Triple-screw propellers have since then been introduced in some of the greater ships, and the record speed has been cut down to the four days and ten hours of the Lusitania in 1908 and the four days, six hours and forty-one minutes of the Mauretania in 1910. The Titanic was not built especially for speed, but in every other way she was the master product of the shipbuilders' art.
At Hankow I embarked on the China Merchants' steamer Kweili, the only triple-screw steamer on the River, and four days later, on February 21st, I landed at Ichang, the most inland port on the Yangtse yet reached by steam.
The reciprocating engines drove the wing-propellers and the turbine a mid-propeller, making her a triple-screw vessel. To drive these engines she had 29 enormous boilers and 159 furnaces. Three elliptical funnels, 24 feet 6 inches in the widest diameter, took away smoke and water gases; the fourth one was a dummy for ventilation.
How wonderful is the contrast between the twentieth century, steel, triple-screw, 25,000-ton, electric-lighted, 25-knot steamship, and Winthrop's little "Blessing of the Bay," or Fulton's "Clermont," or even the ships of the Collins line floating palaces as they were called at the time!
She was a twelve-hundred-ton, triple-screw, turbine-driven boat, and, thanks to the space-economy of the new system, her builders had been able to stow away fifteen thousand horse-power in her engine-room, and this when fully developed gave a speed in smooth water of thirty-five knots or a little over forty statute miles an hour.
