There was just as much groaning and straining as ever, but it was not so loud or squeaky in tone; and when the ship quivered she did not jar stiffly, like a poker hit on the floor, but gave with a supple little waggle, like a perfectly balanced golf-club. "We have made a most amazing discovery," said the stringers, one after another. "A discovery that entirely changes the situation. We have found, for the first time in the history of ship-building, that the inward pull of the deck-beams and the outward thrust of the frames locks us, as it were, more closely in our places, and enables us to endure a strain which is entirely without parallel in the records of marine architecture." The Steam turned a laugh quickly into a roar up the fog-horn. "What massive intellects you great stringers have," he said softly, when he had finished. "We also," began the deck-beams, "are discoverers and geniuses. We are of opinion that the support of the hold-pillars materially helps us. We find that we lock up on them when we are subjected to a heavy and singular weight of sea above." Here the _Dimbula_ shot down a hollow, lying almost on her side--righting at the bottom with a wrench and a spasm. "In these cases--are you aware of this, Steam?--the plating at the bows, and particularly at the stern--we would also mention the floors beneath us--help _us_ to resist any tendency to spring." The frames spoke, in the solemn, awed voice which people use when they have just come across something entirely new for the very first time. "I'm only a poor puffy little flutterer," said the Steam, "but I have to stand a good deal of pressure in my business. It's all tremendously interesting. Tell us some more. You fellows are so strong." "Watch us and you'll see," said the bow-plates, proudly. "Ready, behind there! Here's the Father and Mother of Waves coming! Sit tight, rivets all!" A great sluicing comber thundered by, but through the scuffle and confusion the Steam could hear the low, quick cries of the ironwork as the various strains took them--cries like these: "Easy, now--easy! _Now_ push for all your strength! Hold out! Give a fraction! Holdup! Pull in! Shove crossways! Mind the strain at the ends! Grip, now! Bite tight! Let the water get away from under--and there she goes!" The wave raced off into the darkness, shouting, "Not bad, that, if it's your first run!" and the drenched and ducked ship throbbed to the beat of the engines inside her. All three cylinders were white with the salt spray that had come down through the engine-room hatch; there was white fur on the canvas-bound steam-pipes, and even the bright-work deep below was speckled and soiled; but the cylinders had learned to make the most of steam that was half water, and were pounding along cheerfully. "How's the noblest outcome of human ingenuity hitting it?" said the Steam, as he whirled through the engine-room.
