Free Miners were granted a right to register to mine in the Forest of Dean under certain conditions. These included being a male twenty-one years old or more, born and living in the Hundred of St Briavels and having worked in a mine for a year and a day. The Gaveller, or the Deputy Gaveller, granted such rights on behalf of the Crown provided by those rules and regulations set in 1841. It is generally accepted now that the ancient rights of Free Miners were given to Forest Miners for their services to Edward I in 1296 for undermining the walls and defences of Berwick-on-Tweed during one of the sieges that befell it. Residents of the Hundred of St Briavels over 18 also have a right to graze sheep in the Forest in accordance with an agreement between the Forestry Commission and the Commoners Association.
