The National Trust in Britain, together with similar voluntary organization, plays an increasingly important part in the preservation for public enjoyment of the best that is left unspoiled of the British countryside. Although the Trust has received practical and moral support from the government, it is not a rich government, supported by public taxes. It is a voluntary association of people who care for the unspoiled countryside and the ancient sites to preserve them for the permanent enjoyment of the public. It is a charity which depends for its existence on voluntary support from members of the public. It has 160,000 members in England, Wales and Northern Ireland who pay a small subscription each year, and its primary duties are to protect for the nation places of great natural beauty and places of historical interest and preserve them from the dangers of modem development and extinction.
The attention of the public was First drawn to the dangers threatening the great old houses and castles of Britain by the late Lord Lothian, who in 1935 said that, as a result of taxation and estate duty, most of these ancient houses were under sentence of death. When he died he left his great seventh century house and all its contents to the Trust together with 4, S00-acre park and estate surrounding it. This gift attracted wide publicity and it started the Trust"s "Country House Scheme". Under the scheme, with cooperation of the government and thanks to the generosity of the general public about one hundred and fifty of these old houses, together with often very valuable contents. Whenever possible, the Trust seeks to maintain continuity and to preserve these as living realities rather than as dead museums. It is the view of the Trust that the families who give them to the nation and whose ancestors created them make the best possible curators.
In addition to country houses and open spaces the Trust now owns some examples of ancient wind and water mills, gardens, Roman antiquities, farms and small villages, as well as complete villages. In these villages no one is allowed to build, develop or disturb the old village environment and all houses maintain their original sixteen-century style. The public has free access to these areas and is only asked to respect the peace, beauty and wildlife.
