• LARGEST RADIO TUBE •
The 500-kilowatt transmitting tube, shown in the picture at the right, was on exhibition at the London exposition commemorating the 100th anniversary of the discovery of magnetic induction by Michael Faraday—for whom the farad is named. All electrical and radio development since then has been based on his work. General J. C. Smuts, president of the British Association and noted scientist, who opened the exposition, is at the left.

The speaker unit at the right is the biggest cone yet produced. Speech from this may be heard over a distance of three miles. # (Keystone Views)
