By Killarney's lakes and fells,
Em'rald Isles and winding bays,
Mountain paths and woodland dells,
Mem'ry ever fondly strays.
Bounteous nature loves all lands,
Beauty wanders every-where,
Foot-prints leaves on many strands,
But her home is surely there.
Angels fold their wings and rest,
In that Eden of the West,
Beauty's home Killarney—
Ever fair Killarney
