Visitors on the moving pavement, Paris, 1900.

Pasengers could travel at two speeds, fast or slow. 'Round the whole route...was placed a stationary platform. From this one stepped upon a narrow part..., which was moving slowly. Parallel...with this was a wider platform moving considerably faster; thus, with a step or two one found oneself proceeding, without further effort, at the rate of, perhaps, five miles an hour. If, again, one walked at an average pace on this swiftly moving platform, one found that the traffic in the street below was easily left behind. And a very novel and fascinating mode of proceeding this proved to be to many millions of visitors.' In the background is the Rue des Nations (Street of Nations).
