THREE:The most perfect castings for gear wheels and pulleys and other pieces which can be so moulded, are made by drawing the patterns through templates without rapping. These templates are simply plates of metal perforated so that the pattern can be forced through them by screws or levers, leaving the sand intact. Such templates are expensive to begin with, because of the accurate fitting that is required, especially around the teeth of wheels, and the mechanism that is required in drawing the patterns, but when a large number of pieces are to be made from one pattern, such as gear wheels and pulleys, the saving of labour will soon pay for the templates and machinery required, to say nothing of the saving of metal, which often amounts to ten per cent., and the increased value of the castings because of their accuracy.

THREE:Hetty was waiting for him now in Lawrence's study. She looked bright and cheerful so that Bruce kissed her passionately. It would be hard if he could not live up to her courage and devotion.But we cant set down or do anythingand we cant see much for the fog, objected Dick. I think we ought to go back and drop a note onto the yacht, telling the people to come here in a boat.

    TWO:"On August 15th a fierce fight took place between the French troops on the left bank of the Meuse and the Germans who approached from the east. The Germans were defeated, put to flight, and chased by the French, who crossed the river. On that day the town was not damaged much. Some houses were destroyed by German howitzers, which were undoubtedly aimed at the French regiments on the left bank. One Red Cross helper who lived at Dinant was killed by a German bullet when he was taking up one of the wounded.

The force of gravity acts only in one directionvertically, so that the main force of hoisting and handling machinery which opposes gravity must also act vertically, while the horizontal movement of objects may be accomplished by simply overcoming the friction between them and the surfaces on which they move. This is seen in practice. A force of a hundred pounds may move a loaded truck, which it would require tons to lift; hence the horizontal movements of material may be easily accomplished by hand with the aid of trucks and rollers, so long as it is moved on level planes; but if a weight has to be raised even a single inch by reason of irregularity in floors, the difference between overcoming frictional contact and opposing gravity is at once apparent.Probably more than one hundred civilians had been shot, whereas many perished in the cellars. The heads of the municipality and several priests had at first been taken as hostages. Bail of ten million francs was asked for their release, but after much haggling they consented to accept one and a half millions, which sum was forthcoming from the various local banks.To get rid of superstitious beliefs was, no doubt, a highly meritorious achievement, but it had been far more effectually57 performed by the great pre-Socratic thinkers, Heracleitus, Empedocles, Anaxagoras, and Democritus. These men or their followers had, besides, got hold of a most important principlethe vital principle of all sciencewhich was the reign of law, the universality and indefeasibility of physical causation. Now, Epicurus expressly refused to accept such a doctrine, declaring that it was even worse than believing in the gods, since they could be propitiated, whereas fate could not.119 Again, Greek physical philosophy, under the guidance of Plato, had been tending more and more to seek for its foundation in mathematics. Mathematical reasoning was seen to be the type of all demonstration; and the best hopes of progress were staked on the extension of mathematical methods to every field of enquiry in turn. How much might be done by following up this clue was quickly seen not only in the triumphs of geometry, but in the brilliant astronomical discoveries by which the shape of the earth, the phases of the moon, and the cause of eclipses were finally cleared up and placed altogether outside the sphere of conjecture. Nor was a knowledge of these truths confined to specialists: they were familiar alike to the older Academy, to the Peripatetic, and to the Stoic schools; so that, with the exception of those who doubted every proposition, we may assume them to have been then, as now, the common property of all educated men. Epicurus, on the other hand, seems to have known nothing of mathematics, or only enough to dispute their validity, for we are told that his disciple Polyaenus, who had previously been eminent in that department, was persuaded, on joining the school, to reject the whole of geometry as untrue;120 while, in astronomy, he pronounced the heavenly bodies to be no larger than they appear to our senses, denied the existence of Antipodes, and put the crudest guesses of early philosophy on the same footing with the best-authenticated results of later observation. It is no wonder, then, that during the whole58 continuance of his school no man of science ever accepted its teaching, with the single exception of Asclepiades, who was perhaps a Democritean rather than a disciple of the Garden, and who, at any rate, as a physiologist, would not be brought into contact with its more flagrant absurdities.In the driving gearing of planing machines, conditions which favour the reversing movement are high speed and narrow driving belts. The time in which belts may be shifted is as their speed and width; to be shifted a belt must be deflected or bent edgewise, and from this cause wind spirally in order to pass from one pulley to another. To bend or deflect a belt edgewise there will be required a force in proportion to its width, and [133] the time of passing from one pulley to another is as the number of revolutions made by the pulleys.This absolute separation of Form and Matter, under their new names of Thought and Extension, once grasped, various principles of Cartesianism will follow from it by logical necessity. First comes the exclusion of final causes from philosophy, or rather from Nature. There was not, as with Epicurus, any anti-theological feeling concerned in their rejection. With Aristotle, against whom Descartes is always protesting, the final cause was not a mark of designing intelligence imposed on Matter from without; it was only a particular aspect of Form, the realisation of what Matter was always striving after by virtue of its inherent potentiality. When Form was conceived only as pure thought, there could be no question of such a process; the most highly organised bodies being only modes of figured extension. The revival of Atomism had, no doubt, a great deal to do with the preference for a mechanical interpretation of life. Aristotle had himself shown with masterly clearness the difference between his view of Nature and that taken by Democritus; thus indicating beforehand the direction in which an alternative to his own teaching might be sought; and Bacon had, in fact, already referred with approval to the example set by Democritus in dealing with teleological enquiries.
