From a letter from Eugene Curry, 8th August, 1839: "...while some labourers were turning up the soil...directly between the above perforated rock and the Ath Fada or Lorgforde on the Slaney, they met with a great number of skeletons at from two to three feet below the surface, and among other things, they met with several curiously formed graves containing urns with burned and unburned bones."
