Many thanks to Mary Jane Sterling for bringing this problem to my attention.

In the British Museum an ancient document was discovered bearing the following instructions, presented here in modern language:

"Start from the crossing of King's Road and Queen's Road. Go north on King's Road and find first a pine tree, then a maple. Return to the crossing. West on Queen's Road is an elm tree and east on Queen's Road is a spruce. The intersection of the spruce-pine line and the elm-maple line is one magic point. The intersection of the elm-pine line and the maple-spruce line is a second magic point. The emperor's jewels are buried at the point where the line joining the two magic points crosses the Queen's Road."

After much searching, a modern search party found the location of the Queen's Road and the stumps of the elm and the spruce trees. But the King's Road had long since been covered by a parking lot, obliterating the location of the pine and maple trees. They regretfully gave up all hope of locating the buried treasure.

The day after the treasure hunters left the area, a local farmer went to the exact location of the treasure and dug up the jewels. How did he know where to dig?
