On the morning of November 18, 1755, an earthquake shock Boston． John Winthrop, a professor at Harvard College, felt the quake and awoke. “I rose”, Winthrop wrote, “and lighted a candle, looked at my watch, and found it to be 15minutes after four.” John Winthrop hurried downstairs to the grandfather clock．It had stopped three minutes before, at 4:12．Except for stopping the clock, the quake had only thrown a key from the mantel（壁炉台）to the floor．
