Motor-Vessels of 17,000 tons, a floating dock that can lift a ship of 17,000 tons, a floating-crane than can hoist a burden of 80 tons! These and other marvels of man's boundless invention the casual stroller on the waterfront accepts calmly as routine developments in the modern scheme of things, and he gives more time to watching the noisy play of seagulls or to the hopeful angling of small boys for sprats. Yet what a story of human endeavour and triumph is here! The sea pushed far back from the old shore-lines—huge stores and wharves built firmly on wide reclamations—and well-organised trade with the Old World and the New—great ships working to time-tables planned months ahead.
