V.Founding and casting relate to forming parts of machinery by pouring melted metal into moulds, the force of gravity alone being sufficient to press or shape it into even complicated forms. As a process for shaping such metal as is not injured by the high degree of heat required in melting, moulding is the cheapest and most expeditious of all means, even for forms of regular outline, while the importance of moulding in producing irregular forms is such that without this process the whole system of machine construction would have to be changed. Founding operations are divided into two classes, known technically as green sand moulding, and loam or dry sand moulding; the first, when patterns or duplicates are used to form the moulds, and the second, when the moulds are built by hand without the aid of complete patterns. Founding involves a knowledge of mixing and melting metals such as are used in machine construction, the preparing and setting of cores for the internal displacement of the metal, cooling and shrinking strains, chills, and many other things that are more or less special, and can only be learned and understood from actual observation and practice.

FORE:"Rot!" Lawrence cried. "I've got some news for you. Prout has been with me and has left a letter in my possession. What do you think of that?"Here was something to go upon. Beyond doubt that gas had been used lately. Prout made a careful examination of the burners, sniffing and blowing at all of them. He found out one thing, only the burners in the hall and the bedroom where the murdered man had been found had been used for a long time. In a bedroom at the top of the house was a paraffin lamp with quite a new wick in it. With a stump of pencil Prout made a rapid calculation on the wall-paper.

FORE:We have said that Protagoras was a partisan of Nomos, or convention, against Nature. That was the conservative side of his character. Still, Nomos was not with him what it had been with the older Greeks, an immutable tradition indistinguishable from physical law. It was a human creation, and represented the outcome of inherited experience, admitting always of change for the better. Hence the vast importance which he attributed to education. This, no doubt, was magnifying his own office, for the training of youth was his profession. But, unquestionably, the feelings of his more liberal contemporaries went with him. A generation before, Pindar had spoken scornfully of intellectual culture as a vain attempt to make up for the absence of genius which the gods alone could give. Yet Pindar himself was always careful to dwell on the services rendered by professional trainers to the93 victorious athletes whose praises he sang, and there was really no reason why genius and culture should be permanently dissociated. A Themistocles might decide offhand on the questions brought before him; a Pericles, dealing with much more complex interests, already needed a more careful preparation.

TWO:There is no use in entering upon detailed explanations of what a learner has before him. Shafts are seen wherever there is machinery; it is easy to see the extent to which they are employed to transmit power, and the usual manner of arranging them. Various text-books afford data for determining the amount of torsional strain that shafts of a given diameter will bear; explain that their capacity to resist torsional strain is as the cube of the diameter, and that the deflection from transverse strains is so many degrees; with many other matters that are highly useful and proper to know. I will therefore not devote any space to these things here, but notice some of the more obscure conditions that pertain to shafts, such as are demonstrated by practical experience rather than deduced from mathematical data. What is said will apply especially to what is called line-shafting for conveying and distributing power in machine-shops and other manufacturing establishments. The following propositions in reference to shafts will assist in understanding what is to follow:Into the thousands their altimeter swung its indicator.

ONE:To learn to chip and file is indispensable, if for no other purpose, to be able to judge of the proficiency of others or to instruct them. Chipping and filing are purely matters of hand skill, tedious to learn, but when once acquired, are never forgotten. The use of a file is an interesting problem to study, and one of no little intricacy; in filing across a surface one inch wide, with a file twelve inches long, the pressure required at each end to guide it level may change at each stroke from nothing to twenty pounds or more; the nice sense of feeling which determines this is a matter of habit acquired by long practice. It is a wonder indeed that true surfaces can be made with a file, or even that a file can be used at all, except for rough work.

Injure or make useless roads or telegraphic instruments.It remains for us to glance at the controversy which has long been carried on respecting the true position of the Sophists in Greek life and thought. We have already alluded to the by no means favourable judgment passed on them by some among their contemporaries. Socrates condemned them severely,H but only because they received payment for their lessons; and the sentiment was probably echoed by many who had neither his disinterestedness nor his frugality. To make profit by intellectual work was not unusual in Greece. Pheidias sold his statues; Pindar spent his life writing for money; Simonides and Sophocles were charged with showing too great eagerness in the pursuit of gain.75 But a mans conversation with his friends had always been gratuitous, and the novel idea of charging a high fee for it excited considerable offence. Socrates called it prostitutionthe sale of that which should be the free gift of lovewithout perhaps sufficiently considering that the same privilege had formerly been purchased with a more dishonourable price. He also considered that a freeman was degraded by placing himself at the beck and call of another, although it would appear that the Sophists chose their own time for lecturing, and were certainly not more slaves than a sculptor or poet who had received an order to execute. It was also argued that any one who really succeeded in improving the104 community benefited so much by the result that it was unfair on his part to demand any additional remuneration. Suppose a popular preacher were to come over from New York to England, star about among the principal cities, charging a high price for admission to his sermons, and finally return home in possession of a handsome fortune, we can well imagine that sarcasms at the expense of such profitable piety would not be wanting. This hypothetical case will help us to understand how many an honest Athenian must have felt towards the showy colonial strangers who were making such a lucrative business of teaching moderation and justice. Plato, speaking for his master but not from his masters standpoint, raised an entirely different objection. He saw no reason why the Sophists should not sell their wisdom if they had any wisdom to sell. But this was precisely what he denied. He submitted their pretensions to a searching cross-examination, and, as he considered, convicted them of being worthless pretenders. There was a certain unfairness about this method, for neither his own positive teaching nor that of Socrates could have stood before a similar test, as Aristotle speedily demonstrated in the next generation. He was, in fact, only doing for Protagoras and Gorgias what they had done for early Greek speculation, and what every school habitually does for its predecessors. It had yet to be learned that this dissolving dialectic constitutes the very law of philosophical progress. The discovery was made by Hegel, and it is to him that the Sophists owe their rehabilitation in modern times. His lectures on the History of Philosophy contain much that was afterwards urged by Grote on the same side. Five years before the appearance of Grotes famous sixty-seventh chapter, Lewes had also published a vindication of the Sophists, possibly suggested by Hegels work, which he had certainly consulted when preparing his own History. There is, however, this great difference, that while the two English critics endeavour to minimise the105 sceptical, innovating tendency of the Sophists, it is, contrariwise, brought into exaggerated prominence by the German philosopher. We have just remarked that the final dissolution of Sophisticism was brought about by the separate development given to each of the various tendencies which it temporarily combined. Now, each of our three apologists has taken up one of these tendencies, and treated it as constituting the whole movement under discussion. To Hegel, the Sophists are chiefly subjective idealists. To Lewes, they are rhetoricians like Isocrates. To Grote, they are, what in truth the Sophists of the Roman empire were, teachers representing the standard opinions of their age. Lewes and Grote are both particularly anxious to prove that the original Sophists did not corrupt Greek morality. Thus much has been conceded by contemporary German criticism, and is no more than was observed by Plato long ago. Grote further asserts that the implied corruption of morality is an illusion, and that at the end of the Peloponnesian war the Athenians were no worse than their forefathers who fought at Marathon. His opinion is shared by so accomplished a scholar as Prof. Jowett;76 but here he has the combined authority of Thucydides, Aristophanes, and Plato against him. We have, however, examined this question already, and need not return to it. Whether any of the Sophists themselves can be proved to have taught immoral doctrines is another moot point. Grote defends them all, Polus and Thrasymachus included. Here, also, we have expressed our dissent from the eminent historian, whom we can only suppose to have missed the whole point of Platos argument. Lewes takes different106 ground when he accuses Plato of misrepresenting his opponents. It is true that the Sophists cannot be heard in self-defence, but there is no internal improbability about the charges brought against them. The Greek rhetoricians are not accused of saying anything that has not been said again and again by their modern representatives. Whether the odium of such sentiments should attach itself to the whole class of Sophists is quite another question. Grote denies that they held any doctrine in common. The German critics, on the other hand, insist on treating them as a school with common principles and tendencies. Brandis calls them a number of men, gifted indeed, but not seekers after knowledge for its own sake, who made a trade of giving instruction as a means for the attainment of external and selfish ends, and of substituting mere technical proficiency for real science.77 If our account be the true one, this would apply to Gorgias and the younger rhetoricians alone. One does not precisely see what external or selfish ends were subserved by the physical philosophy which Prodicus and Hippias taught, nor why the comprehensive enquiries of Protagoras into the conditions of civilisation and the limits of human knowledge should be contemptuously flung aside because he made them the basis of an honourable profession. Zeller, in much the same strain, defines a Sophist as one who professes to be a teacher of wisdom, while his object is individual culture (die formelle und praktische Bildung des Subjekts) and not the scientific investigation of truth.78 We do not know whether Grote was content with an explanation which would only have required an unimportant modification of his own statements to agree precisely with them. It ought amply to have satisfied Lewes. For ourselves, we must confess to caring very little whether the Sophists investigated truth for its own sake or as a means to self-culture. We believe, and in the next chapter we hope107 to show, that Socrates, at any rate, did not treat knowledge apart from practice as an end in itself. But the history of philosophy is not concerned with such subtleties as these. Our contention is that the Stoic, Epicurean, and Sceptical schools may be traced back through Antisthenes and Aristippus to Hippias and Protagoras much more directly than to Socrates. If Zeller will grant this, then he can no longer treat Sophisticism as a mere solvent of the old physical philosophy. If he denies it, we can only appeal to his own history, which here, as well as in our discussions of early Greek thought, we have found more useful than any other work on the subject. Our obligations to Grote are of a more general character. We have learned from him to look at the Sophists without prejudice. But we think that he, too, underrates their far-reaching intellectual significance, while his defence of their moral orthodoxy seems, so far as certain members of the class are concerned, inconsistent with any belief in Platos historical fidelity. That the most eminent Sophists did nothing to corrupt Greek morality is now almost universally admitted. If we have succeeded in showing that they did not corrupt but fruitfully develop Greek philosophy, the purpose of this study will have been sufficiently fulfilled.Logical division is, however, a process not fully represented by any fixed and formal distribution of topics, nor yet is it equivalent to the arrangement of genera and species according to their natural affinities, as in the admirable systems of Jussieu and Cuvier. It is something much more flexible and subtle, a carrying down into the minutest detail, of that psychological law which requires, as a condition of perfect consciousness, that feelings, conceptions, judgments, and, generally speaking, all mental modes should be apprehended together with their contradictory opposites. Heracleitus had a dim perception of this truth when he taught the identity of antithetical couples, and it is more or less vividly illustrated by all Greek classic literature after him; but Socrates seems to have been the first who transformed it from a law of existence into a law of cognition; with him knowledge and ignorance, reason and passion, freedom and slavery, virtue, and vice, right and wrong (πολλ?ν ?νομ?των μορφ? μ?α) were apprehended in inseparable connexion, and were employed for mutual elucidation, not only in broad masses, but also through their last subdivisions, like the delicate adjustments of light and shade on a Venetian canvas. This method of classification by graduated descent and symmetrical contrast, like the whole dialectic system of which it forms a branch, is only suited to the mental phenomena for which it was originally devised; and Hegel committed a fatal error when he applied it to explain the order of external coexistence and succession. We have already touched on the essentially subjective character of the Socratic definition, and148 we shall presently have to make a similar restriction in dealing with Socratic induction. With regard to the question last considered, our limits will not permit us, nor, indeed, does it fall within the scope of our present study, to pursue a vein of reflection which was never fully worked out either by the Athenian philosophers or by their modern successors, at least not in its only legitimate direction.It will be well for an apprentice to begin at once, as soon as he commences a shop course, to note the manner of handling material, watching the operation of cranes, hoists, trucks, tackle, rollers; in short, everything that has to do with moving and handling. The machinery and appliances in ordinary use are simple enough in a mechanical sense, but the principles of handling material are by no means as plain or easy to understand. The diversity of practice seen in various plans of handling and lifting weights fully attests the last proposition, and it is questionable whether there is any other branch of mechanical engineering that is treated less in a scientific way than machinery of this class. I do not allude to the mechanism of cranes and other devices, which are usually well proportioned and generally well arranged, but to the adaptation of such machinery with reference to special or local conditions. There are certain inherent difficulties that have to be encountered in the construction and operation of machinery, for lifting and handling, that are peculiar to it as a class; among these difficulties is the transmission of power to movable mechanism, the intermittent and irregular application of power, severe strains, also the liability to accidents and breakage from such machinery being controlled by the judgment of attendants.As I went a patrol marched outreinforcements had again come from Tongreswhose task was to clear the district of the enemy. The patrol consisted of six Death-head hussars, about forty bicyclists, and the rest infantry, altogether about four hundred men, who were able to keep together, because the hussars and the cyclists proceeded very slowly and cautiously in the direction of Lanaeken. I went with them, chatting with one of the officers. As soon as they had got to the road, the greatest caution188 was observed. The hussars went in front, followed by some of the infantry, all in loose formation, continually looking about in all directions, with the finger at the cock of the rifle.
