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! Time has made commonplace the proportions of the "Great Eastern," the marine marvel not only of her age, but of the forty years that succeeded her breaking-up as impracticable on account of size. She was 19,000 tons, 690 feet long, and built with both paddle-wheels and a screw. The "Celtic" is 700 feet long, 20,000 tons, with twin screws. The one was too big to be commercially valuable, the other has held the record for size only for a year, being already outclassed by the Northern Pacific 25,000-ton monsters. That one was a failure, the other a success, is almost wholly due to the improvements in engines, which effect economy of space both in the engine-room and in the coal bunkers. It is, by the way, rather a curious illustration of the growing luxury of life, and of ocean travel, that the first voyage of this enormous ship was made as a yacht, carrying a party of pleasure-seekers, with not a pound of cargo, through the show places of the Mediterranean. It will be interesting to chronicle here some of the characteristics of the most modern of ocean steamships, and to show by the use of some figures, the enormous proportions to which their business has attained. For this purpose it will be necessary to use figures drawn from the records of foreign lines, and from such vessels as the "Deutschland" and the "Celtic," although the purpose of this book is to tell the story of the American merchant marine. But the figures given will be approximately correct for the great American ships now building, while there are not at present in service any American passenger ships which are fairly representative of the twentieth century liner.
