In the next few pages we take our readers on what we regard as a magical journey into the past. It begins at the right with one of the two frames of a stereopticon view, reproduced in its exact original size. The scene is a railway station at Leavenworth, Kansas, in 1867, and it is scarcely prepossessing. Even the planting of two girls in the foreground (an old ploy of our esteemed contemporary the National Geographic ) does little for the photograph. But that is the heart of the matter. Life lurks within the picture, waiting to be released. Turn the page and see what happens when one part of it is enlarged. Then open the double fold-out and look at a detail of that enlargement spread over four of our pages. Suddenly there is no end to what can be seen; you are right there, in a suspended moment, almost jostling against the everyday life of over a century ago.
