Have you ever wondered why they cut a mules tail in “bells”?
Back in the day…..the Army used mules in service.
A green mule had its tail shaved. By the time the mule was broke to pack, a ‘bell’ was trimmed in the tail. Once broke to drive, a second bell was added below the first. Broke to ride, a third tassel was trimmed below the second.
Thus, a three-bell mule was a well-schooled animal.
This way, when looking at a corral full of unknown mules, it was easy to identify which one to select for the job at hand!
