Take one of them when she is hiking along at 20 knots, rolling from 45 to 50 degrees, and just about filling the whale-boat swinging to the skid deck davits as she rolls! See one dive and take a sea over her fo'c's'le head and smash in her chart-house bulkhead maybe! Their outer skin is only 3/16 of an inch thick. See that thin skin give to the sea like a lace fan to a breeze! Watch the deck crawl till sometimes the deck-plates buckle up into V-shaped ridges! See them with the seas sloshing up their low freeboard and over their narrow decks, so that men have to make use of a sort of trolley line to get about. A man is aft and has to go forward, say. He hooks onto a rope loop, the same hanging from a fore-and-aft taut steel line about seven feet above deck, and when her stern rises he lifts his feet and shoots and fetches up Bam!--up against the fo'c's'le break. He is forward and wants to go aft--he hooks onto the loop, waits for her bow to rise, lets himself go and there he is--back to her skid deck. That sounds like rough work. Sometimes it gets rougher than that, and then you hear of the wireless operator who was held in his radio shack for forty hours. He got pretty hungry, but he preferred the hunger to coming out and being washed overboard. But let a machinist's mate tell you in his own way of the night he was standing a fire-room watch--this with all due respect to the chart-house bulkhead, the trolley line, the buckling decks, and the radio operator who was confined--this night he was on watch in the fire-room. Was it rough? He thought so. When he looked down at his feet, there were the fire-room deck-plates folding in and out like a concertina. Destroyer crews do not loaf overmuch around deck. They can't. They live below decks mostly, strapped in when it is rough to a stretch of canvas laced to four pieces of iron pipe, set on an angle down against the ship's sides, and called a bunk. Even strapped in so they are sometimes, when she has a good streak on, hove out into the passageways. It was a young doctor of the flotilla who said that, except for their broken arms and legs, his ship's crew were disgustingly healthy.
