"No, Bunny, I can't," said the boy sadly, after working patiently at the key for some time. "It's no use, I can't do it at all."
"Oh dear, oh dear!" cried Bunny in a miserable voice, "what shall we do? Miss Kerr, dear, we can't open the door, it's locked quite fast."
"Take the key out of the lock and push it under the door, and I will try and open it from this side," said Miss Kerr; "it was really very naughty of you to lock yourselves up in such a way. But be quick and give me the key."
After a good deal of pulling and tugging, Bunny at last managed to get the key out of the lock, and kneeling on the floor she tried with all the strength of her tiny hands to push it out under the door.
But the key was too large or the door fitted too closely, and the little girl gave a cry of alarm as she found that it was quite impossible to get it out into the passage.
"Oh, Mervyn, dear, it won't go out! Oh! Miss Kerr, what shall we do?" she cried, bursting into tears; "if we can't open the door what shall we do?"
"And I am so hungry," said Mervyn in a doleful tone. "How nasty it will be to be stuck in here for ever! Oh, pray open the door! Oh! pray open the door, Miss Kerr."
"Throw the key out of the window, Bunny," said Miss Kerr, "and I will go round and pick it up, and let you out in a minute."
"Oh! the window is shut. The window is shut," cried the two children in despair, "and we cannot reach to open it. What shall we do? What shall we do?"
"Good gracious!" exclaimed Miss Kerr, "who can have shut the window?"
