"How did the island look?" asked Messmer, carelessly.
"Very nice. We walked all around it and ran into Doctor Clay and Mr. Dale. They were there gathering geological specimens."
"I'd like to make a collection," put in Henshaw. "By the way, Mr. Dale wasn't at supper. Did he come home with you?"
"No, we left him and the doctor there knocking off the bits of rock," answered Plum.
Merwell and Poole listened to this conversation with keen interest. They exchanged glances, and then the dudish pupil pulled his crony by the coat-sleeve and led the way to a lonely part of the campus.
"Oh, Link, do you think we took the doctor's boat by mistake?" asked Poole, with something akin to terror in his tones.
"Hush! not so loud!" warned Merwell. "If we did, you don't want to let anybody know it."
"But what shall we do? The doctor and Mr. Dale can't leave the island without a boat."
"I know that. But don't you say anything—unless you want to get into hot water."
"But they may have to stay there all night!" continued the thoroughly frightened Nat.
