Read it through once

From Gibraltar, running along the coasts of Spain and France, Marseilles will be reached in three days. Here ample time will be given not only to look over the city, which was founded six hundred years before the Christian era, and its artificial port, the finest of the kind in the Mediterranean, but to visit Paris during the Great Exhibition; and the beautiful city of Lyons, lying intermediate, from the heights of which, on a clear day, Mont Blanc and the Alps can be distinctly seen. Passengers who may wish to extend the time at Paris can do so, and, passing down through Switzerland, rejoin the steamer at Genoa.
