Chigley

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.

Farmer Bell makes his regular delivery of produce to the Chigley biscuit factory, and gets a tour of the factory from Mr Cresswell. They notice that a box of biscuits meant for delivery has been overlooked. As Trumpton is very congested at this time of day it is too late to take it by road to Wintelbury station, in time for the 5.23 train to London. Farmer Bell comes to the rescue by taking the box to the pottery where it is picked up by Lord Belborough in Bessie and taken to Treddles Wharf. Here it is transferred to Chippy Minton's truck which he drives off to Wintelbury. Mr Swallow then points out that as the timetable has recently been changed, the train doesn't leave until 5.43, and so they would have made it by road anyway !

The Mayor of Trumpton visits Lord Belborough and asks him for fund-raising ideas for the Old People's Holiday Fund. When Lord Belborough has to go to the Pottery he gives Winnie a ride on Bessie. Her balloon gives him an idea.

PC McGarry calls at the pottery to invite Mr Farthing to tea. Mr Farthing is sculpting in his garden but explains that there is not much demand for stone sculptures these days. PC McGarry then calls in at the Biscuit Factory where he tells Mr Cresswell that he has a clean and modern looking factory, but also points out that a fountain would look nice. Mr Cresswell asks Mr Farthing the Potter to make one. Lord Belborough picks up the block of stone from Treddles Wharf, Farmer Bell digs the foundations and Mr Clutterbuck builds the fountain's basin. Then at six o'clock one evening, when it is all finished, the Mayor of Trumpton unveils the fountain.

Mr Crockett delivers a lawnmower to Winkstead Hall, having just rebuilt the engine, and "sharpened her up". Lord Belborough starts the mower, which was still in gear, and it runs off and demolishes the garden wall and door. Lord Belborough phones Mr Clutterbuck the builder and asks him if he can rebuild the wall before the weekend, but Mr Clutterbuck is still awaiting delivery of a load of bricks, which are stuck at Treddles Wharf. Lord Belborough and Brackett steam of to the wharf in Bessie and collect the bricks. Bricklayers Cyril and Horrace are then able to rebuild the wall, while Chippy Minton and Nibbs make a new door. Mr Crockett repairs the mower, "using several completely new parts" and everything is ready in time for the six o'clock dance.

Roger Varley arrives at Winkstead Hall to help clean Bessie the steam engine and Binnie the pumping engine. Roger is cleaning Binnie when Brackett the butler comes in and says the water level in Winkstead Hall is very low. But the only way to pump the water is to burn the coal to get the pumping engine going, but there is no coal left. They ring up Mr Swallow at Treddles Wharf and ask for some coal. He tells them that they will have to pick it up. They set off in Bessie, pick up the coal at the wharf, and return to Winkstead Hall. With a new delivery of coal Binnie can pump again. The biscuit factory whistle blows and it is time for the six o'clock dance.
