Hallowe'en, or Hallow-Even, the evening of October 31st, which precedes November 1st, known as the festival of All Saints. On this evening witches and all sorts of mischievous spirits are supposed to be abroad. It was considered formerly quite as safe not to be caught out alone on Hallowe'en; and even now it is considered good manners, at least, for elderly people to stay in doors. The belief in spirits abroad has faded out, yet the many pranks still played on this evening indicate that unusual agencies are at work. Burns' Hallowe'en is a picture of the Scottish festivities held on this evening. See HOLIDAY; ALL SAINTS' DAY.
