Story about an encounter with a fairy while gathering plants for healing and accompanying song collected from Catrine Pearson [Catherine MacFarlane née MacPherson, Ceanntangabhal/Kentangaval, Barraigh/Isle of Barra]. The story tells how Niall Pearson of Bruarnis [Neil MacPherson, Bruairnis/Bruernish] was at Drollam [Drolum] cutting cairst-leanna or braonan-a-choin [cairt-leamhna or braonan-nan-con, tuberous bitter vetch or dog carmillion], which is good for diahorrea or tanning leather, and which can be found among heather roots and moss. He heard a fairy woman singing a song, while grinding her quern. The informant notes that if a thing is denied 'geasad' to the fairies, they will take it, but if it is consecrated to the Trinity or to Mary, they cannot and praise it.
