1901.  Ludlow Brownell, in Everybody’s Mag., 107/2. The government is now at work on a seismic survey of the empire, and will publish as soon as possible a map, colored variously according to quakiness, dark for the most unsteady parts, and light for the parts that quake least.

1902.  Chattanooga News., 31 March, 7/5.

Of the ping pong patrons ponging at the pinging board.
