The electric “eye” latest addition to the cl an of the" “mechanical man” has just gone to work in the Holland vehicular tunnel under the. Hudson River, New York State. The robot’s job is to count the motor cars as they enter the tunnel. A light throws a beam upon a small window in the floor. As the motor car passes ‘through) the light it interrupts the beam, and a photo-electric cell inside the window responds by_ actuating an electric relay. This, in turn, operates a number-recording machine. Stop that cough. Where others fail 101 gives relief always. Only 2/6 and wonderfully effective. You’ll need it. Obtainable only at Ivan D. Bramwell’s Pharmacy, O'ladstnne Road and Derby Street.
