Hence it became necessary to form a joint at the top of the piston-rod where it united with the cross head, so as to permit the cross head to preserve complete parallelism with the axle of the wheels with which it was in communication.
One of the engineers was doing his work in a peculiarly twisted way, like a man asleep caught between the rim of the wheel and the piston-rod covered with verdigris. Frederick descended on his ghastly tour down to the stokers, whom the catastrophe had surprised in the midst of their occupation. Some were still holding their shovels in their hands, though unable to lift them.
Who would have thought that such a fine, white, delicate hand could give you a squeeze like a piston-rod?" Spero looked wonderingly at his hands, and then dreamily said: "I am stronger than I thought." "I think so, too," said Coucou. "Only the count understands how to squeeze one's hand in that way. I almost forgot to ask you, vicomte, where you intend to take breakfast?"
After four hours of this furious work, the piston-rod suddenly slipped, and the piston rose with a jerk, knocking one or two men over into the engine-room. But when Mr. Wardrop declared that the piston had not split, they cheered, and thought nothing of their wounds; and the donkey-engine was hastily stopped; its boiler was nothing to tamper with.

At last, I thought as the Blue Dryad, for one second coiled close as a black silk cable, sprang out the next as straight and sharp as the piston-rod of an engine, this lump of feline vanity and conceit is done for, and I could not help thinking it will probably be my turn next!
The two men sprang into a posture of defence, which was lost as quickly as it was taken, one great arm shot out like a piston-rod; there was the sound of bare fists beating on naked flesh; there was an exultant indrawn gasp of savage pleasure and relief from the crowd, and the great fight had begun.
And he noted with further perplexity that the prodigious piston-rod not only moved with terrific speed, but in a strictly back-and-forth motion; its far end did not revolve. The agent seemed satisfied with it all. He turned about and walked so far as Smith could sense in the usual manner of earth's humans back to the dials again.
They removed two of the piston junk-ring studs, screwed in two strong iron eye-bolts by way of handles, doubled the wire-rope, and set half a dozen men to smite with an extemporised battering-ram at the end of the piston-rod, where it peered through the piston, while the donkey-engine hauled upwards on the piston itself.
The steam-engine itself, which supplies us with such unbounded power, owes its present perfection to this most admirable means of giving to metallic objects the most precise and perfect geometrical forms. How could we, for instance, have good steam-engines if we had not the means of boring out a true cylinder, or turning a true piston-rod, or planing a valve face?
