STATUES in the garden of Treasurer's House in York were today being treated for the effects of city pollution during two public demonstrations.

Members of the public will also get a chance to see conservation in action tomorrow and Thursday when further demonstrations take place at 12.30pm and 2pm daily.

The National Trust's specialist stone conservator, Trevor Proudfoot, was today using various poultices to remove atmospheric dust and grime and to strengthen the statues against further damage.

Mr Proudfoot said: "We tend to think that objects as solid as stone take care of themselves, but in fact they need as much care and attention as many of the items to be found inside an historic house.

"These 18th century sandstone statues in the picturesque garden here at Treasurer's House are no exception.

"We know they have been here for 100 years and city pollution and the weather have both taken their toll.

"I hope visitors will enjoy the chance to see the work in action each day and perhaps understand why we need their support to help pay for essential work like this."
