In Pennsylvania, a massive boiler explosion in Philadelphia kills and injures dozens of saw mill workers.

At around 5:30 pm a boiler in the yard of a steam saw mill on Sansom Street, between 10th and 11th Streets, in Philadelphia exploded with spectacular effect.  The five story brick building housing the mill collapsed completely, burying most of it forty employees, many recent German immigrants. The surrounding area suffered significant but more minor damage.  At least twenty deaths were reported and twelve others were pulled from the rubble with mild to serious injuries. The cause of the disaster was unknown.  (By John Osborne)
