What does Rock Chalk Jayhawk Mean?

According to the Kansas Media Guide, ‘Rock Chalk Jayhawk’ was started in early 1900 by a chemistry professor named E.H.S. Bailey. This was his attempt to cheer on his science club, but it was over heard and adopted to the sports team. It pays tribute to the very rich deposits of chalky limestone in the area. Besides that, the most significant purpose of the chant was to make you wonder. People who hear it are always puzzled. Notoriety works!
