Photograph of general view of the Forth Bridge under construction. We have here a view taken late in the evening, which accounts for the smoothness of the water and the depth of the shadows. This view is chiefly remarkable for effect, much detail at the base of the cantilevers being lost. The picture embraces the whole of bridge up to date, north of south cantilever and on a considerable scale.

(This is the Forth (Rail) Bridge, not to be confused with the Forth Road Bridge.)
