In view of these propositions, I need hardly say to what object machine improvements should be directed, nor which of the considerations named are most affected by a combination of machine functions; the fact is, that if estimates could be prepared, showing the actual effect of machine combinations, it would astonish [70] those who have not investigated the matter, and in many cases show a loss of the whole cost of such machines each year. The effect of combination machines is, however, by no means uniform; the remarks made apply to standard machines employed in the regular work of an engineering or other establishment. In exceptional cases it may be expedient to use combined machines. In the tool-room of machine-shops, for instance, where one man can usually perform the main part of the work, and where there is but little space for machines, the conditions are especially favourable to combination machines, such as may be used in milling, turning, drilling, and so on; but wherever there is a necessity or an opportunity to carry on two or more of these operations at the same time, the cost of separate machines is but a small consideration when compared with the saving of labour that may be effected by independent tools to perform each operation. The tendency of manufacturing processes of every kind, at this time, is to a division of labour, and to a separation of each operation into as many branches as possible, so that study spent in "segregating" instead of "aggregating" machine functions is most likely to produce profitable results.(1.) Can the driving power be employed directly to shift the belts of a planing machine?(2.) Why are planing machines generally constructed with a running carriage instead of running tools?(3.) What objection exists in employing a train of spur wheels to drive a planing machine carriage?(4.) What is gained by shifting the belts of a planing machine differentially?(5.) What produces the screeching of belts so common with planing machines?(6.) What conditions favour the shifting of planing machine belts?

  • ONE:As we crossed the bridge, I asked my escort why these houses were set on fire. I heard then, for the first time, that "they had been shooting," and they told me of cowardly civilians, who shot from the windows at unsuspicious soldiers, or24 stabbed them treacherously. But of course they had experienced nothing of the kind; it had happened to troops who were now moving ahead. They had, however, taken part in the revenge, and told of it with glittering eyes: how they fired the houses of francs-tireurs and then shot the people who, nearly stifled, appeared at the windows; how in "holy" anger, in order to avenge their comrades, they subsequently entered the houses and destroyed everything. I did not answer, did not know what to think of it, but shuddered, because it was so gruesome. TWO:

It took all my courage and all my nerve to appear at that moment, because they might have done me a mischief also." TWO:Maitrank chuckled as he passed down the steps. A policeman bade him goodnight, a policeman chatting to a man in evening dress. The policeman passed along the empty road, the other followed Maitrank. A second later and Maitrank staggered, and fell headlong in the roadway.
  • ONE:The problem, then, which Spinoza set himself was, first, to account for the fundamental assumptions of all science, and more particularly of geometry, by deducing them from a single self-evident principle; and then to use that principle for the solution of whatever problems seemed to stand most in need of its application. And, as usually happens in such adventurous enterprises, the supposed answer of pure reason was obtained by combining or expanding conceptions borrowed without criticism from pre-existing systems of philosophy.We have illustrated the position of Cicero by reference to the master who, more than any other Greek philosopher, seems to have satisfied his ideal of perfect wisdom. We must now observe that nothing is better calculated to show how inadequate was the view once universally taken of Socrates, and still, perhaps, taken by all who are not scholars, than that it should be applicable in so many points to Cicero as well. For, while the influence of the one on human thought was the greatest ever exercised by a single individual, the influence of the other was limited to the acceleration of a movement already in full activity, and moreover tending on the whole in a retrograde direction. The immeasurable superiority of the Athenian lies in his dialectical method. It was not by a mere elimination of differences that he hoped to establish a general agreement, but by reasoning down from admitted principles, which were themselves to be the result of scientific induction brought to bear on a comprehensive and ever-widening area of experience. Hence his scepticism, which was directed against authority, tended as much to stimulate enquiry as that of the Roman declaimer, which was directed against reason, tended to deaden or to depress it. Hence, also, the political philosophy of Socrates was as revolutionary as that of his imitator was conservative. Both were, in a certain sense, aristocrats; but while the aristocracy176 of the elegant rhetorician meant a clique of indolent and incapable nobles, that of the sturdy craftsman meant a band of highly-trained specialists maintained in power by the choice, the confidence, and the willing obedience of an intelligent people. And while the religion of Cicero was a blind reliance on providence supplemented by priestcraft in this world, with the hope, if things came to the worst, of a safe retreat from trouble in the next; the religion of Socrates was an active co-operation with the universal mind, an attempt to make reason and the will of God prevail on earth, with the hope, if there was any future state, of carrying on in it the intellectual warfare which alone had made life worth living here. No less a contrast could be expected between the orator who turned to philosophy only for the occupation of a leisure hour, or for relief from the pangs of disappointed ambition, and the thinker who gave her his whole existence as the elect apostle and martyr of her creed.

  • THREE:Referring first to the saving effected by combining several operations in one machine, there is perhaps not one constructor in twenty that ever stops to consider what is really gained, and perhaps not one purchaser in a hundred that does the same thing. The impression is, that when one machine performs two operations it saves a second machine. A remarkable example of this exists in the manufacture of combination machines in Europe for working wood, where it is common to find complicated [69] machines that will perform all the operations of a joiner's shop, but as a rule only one thing at a time, and usually in an inconvenient manner, each operation being hampered and interfered with by another; and in changing from one kind of work to another the adjustments and changes generally equal and sometimes exceed the work to be done. What is stranger still is, that such machines are purchased, when their cost often equals that of separate machines to perform the same work.

FORE:"'And then there is something else. The brakesman of the wagon in which I travelled was a man who had enlisted only a couple of weeks ago as a volunteer for the service on the railways, and, if I remember correctly, hailed from Hamburg. He belonged to a Trades union which had already once made a trip to Amsterdam and Rotterdam, and was for instance able to tell me that Krasnapolsky at Amsterdam was a large hotel. I also spoke to that man about what had happened, because I thought I had noticed that he was more human, but he too gave me the cynical answer: "Oh well, the French may have something to eat, they fight also for their country, but not those British, they only fight because that is their profession."The theorems, formul?, constants, tables, and rules, which are generally termed the principles of mechanics, are in a sense only symbols of principles; and it is possible, as many facts will prove, for a learner to master the theories and symbols of mechanical principles, and yet not be able to turn such knowledge [2] to practical account.

FORE:In business arrangements, technical knowledge and professional experience become capital, and offset money or property, not under any general rule, nor even as a consideration of which the law can define the value or prescribe conditions for. The estimate placed upon technical knowledge when rated as capital in the organisation of business firms, and wherever it becomes [21] necessary to give such knowledge a commercial value, furnishes the best and almost the only source from which an apprentice can form an opinion of the money value of what he is to acquire during his apprenticeship.

    FORE:Plotinus, as we have said, starts with the Aristotelian account of Matter; but by a process of dialectical manipulation, he gradually brings it into almost complete agreement with Platos conception; thus, as usual, mediating between and combining the views of his two great authorities. In the first place, he takes advantage of Aristotles distinction between intelligible and sensible Matter, to strip the latter of that positive and vital significance with which it had been clothed in the Peripatetic system. In the world of Ideas, there is an element common to all specific forms, a fundamental unity in which they meet and inhere, which may without impropriety be called their Matter. But this Matter is an eternal and divine substance, inseparably united with the fixed forms which it supports, and, therefore, something which, equally with them, receives light and life and thought from the central source of being. It is otherwise with sensible Matter, the common substance of the corporeal elements. This is, to use the energetic expression of our philosopher, a decorated corpse.481 It does not remain constantly combined with any form, but is for ever passing from one to another, without manifesting a particular preference for any. As such, it is the absolute negation of Form, and can only be conceived, if at all, by326 thinking away every sensible quality. Neither has it any quantity, for quantity means magnitude, and magnitude implies definite figure. Aristotle opposed to each particular form a corresponding privation, and placed Matter midway between them. Plotinus, on the other hand, identifies Matter with the general privation of all forms. It is at this point that he begins to work his way back to the Platonic notion of Matter as simple extension. There must, after all, be something about Matter which enables it to receive every kind of quality and figure,it must have some sort of mass or bulk, not, indeed, in any definite sense, but with an equal capacity for expansion and for contraction. Now, says Plotinus, the very indeterminateness of Matter is precisely the capacity for extension in all directions that we require. Having no principle of stability, but being borne towards every form, and easily led about in all directions, it acquires the nature of a mass.482
THREE:So also with Aristotle. As a naturalist, he is, indeed, purely objective; but when he offers a general explanation of the world, the subjective element introduced by Protagoras and Socrates at once reappears. Simple absolute self-consciousness is for him the highest good, the animating principle of Nature, the most complete reality, and the only one that would remain, were the element of nonentity to disappear from this world. The utter misconception of dynamic phenomena which marks his physics and astronomy can only be accounted for by his desire to give life the priority over mechanical motion, and reason the priority over life. Thus his metaphysical method is essentially identical with the introspective method recommended by Plotinus, and, if fully worked out, might have led to the same results.The result of recent enquiries into the state of civilisation under the Roman Empire during the first two centuries of its existence, has been to suggest conclusions in many respects at variance with those formerly entertained. Instead of the intellectual stagnation, the moral turpitude, and the religious indifference which were once supposed to have been the most marked characteristics of that period, modern scholars discern symptoms of active and fruitful thought, of purity and disinterestedness both in public and private life, but above all of a religious feeling which erred far more on the side of excess than on the side of defect. This change of view may be traced to various causes. A new class of investigators have made ancient history an object of special study. Fresh evidence has been brought to light, and a more discriminating as well as a more extended use has been made of the sources already available. And, perhaps, even greater importance is attributable to the principle now so generally accepted, that historical phenomena, like all other phenomena, are essentially continuous in their movement. The old theories assumed that the substitution of Christian for what is called Pagan196 civilisation was accompanied by a sudden break in mens habits and ideas. But the whole spirit of modern philosophy has prepared us to believe that such a break is not likely to have ever occurred. And a new survey of the period in question is leading us to the conviction that, as a matter of fact, it did not occur. Sign Up

FORE:
Near Corbeek-Loo a strong Belgian force had been able even to reach the main road to Louvain, and there also destroyed the railway, after which they retreated before the advancing Germans."After this infernal rumble, deadly silence followed, interrupted only by the groans of the wounded. The German artillery ceased to fire, and from all sides their infantry came rushing on, their faces expressing the terror caused by such great calamities. They were no longer soldiers longing to destroy, but human beings hurrying to go to the assistance of other human beings."'On October 9th no train with two thousand wounded arrived at the station of Landen, but only small transports whose number can be checked accurately by the lists of wounded. Rioting by two to three hundred soldiers near a carriage could not take place, as the station guard was instructed to keep free a path along the train. There is, moreover, always an officer of the station-guard present, when a train with wounded leaves. It is impossible that the soldiers could have aimed their rifles at the British, as the men who get their food in the dining-hall, as also the serving military personnel, are always unarmed. Other soldiers are not admitted to the station. The British have neither been beaten, nor stabbed, nor spit at; on the contrary plates full of hot soup have been offered them which were refused by two of them. This has been confirmed by the declarations of people who were present.'"
