_363. Chalk-back Day._--At Diss, Norfolk, it is customary for the
juvenile populace, on the Thursday before the third Friday in September
(on which latter day a fair and "session" for hiring servants are held),
to mark and disfigure each other's dress with white chalk, pleading a
prescriptive right to be mischievous on "chalk-back day." Does such a
practice exist elsewhere, and what is its origin?
