These steamships are all supplied with triple expansion engines, and are capable of maintaining a speed of from 8 to 11 knots per hour on the small coal consumption of about 25 tons for each 24 hours. The Bayonne is the fastest; she made the trip from England to New York in 11 days, averaging 11.10 knots per hour. They average from 2,000 to 3,000 tons gross, and carry from 3,000 to 4,000 tons of cargo. Aft of the engine-room is the cabin and officers’ quarters, which are comfortable in every particular. The crew is located in the forecastle, as is usual on all vessels. The crew number about 30, all told.
Another type of steamship, which is an outcome of the tank idea, is the molasses ship. These have been used with success in carrying molasses in bulk between Havana and New York. The Circassian Prince is a notable instance of this type. The traffic in molasses is not very great at present, but when the trade increases tank steamships will, no doubt, be largely employed.
The loading of an ocean steamship is a sight well worth a visit to one of the city piers to witness. With the exception of the North German Lloyd, the Hamburg-American, the Netherlands, and the Thingvalla lines, whose piers are in Hoboken, and the Red Star Line, and some of the Inman vessels, in Jersey City, the great transatlantic steamships dock along the North River, from Canal Street up to Twenty-fourth Street. The length of the steamships, some of them being nearly 600 feet, make very long piers necessary. These piers on a sailing day present an animated scene. A long line of trucks, loaded with all sorts of merchandise, moves slowly down the pier, each truck delivering its packages opposite the particular hatchway down which they are to be lowered. The big ships load at four different hatchways at the same time. Steam-hoisting apparatus at each, and separate gangs of men, all, however, under the direction of one stevedore, load and stow the immense cargo in an incredibly short space of time.
All prominent lines handle their own freight, but some of the smaller lines give it out by contract to a stevedore, who employs his own men. About six gangs of twenty-five men each, and about twelve foremen and dock-clerks are employed. As many men are employed as can work to advantage. The day men are relieved by other gangs of men who work at night. In rush times a few men are added to each gang. From 10,000 to 100,000 packages constitute an ocean steamship’s cargo. The largest number of packages are carried at the season of the year when the Bordeaux fruit canning trade is on, and the proportion of small packages is increased. Some big packages, such as a street-car completely boxed, or a steam-launch enclosed in a case, require considerable power and much skill to load. Heavy machinery and enormous cases are lifted from the dock, swung over the open hatchway, and lowered to the cavernous depths as quickly and easily as though they weighed but a hundred pounds instead of several tons.
The stowing of the freight requires experience and judgment. The weight must be arranged so that the vessel stands upon an even keel, and she must not be down at the bow, or too low at the stern. Then the cargo must be stowed so that it will not shift. The importance of this is seen when the rolling and plunging of the ship in a heavy sea is considered. The cargo would not only be seriously injured if it tumbled about, but the vessel would be unmanageable. The stevedores and the ’longshoremen who attend to this work are experienced men, and the difficulty of loading ships with inexperienced men caused the owners of many steamships to permit them to remain idle at the time of the great London dock strikes.
Particular attention is paid to stowing the cargo of an ocean racer. Every package is fitted into place, so that the cargo will be a solid part of the vessel, and serve to ballast and trim her to the best advantage.[19]
The North German Lloyd line holds the record for rapid loading and unloading of cargo. The Eider arrived at 10 A.M., one day in January, 1890, and in twenty-nine hours her freight was discharged, and a full cargo, the mails, and her complement of passengers were on board, and the lines cast off for a return trip to Europe.
The ocean steamships are coaled at their docks. The barges containing the coal are towed alongside, on both sides of the vessel, and the work of coaling commences immediately after her arrival in port. It is hoisted up by iron buckets, coaling on both sides going on at the same time. It requires about four and a half days to coal one of the big greyhounds. There are eight coal barges employed in the work; each of these barges contains from 250 to 300 tons of coal. Some of the lines get their coal from Baltimore, and others from Norfolk. The coaling, as now conducted, is a tedious as well as a dirty process, and it is difficult to understand why lines have not adopted the elevator method which was tried on some of the naval and coastwise vessels some two years ago, and proved a success, both as to economy, rapidity, and cleanliness. The experiment showed that 500 tons of coal could be stowed away in the bunkers by chutes in one hour.
