      The traction of belts upon pulleys, like that of locomotive wheels upon railways, being incapable of demonstration except by actual experience, for a long time hindered the introduction of belts as a means of transmitting motion and power except in cases when gearing or shafts could not be employed. Motion is named separately, because with many kinds of machinery that are driven at high speedsuch as wood machinesthe transmission of rapid movement must be considered as well as power, and in ordinary practice it is only by means of belts that such high speeds may be communicated from one shaft to another.Leona Lalage was raging up and down the room as Balmayne entered. The first saffron streaks of dawn were making the electrics thin and yellow. Evidently something had gone wrong. Balmayne waited for his companion to speak.


      Thus Roman civilisation, even when considered on its liberal, progressive, democratic side, seems to have necessarily favoured the growth and spread of superstition, because the new social strata which it turned up were less on their guard against unwarranted beliefs than the old governing aristocracies with their mingled conservatism and culture. But this was not all; and on viewing the empire from another side we shall find that under it all classes alike were exposed to conditions eminently inconsistent with that individual independence and capacity for forming a private judgment which212 had so honourably distinguished at least one class under the republican rgime. If imperialism was in one sense a levelling and democratic system, in another sense it was intensely aristocratic, or rather timocratic. Superiorities of birth, race, age, and sex were everywhere tending to disappear, only that they might be replaced by the more ignoble superiorities of brute-force, of court-favour, and of wealth. The Palace set an example of caprice on the one side and of servility on the other which was faithfully followed through all grades of Roman society, less from a spirit of imitation than because circumstances were at work which made every rich man or woman the centre of a petty court consisting of voluntary dependents whose obsequiousness was rewarded by daily doles of food and money, by the occasional gift of a toga or even of a small farm, or by the hope of a handsome legacy. Before daybreak the doors of a wealthy house were surrounded by a motley crowd, including not only famished clients but praetors, tribunes, opulent freedmen, and even ladies in their litters; all come nominally for the purpose of paying their respects to the master, but in reality to receive a small present of money. At a later hour, when the great man went abroad, he was attended by a troop of poor hangers-on, who, after trudging about for hours in his train and accompanying him home in the afternoon, often missed the place at his table which their assiduities were intended to secure. Even when it came, the invitation brought small comfort, as only the poorest food and the worst wine were set before the client, while he had the additional vexation of seeing his patron feasting on the choicest dishes and the most delicious vintages; and this was also the lot of the domestic philosopher whom some rich men regarded as an indispensable member of their retinue.326 Of course those who wished for a larger share of the patrons favours could only hope to win it by unstinted tokens of admiration, deference, or assent; and213 probably many besides the master of thirty legions in the well-known story were invariably allowed to be right by the scholars with whom they condescended to dispute.Lawrence was deep in the early edition of "The Star." He nodded to Bruce and looked up from his paper eagerly.


      A bell rang somewhere overhead, and Prout was summoned by a tall footman, who sniffed at him suspiciously as he led the way upstairs. In a magnificent wrap Leona Lalage sat. There was a cup of coffee before her. In a flash she saw exactly what had happened. Her hand did not shake now, the cigarette between her lips was steady. She had known that sooner or later this blow must fall.The dear lady rapped it out in such a decided tone of voice that I desisted. I told my trouble to the proprietor of a caf where I took a glass of beer; he, examining my papers, placed confidence in me, and got me a rickety thing, for which I paid twenty-two francs.

      The EndHaving pushed my way through the loafers, who stood waiting before the house, I was able to continue my journey to Maastricht.

      I did not budge.This last sentence brings the matter into a tangible form, and indicates what the subject of gain should have to do with what an apprentice learns of machine construction. Success in an engineering enterprise may be temporarily achieved by illegitimate meanssuch as misrepresentation of the capacity and quality of what is produced, the use of cheap or improper material, or by copying the plans of others to avoid the expense of engineering servicebut in the end the permanent success of an engineering business must rest upon the knowledge and skill that is connected with it.


      The arrangement of patterns with reference to having certain parts of castings solid and clean is an important matter, yet one that is comparatively easy to understand. Supposing the iron in a mould to be in a melted state, and to contain, as it always must, loose sand and 'scruff,' and that the weight of the dirt is to melted iron as the weight of cork is to water, it is easy to see where this dirt would lodge, and where it would be found in the castings. The top of a mould or cope, as it is called, contains the dirt, while the bottom or drag side is generally clean and sound: the rule is to arrange patterns so that the surfaces to be finished will come on the bottom or drag side.

      2. Never seen anyone who was arrested as a franc-tireur.It was stated later on that the German authorities punished the culprits and had them executed at Aix-la-Chapelle; De Tijd of August 31st, 1914, also reported it. But the action of these soldiers was not worse than that of generals who had entire cities destroyed and civilians killed by the hundred, but were always screened by the German Government.

      We have already observed that Scepticism among the ancients was often cultivated in connexion with some positive doctrine which it indirectly served to recommend. In the case of its last supporters, this was the study of medicine on an empirical as opposed to a deductive method. The Sceptical contention is that we cannot go beyond appearances; the empirical contention is, that all knowledge comes to us from experience, and that this only shows us how phenomena are related to one another, not how they are related to their underlying causes, whether efficient or final. These allied points of view have been brought into still more intimate association by modern thought, which, as will be shown in the concluding chapter, has sprung from a modified form of the ancient Scepticism, powerfully aided by a simultaneous development of physical science. At the same time, the new school have succeeded in shaking off the narrowness and timidity of their predecessors, who were still so far under the influence of the old dogmatists as to believe that there was an inherent opposition between observation and reasoning in the methods of discovery, between facts and explanations in the truths of science, and between antecedence and causation in the realities of Nature. In this respect, astronomy has done more for the right adjustment of our conceptions than any190 other branch of knowledge; and it is remarkable that Sextus Empiricus, the last eminent representative of ancient Scepticism, and the only one (unless Cicero is to be called a Sceptic) whose writings are still extant, should expressly except astronomy from the destructive criticism to which he subjects the whole range of studies included in what we should call the university curriculum of his time.301 We need not enter into an analysis of the ponderous compilation referred to; for nearly every point of interest which it comprises has already been touched on in the course of our investigation; and Sextus differs only from his predecessors by adding the arguments of the New Academy to those of Protagoras and Pyrrho, thus completing the Sceptical cycle. It will be enough to notice the singular circumstance that so copious and careful an enumeration of the grounds which it was possible to urge against dogmatismincluding, as we have seen, many still employed for the same or other purposes,should have omitted the two most powerful solvents of any. These were left for the exquisite critical acumen of Hume to discover. They relate to the conception of causation, and to the conception of our own personality as an indivisible, continuously existing substance, being attempts to show that both involve assumptions of an illegitimate character. Sextus comes up to the very verge of Humes objection to the former when he observes that causation implies relation, which can only exist in thought;302 but he does not ask how we come to think such a relation, still less does he connect it with the perception of phenomenal antecedence; and his attacks on the various mental faculties assumed by psychologists pass over the fundamental postulate of personal identity, thus leaving Descartes what seemed a safe foundation whereon to rebuild the edifice of metaphysical philosophy.
