The next fixture he passed was a gas lamp in a glass chimney.
The men came out, one of them carrying a copper lamp with a glass chimney.
The glass chimney shattered; the flame shot high, then puffed out.
Specially designed glass chimneys protect the lights from the park winds.
The oil lamp was surrounded by a glass chimney with no ventilation from below.
He removed the glass chimney, turned up the wick, and tried to strike a match.
Cupping a hand over the far side of the glass chimney, he blew into the lamp.
He is sometimes credited with the addition of the glass chimney to the lamp.
Then he lit the lamp, let the flame grow and returned the glass chimney.
He didn't want to bang its fragile glass chimney in the dark!
