Wireless telephone at White House

In 1919, President Wilson used a radio telephone set up on the south portico of the White House to direct the maneuvers of a dozen army airplanes flying over the Potomac river several miles away. His telephoned directions went direct to the flight commander in the air. The instrument was similar to those used by American aviators in France in the latter part of World War I. Col. C. C. Culver actively developed the equipment. He began the project in Aug 1910. No new invention was needed, only adaptation and adjustment of existing techniques. By Aug 1916, he was able to send a radio telegraph signal from a plane. Enlisting expert help from the telephone companies, by Oct 1917, voice messages could be send between a plane and the ground. The system was put into service for military wartime use.«

At Sunday School they were tea...

At Sunday School they were teaching how God created everything, including human beings. Little Johnny seemed especially intent when they told him how Eve was created out of one of Adam's ribs.
Later in the week his mother noticed him lying down as though he were ill, and she said, 'Johnny, what is the matter?'
Little Johnny responded, 'I have pain in my side. I think I'm going to have a wife.'
