I continue to review letters sent back and forth between Sunderland, UK to Ontario, Canada written by George Bell to his son Richard Bell. In one letter dated Oct. 1852, Richard pleads with his father back in Sunderland, "Dear Father for the comfort of home as well as preserving My Life Let Me know you have Signed the temperance Pledge". Could someone explain which temperance movement this was, what 'signing the temperance Pledge' meant and any other information you might have? Thanks, Susan.
