Machines are composed of parts connected together by rigid and movable joints; rigid joints are necessary because of the expense, and in most cases the impossibility, of constructing framing and other fixed detail in one piece.

TWO:But a profounder analysis of experience is necessary before we can come to the real roots of Platos scheme. It must be remembered that our philosopher was a revolutionist of the most thorough-going description, that he objected not to this or that constitution of his time, but to all existing consti254tutions whatever. Now, every great revolutionary movement, if in some respects an advance and an evolution, is in other respects a retrogression and a dissolution. When the most complex forms of political association are broken up, the older or subordinate forms suddenly acquire new life and meaning. What is true of practice is true also of speculation. Having broken away from the most advanced civilisation, Plato was thrown back on the spontaneous organisation of industry, on the army, the school, the family, the savage tribe, and even the herd of cattle, for types of social union. It was by taking some hints from each of these minor aggregates that he succeeded in building up his ideal polity, which, notwithstanding its supposed simplicity and consistency, is one of the most heterogeneous ever framed. The principles on which it rests are not really carried out to their logical consequences; they interfere with and supplement one another. The restriction of political power to a single class is avowedly based on the necessity for a division of labour. One man, we are told, can only do one thing well. But Plato should have seen that the producer is not for that reason to be made a monopolist; and that, to borrow his own favourite example, shoes are properly manufactured because the shoemaker is kept in order by the competition of his rivals and by the freedom of the consumer to purchase wherever he pleases. Athenian democracy, so far from contradicting the lessons of political economy, was, in truth, their logical application to government. The people did not really govern themselves, nor do they in any modern democracy, but they listened to different proposals, just as they might choose among different articles in a shop or different tenders for building a house, accepted the most suitable, and then left it to be carried out by their trusted agents.

THREE:Thus Maitrank chuckled over his invitation. He was going to take his vengeance for the trick played on him in his own good time. He had purposely kept out of the way of the Countess. He set the cables in motion, and after a due response or two he was closeted with the head of, a smart firm of lawyers in Ely Place.From this it may be seen that there must occur a great loss of power in operating on large pieces, for whatever force is absorbed by inertia has no effect on the underside. By watching a smith using a hand hammer it will be seen that whenever a piece operated upon is heavier than the hammer employed, but little if any effect is produced on the anvil or bottom surface, nor is this loss of effect the only one. The expense of heating, which generally exceeds that of shaping forgings, is directly as the amount of shaping that may be done at each heat; and consequently, if the two sides of a piece, instead of one, can be equally acted upon, one-half the heating will be saved.

THREE:(1.) Why are shaping machines better adapted than planing machines for planing slots, key-ways, and so on?(2.) What objects are gained by a quick return motion of the cutter bar of shaping machines?
THREE:"All right, sir."
THREE:A great share of the handling about an engineering establishment is avoided, if material can be stored and received on a higher level than the working floors; if, for instance, coal, iron, and sand is received from railway cars at an elevation sufficient to allow it to be deposited where it is stored by gravity, it is equivalent to saving the power and expense required to raise the material to such a height, or move it and pile it up, which amounts to the same thing in the end. It is not proposed to follow the details [74] of shop arrangement, farther than to furnish a clue to some of the general principles that should be regarded in devising plans of arrangement. Such principles are much more to be relied upon than even experience in suggesting the arrangement of shops, because all experience must be gained in connection with special local conditions, which often warp and prejudice the judgment, and lead to error in forming plans under circumstances different from those where the experience was gained.

THREE:It may be useless or even wrong to institute invidious comparisons between different callings which are all useful and necessary, and the matter is not introduced here with any view of exalting the engineering profession; it is for some reasons regretted that the subject is alluded to at all, but there is too much to be gained by an apprentice having a pride and love for his calling to pass over the matter of its dignity as a pursuit without calling attention to it. The gauntlet has been thrown down and comparison provoked by the unfair and unreasonable place that the politician, the metaphysician, and the moral philosopher have in the past assigned to the sciences and constructive arts. Poetry, metaphysics, mythology, war, and superstition have in their time engrossed the literature of the world, and formed the subject of what was alone considered education.After determining the ultimate objects of an improvement, and laying down the general principles which should be followed in the preparation of a design, there is nothing connected with constructive engineering that can be more nearly brought within general rules than arranging details. I am well aware of how far this statement is at variance with popular opinion among mechanics, and of the very thorough knowledge of machine application and machine operation required in making designs, and mean that there are certain principles and rules which may determine the arrangement and distribution of material, the position and relation of moving parts, bearings, and so on, and that a machine may be built up with no more risk of mistakes than in erecting a permanent structure.
