Wizard and Mis Tricks

WONDERFUL CONTRIVANCE BROWN AND WHITE BEANS At the, top of a block of officos in Regent Street, London, a wizard has at his complete command a genie of infinite powers. Ho calls his slave “The Electric Eye.’’ It opens doors, turns lights off and on, sorts black beads from blue beads, and tells him. whether a beau is good to eat or not. The wizard is Mr Rex Horsfield, late consulting engineer to an electrical company in America. He is an Englishman, with an American sense of humour. He has been in England to per* suado business men and manufacturers to use the "Electric Eye" in the furtherance of their lawful occasions.

When he was called upon recently, writes an Evening News correspondent, Mr Horsfield pointed to the electric eye. “Blow' some smoko across it,” ho said. In the interests of science the visitor did so. A light changed from red to green and back again as the smoko faded.

“Just sensitivity,” said the wizard, “I am trying to get them to put the ‘Eye’ in factories and restaurants. The idea is that every time a workman or a waiter approaches a door he crosses the t, cam -_ a nd the door opens. You don’t even have to know “Sesame.” Then Mr Horsfield introduced his visitor to his favourite. It tells how many beans make five, spills the beans, and in fact, knows everything about beans.

“This is tho idea,” he said, “it has already been tested by one of the big gest canncrs in this country. "The photo-electric cell, which is the basis of the electric eye idea, is sensitive to the light reflection thrown off by any object. A white bean affects it in one way, a brown beau in another. White beans are good beans. Yory well. “Tons of beans are passed on an endless band through the ray. It is set to reject the brown beans. By means of a jet of compressed air which is only operated by the light reflection of 6 white bean,' tho white beans are shot off into a container. The others pass on into oblivion.”
