The following are suggested as subjects which may be studied in connection with lathes and turning: the rate of cutting movement on iron, steel, and brass; the relative speed of the belt cones, whether the changes are by a true ascending scale from the slowest; the rate of feed at different changes estimated like the threads of a screw at so many cuts per inch; the proportions of cone or step pulleys to insure a uniform belt tension, the theory of the following rest as employed in turning flexible pieces, the difference between having three or four bearing points for centre or following rests; the best means of testing the truth of a lathe. All these matters and many more are subjects not only of interest but of use in learning lathe manipulation, and their study will lead to a logical method of dealing with problems which will continually arise.

TWO: INTRODUCTIONTo the unskilled, or to those who do not take a comprehensive view of an engineering business as a whole, the finishing and fitting department seems to constitute the whole of machine manufacturean impression which a learner should guard against, because nothing but a true understanding of the importance and relations of the different divisions of an establishment can enable them to be thoroughly or easily learned.
FORE:The adaptation, endurance, and cost of machines in designing become resolved into problems of movements, the arrangement of parts, and proportions.
FORE:Still, it was just as well to be on the safe side. There must be no suspicion that there had been any foul play here.
FORE:A leading principle in machinery of transmission that more than any other furnishes data for strength and proper proportions is, that the stress upon the machinery, whatever it may be, is inverse as the speed at which it moves. For example, a belt two inches wide, moving one thousand feet a minute, will theoretically perform the same work that one ten inches wide will do, moving at a speed of two hundred feet a minute; or a shaft making two hundred revolutions a minute will transmit four times as much power as a shaft making but fifty revolutions in the same time, the torsional strain being the same in both cases.
FORE:The reformed system of education was to be not only moral and religious but also severely scientific. The place given to mathematics as the foundation of a right intellectual training is most remarkable, and shows how truly Plato apprehended the conditions under which knowledge is acquired and enlarged. Here, as in other respects, he is, more even than Aristotle, the precursor of Auguste Comte. He arranges the mathematical sciences, so far as they then existed, in their logical order; and his remarks on the most general ideas suggested by astronomy read like a divination of rational mechanics. That a recommendation of such studies should be put into the mouth of Socrates is a striking incongruity. The older Plato grew the farther he seems to have advanced from the humanist to the naturalistic point of view; and, had he been willing to confess it, Hippias and Prodicus were the teachers with whom he finally found himself most in sympathy.
FORE:Ghastly reminders of their former feasts.192At Cherath railway-carriages were lying in the road at the level-crossing of Vis-Lige line, farther on barbed-wire cut into pieces, felled trees, and so on. German soldiers had moved these things out of the way, and motor-cars could pass by again. In the village itself I saw a man, with a white armlet, posting up a bill, and as I had seen similar damp bills sticking on the walls in the other villages, I drew nearer to read it.
FORE:"Oh yes, it has been destroyed already a couple of times, but we shall teach them a lesson! Why did not the Belgians allow us to pass through their country? What can their little army do against us? As soon as a sufficient number have crossed we shall go for these forts, then on to Brussels, and within a fortnight we shall be in Paris. Lige we have taken already."
FORE:The sceptical philosophy, already advocated in the Middle Ages by John of Salisbury, was, like every other form of ancient thought, revived at the Renaissance, but only under419 the very superficial form which infers from the co-existence of many divergent opinions that none of them can be true. Even so, however, it led Montaigne to sounder notions of toleration and humanity than were entertained by any of his contemporaries. With Bacon, and still more with Descartes, it also appears as the necessary preparation for a remodelling of all belief; but the great dogmatic systems still exercised such a potent influence on both those thinkers that their professed demand for a new method merely leads up to an altered statement of the old unproved assumptions.Nor was this all. Thought, after having, as it would seem, wandered away from reality in search of empty abstractions, by the help of those very abstractions regained possession of concrete existence, and acquired a far fuller intelligence of its complex manifestations. For, each individual character is an assemblage of qualities, and can only be understood when those qualities, after having been separately studied, are finally recombined. Thus, biography is a very late production of literature, and although biographies are the favourite reading of those who most despise philosophy, they could never have been written without its help. Moreover, before characters can be described they must exist. Now, it is partly philosophy which calls character into existence by sedulous inculcation of self-knowledge and self-culture, by consolidating a mans individuality into something independent of circumstances, so that it comes to form, not a figure in bas-relief, but what sculptors call a figure in the round. Such was Socrates himself, and such were the figures which he taught Xenophon and Plato to recognise and portray. Character-drawing begins with them, and the Memorabilia in particular is the earliest attempt at a biographical analysis that we possess. From this to Plutarchs Lives there was still a long journey to be accomplished, but the interval between them is less considerable than that which divides Xenophon from his immediate predecessor, Thucydides. And when we remember how intimately the substance of Christian teaching is connected with the literary form of its first record, we shall still better appreciate the all-penetrating influence of Hellenic thought,158 vying, as it does, with the forces of nature in subtlety and universal diffusion.
FORE:The terrible thunder of the guns, of both besiegers and besieged, vibrated through the air. In the distance I noticed a couple of men, probably German soldiers, but a pontoon-bridge was nowhere to be seen. After a few minutes, however, I reached a spot where the Meuse makes a short curve, and had scarcely walked round it, when I saw, only a couple of hundred yards away, the bridge in question, across which a long train of vehicles was passing, loaded with victuals, hay, straw, etc."Now, look here, sister, I am a cousin of S?ur...."
FORE:Yet another step remained to take. Punishment must be transferred from a mans innocent children to the man himself in a future life. But the Olympian theology was, originally at least, powerless to effect this revolution. Its gods, being personifications of celestial phenomena, had nothing to do with the dark underworld whither men descended after death. There existed, however, side by side with the brilliant religion of courts and camps which Greek poetry has made so familiar to us, another religion more popular with simple country-folk,53 to whom war meant ruin, courts of justice a means invented by kings for exacting bribes, sea-voyages a senseless imprudence, chariot-racing a sinful waste of money, and beautiful women drones in the human hive, demons of extravagance invented by Zeus for the purpose of venting his spite against mankind. What interest could these poor people take in the resplendent guardians of their hereditary oppressors, in Hr and Athn, Apollo and Poseid?n, Artemis and Aphrodit? But they had other gods peculiar to themselves, whose worship was wrapped in mystery, partly that its objects need not be lured away by the attraction of richer offerings elsewhere, partly because the activity of these Chthonian deities, as they were called, was naturally associated with darkness and secresy. Presiding over birth and death, over seed-time and harvest and vintage, they personified the frost-bound sleep of vegetation in winter and its return from a dark underworld in spring. Out of their worship grew stories which told how Persephon, the fair daughter of Dmtr, or Mother Earth, was carried away by Pluto to reign with him over the shades below, but after long searching was restored to her mother for eight months in every year; and how Dionysus, the wine-god, was twice born, first from67 the earth burned up and fainting under the intolerable fire of a summer sky, respectively personified as Semel and her lover Zeus, then from the protecting mist wrapped round him by his divine father, of whom it formed a part. Dionysus, too, was subject to alternations of depression and triumph, from the recital of which Attic drama was developed, and gained a footing in the infernal regions, whither we accompany him in the Frogs of Aristophanes. Another country god was Herms, who seems to have been associated with planting and possession as well as with the demarcation and exchange of property, and who was also a conductor of souls to Hades. Finally, there were the Erinyes, children of night and dwellers in subterranean darkness; they could breed pestilence and discord, but could also avert them; they could blast the produce of the soil or increase its luxuriance and fertility; when blood was spilt on the ground, they made it blossom up again in a harvest of retributive hatred; they pursued the guilty during life, and did not relax their grasp after death; all law, whether physical or moral, was under their protection; the same Erinyes who, in the Odyssey, avenge on Oedipus the suicide of his mother, in the Iliad will not allow the miraculous speaking of a horse to continue; and we have seen in the last chapter how, according to Heracleitus, it is they who also prevent the sun from transgressing his appointed limits.54 Dmtr and Persephon, too, seem to have been law-giving goddesses, as their great festival, celebrated by women alone, was called the Thesmophoria, while eternal happiness was promised to those who had been initiated into their mysteries at Eleusis; and we also find that moral maxims were graven on the marble busts of Herms placed along every thoroughfare in Athens. We can thus understand why the mutilation of these Hermae caused such68 rage and terror, accompanied, as it was rumoured to be, by a profanation of the Eleusinian mysteries; for any attack on the deities in question would seem to prefigure an attack on the settled order of things, the popular rights which they both symbolised and protected."My darling," he whispered, "what does it all mean?"
TWO:"1. The young men need not fear that they will be taken to Germany in order to serve in the German army, or be compelled to do any work."You have been so long," she said, pitifully, "so very long. And why didn't you come when I heard you standing by the door."
TWO:"All right," Hetty said cheerfully. "I'll go and get it for you.""I--I thought you were in prison," she gasped.

TWO:Side by side, however, with these exalted aspirations, the old popular belief in a subterranean abode of souls survived under its very crudest forms; and here also modern explorations have brought to light very surprising evidence of the strength with which the grotesque idea of Charon the Stygian ferryman still kept its hold on the imagination of uneducated people. Originally peculiar to Greece, where it still exists under a slightly altered form, this superstition penetrated into the West at a comparatively early period. Thus in the tombs of Campania alone many hundred skeletons have been found with bronze coins in their mouths, placed there to pay their passage across the Styx; and explorations at Praeneste show that this custom reaches back to the middle of the237 fourth century B.C. We also learn from Lucian that, in his time, the old animistic beliefs were entertained to the extent of burning or burying the clothes, ornaments, and other appurtenances of deceased persons along with their bodies, under the idea that the owners required them for use in the other world; and it is to such deposits that our museums of classical antiquity owe the greater part of their contents.369

TWO:After its temporary adoption by the Academy, Pythagoreanism had ceased to exist as an independent system, but continued to lead a sort of underground life in connexion with the Orphic and Dionysiac mysteries. When or where it reappeared under a philosophical form cannot be certainly determined. Zeller fixes on the beginning of the first century B.C. as the most probable date, and on Alexandria as the most probable scene of its renewed speculative activity.385 Some fifty years later, we find Pythagorean teachers in Rome, and traces of their influence are plainly discernible in the Augustan literature. Under its earliest form, the new system was an attempt to combine mathematical mysticism with principles borrowed from the Stoic and other philosophies; or perhaps it was simply a return to the poetical syncretism of Empedocles. Although composed of fire and air, the soul is declared to be immortal; and lessons of holiness are accompanied by an elaborate code of rules for ceremonial purification. The elder Sextius, from whom Seneca derived much of his ethical enthusiasm, probably belonged to this school. He taught a morality apparently identical with that of Stoicism in every point except the inculcation of abstinence from animal food.386 To this might be added the practice of nightly self-confessionan examination from the moral point of view of how ones whole day has been spent,were we certain that the Stoics did not originate it for themselves.387"I always heard that there was only a foot or two of water in there," the Countess said. "It was never used in my time--people don't care to drink well water in London. Still, it is a slice of luck, as you say."

"Here they are, with your signature on the back of every one of them," he said. "There is nothing singular about that, seeing that so many tradesmen insist upon having banknotes endorsed. Question is, What's the explanation?"He got away at length to his own room. The servants greeted him with smiling faces, the housekeeper was in tears.Text-books, such as relate to construction, consist generally of examples, drawings, and explanations of machines, gearing, tools, and so on; such examples are of use to a learner, no doubt, but in most cases he can examine the machines themselves, and on entering a shop is brought at once in contact not only with the machines but also with their operation. Examples and drawings relate to how machines are constructed, but when a learner comes to the actual operation of machines, a new and more interesting problem is reached in the reasons why they are so constructed.[50]"Oh yes, the Netherlanders are our friends; they remain neutral. And that is the best, for otherwise the whole lot would be smashed up, exactly as here in Belgium."
