The clipper ship was the ocean greyhound of the Fifties. Her lines were those of a racer, her towering masts and broad expanse of canvas gave her the benefit of every breeze. She carried only the better class of freight in addition to her passengers, and it was not until some time after steamships had become an established fact that the passengers abandoned the clippers to the freight traffic.
For a time the sailing vessels held their own as freight carriers, but the improvements in steamships of recent years have robbed them of the bulk of their trade. They still hold their own for long sea voyages. There is a limit to the use of steam, and it is reached when the distance to be travelled makes the cost of coal and the space it occupies greater than the value of the cargo will warrant. Until some new motive power replaces steam, or steam is produced by the use of petroleum or other concentrated fuel, the clipper ship still has an occupation, and the hearts of all old-time skippers will be gladdened by the sight of her white wings upon the seas.
In 1850 a 1,400-ton sailing vessel was considered a big ship, but some of the new British four-masted steel ships sailing between Europe and America carry from 5,000 to 6,000 tons of cargo.
Great as have been the changes in ocean transportation, still greater changes are pending. The transatlantic business shows the most marked changes. From the old time packetship to the early type of steamship was but the first step. Faster vessels were built, and the space devoted to cargo was encroached upon by enormous engines and boilers, by big coal bunkers, and by large saloons and an increased number of state-rooms. The hulls changed from the bulging sides of the first types to the narrow, racing pattern of to-day. Speed and the arrangements for the comfort of a large list of passengers robbed the vessels of their freight capacity, and now the freight of an ocean greyhound is a secondary consideration. This necessitated the creation of a distinct class, known as the freighter.
The first railway cars having compartments for passengers, baggage, and freight were changed to express trains, where speed and comfort are the first considerations, and freight trains, where carrying capacity is the main object. In just the same manner, and for the same reasons, the ocean traffic is undergoing changes. The day cannot be far distant when the passenger ships will take only passengers, mails, specie, and express packages. The best-informed nautical men to-day declare that the progress of the last five years, remarkable as it has been, is but a circumstance compared with the possibilities of the future.
