There are 31 floating elevators in the port of New York, which are towed alongside of grain ships in order to fill in bulk. The grain is simply pumped from the capacious bins of the elevator to the hold of the ship.
The large stationary grain elevators are used as much for storage as for loading vessels. The number of stationary elevators in the port of New York is 22, and the total storage capacity of this port is 26,000,000 bushels.
Some idea of the quantity of grain stored in one of these elevators may be gained from the fact that when the elevators of the New York Central Railroad Company, at Sixtieth Street and the North River, were burned, the loss on the grain alone amounted to at least $75,000. The elevators had a total capacity of 2,300,000 bushels, and contained only 100,000 bushels at the time of the fire. Only one elevator was rebuilt.
The transfer capacity at the port of New York, or the rate at which grain ships can be loaded, is 458,000 bushels per hour.
Another type of vessel is the fruit steamship. There are about 90 in the tropical fruit trade between the United States, West Indies, and Central America. Bananas form the great bulk of the trade; cocoa-nuts, oranges, pineapples, and other fruits make up the balance of the cargoes. The principal fruit ports in the United States, besides New York, are Boston, Philadelphia, Baltimore, and New Orleans. The steamships are built expressly for the fruit trade, and are all, or nearly so, under the Norwegian and English flags, the Norwegian ships predominating. The hull is of steel lined with wood; the space between the steel plates (or outer skin of the vessel) and the wood is filled in with charcoal, which makes the ship a huge floating refrigerator. The vessels are provided with all the latest improvements in motive power, including triple-expansion engines and steam steering-gear. Some of the best ships devoted exclusively to the fruit trade have twin screws, and have accommodation for from 10 to 12 saloon passengers. Their average speed is from 11 to 13 knots. Many of the ships have their engines and boilers further aft than is the case in ordinary freighters.
Unloading a Banana Steamship.
Fruit steamships have three decks, all open, with a space of about two inches between each of the deck planks. This arrangement assures a free circulation of air at all times, and thus the fruit is preserved from heating and decay. These ships carry from 15,000 to 25,000 bunches of bananas, each bunch averaging in weight from 60 to 80 pounds, but some bunches have been found to weigh over 200 pounds. The fruit is “stowed” by an experienced stevedore, who devotes himself exclusively to the fruit trade. The bunches are placed on end along the decks, until all the space is filled; then a second and a third tier of bunches are laid flat, one over the other, in a manner that allows plenty of ventilation. Great care is taken to prevent the fruit from contact with salt-water, which causes the black spots frequently seen on bananas. After the vessels discharge the fruit they return in ballast for another cargo. The bulk of the crop is shipped during the five months from February to August. At the expiration of the season about one-third of the fruit vessels return to tropical ports and continue in the trade between there and the United States fruit ports during the winter. The other ships return to Europe with a grain cargo, and are chartered for general freight until the next fruit season.
Besides these vessels already mentioned, there are also three or four regular steamship lines which are largely engaged in the tropical fruit trade. The principal lines are the Atlas line, the Pacific Mail, the Anchor line, and the Honduras & Central American line. The vessels of the Atlas line are fitted with the most modern appliances for the preservation of the fruit. All these lines have excellent passenger accommodation, and carry a general cargo as well.
The total receipts of bananas at all United States ports in 1890 was 13,284,756 bunches, New York alone receiving 5,433,295 bunches of the fruit. The principal ports of shipments were Jamaica, 2,108,975 bunches; Baracoa, 1,478,596 bunches; Port Limon, 547,976 bunches; Honduras, 205,290 bunches; and other ports, 125,000 bunches.
