Work on an ocean steamship never ends, for no sooner does she reach her moorings in New York, Liverpool or Hamburg than preparations begin for the next voyage. Her decks are holystoned, sprinkled with sand and made beautifully clean; the outside of her hull, from deck to water line, is repainted and, if it be the end of a round trip or voyage, all the exterior paint work receives a new coat, while her sanitary and plumbing arrangements, her smokestacks, woodwork, spars and rigging are all carefully examined and overhauled. All this is done by the sailors under the direction of the boatswain, who reports each day to the officer on duty and receives instruction as to the work to be performed. Meanwhile an overhauling equally minute and thorough is going on in the engineer's department, which includes not only the engines and boilers, but also the electric-lighting plant of the ship. The work of this department, however, is so arduous while at sea that officers and men receive liberty for the entire time the ship remains in port, their places being taken by a special shore force which remains aboard until sailing day. One boiler is left untouched to supply power for the engines that work the electric and refrigerating apparatus, the pumps and the machinery used in shipping cargo, but all the others as soon as they have cooled are entered, examined and, if need be, repaired. Each tube, combustion chamber and furnace receives careful attention; cylinders, pistons, crankpins and crossheads are gone over one by one, while the engines are generally overhauled and all the arrangements of the fireroom inspected. Nor is the steward's department less busy while in port. All the bed and table linen used during the voyage, many thousands of pieces, is collected and sent to the company's laundry, after which all the staterooms are cleaned and put in order and the fresh supply of linen made ready for the coming voyage.
