rung daily at 8 p.m. for the Angelus, though it is popularly called the Curfew. Twice three tolls are rung for a male and thrice two for a female. An "invitation bell" is rung before funerals. No.4 was formerly rung at 11a.m. on Shrove Tuesday, and all the bells used to be rung for some days before Christmas.  It was also the custom here to ring a muffled peal at 3 p.m. on Good Friday. The treble and tenor were rung for a fire and No.3 was rung to summon the vestry meeting.

Windows. There are 12 stained glass windows inserted at intervals between 1848 and 1916, of which the best is the westernmost one in the north aisle, designed by Kempe and commemorating Canon W. F. W. Westbrooke, vicar from 1886-1916. The window in the tower was given by the "Maries" of Caistor in 1889.

The Gad Whip (Plate III). By the generosity of the descendants of the late Mr William Brooks of Fonaby and Hundon, the church now possesses a specimen of the whips used in the curious and probably unique custom connected with the observance of Palm Sunday in Caistor Church in bygone years. This whip is exhibited in a glass ease near the Lady Chapel and consists of a stock, six feet in length, and a lash of seven feet one inch. At the upper end of the stock, which is partly bound with hide, is a small purse, a replica of the original one made by the late Mrs Stephenson, daughter of Mr Brooks, in whose memory the whip was given by her daughters. This purse contained 30 silver coins (some say 24) one of which, a halfpenny of the reign of Edward II, may be seen near the whip. Also attached to the stock are three pieces of wych elm. There were supposed to be four of these, of differing length, a possible emblem of the Four Gospels.
There are many printed accounts of the peculiar ceremonv connected with this whip. The details of the custom seem briefly to have been as follows.
Every Palm Sunday, the tenant of certain lands in the parish of Broughton, belonging to the lord of the manor of Hundon, had to provide a whip of the type described above, and send a man with it to Caistor church. During the reading of the first Lesson at Mattins this man cracked the whip
