"Knew what you were doing? Didn't any one ever tell you that I have a search-light and a telescope in my office?" Uncle Tom laughed. "Oh, I keep track of things even if I do seem to be otherwise occupied. So look out for yourself! Beware! My eyes may be upon you almost any time."
"I am not afraid, sir," smiled the boy.
"And you have no cause to be, either, my lad," was Uncle Tom's serious rejoinder. "Now you and Jean fix up some date to see the works. Why not to-morrow? It is Saturday, and she will not be at school."
"But I work Saturday mornings, Mr. Curtis."
"Can't somebody else do your work for you?"
"I have never asked that."
"Well, I will. We'll arrange it. Let us say to-morrow then. Take Jean and explain things to her. You can do it, can't you?"
"I think so. Most of the process I understand now, and if there is anything that I need help about I can ask."
"That's right. Just go ahead and complete the girl's education in glass-making so she can write her Boston uncle that she is now qualified to superintend any glass works that may require her oversight."
Jean laughed merrily.
