Attention has been called to this case as one wherein the conditions of operation obviously furnish true data to govern the arrangement of machinery, instead of the determinable strains to which the parts are subjected, and as a good example of the importance of studying mechanical conditions from a practical and experimental point of view. If the general diameter of a shaft is based upon the exact amount of power to be transmitted, or if the diameter of a shaft at various parts is based upon the torsional stress that would be sustained at these points, such a shaft would not only fail to meet the conditions of practical use, but would cost more by attempting such an adaptation. The regular working strain to which shafts are subjected is inversely as the speed at which they run. This becomes a strong reason in favour of arranging shafts to run at a maximum speed, provided there was nothing more than first cost to consider; but there are other and more important conditions to be taken into account, principal among which are the required rate of movement where power is taken off to machines, and the endurance of bearings.

Ren shook his head. He could hear nothing at all. He said so impatiently. It seemed to him that his companion was playing with him.One hour before the arrival at Lige the engine of our train dashed into another, and got so badly damaged that all the water from our engine ran away. This caused a delay of another two hours, so that we did not arrive at Lige before dusk, and could not think of reaching The Netherlands that day.

THREE:On the whole, the interview produced nothing of importance. Nor was Lawrence subsequently able to deduce anything from it.
THREE:"Why, what's this?" he exclaimed. "What does the game mean?"She flashed across the hall without the slightest sound, and had passed into the street before Hetty deemed it prudent to follow. The girl was taking a terrible risk for the sake of her lover, and she knew it. But she must follow.

THREE:There was nobody to turn to, nobody to advise her now, but Balmayne. He had done pretty well on the whole; he had contrived to keep himself out of danger, and at the first sign of the collapse he would fly."I must have changed them," he sobbed. "I changed them and forgot; perhaps I had them in my hands looking at the beauties."

THREE:Improvements, which have totally changed machine fitting during thirty years past, have been of a character to dispense in a great measure with hand skill, and supplant it with what may be termed mental skill. The mere physical effect produced by a man's hands has steadily diminished in value, until it has now almost come to be reckoned in foot-pounds; but the necessity [166] for practical knowledge instead of being diminished is increased.

THREE:Prout was surprised. Not that he ought to have been surprised after the strange things that had come in his way professionally. The way he conveyed the impression that all this was news to him was artistic. He asked a score of questions, he made voluminous notes solemnly in a large book.
FORE:"Why she married Leon I cannot say. Perhaps it was because he bullied her. But Leon was no saint, and he drank, and he got into gaol, and Leona left him. For a long time we did not hear what had become of her. Then I saw her in Paris at a circus. A little time later and she was mixed up in politics in Rome. But she got steadily on, living in a more luxurious way till I lost sight of her altogether.

FORE:Such were the priori elements which a historical synthesis had prepared to satisfy the want of a metaphysical Absolute. Let us now see what result would follow when the newly-recovered idea of space was subjected to a metaphysical analysis. Extension is both one and infinite. No particular area can be conceived apart from the whole which both contains and explains it. Again, extension is absolutely homogeneous; to whatever distance we may travel in imagination there will still be the same repetition of similar parts. But space, with the Cartesians, meant more than a simple juxtaposition of parts; having been made the essence of matter, it was invested with mechanical as well as with geometrical properties. The bodies into which it resolved itself were conceived as moving, and as communicating their movement to one another through an unbroken chain of causation in which each constituted a single link, determining and determined by the rest; so that, here also, each part was explained by reference to an infinite whole, reproducing its essence, while exempt from the condition of circumscribed existence. We can understand, then, that when the necessity of accounting for extension itself once became felt, the natural solution would be to conceive it as holding the same relation to some greater whole which its own subdivisions held to their sum total; in other words it should be at once a part, an emanation, and an image of the ultimate reality. This is, in fact, very nearly the relation which Matter holds to the One in the Neo-Platonic system. And we know that with Plotinus Matter is almost the same as infinite Extension.

THREE:Assuming, for example, that a machine will cost as much as the wages of an attendant for one year, which is not far from an average estimate for iron working machine tools, and that interest, wear, and repairs amount to ten per cent. on this sum, then the attendance would cost ten times as much as the machine; in other words, the wages paid to a workman to attend a machine is, on an average, ten times as much as the other expenses attending its operation, power excepted. This assumed, it follows that in machine tools any improvement directed to labour saving is worth ten times as much as an equal improvement directed to the economy of first cost.III.

FORE:Next to Temperance comes Fortitude; and with it the difficulties of reconciling Epicureanism with the ordinary morality are considerably increased. The old conception of this virtue was willingness to face pain and death on behalf of a noble cause,138 which would be generally understood to mean the salvation of family, friends, and fatherland; and the ultimate sanction of such self-devotion was found in the pressure of public opinion. Idealistic philosophy, taking still higher ground, not69 only refused to balance the fear of pain and death against the fear of infamy or the hope of applause, but added public opinion to the considerations which a good man in the discharge of his duty would, if necessary, despise. Epicurus also inculcated disregard for reputation, except when it might lead to inconveniences of a tangible description;139 but he had nothing beyond the calculations of self-interest to put in its place. A modern utilitarian is bound to undergo loss and suffering in his own person for the prevention of greater loss and suffering elsewhere; an egoistic hedonist cannot consistently be brave, except for the sake of his own future security. The method by which Epicurus reconciled interest with courage was to minimise the importance of whatever injuries could be inflicted by external circumstances; just as in his theory of Temperance he had minimised the importance of bodily pleasures. How he disposed of death will best be seen in connexion with his physical philosophy. Pain he encountered by emphasising, or rather immensely exaggerating, the minds power of annulling external sensation by concentrating its whole attention on remembered or anticipated pleasures, or else on the certainty that present suffering must come to an end, and to a more speedy end in proportion to its greater severity. We are to hold a fire in our hand, partly by thinking of the frosty Caucasus, partly by the comforting reflection that the pain of a burn, being intense, will not be of long duration; while, at worst, like the Stoics, we have the resource of suicide as a last refuge from intolerable suffering.140

26VII.There is much in Mr. Mokveld's narrative to interest the historian. For example, he gives a 6 fuller account than we have yet had of that obscure period when Lige had fallen, but its northern forts were still holding out. But it is less a history of the campaign than a chronicle of those lesser incidents of war which reveal the character of the combatants. No more crushing indictment of German methods has been issued, the more crushing since it is so fair and reasonable. The author has very readily set down on the credit side any act of German humanity or courtesy which he witnessed or heard of. But the credit side is meagre and the black list of crimes portentous. Episodes like the burning of Vis and the treatment of British prisoners in the train at Landen would be hard to match in history for squalid horror."Oh, you are a journalist? And what came you here for?""Well, what is it you want tonight?" she demanded, haughtily."Just a moment," Leona said eagerly. "Suppose I deny that. How are you going to prove that I did so?"
