Handling and moving material is the principal matter to be considered in the arrangement of engineering works. The constructive manipulation can be watched, estimated, and faults detected by comparison, but handling, like the designs for machinery, is a more obscure matter, and may be greatly at fault without its defects being apparent to any but those who are highly skilled, and have had their attention especially directed [73] to the matter.It is a simple affair, this putting up one's hands, but even at such a moment a free citizen has a strong objection against being compelled to this by others, who are no more than one's self, who ask it without any right, except the might derived from the weapon in their hands.In his attacks on the prevalent theories of ethics, Aenesidmus again reminds us both of Protagoras and of modern agnosticism. According to him, the general disagreement of mankind proves, among other things, that there is no definable highest goodit is neither virtue, nor pleasure, nor knowledge.298 In the absence of any dogmatic teaching on the subject at the time when he lived, Protagoras could not give an opinion with regard to the summum bonum; but Platos famous dialogue represents him as one who, from his point of view, would be unwilling to admit the possibility of introducing fixed principles into conduct; and in like manner, Mr. Herbert Spencer, while accepting the hedonistic principle, gives it such an extremely general signification that he is thrown back on the sceptical principle of leaving everyone free to follow his own inclinations, provided that, in so doing, he does not interfere with the liberty of others.

    THREE:The term gearing, which was once applied to wheels, shafts, and the general mechanism of mills and factories, has now in common use become restricted to tooth wheels, and is in this sense employed here. Gearing as a means of transmitting motion is employed when the movement of machines, or the parts of machines, must remain relatively the same, as in the case of the traversing screw of an engine lathewhen a heavy force is transmitted between shafts that are near to each other, or when shafts to be connected are arranged at angles with each other. This rule is of course not constant, except as to cases where positive relative motion has to be maintained. Noise, and the liability to sudden obstruction, may be reasons for not employing tooth wheels in many cases when the distance between and the position of shafts would render such a connection the most durable and cheap. Gearing under ordinary strain, within limited speed, and when other conditions admit of its use, is the cheapest and most durable mechanism for transmitting power; but the amount of gearing employed in machinery, especially in Europe, is no doubt far greater than it will be in future, when belts are better understood.

    THREE:"Rather. An expert couldn't do it under an hour. Both those tyres will have to come off. Now what are we to do?"Bruce smiled grimly. He knew perfectly well what a terrible significance lay behind these formal words. At the same time, he had no desire to take any advantage. There was an electric thrill in the audience as he was sworn. They thrilled with a deeper intensity as he proceeded. If ever a man stood up and committed moral and social suicide Dr. Gordon Bruce was that man at this moment.

Descartes theory of the universe included, however, something more than extension (or matter) and motion. This was Thought. If we ask whence came the notion of Thought, our philosopher will answer that it was obtained by looking into himself. It was, in reality, obtained by looking into Aristotle, or into some text-book reproducing his metaphysics. But the Platonic element in his system enabled Descartes to isolate Thought much more completely than it had been isolated by Aristotle. To understand this, we must turn once more to the Timaeus. Plato made up his universe from space and Ideas. But the Ideas were too vague or too unintelligible for scientific purposes. Even mediaeval Realists were content to replace them by Aristotles much clearer doctrine of Forms. On the other hand, Aristotles First Matter was anything but a satisfactory conception. It was a mere abstraction; the390 unknowable residuum left behind when bodies were stripped, in imagination, of all their sensible and cogitable qualities. In other words, there was no Matter actually existing without Form; whereas Form was never so truly itself, never so absolutely existent, as when completely separated from Matter: it then became simple self-consciousness, as in God, or in the reasonable part of the human soul. The revolution wrought by substituting space for Aristotles First Matter will now become apparent. Corporeal substance could at once be conceived as existing without the co-operation of Form; and at the same stroke, Form, liberated from its material bonds, sprang back into the subjective sphere, to live henceforward only as pure self-conscious thought.(1.) Why does machinery involve so many cylindrical forms?(2.) Why is it desirable to have separate feed gear for turning and screw cutting?(3.) What is gained by the frictional starting gearing now applied to the finer class of lathes?(4.) How may the alignment of a lathe be tested?(5.) What kind of deviation with a lathe carriage will most affect the truth of work performed?(6.) How may an oval hole be bored on a common slide lathe?(7.) How can the angular [128] ways of a lathe and the corresponding grooves in a carriage be planed to fit without employing gauges?(8.) Give the number of teeth in two wheels to cut a screw of ten threads, when a leading screw is four threads per inch?4. Proportions of the various parts, including the framing, bearing surfaces, shafts, belts, gearing, and other details.
