"And I," Adams put in, definitely. "I must photograph everything, before it is touched; therefore I must be the first on board. I must do some autopsies and also——"

"Of course. You're right," Deston said. "And if I haven't said it before, I'm tremendously glad to have a Big Brain along ... oh, excuse that crack, please, Dr. Adams. It slipped out on me."

Adams laughed. "In context, I regard that as the highest compliment I have ever received. To you youngsters my advanced age of fifty-two represents senility. Nevertheless, you men need not 'Doctor' me. Either 'Adams' or 'Andy' will do very nicely. As for you two young women——"

"I'm going to call you 'Uncle Andy'," Barbara said, with a grin. "Now, Uncle Andy, you being a Big Brain—the term being used in its most complimentary sense—and the way you talked, one of your eight doctorates is in medicine."

"Of course."

"Are you any good at obstetrics?"

"In the present instance I am perfectly safe in saying——"

"Wait a minute!" Deston snapped. "Bobby, you are not——"

"I am too! That is, I don't suppose I am yet, since we were married only last Tuesday, but if he's competent—and I'm sure he is—I'm certainly going to! If we get back to Earth I want to, and if we don't, both Bun and I have got to. Castaways' Code, you know. So how about it, Uncle Andy?"

"I know what you two girls are," Adams said, quietly. "I know what you two men must of necessity be. Therefore I can say without reservation that none of you need feel any apprehension whatever."
