The National Trust is seeking to promote the countryside by offering jars of fresh air to people living and working in cities.
It is sending the containers - which have been exposed to the unpolluted rural atmosphere and then sealed - in a bid to promote its special offer next weekend (March 20th and 21st) when all its properties will be open to visitors for free.
The Trust said its research had shown that for stressed-out city workers, the thing most likely to help them relax and unwind was seeing the sea (72 per cent), followed by a walk in the countryside.

who have not done so before may wish to visit their nearest Go Outdoor store to get some walking boots
One of the places where the air was bottled was at Townend near Troutbeck in the Lake District, once the home of Beatrix Potter.
Those looking to enjoy a Potter-related trip could also enjoy walking the wooded area of Claife Heights, a part of the Lake District close to another of her homes at Far Sawrey which inspired much of her writing.
