She had her choice, and she took it. The end came when, presuming on her lighter draught, she tried to draw away northward over a friendly shoal. The shell that arrived by way of the Chief Engineer's cabin was some five inches in diameter, with a practice, not a bursting, charge. It had been intended to cross her bows, and that was why it knocked the framed portrait of the Chief Engineer's wife - and she was a very pretty girl - on to the floor, splintered his wash-hand stand, crossed the alleyway into the engine-room, and striking on a grating, dropped directly in front of the forward engine, where it burst, neatly fracturing both the bolts that held the connecting-rod to the forward crank. What follows is worth consideration. The forward engine had no more work to do. Its released piston-rod, therefore, drove up fiercely, with nothing to check it, and started most of the nuts of the cylinder-cover. It came down again, the full weight of the steam behind it, and the foot of the disconnected connecting-rod, useless as the leg of a man with a sprained ankle, flung out to the right and struck the starboard, or right-hand, cast-iron supporting-column of the forward engine, cracking it clean through about six inches above the base, and wedging the upper portion outwards three inches towards the ship's side. There the connecting-rod jammed. Meantime, the after-engine, being as yet unembarrassed, went on with its work, and in so doing brought round at its next revolution the crank of the forward engine, which smote the already jammed connecting-rod, bending it and therewith the piston-rod cross-head- the big cross-piece that slides up and down so smoothly.
