"It isn't distressingly calm now," said the extra strong frames - they were called web-frames - in the engine-room. "There's an upward thrust that we don't understand, and there's a twist that is very bad for our brackets and diamond- plates, and there's a sort of west-northwesterly pull, that follows the twist, which seriously annoys us. We mention this because we happened to cost a good deal of money, and we feel sure that the owner would not approve of our being treated in this frivolous way." I'm afraid the matter is out of owner's hands for the present," said the Steam, slipping into the condenser. "You're left to your own devices till the weather betters." "I wouldn't mind the weather," said a flat bass voice below; "it's this confounded cargo that's breaking my heart. I'm the garboard-strake, and I'm twice as thick as most of the others, and I ought to know something." The garboard-strake is the lowest plate in the bottom of a ship, and the Dimbula's garboardstrake was nearly three-quarters of an inch mild steel. "The sea pushes me up in a way I should never have expected," the strake grunted, "and the cargo pushes me down, and, between the two, I don't know what I'm supposed to do." "When in doubt, hold on," rumbled the Steam, making head in the boilers. "Yes; but there's only dark, and cold, and hurry, down here; and how do I know whether the other plates are doing their duty? Those bulwark-plates up above, I've heard, ain't more than five-sixteenths of an inch thick -scandalous, I call it." "I agree with you," said a huge web-frame, by the main cargo-hatch. He was deeper and thicker than all the others, and curved half-way across the ship in the shape of half an arch, to support the deck where deck-beams would have been in the way of cargo coming up and down. "I work entirely unsupported, and I observe that I am the sole strength of this vessel, so far as my vision extends. The responsibility, I assure you, is enormous. I believe the money-value of the cargo is over one hundred and fifty thousand pounds. Think of that!" "And every pound of it is dependent on my personal exertions." Here spoke a sea-valve that communicated directly with the water outside, and was seated not very far from the garboard-strake. "I rejoice to think that I am a Prince-Hyde Valve, with best Para rubber facings. Five patents cover me - I mention this without pride - five separate and several patents, each one finer than the other. At present I am screwed fast. Should I open, you would immediately be swamped. This is incontrovertible!" Patent things always use the longest words they can. It is a trick that they pick up from their inventors.
