Machinery can be divided into four classes, each constituting a division that is very clearly defined by functions performed, as follows:

ONE:They heard the strange, hollow sound again, seeming to come from the metal wall, but impossible to locate at once because of the echo.In constructing patterns where it is optional whether to employ cores or not, and in preparing drawings for castings which may have either a ribbed or a cored section, it is nearly always best to employ cores. The usual estimate of the difference between the cost of moulding rib and cored sections, as well as of skeleton and cored patterns, is wrong. The expense of cores is often balanced by the advantage of having an 'open mould,' that is accessible for repairs or facing, and by the greater durability and convenience of the solid patterns. Taking, for example, a column, or box frame for machinery, that might be made either with a rib or a cored section, it would at first thought seem that patterns for a cored casting would cost much more by reason of the core-boxes; but it must be remembered that in most patterns labour is the principal expense, and what is lost in the extra lumber required for a core-box or in making a solid pattern is in many cases more than represented in the greater amount of labour required to construct a rib pattern.

TWO:Alls well! he grinned as Dick looked back.
THREE:After considering by what agencies the seeds of religious belief were carried from place to place, we have to examine, what was even more important, the quality of the soil on which they fell. And here, to continue the metaphor, we shall find that the Roman plough had not only broken through the crust of particularist prejudice, but had turned up new social strata eminently fitted to receive and nourish the germs scattered over their surface by every breeze and every bird of passage, or planted and watered by a spiritual sowers hand. Along with the positive check of an established worship, the negative check of dissolving criticism had, to a great extent, disappeared with the destruction of the rgime which had been most favourable to its exercise during the early stages of progress. The old city aristocracies were not merely opposed on patriotic grounds to free-trade in religion, but, as the most educated and independent class in the community, they were the first to shake off supernatural beliefs of every kind. We have grown so accustomed to seeing those beliefs upheld by the partisans of political privilege and attacked in the name of democratic principles, that we are apt to forget how very modern is the association of free-thought with the supremacy of numbers. It only dates from the French Revolution, and even now it is far from obtaining everywhere. Athens was the most perfectly organised democracy of antiquity, and in the course of this work we have repeatedly had occasion to observe how strong was the spirit of religious bigotry among the Athenian people. If we want rationalistic opinions we must go to the great nobles and their friends, to a Pericles, a Critias, or a Protagoras. There must also have been perfect intellectual liberty among205 the Roman nobles who took up Hellenic culture with such eagerness towards the middle of the second century B.C., and among those who, at a later period, listened with equanimity or approval to Caesars profession of Epicureanism in a crowded senatorial debate. It was as much in order that the De Rerum Natura should have been written by a member of this class as that the Aeneid should proceed from the pen of a modest provincial farmer. In positive knowledge, Virgil greatly excelled Lucretius, but his beliefs were inevitably determined by the traditions of his ignorant neighbours. When civil war, proscription, delation, and, perhaps more than any other cause, their own delirious extravagance, had wrought the ruin of the Roman aristocracy, their places were taken by respectable provincials who brought with them the convictions without the genius of the Mantuan poet; and thenceforward the tide of religious reaction never ceased rising until the Crusades, which were its supreme expression, unexpectedly brought about a first revival of Hellenic culture. On that occasion, also, the first symptoms of revolt manifested themselves among the nobles; taking the form of Gnosticism in the brilliant courts of Languedoc, and, at a later period, of Epicureanism in the Ghibelline circles of Florentine society; while, conversely, when the Ciompi or poorer artisans of Florence rose in revolt against the rich traders, one of the first demands made by the successful insurgents was, that a preaching friar should be sent to give them religious instruction. At a still later period, the same opposition of intellectual interests continues to be defined by the same social divisions. Two distinct currents of thought co-operated to bring about the Protestant Reformation. One, which was religious and reactionary, proceeded from the people. The other, which was secularising, scholarly, and scientific, represented the tendencies of the upper classes and of those who looked to them for encouragement and support. Throughout the sixteenth and seventeenth centuries, many noble names are to be found206 among the champions of reason; and while speculative liberty is associated with the ascendency of the aristocratic party, superstition and intolerance are associated with the triumph of the people, whether under the form of a democracy or of a levelling despotism. So, also, the great emancipating movement of the eighteenth century was fostered by the descendants of the Crusaders, and, until after the Revolution, met with no response among the bourgeoisie or the people; indeed the reaction in favour of supernaturalism was begun by a child of the people, Rousseau. All this, as we have already observed, has been reversed in more recent times; but the facts quoted are enough to prove how natural it was that in the ancient world decay of class privileges should be equivalent to a strengthening of the influences which made for supernaturalism and against enlightened criticism.CHAPTER XVII. MACHINERY FOR MOVING AND HANDLING MATERIAL.

THREE:There is a story that Plato used to thank the gods, in what some might consider a rather Pharisaic spirit, for having made him a human being instead of a brute, a man instead of a woman, and a Greek instead of a barbarian; but more than179 anything else for having permitted him to be born in the time of Socrates. It will be observed that all these blessings tended in one direction, the complete supremacy in his character of reason over impulse and sense. To assert, extend, and organise that supremacy was the object of his whole life. Such, indeed, had been the object of all his predecessors, and such, stated generally, has been always and everywhere the object of philosophy; but none had pursued it so consciously before, and none has proclaimed it so enthusiastically since then. Now, although Plato could not have done this without a far wider range of knowledge and experience than Socrates had possessed, it was only by virtue of the Socratic method that his other gifts and acquisitions could be turned to complete account; while, conversely, it was only when brought to bear upon these new materials that the full power of the method itself could be revealed. To be continually asking and answering questions; to elicit information from everybody on every subject worth knowing; and to elaborate the resulting mass of intellectual material into the most convenient form for practical application or for further transmission, was the secret of true wisdom with the sage of the market-place and the workshop. But the process of dialectic investigation as an end in itself, the intense personal interest of conversation with living men and women of all classes, the impatience for immediate and visible results, had gradually induced Socrates to restrict within far too narrow limits the sources whence his ideas were derived and the purposes to which they were applied. And the dialectic method itself could not but be checked in its internal development by this want of breadth and variety in the topics submitted to its grasp. Therefore the death of Socrates, however lamentable in its occasion, was an unmixed benefit to the cause for which he laboured, by arresting (as we must suppose it to have arrested) the popular and indiscriminate employment of his cross-examining method,180 liberating his ablest disciple from the ascendency of a revered master, and inducing him to reconsider the whole question of human knowledge and action from a remoter point of view. For, be it observed that Plato did not begin where Socrates had left off; he went back to the germinal point of the whole system, and proceeded to reconstruct it on new lines of his own. The loss of those whom we love habitually leads our thoughts back to the time of our first acquaintance with them, or, if these are ascertainable, to the circumstances of their early life. In this manner Plato seems to have been at first occupied exclusively with the starting-point of his friends philosophy, and we know, from the narrative given in the Apologia, under what form he came to conceive it. We have attempted to show that the account alluded to cannot be entirely historical. Nevertheless it seems sufficiently clear that Socrates began with a conviction of his own ignorance, and that his efforts to improve others were prefaced by the extraction of a similar confession of ignorance on their part. It is also certain that through life he regarded the causes of physical phenomena as placed beyond the reach of human reason and reserved by the gods for their own exclusive cognisance, pointing, by way of proof, to the notorious differences of opinion prevalent among those who had meddled with such matters. Thus, his scepticism worked in two directions, but on the one side it was only provisional and on the other it was only partial. Plato began by combining the two. He maintained that human nescience is universal and necessary; that the gods had reserved all knowledge for themselves; and that the only wisdom left for men is a consciousness of their absolute ignorance. The Socratic starting-point gave the centre of his agnostic circle; the Socratic theology gave the distance at which it was described. Here we have to note two thingsfirst, the breadth of generalisation which distinguishes the disciple from the master; and, secondly, the symptoms of a strong181 religious reaction against Greek humanism. Even before the end of the Peloponnesian War, evidence of this reaction had appeared, and the Bacchae of Euripides bears striking testimony to its gloomy and fanatical character. The last agony of Athens, the collapse of her power, and the subsequent period of oligarchic terrorism, must have given a stimulus to superstition like that which quite recently afflicted France with an epidemic of apparitions and pilgrimages almost too childish for belief. Plato followed the general movement, although on a much higher plane. While looking down with undisguised contempt on the immoral idolatry of his countrymen, he was equally opposed to the irreligion of the New Learning, and, had an opportunity been given him, he would, like the Reformers of the sixteenth century, have put down both with impartial severity. Nor was this the only analogy between his position and that of a Luther or a Calvin. Like them, and indeed like all great religious teachers, he exalted the Creator by enlarging on the nothingness of the creature; just as Christianity exhibits the holiness of God in contrast and correlation with the sinfulness of unregenerate hearts; just as to Pindar mans life seemed but the fleeting shadow in a dream when compared with the beauty and strength and immortality of the Olympian divinities; so also did Plato deepen the gloom of human ignorance that he might bring out in dazzling relief the fulness of that knowledge which he had been taught to prize as a supreme ideal, but which, for that very reason, seemed proper to the highest existences alone. And we shall presently see how Plato also discovered a principle in man by virtue of which he could claim kindred with the supernatural, and elaborated a scheme of intellectual mediation by which the fallen spirit could be regenerated and made a partaker in the kingdom of speculative truth.

THREE:I have in this way imperfectly indicated a methodical plan of generating a design, as far as words alone will serve, beginning with certain premises based upon a particular work to be performed, and then proceeding to consider in consecutive order the general character of the machine, mode of operation, movements and adjustments, general arrangement, strains, special arrangement, and proportions.

We have assumed in our last remark that it is possible to discover some sort of chronological order in the Platonic Dialogues, and to trace a certain progressive modification in the general tenor of their teaching from first to last. But here also the positive evidence is very scanty, and a variety of conflicting theories have been propounded by eminent scholars. Where so much is left to conjecture, the best that can be said for any hypothesis is that it explains the facts according to known laws of thought. It will be for the reader to judge whether our own attempt to trace the gradual evolution of Platos system satisfies this condition. In making it we shall take as a basis the arrangement adopted by Prof. Jowett, with some reservations hereafter to be specified.The hydroplane cant get there in time! shouted Larry."For heaven's sake come here at once. Don't wait, but----"We have considered the Aristotelian philosophy in relation to the great concrete interests of life, morals, politics, literature, and science. We have now to ask what it has to tell us about the deepest and gravest problems of any, the first principles of Being and Knowing, God and the soul, spirit and matter, metaphysics, psychology, and logic. We saw that very high claims were advanced on behalf of Aristotle in respect to his treatment of these topics; and had we begun with them, we should only have been following the usual example of his expositors. We have, however, preferred keeping them to the last, that our readers might acquire some familiarity with the Aristotelian method, by seeing it applied to subjects where the results were immediately intelligible, and could be tested by an appeal to the experience of twenty-two centuries. We know that there are some who will demur to this proceeding, who will say that Aristotle the metaphysician stands on quite different ground from Aristotle the man of science, because in the one capacity he had, and in the other capacity he had not, sufficient facts to warrant an authoritative conclusion. They will say, with Prof. St. George Mivart, that in accumulating natural knowledge mens minds have become deadened to spiritual truth; or with Mr. Edwin Wallace, that the questions opened by Aristotle have not yet been closed, and that we may with advantage begin331 our study of them under his guidance. We, on the other hand, will endeavour to show that there is a unity of composition running through the Stagirites entire labours, that they everywhere manifest the same excellences and defects, which are those of an anatomising, critical, descriptive, classificatory genius; that his most important conclusions, however great their historical interest, are without any positive or even educational value for us, being almost entirely based on false physical assumptions; that his ontology and psychology are not what his admirers suppose them to be; and that his logic, though meriting our gratitude, is far too confused and incomplete to throw any light on the questions raised by modern thinkers.
