The Class Day tradition of smoking clay “peace pipes” before smashing them on the Lone Pine stump began in the 1880s. It ended in 1992 because the tradition was seen as offensive to Native American students, who explained that the pipes were considered sacred objects in their culture. In 1993 the tradition was revived, somewhat, with students drinking a toast from clay mugs before smashing them at the base of the Lone Pine. Several students suffered injuries and required stitches when they were bombarded with shards of the clay cups. Nowadays, students simply hold a candlelit vigil with no pipes, mugs or smashing of any kind.
