Teachers shock students at George Washington U. Washington, D.C., Aug. 2. Public speaking students at G.W. U. are only too well acquainted with the shocking machine, invented by Dr. Willard Hayes Yeager, Head of the department, to take the "ahs" "ers" and "ums" out of their diction. He is shown putting on the shocker to Jane Hampton, 17. When the student makes a mistake the professor at the other end of the room, notifies her by a gentle electric shock.
