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.
