In 1854 the Argo, a full-rigged iron ship of 1850 tons register, with plenty of canvas and fitted with an auxiliary engine and screw, made the passage from London to Melbourne in 64 days and home round Cape Horn in 63 days; and though she sailed during the greater portion of the voyage, using her engines only in calms and light winds, she was the first merchant vessel using steam-power to circumnavigate the globe. This voyage is peculiarly adapted to auxiliary steam vessels, as, by following the sailing-ship track, very few strong head winds are met, and of course the screw is of great assistance in light winds and calms.
The Argo was followed (1855–1856) by the Royal Charter, Istamboul, and Khersonese and other iron auxiliary "steam clippers," as they were called. These vessels carried as much canvas as the clipper ships, and were more expensive to handle and not much faster; the rivalry was therefore keen. The clippers still secured their full share of the cabin and steerage passengers, the mails and gold, and were by no means vanquished; indeed, the auxiliaries proved no more successful than the steamships, and brought much the same result to their owners.
It was not till after the close of the Crimean War in 1856, when the Peninsular & Oriental Steam Navigation Company extended their line to the Australian colonies, that the clipper ships began seriously to feel the competition of steam. From that time iron sailing vessels for this trade were
