The Duchess met the public during a walkabout at Duchy College

Charles met farmers and agriculture students at Duchy College at Stoke Climsland to discuss how best to grow and sell produce.

Then the couple travelled across the border into Devon to visit the offices of the Tavistock Times.

For his final visit, the prince went to Runnage Farm in Postbridge.

'She seemed nice'

While at Duchy College, Camilla was shown around the site and saw 60 children from Stoke Climsland Primary School taking part in outdoor educational and sports activities with the college students.

She was also shown around the equestrian unit and saw a performance of a ridden quadrille. After meeting Camilla, Ryan Brown, nine, said it was exciting to speak to her.

"She said `Are you having fun?' and I said, `Yes'," he said. "She seemed nice."

Camilla was shown around the college's riding stables where students are taught equine and business management. Equine centre manager Alison Abbey said it was an honour to meet her.

Phil Le Grice, director of learning and research at the college, said he was delighted the Prince had come to visit.

He said: "We were having a discussion with the prince about everything from what we do here, to growing and selling, and also how to market the business."

As they left, Charles and Camilla stopped to speak to some of the hundreds of flag-waving children who lined the road to the college to wave goodbye.

Their visit to Tavistock helped to celebrate the 150th anniversaries of The Tavistock Times Gazette, The Cornish Times, and the Cornish and Devon Post.

And despite strong winds and heavy, driving rain, the prince was given a demonstration by four apprentices of the Moor Skills Group, who are learning hedging and stone-walling.
