Here is a piece of info on the inscription:
On a peninsula of Lough Erne stands Castle Caldwell, with the famous
"Fiddle Stone" at its gate. The inscription on the stone gives warning to

On firm land only exercise your skill
That you may play and safely drink your fill.
This was taken from _Of Irish Ways_ by Mary Murray Delaney on p.297.
