Description

The harbor of Antwerp, which, excepting those of London and Liverpool, is the largest in Europe, has been improved wonderfully during the last decade. Before 1870 it was inferior to the harbor at Havre, but now it far surpasses the same. The river Scheldt, which is about 1, 500 ft. wide, was badgered out up to the vertical walls of the basin, so that the largest ships can land at the docks. The river was deepened by the use of caissons, in the lower parts of which the workmen operated in compressed air.
