"There is something in that, little lady," Uncle Tom answered, slipping one of his big hands over the two tiny ones in the girl's lap. "Giusippe and I will keep the sea monsters out of your path, then; and the land monsters, too, if we can. Now it is time you children got to bed, for to-morrow you must make an early start. You'd better telephone your aunt or uncle that you are going to stay here to-night, Giusippe. If you do not work to-morrow you will not need to get to the factory until Jean and I do; it will be much simpler for you to remain here and go down with us in the car. I'll call up your boss and explain matters. Good-night, both of you. Now scamper! I want to read my paper." * * * * The next morning the Curtis family was promptly astir, and after breakfast Uncle Tom with his two charges rolled off to the factory in the big red limousine. "Your superintendent says you are welcome to the morning off, Giusippe," Mr. Curtis remarked as they sped along. "But he did have the grace to say he should miss you. Now it seems to me that if you are to give Jean a clear idea of what we do at the works you better begin with the sheet glass department. That will interest her, I am sure; later you can show her where you yourself work." The car pulled up at Mr. Curtis's office, and they all got out. "Good-bye! Good luck to you," he called as the boy and girl started off. Jean waved her hand. "We will be back here and ready to go home with you, Uncle Tom, at one o'clock," she called over her shoulder. "We won't be late, sir." "See that you're not. I shall be hungry and shall not want to wait. I guess you'll have an appetite, too, by that time." "Is sheet glass blown, Giusippe?" inquired Jean, as they went across the yard. "I hate to ask stupid questions, but you see I do not know anything about it." "That isn't a stupid question. Quite the contrary. Yes, sheet glass is blown. You shall see it done, too." "But I do not understand how they can get it flattened out, if they blow it." "You will." The boy led the way through a low arched door. Before the furnaces within the great room a number of glass-blowers were at work. They stood upon wooden stagings, each one of which was built over a well or pit in the floor, and was just opposite an opening in the furnace.
