"Open the door!" he called out.
"I can't," was the answer, in a young child's voice. "It's locked."
"Can't you turn the key?"
"No; I don't know how."
"You will have to get through the transom," said the clerk. "If we only had a step-ladder."
"Lift me up and I'll get through," said Rupert. "I have practiced in a gymnasium."
"Very well, if you think you can."
The clerk bent over, and Rupert, standing on his shoulders, was lifted so that he could reach the transom.
Then, by a skillful movement, he raised himself still farther till he could look inside.
