TWO:Considered mechanically as a means of handling material, the human hands are capable of exerting force in any direction, vertically, horizontally, or at any angle, moving at various rates of speed, as the conditions may require, and with varying force within the limits of human strength. These functions enable us to pick up or lay down a weight slowly and carefully, to transport it at a rapid rate to save time, to move it in any direction, and without the least waste of power, except in the case of carrying small loads, when the whole body has to be moved, as in ascending or descending stairs. The power travelling cranes, that are usually employed in machine-fitting establishments, are perhaps the nearest approach that has been made to the human frame in the way of handling mechanism; they, however, lack that very important feature of a movement, the speed of which is graduated at will. It is evident that in machinery of any kind for handling and lifting that moves at a uniform rate of speed, and this rate of speed adapted, as it must be, to the conditions of starting or depositing a load, much time must be lost in the transit, especially when the load is moved for a considerable distance. This uniform speed is perhaps the greatest defect in the lifting machinery in common use, at least in such as is driven by power.In conclusion, I will say on the subject of patterns and castings, that a learner must depend mainly upon what he can see and what is explained to him in the pattern-shop and foundry. He need never fear an uncivil answer to a proper question, applied at the right time and place. Mechanics who have enough knowledge to give useful information of their business, have invariably the courtesy and good sense to impart such information to those who require it.

TWO:The car flashed round the corner of Lytton Avenue on two wheels. There was a jolt and a crash as the flying machine went over a balk of wood laid across the road, and the next instant the occupants were rolling across the path. Just for the moment there was nobody in sight.
FORE:CHAPTER VII. THE SYSTEMATIC PHILOSOPHY OF ARISTOTLE.Mr Ransome of Ipswich, England, where this system of template moulding originated, has invented a process of fitting templates for gear wheels and other kinds of casting by pouring melted white metal around to mould the fit instead of cutting it through the templates; this effects a great saving in expense, and answers in many cases quite as well as the old plan.

FORE:The advantages gained by milling, as stated, are speed, duplication, and accuracy; the disadvantages are the expense of preparing tools and their perishability.No more wounded were taken to the hospitals of Louvain, as it had been decided to send them straight on to Germany for the present; yet there were many wounded men who were being nursed there already, and the doctors had their hands full attending to the wounded who passed the town. Dr. Noyons told me that the previous Sunday a train with 600 wounded had arrived from Northern France, and he and his assistants had been requested "just" to dress the wounds again of some of them. The condition of these unfortunate men must have been awful; not one had a dressing less than eight days old. Most of them had had it on much longer,209 and then these were merely emergency dressings. They were laid on straw in cattle trucks, many of them even in filth, and infection had worsened their condition to a great extent. Dr. Noyons and his colleagues tried to give the poor fellows as much relief as possible, but as a matter of course they could not do very much during a short stay at a station.

FORE:As we went on towards Eerneghem French aviators were heroically reconnoitring above the German lines. One came from Dixmuiden and one from Nieuwpoort; both went to about half-way between these two towns, where the centre of the battle was. The Germans kept up an unbroken artillery fire at those birds in the air. I saw quite near to them shells exploding right and left and discharging dense, black clouds of smoke that disappeared slowly. There were moments when these black stretches of cloud seemed to form a frame round the aeroplanes, but the brave aviators knew how to escape from their assailants by all sorts of tricks. They came down to go up again unexpectedly, entirely changed their direction a moment later, and at last both disappeared undamaged.

FORE:It is worthy of remark that in the Platonic Er?s we have the germor something more than the germof Aristotles whole metaphysical system.135 According to the usual law of speculative evolution, what was subjective in the one becomes objective in the other. With Plato the passion for knowledge had been merely the guiding principle of a few chosen spirits. With Aristotle it is the living soul of Nature, the secret spring of movement, from the revolution of the outermost starry sphere to the decomposition and recomposition of our mutable terrestrial elements; and from these again through the whole scale of organic life, up to the moral culture of man and the search for an ideally-constituted state. What enables all these myriad movements to continue through eternity, returning ever in an unbroken circle on themselves, is the yearning of unformed matterthat is to say, of unrealised powertowards the absolute unchanging actuality, the self-thinking thought, unmoved, but moving every other form of existence by the desire to participate in its ineffable perfection. Born of the Hellenic enthusiasm for beauty, this wonderful conception subsequently became incorporated with the official teaching of Catholic theology. What had once been a theme219 for ribald merriment or for rhetorical ostentation among the golden youth of Athens, furnished the motive for his most transcendent meditations to the Angel of the Schools; but the fire which lurked under the dusty abstractions of Aquinas needed the touch of a poet and a lover before it could be rekindled into flame. The eyes of Beatrice completed what the dialectic of Plato had begun; and the hundred cantos of her adorer found their fitting close in the love that moves the sun and the other stars."Because I am amused, because I am greatly amused. You are wasting your time and all your pretty schemes there. The name of a firm means nothing in business nowadays. I have a different name in every capital in Europe. Also I have another different name in New York. For instance, my firm is called Ernstein and Co., of 149, Broadway. Ah, ah!"

FORE:I think proper to point out these peculiarities, not so much from any importance they may have in themselves, but to suggest critical investigation, and to dissipate any preconceived opinions of forging being a simple matter, easy to learn, and involving only commonplace operations.Drilling differs in principle from almost every other operation in metal cutting. The tools, instead of being held and directed by guides or spindles, are supported mainly by the bearing of the cutting edges against the material.

FORE:Outgeneraled, the hydroplane cut speed and swung toward the yacht, followed by the tender.Nor was this all. As the world of sense was coming back into favour, the world of reason was falling into disrepute. Just as the old physical philosophy had been decomposed by the Sophisticism of Protagoras and Gorgias, so also the dialectic of Socrates was corrupted into the sophistry of Eubulides and Euthydmus. Plato himself discovered that by reasoning deductively from purely abstract premises, contradictory conclusions could be established with apparently323 equal force. It was difficult to see how a decision could be arrived at except by appealing to the testimony of sense. And a moral reform could hardly be effected except by similarly taking into account the existing beliefs and customs of mankind.
