Barton granted his neighbor, Mullins, the right to graze her cattle on Barton's land. Identify the type of property interest Mullins has in Barton's land and explain how such interests are created.

Barton has granted Mullins a profit à prendre which means the right to remove the produce from another's land. It may arise by prescription, but if it comes about through an act of the parties, it must be created with all the formalities accorded the grant of an estate in real property. Unless the right is clearly designated as exclusive, Barton is entitled to exercise the right as well.
