In 1828, the temperance movement in Upper Canada got its start in Delta with a 4 hour sermon delivered on June 10, 1828, by Dr. Peter Schofield, an eminent medical doctor, distressed by the impact of drunkenness on society. Dr. Schofield delivered the sermon in the Old Stone Mill, a highlight of which was his rather vivid description of death by ″spontaneous combustion.″ He noted that "″it is well authenticated, that many habitual drinkers of ardent spirits are brought to their end by what is called spontaneous combustion″" and then went on to describe in some detail an event he’d witnessed.
