a table in which the 19 chief avenues of trade are analyzed, showing the

parts of Europe, and also an account of the contour of Europe from the
railroad man’s point of view, discussing the mountain ranges pierced by
tunnels and the passes over which lines have been carried wholly or
largely in the open.
