a time. Follow me,” and she left the room.

She took them down-stairs. “Where are we going?” asked Roger, humbly, and nudging Tom.
