Excerpt from The United States of America Through the Stereoscope: One Hundred Outlooks From Successive Positions in Different Parts of the World's Greatest RepublicThe difference between a mere picture and a stereo graph is probably clear to you now.It seems to some people too wonderful for belief that stereographs should give them the impression of every thing in the full size of the actual, existing world, yet this also is true. Look out through a window ten feet away at a man in the street beyond, how much space on the window-glass is actually occupied by his distant figure? The facts will surprise you. A visit ing card held in your own hand at arm's length would more than cover him from sight. That same small card might cover a tall building, or even hide a dis tant mountain, for a small thing near the eyes fills the same space as a much larger thing farther away. This fact of Optics has also to do with the service ren dered by stereographs, for the stereoscopic prints, when viewed through a stereoscope, become like so many windows through which you see the real things, full size, off at the distance where they actually were in fact, when confronted by the sensitized plates of the camera.About the PublisherForgotten Books publishes hundreds of thousands of rare and classic books.
