In compression processes no material is cut away as in cutting or grinding, the mass being forced into shape by dies or forms that give the required configuration. The action of compressing machines may be either intermittent, as in the case of rolling mills; percussive, as in steam hammers, where a great force acts throughout a limited distance; or gradual and sustained, as in press forging. Machines of application, for abrading or grinding, are constantly coming more into use; their main purpose being to cut or shape material too hard to be acted upon by compression or by cutting processes. It follows that the necessity for machines of this kind is in proportion to the amount of hard material which enters into manufactures; in metal work the employment of hardened steel and iron is rapidly increasing, and as a result, grinding machines have now a place among the standard machine tools of a fitting shop.

FORE:With Neros visit to Greece in 66 the reaction begins. When, a few years later, the empire was disputed between a general from Gaul and a general from Syria, it was the candidate of the Eastern legions who prevailed; the revolt of Judaea drew attention to Eastern affairs; and the great campaigns of Trajan must have definitely turned the tide of public interest in that direction, notwithstanding the far-sighted protest of Tacitus. On more peaceful ground, Hadrians Asiatic tours and his protracted residence in Athens completed the work inaugurated by Nero. In his reign, the intellectual centre of gravity is definitely transferred to Greece; and Roman literature, after its last blaze of splendour under Trajan, becomes extinct, or survives only in forms borrowed from the sophistical rhetoric of the East.A book containing the pattern record should be kept, in which these catalogue numbers are set down, with a short description to identify the different parts to which the numbers belong, so that all the various details of any machine can at any time be referred to. Besides this description, there should be opposite the catalogue of pattern numbers, ruled spaces, in which to enter the weight of castings, the cost of the pattern, and also the amount of turned, planed, or bored surface on each piece when it is finished, or the time required in fitting, which is the same thing. In this book the assembled parts of each machine should be set down in a separate list, so that orders for castings can be made from the list without other references. This system is the best one known to the writer, and is in substance a plan now adopted in many of the best engineering establishments. A complete system in all things pertaining to drawings and classifications should be rigidly adhered to; any plan is better than none, and the schooling of the mind to be had in the observance of systematic rules is a matter not to be neglected. New plans for promoting system may at any time arise, but such plans cannot be at any [87] time understood and adopted except by those who have cultivated a taste for order and regularity.
FORE:Meanwhile the brilliant society season was drawing to a close. Few smart functions remained, but there would be no more dashing affair than the forthcoming ball at Lytton Avenue. The supper was coming from Paris, the decorations were unique, the flowers were to cost upwards of a thousand pounds. The society papers had more or less veracious paragraphs, a score of lady journalists were making copy of the affair.
FORE:"The Duchess wants me to see her boy at once," he said. "The Duchess, you know; the one who so annoyed you at Lady Longmere's party."
FORE:CHAPTER XXVI. THE BLACK MOTOR.
FORE:"You are a clever young man; without doubt you are a very clever young man," he said. "And perhaps I have been mistaken. And I am suspicious; I have good cause to be. One reads in books of honest men who are the souls of integrity. Ah! But then I have never met with such a one in business."

TWO:So far Aristotle gives us a purely superficial and sensational view of the drama. Yet he could not help seeing that there was a moral element in tragedy, and he was anxious to show, as against Plato, that it exercised an improving effect on the audience. The result is his famous theory of the Catharsis, so long misunderstood, and not certainly understood even now. The object of Tragedy, he tells us, is to purify (or purge away) pity and terror by means of those emotions themselves. The Poetics seems originally to have contained an explanation of this mysterious utterance, now lost, and critics have endeavoured to supply the gap by writing eighty treatises on the subject. The result has been at least to show what Aristotle did not mean. The popular version of his dictum, which is that tragedy purges the passions by pity and terror, is clearly inconsistent with the wording of the original text. Pity and terror are both the object and the instrument of purification. Nor yet does he mean, as was once supposed,306 that each of these emotions is to counterbalance and moderate the other; for this would imply that they are opposed to one another, whereas in the Rhetoric he speaks of them as being akin; while a parallel passage in the Politics188 shows him to have believed that the passions are susceptible of homoeopathic treatment. Violent enthusiasm, he tells us, is to be soothed and carried off by a strain of exciting, impassioned music. But whence come the pity and terror which are to be dealt with by tragic poetry? Not, apparently, from the piece itself, for to inoculate the patient with a new disease, merely for the sake of curing it, could do him no imaginable good. To judge from the passage in the Politics already referred to, he believes that pity and terror are always present in the minds of all, to a certain extent; and the theory apparently is, that tragedy brings them to the surface, and enables them to be thrown off with an accompaniment of pleasurable feeling. Now, of course, we have a constant capacity for experiencing every passion to which human nature is liable; but to say that in the absence of its appropriate external stimulus we are ever perceptibly and painfully affected by any passion, is to assert what is not true of any sane mind. And, even were it so, were we constantly haunted by vague presentiments of evil to ourselves or others, it is anything but clear that fictitious representations of calamity would be the appropriate means for enabling us to get rid of them. Zeller explains that it is the insight into universal laws controlling our destiny, the association of misfortune with a divine justice, which, according to Aristotle, produces the purifying effect;189 but this would be the purgation of pity and terror, not by themselves, but by the intellectual framework in which they are set, the concatenation of events, the workings of character, or the reference of everything to an eternal cause. The truth is that Aristotles explanation of the moral effect produced by tragedy is307 irrational, because his whole conception of tragedy is mistaken. The emotions excited by its highest forms are not terror and pity, but admiration and love, which, in their ideal exercise, are too holy for purification, too high for restriction, and too delightful for relief.A hoarse voice wanted to know what was wrong. But it mattered little what noise the speaker made at the other end of the wire so long as the caller spoke under her breath. She proceeded to explain.

TWO:"That is to say ... yes. I have suggested these measures and they have been consented to. I hope that they may induce all the refugees in The Netherlands to return at once. A press bureau in your country has circulated the report that I too had planned to fly. There was no truth in it at all. It was my duty not to leave my people, is not that so? The shepherd must stay with his sheep, the vicars must do the same, and those who went away must therefore come back."CHAPTER XXXIII. SHAPING MACHINES.
TWO:The De Rerum Natura is the greatest of Roman poems, because it is just the one work where the abstract genius of Rome met with a subject combining an abstract form with the interest and inspiration of concrete reality; where negation works with a greater power than assertion; where the satire is directed against follies more wide-spread and enduring than any others; where the teaching in some most essential points can never be superseded; and where dependence on a Greek model left the poet free to contribute from his own imagination those elements to which the poetic value of his work is entirely due. By a curious coincidence, the great poet of mediaeval Italy attained success by the employment of a somewhat similar method. Dante represented, it is true, in their victorious combination, three influences against which Lucretius waged an unrelenting warfarereligion, the idealising love of woman, and the spiritualistic philosophy of Greece. Nevertheless, they resemble each other in this important particular, that both have taken an114 abstract theory of the world as the mould into which the burning metal of their imaginative conceptions is poured. Dante, however, had a power of individual presentation which Lucretius either lacked or had no opportunity of exercising; and therefore he approaches nearer to that supreme creativeness which only two races, the Greek and the English, have hitherto displayed on a very extended scale.85

TWO:In the end these stories of the soldiers convinced even the inhabitants that there had been francs-tireurs, but never in the place where they lived, always somewhere else. They could not believe that the Germans could be so cruel and wreck so much property if nothing at all had happened; and when at length the time came that they themselves were obliged to fly, many of them believed that their compatriots who elsewhere acted as francs-tireurs were to blame for all the dire calamities. But if they had had my opportunity to go "elsewhere" and gather information there, they would have been convinced of the untruth, and probably would have heard the name of their own village as90 the scene of the occurrence. That was how rumours and reports got about.

"Sterzel,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.1. The value of pneumatic apparatus in reaching places where steam furnaces cannot be employed."What do you think of the letter, sir?" Prout asked.
