Matt and Anita are in Herefordshire. Matt looks at the county's historic perry-making industry and helps out with the pear harvest. He starts out at Weston's, the cider makers, who are the world's biggest producers of perry. Then he travels to the 12th-century Hellen's Manor, where some of the rarest and oldest pear trees in the world are to be found. He gathers a sackful and heads to meet self-styled 'ciderologist' Gabe Wood, a man who likes cider but loves perry even more. Together they make perry the old-fashioned way - on a stone grinding wheel with lots of elbow grease. Anita is at a farm where time has stood still. She recounts the story of Birches Farm and farmer Alfred Price through the diaries he kept. She also visits the last traditional clog maker in Herefordshire to see clogs being made the time-honoured way. Joe Crowley is with PhD student Charlotte Selvey, who is using worms made of modelling clay to find out what birds are present in the county's ancient orchards. The birds leave beak impressions in the fake worms, which identifies them. Tom's looking at the appalling conditions endured by some workers on the high seas, conditions which many have described as slavery. And Adam is on the farm where they're harvesting bracken for fuel.
