New York's skyline by night is the most impressive sight of its kind in the world. The night 

 the Statue of Liberty was illuminated, at which time the above photograph was taken, the buildings 

 on Manhattan's shoreline stood out in brilliant array, a light in every window. The buildings 



slightly darker pieces inserted here and 

 there variously down to the base of the 

 flame, where the darkest of the tints 

 defined the lines of the bronze of the torch 

 against the glass of the flame. 



It took six hundred pieces of glass, each 

 about one ' inch square, to complete the 

 glass area of the torch. The glass is so 

 fixed to the ribs that any section may be 

 replaced at any time from the inside.

At the moment the statue was bathed in light Ruth Law, 

 the flyer, swept like a comet across the sky, two streams 

 of white magnesium flame trailing behind her aeroplane 



candlepower gas-filled electric lamps were 

 connected with a flasher. A flasher is 

 merely a rotating drum containing surface 

 projections which close the lamp circuits 

 every time they hit a stationary piece of 

 metal. The flasher connected with the 

 Statue of Liberty lights is not set to certain 

 revolutions, the experts preferring to allow 

 it to carry out the unsteady flicker and 

 blaze of the burning torch. The torch 



also contains 

 a lighthouse 

 lens, nine and
