Several times Philippe had sent money home to his parents.
But one day Tom said, "I must ask you to give me all the money you make. It is I who feed and clothe you. And now you belong to me."
Philippe had a strange feeling then.
He answered, "But I must send my parents some of what I make. It is only fair."
Tom scowled fearfully and snapped, "You will do as I say!"
After that time Philippe worried. He told Zelie, but she said nothing. She looked very sad, however.
Then one evening while they were having supper by the side of the road, Tom announced, "It is time that Philippe learned our business, eh, Zelie?"
Zelie started and turned very pale, but she did not answer.
