From the diary kept by Salem judge Samuel Sewall on May 20, 1713:

The rain hindered my return. Got to Brother's at Salem about 7:00 and lodged there. By this means I was not entangled with the riot committed that night in Boston by 200 people or more, breaking open Arthur Mason's warehouse in the Common, thinking to find corn there; wounded the Lieutenant Governor and Mr. Newton's son;…Were provoked by Captain Belchar's sending Indian corn to Curasso. The selectmen desired him not to send it; he told them, the hardest fend off! If they stopped his vessel, he would hinder the coming in of three times as much.
