David Gardner Affidavit: The gentleman who had invited me to the demonstration mentioned a contrivance that Dr Moray had also invented with which he could pick up sounds without them being broadcast from a radio sending station. He said that he had heard a demonstration of this device.

I asked if I might hear it also; he called Dr Moray over and asked if I might see a demonstration of the "sound pickup device", and I was granted the privilege.

There was an old radio box of conventional design with two headphones plugged into the box. Dr Moray tuned the device by turning the knob in front. He handed me one set of headphones and one set to my nephew Mr. Clark Gardner; he then arranged for three people to walk out of the house into the street and carry on a conversation to which we were tuned.

I was sure I was listening to these three men. I remember distinctly it was raining at the time and I could hear the patter of the rain on the pavement as they walked.

I remember them saying they had better hurry back into the house lest they get wet.

In the course of their return, I wondered if I might hear other people talking, and despite the advice of Dr Moray not to fool around with the tuning device, I moved the knob slowly and heard very distinctly the sounds of a railroad station: the whistle of a train, and a porter or the station master at his station saying, "All aboard". The nearest station to the receiving set would have been a minimum of 5 miles.

I know that the people on the street had no transmitting device or any other instrument with them. They would not believe me when I told them what I had heard, but they said I was repeating their conversation.
