The Shade Tree

Villagers like to come to rest and cool down in the shade of a huge, old tree. But when a young traveler decides to join them one day, a rich man on whose land the tree stands demands they leave because he owns the tree and therefore its shade. Thinking fast, the traveler strikes a deal: one that will enable him to outsmart the rich man--and ensure that the villagers will always have access to the shade tree's shade, wherever it may fall.
