A famous schoolmaster, descended from the Callaghan McCarthys of Canfie (Ardgroom District) was Stephen McCarthy, who taught in Ballycrovane Primary School, near the original Coastguard Station (now Murphy's house), and later as Principal Teacher in the old thatched-roofed Urhan School (this building now long gone) in the 1866s-1870s. He was known to all as "Master Mac". Money was very scarce in those days and there was no map available for the teaching of geography. But Master Mac was a firm believer in the old saying that necessity is the mother of invention. He sent one of his pupils over to William O'Dwyer's garden to pull up a big turnip. With a penknife, Master Mac cut out a map of the world on the turnip and began teaching his geography lesson. After a while there was a knock on the door. The Master went out to the porch to talk to the caller. While he was out, one of the pupils got hungry and began eating the turnip. When the Master returned after a quarter of an hour, the turnip was nowhere to be found. It was the first time that the world was eaten in 15 minutes flat !! ----- Riobard.
