ARI SHAPIRO, HOST:

The border between France and Belgium was recently redrawn, but not because of a political dispute. Instead, it was a farmer. A big stone on his land was apparently bothering him, so he dug it up and dumped it about 7 1/2 feet away in the forest.

AILSA CHANG, HOST:

The stone, it turns out, is a border marker that marks the line between France and Belgium. And by moving it, the farmer inadvertently made Belgium a little bit bigger and France that much smaller. A history buff out for a walk in the woods spotted that the stone was out of place.

SHAPIRO: The mayor of the Belgian village Erquelinnes, about 40 miles south of Brussels, was delighted.

SHAPIRO: David Lavaux told a French newspaper he was happy his town was bigger. But the mayor of the neighboring French town didn't agree.

SHAPIRO: The mayor of the French border city, Aurelie Welonek, said she trusted that her Belgian colleague would do what is necessary to have the farmer move the boundary stone back.

WELONEK: (Non-English language spoken).

CHANG: The stone is one of many placed some 200 years ago to mark the border between France and Belgium. The local Belgian authorities plan to ask the farmer to put the stone back. If he doesn't, they might have to summon a Franco-Belgian border commission, which last met in 1930. Let's hope it doesn't come to that. But until the stone moves, the relationship between these two countries might be a little rocky.
