Let the reader compare a hammer with a wheel and axle, inclined plane, screw, or lever, as an agent for concentrating and applying power, noting the principles of its action first, and then considering its universal use, and he will conclude that, if there is a mechanical device that comprehends distinct principles, that device is the common hammer. It seems, indeed, to be one of those provisions to meet a human necessity, and without which mechanical industry could not be carried on. In the manipulation of nearly every kind of material, the hammer is continually necessary in order to exert a force beyond what the hands may do, unaided by mechanism to multiply their force. A carpenter in driving a spike requires a force of from one to two tons; a blacksmith requires a force of from five pounds to five tons to meet the requirements of his work; a stonemason applies a force of from one hundred to one thousand pounds in driving the edge of his tools; chipping, calking, in fact nearly all mechanical operations, consist more or less in blows, such blows being the application of accumulated force expended throughout a limited distance.

THREE:CHAPTER XXVII. COMPOUND HAMMERS.

THREE:Both slowly struggled back into consciousness in the fitful dreams of mediaeval sleep. Nature was represented by astrology with its fatalistic predetermination of events; idealism by the alchemical lore which was to give its possessor eternal youth and inexhaustible wealth. With the complete revival of classic literature and the temporary neutralisation of theology by internal discord, both sprang up again in glorious life, and produced the great art of the sixteenth century, the great science and philosophy of the seventeenth. Later on, becoming self-conscious, they divide, and their partisans draw off into two opposing armies, Rousseau against Voltaire, Herder against Kant, Goethe against Schiller, Hume against himself. Together they bring about the Revolution; but after marching hand in hand to the destruction of all existing institutions they again part company, and, putting on the frippery of a dead faith, confront one another, each with its own ritual, its own acolytes, its own intolerance, with feasts of Nature and goddesses of Reason, in mutual and murderous hostility. When the storm subsided, new lines of demarcation were laid down, and the cause of political liberty was dissociated from what seemed to be thoroughly discredited figments. Nevertheless, imaginative literature still preserves traces of the old conflict, and on examining the four greatest English novelists of the last fifty years we shall find that Dickens and Charlotte Bront, though personally most unlike, agree in representing the arbitrary, subjective, ideal side of life, the subjugation of things to self, not of self to things; he transfiguring them in the light of humour, fancy, sentiment; she transforming them by the alchemy of inward passion; while102 Thackeray and George Eliot represent the triumph of natural forces over rebellious individualities; the one writer depicting an often crude reality at odds with convention and conceit; while the other, possessing, if not an intrinsically greater genius, at least a higher philosophical culture, discloses to us the primordial necessities of existence, the pitiless conformations of circumstance, before which egoism, ignorance, illusion, and indecision must bow, or be crushed to pieces if they resist.

We update dependencies to keep things fresh.

TWO:Finishing as a process is a secondary and not always an essential one; many parts of machinery are ready for use when forged or cast and do not require fitting; yet a finishing shop must in many respects be considered the leading department of an engineering establishment. Plans, drawings and estimates are always based on finished work, and when the parts have accurate dimensions; hence designs, drawings and estimates may be said to pass through the fitting shop and follow back to the foundry and smith shop, so that finishing, although the last process in the order of the work, is the first one after the drawings in every other sense; even the dimensions in pattern-making which seems farthest removed from finishing, are based upon fitting dimensions, and to a great extent must be modified [119]by the conditions of finishing.
