"A tumult, riot, and mob exist on the Pennsylvania Railroad at East Liberty and in the Twelfth Ward of Pittsburgh. Large assemblages of people are upon the railroad and the movement of freight trains either east or west is prevented by intimidation and violence, molesting and obstructing the engineers and other employés of the railroad company in the discharge of their duties. As the sheriff of the county, I have endeavored to suppress the riot, but have not the adequate means at my command to do so, and I therefore request you to exercise your authority in calling out the military to suppress the same."
