I fear golden apples will not be strewn on our paths, even though we are bound the furthest west. Fifteen days have we been out of sight of land; two days out from Queenstown we broke a piston-rod, which obliged us to lay to, in a fearfully rough sea, for five hours.
They had kept the hardest work to the last, as boys save Latin prose, and, worn though they were, Mr. Wardrop did not dare to give them rest. The piston-rod and connecting-rod were to be straightened, and this was a job for a regular dockyard with every appliance. They fell to it, cheered by a little chalk showing of work done and time consumed which Mr.
Yet upon the ear fell the rumble and clang of moving machinery, and the eye, piercing through the half-lights of the archway, caught indefinite glimpses of the pulsing mysteries of wheel and piston-rod that lay within the shadows. "He must be within," said Nanna, leading the way. "Don't stumble around like that. Here, take my hand."
Now I want to introduce you to a very old friend of mine, the Lord-Lieutenant of the county." The Turk was bustled off, a little unwillingly. Peter watched them with a smile. It was many months since he had felt so keen an interest in life. The coming of Bernadine had steadied his nerves. His gun had come to his shoulder like the piston-rod of an engine. His eye was clear, his nerve still.
We have just seen that the brachial muscle could at one time move the forearm and hand, but that when they are fixed it could then use the humerus as a lever and thereby lift the weight of the body. What should we think of a metal engine which could reverse its action so that it could act through its piston-rod at one time and through its cylinder at another?
There is apparently nothing simpler than the placing of the head of the piston-rod between two guide-pieces to keep it in line and give it bearing. Yet we have only to turn back a few years and see the elaborate and beautiful geometrical diagram contrived by Watt to produce the same simple effect, and known as a "parallel motion."
In these iron days of the dominance of steam, the crowning wrong that is wrought us of furnace and piston-rod lies in their annihilation of the steadfast mystery of the horizon, so that the imagination no longer begins to work at the point where vision ceases.
But some man picked out all these features of a complete mill and put them into proper relation; he adjusted shaft, boiler, and cogwheel, put water in the boiler and fire under it, let steam into the cylinders, and moved piston-rod, wheels, and saw.
He was going to forge and shrink a wrought-iron collar on the neck of the piston-rod where it joined the cross-head, and from the collar he would bolt a Y-shaped piece of iron whose lower arms should be bolted into the cross-head. If anything more were needed, they could use up the last of the boiler-plate. So the forges were lit again, and men burned their bodies, but hardly felt the pain.
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.
