But when the power it gave out was compared with that of a good ordinary steam-engine, the verdict as to consumption of fuel was against the new rotary engine. Nevertheless, the enthusiastic projector, "tho' vanquished he would argue still," insisted that the merits of his contrivance would sooner or later cause it to be a most formidable rival to the crank steam-engines.
It had the effect of introducing among the higher order of artists habits of nice and accurate workmanship in executing delicate pieces of machinery; and the same combination of mechanical powers which made the steel spider crawl, the duck quack, or waved the tiny rod of the magician, contributed in future years to purposes of higher import, the wheels and pinions, which in these automata almost eluded the human senses by their minuteness, reappearing in modern times in the stupendous mechanism of our self-acting lathes, spinning-mules, and steam-engines.
The large and bustling family of the sawyers, both top and bottom, he has utterly banished from their ancient haunts. 'There would be needed a million and a half of them to take the places of 11,199 steam-engines, of 314,774 horse-power, that are devastating our forests. An equal number is replaced by the 16,559 water-wheels, of 326,728 horse-power, engaged in the same field of havoc.
Any school-boy can tell you, if you give him the dimensions of the Great Pyramid and state thirty-three thousand pounds one foot high in a minute as the conventional horse-power, how many hours it would take a pony-team picked out of the hundreds of thousands of steam-engines on the two continents to raise it.
I used often to wonder why boys wanted all these things. Now I know, because I asked Dick and he said, "You see, Aunt Woggles, I use them for other things." I am not sure that most of us don't do the same thing with many of our most cherished possessions in life. As regards steam-engines Zerlina lays down a distinct law.
Then came the brilliant discoveries of Faraday, Ampere, etc., demonstrating the relations between electricity and magnetism, and immediately following them a multitude of patents for electro-motors, and wild dreams of superseding steam-engines by magneto-electric machinery.
Yet as there were some subjects which the Greeks and Romans seemed to exhaust, some fields of labor and thought in which they never have been and perhaps never will be surpassed, so some future age may direct its energies into channels that are as unknown to us as clocks and steam-engines were to the Greeks.
Darwin, but I can no more believe that all this has come about without design on the part of the orchid, and a gradual perception of the advantages it is able to take over the bee, and a righteous determination to enjoy them, than I can believe that a mousetrap or a steam-engine is the result of the accumulation of blind minute fortuitous variations in a creature called man, which creature has never wanted either mousetraps or steam-engines, but has had a sort of promiscuous tendency to make them, and was benefited by making them, so that those of the race who had a tendency to make them survived and left issue, which issue would thus naturally tend to make more mousetraps and more steam-engines.
The man who deals in steam-engines, and warps and woofs, is naturally alarmed by Peep- of-Day Boys, and nocturnal Carders; his object is to buy and sell as quickly and quietly as he can, and he will naturally bear high taxes and rivalry in England, or emigrate to any part of the Continent, or to America, rather than plunge into the tumult of Irish politics and passions.
You do not see her broad-cloth, or her soft fabrics, or her steam-engines, but you see the broad shoulder of her sons and the soft cheeks of her daughters in vast states whose names you are utterly ignorant of; and as for the exportation of her products to foreign lands, just come with me on board this ocean steamship "Samaria", and look at them.
