      Direct action and reaction are equal; if a force is exerted in any direction there must be an equal force acting in the opposite direction; a machine must absorb its own strains.护こ浃厘播�じ逊ゥSuddenly I saw a boy about twelve years old in one of the burning streets. He waved his arms, rushed madly to and fro, calling for his father and mother, and his little brother and sisters. He was in danger of perishing in the fire, or being killed by the murderous bullet from a rifle. I ran after him, laid hold of him, and in spite of his resistance pulled him back. Fortunately I met a couple of kind, sober soldiers to whom I told the story, and who promised to send the boy away from the burning town.钎い

      Other soldiers kept on running into the burning houses, carrying out vases, pictures, plate, or small pieces of furniture. They smashed everything on81 the cobbles and then returned to wreck more things that would have been destroyed by the fire all the same. It was a revelry of drunken vandalism. They seemed mad, and even risked being burned alive at this work of destruction. Most of the officers were also tipsy; not one of them was saluted by the soldiers.滟Until now we had walked along the right bank of the canal, until we crossed one of the many bridges. The little girl was well-nigh exhausted; from time to time I gave her a rest, and then again I carried her a part of the way.访宽走Many refugees returned to Louvain that morning simply driven by hunger. I myself lived still on the breakfast I had at Maastricht on the previous day, and badly wanted something to eat, but still more a cup of hot coffee, to warm my chilled body. I was able to get the coffee—without milk or sugar—from a peasant along the road, but food was out of the question. Most of the people had nothing left, others saved a piece of bread as hard as a brick for the moment when hunger might drive them to extreme distress. Whatever sums I offered, nothing could be had before I came to Tirlemont, where I was able to buy three eggs.d榱いもさフュ

      "The Reverend Head has been notified already ten times that he would be shot, and he is frequently being arrested for alleged shooting from the building. This shooting is actually done by German soldiers alone, who are loafing and looting, as I myself noticed a short time ago. The Head took me to a room where an old man of ninety, who had just received the extreme unction, lay dying. By his side sat a broken-hearted little old woman, his wife. This old man had been taken prisoner with other men of Visé, and forced to work at a new bridge. The poor fellow broke down under the strain; it cost him his life."りゐ顽盲�き悚ゥ菏いIn making notes, as much as possible of what is written should be condensed into brief formul?, a form of expression which is fast becoming the written language of machine shops. Reading formul? is in a great degree a matter of habit, like studying mechanical drawings; that which at the beginning is a maze of complexity, after a time becomes intelligible and clear at a glance.屿违

      �ヲ阪ゥ膜脯いPatterns and castings are so intimately connected that it would be difficult to treat of them separately without continually confounding them together; it is therefore proposed to speak of pattern-making and moulding under one head.ぅ氦ぬジThe duplicate system has gradually made its way in locomotive engineering, and will no doubt extend to the whole of [150] railway equipment, as constants for dimensions are proved and agreed upon. イМぷグた

      "Ah, so you are a Netherlander, aren't you? Then we are friends. The Netherlands remains neutral, does she not? What news have you from there; are you already at war with Britain?"ヨいハNear Herstal the Germans were crossing by the large bridge, which the Belgians had preserved to their own disadvantage. ゥ雩丧ちIt is stated that some of the wretched people were even pinioned and beaten. Their assailants then stumbled up the stairs and began to shoot wildly from the upper stories into the dark streets, where their own raving comrades were rushing about like madmen. Some civilians who in great fear had come to their front door to see what was happening were shot down.い筏ィ

      �ゥ�翡亡サPattern-makers have to thoroughly understand drawings, in order to reproduce them on the trestle boards with allowance for shrinkage, and to determine the cores; they must also understand moulding, casting, fitting, and finishing. Pattern-making as a branch of machine manufacture, should rank next to designing and drafting.ギい

      "Nothing! But, madame, I want to pay for what I drink!"ぅェいぱ5. Every part laid down has something to govern it that may be termed a "base"—some condition of function or position which, if understood, will suggest size, shape, and relation to other parts. By searching after a base for each and every part and detail, the draughtsman proceeds upon a regular system, continually maintaining a test of what is done. Every wheel, shaft, screw or piece of framing should be made with a clear view of the functions it has to fill, and there are, as before said, always reasons why such parts should be of a certain size, have such a speed of movement, or a certain amount of bearing surface, and so on. These reasons or conditions may be classed as expedient, important, or essential, and must be estimated accordingly. As claimed at the beginning, the designs of machines can only in a limited degree be determined by mathematical data. Leaving out all considerations of machine operation with which books have scarcely attempted to deal, we have only to refer to the element of strains to verify the general truth of the proposition.れIt was a fantastic night. Trains arrived out of the foggy darkness, their screeching whistle resounding from the far distance, and when they steamed into the station a storm of noise arose. All these trains brought British prisoners of war, captured by the Germans at St. Quentin, and hundreds of German soldiers escorted the trains, which were all covered over with green branches, and looked like copse-wood sliding along the railroad. As soon as they rumbled into the station the escorts sang loudly their patriotic songs, and "Germany before all other!" ("Deutschland über Alles!") vibrated through the fog.イ单イけ

      Keeping these various points in mind, an apprentice will derive both pleasure and advantage from tracing their application in steam-hammers, which may come under notice, and various modifications of the mechanism will only render investigation more interesting.抓裥甓意ゼイ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.茎哎い瘠メChasing operations being lathe work, and involving no principles not already noticed, what is said further will be in reference to die-cutting or bolt-threading machines, which, simple as they may appear to the unskilled, involve, nevertheless [144] many intricacies which will not appear upon superficial examination.ゥぉ
