In the 1770s, before Boone became an international celebrity, someone discovered a message on the bark of a beech tree that stood on the banks of a small tributary of the Watauga River in Tennessee. It read: “D. Boon Cilled a Bar on tree in the Year 1760.”
Over the centuries, many other versions of this carving have appeared on trees in North Carolina, Tennessee, Kentucky, and Missouri. Hunters did often leave such graffiti. But did Daniel Boone carve these words?
Maybe. But Boone, a fairly literate man, always spelled his name with an e on the end. The mystery remains.

If you "tree" an animal you're hunting, that means it has climbed a tree--and the implication is that it cannot escape then. Unless you're a poor shot.
