Vigilance committees used sketched hanging warnings to drive men out within hours

Evidence

At Alma and Fairplay vigilance committees have been lately formed, and when men act outrageously and make themselves generally obnoxious they receive a letter with a drawing of a tree, a man hanging from it, and a coffin below, on which is written “Forewarned.” They ”git” in a few hours. — Isabella L. Bird, A Lady’s Life in the Rocky Mountains, 198
