Dr. Mopp calls at the Chigley Pottery to buy a vase for his sister Millicent, and gets a demonstration of how a potter uses his wheel. Lord Belborough arrives in Bessie to collect a crate of pottery, and they go with him to Treddles wharf, where he picks up a mysterious crate. Dr. Mopp asks the Camberwick Green villagers if they know what is inside the crate. Mrs Honeyman suggests that it must be something to do with the six o'clock whistle at the biscuit factory, which proves to be correct. At 6.00 the workers leave the factory and Lord Belborough unveils to them a Dutch organ which plays the music for the six o'-clock dance.
