May 19, 1910: Hundreds of students at Valparaiso University rampage through the city, brawling with citizens armed with clubs and baseball bats. The students dragged Sam Ling from his Chinese laundry and beat him, tried to free prisoners in the County Jail and fought with police. Unfortunately, The Times’ wire story doesn’t provide the reason for the melee, nor can I find any further stories. An official history of the campus is curiously silent on the matter.
