"I must know the exact size, or I can't suit you. What is it the key of?"
"A drawer."
"I can go with you to the house."
"That won't do," said Humpy. "I've lost the key, and I don't want the boss to know it. He'd find out if you went to the house."
"Then I'll tell you what you can do. Take an impression of the lock in wax. I'll give you some wax, and show you how. Then I'll make a key for you."
"Can you do it right off? I'm in a great hurry."
"Yes, my son, I'll attend to it right away."
He brought a piece of wax, and showed Humpy how to take an impression of a lock.
"There," said he, laughing, "that's the first lesson in burglary."
Humpy lost no time in hurrying back and following the locksmith's instructions. He then returned to the shop.
