"It is." Aunt Caroline corroborated grimly.

"This is a surprise," exclaimed the professor. As we have noted before, he liked to be truthful when possible. "How'd'do, Aunt! However did you get here?"

"You see Dr. Rogers who has kindly accompanied me."

"John Rogers here? With you?" In rising amazement.
