"No. If it was I'd have the door open long ago."
Sam gave a deep sigh, and then began to dance around once more to keep warm.
"Perhaps I can find a key to fit this lock," went on Tom. "I know there are keys in some of the other doors."
He ran off and soon returned with four keys, which he tried, one after another. The third was a fair fit, and with an effort the bolt of the lock was forced back.
"Hurrah! the door's open!" exclaimed Tom. "Now you can go where you please."
"Then you wouldn't stay here?" questioned Sam anxiously.
"Not much! I'd hide in one of the dormitories, and I wouldn't show myself until Captain Putnam gets back. I'll see to it that you get something to eat, and when the captain returns you can tell him that if you had remained in this place all night you would have been frozen to death."
Sam was willing enough to take Tom's advice, and was soon in the hallway. Then the door was locked again.
"It's heartless to leave poor Tubby in that cell," said Tom. "Let's get him out too."
"All right—if you can find a key to fit the lock."
