So it is thought that nothing is so unfavorable to the working of the wheels as light, heat, electricity, magnetism, and, generally, all the imponderable and uncatchable essences that float about in the air; and these, it is thought, are generated and diffused by these villanous newspapers. Certain kinds of books are also forbidden, as being electric conductors. Most of the books allowed in the city of Grindwell are so heavy, that they are thought to be usually non-conductors, and therefore quite safe in the hands of the people. It is at the city gates that most vigilance is required with regard to the prohibited articles. There the poor fellows who keep the gates have no rest night or day,--so many suspicious-looking boxes, bundles, bales, and barrels claim admittance. Quantities of articles are arrested and prevented from entering. Nothing that can in any way interfere with the great machine can come in. Newspapers and books from other countries are torn and burnt up. Speaking-trumpets, ear-trumpets, spectacles, microscopes, spy-glasses, telescopes, and, generally, all instruments and contrivances for extending the sphere of ordinary knowledge, are very narrowly examined before they are admitted. The only trumpets freely allowed are of a musical sort, fit to amuse the people,--the only spectacles, green goggles to keep out the glare of truth's sunshine,--the magnifying-glasses, those which exaggerate the proportions of the imperial governor of the machinery. All sorts of moral lightning-rods and telegraph-wires are arrested, and lie in great piles outside the city walls. But in spite of the utmost vigilance and care of the officers at the gates and the sentinels on the thick walls, dangerous articles and dangerous people will pass in. A man like Kossuth or Mazzini going through would produce such a current of the electric fluid, that the machine would be in great danger of combustion. Remonstrances were sometimes sent to neighboring cities, to the effect that they should keep their light and heat to themselves, and not be throwing such strong _reflections_ into the weak eyes of the Grindwellites, and putting in danger the governmental powder-magazine,--as the machine-offices were sometimes called. An inundation or bad harvest, producing a famine among the poor, causes great alarm, and the government officers have a time of it, running about distributing alms, or raising money to keep down the price of bread. Thousands of servants in livery, armed with terrific instruments for the destruction of life, are kept standing on and around the walls of the city, ready at a moment's notice to shoot down any one who makes any movement or demonstration in a direction contrary to the laws of the machine. And to support this great crowd of liveried lackeys, the people are squeezed like sponges, till they furnish the necessary money.
