In some rural districts the custom still prevails of ?Thomasing? - that is, of collecting small sums of money or obtaining drink from the employers of labour on the 21st of December - ?St. Thomas's Day.? December 21st is still noted in London as that day when every one of the Common Council has to be either elected or re-elected, and the electors are wholly without restriction except as to age and sex. The aldermen and their officers are not elected on St. Thomas's Day.
