WHEN SEEN.
There seems to be no definite rule as to the circumstances under which the Fairies are to be seen. A person whose eye has been touched with Fairy water can see them whenever they are present; the seer, possessed of second sight, often saw them when others did not; and on nights on which the shï-en is open the chance passer-by sees them rejoicing in their underground dwellings. A favourite time for their encounters with men seems to be the dusk and wild stormy nights of mist and driving rain, when the streams are swollen and ‘the roar of the torrent is heard on the hill.’ They are also apt to appear when spoken of and when a desire is expressed for their assistance; when proper precautions are omitted and those whose weakness and helplessness call for watchfulness and care, are neglected; when their power is contemned and when a sordid and churlish spirit is entertained. Often, without fault or effort, in places the most unexpected, mortals have been startled by their appearance, cries, or music.
