ENGLISH 京香所有作品封面A little farther on a few houses were left undamaged, because they stood outside the town proper. A woman who had remained in her house stood outside with cigar-boxes under her arm. She offered cigars from an open box to the soldiers of the passing divisions. To me she seemed to be out of her mind, as she stood there trembling, her face distorted from hypernervousness. Her cringing kindness was of no avail, for I noticed a couple of days afterwards that her house too had been totally destroyed."Lige,On the hot afternoon of August 7th, 1914, the much-delayed train rumbled into the station at Maastricht. A dense mass stood in front of the building. Men, women, and children were crowded there and pushed each other weeping, shouting, and questioning. Families and friends tried to find each other, and many of the folk of Maastricht assisted the poor 16creatures, who, nervously excited, wept and wailed for a father, for wife and children lost in the crowd. It was painful, pitiful, this sight of hundreds of fugitives, who, although now safe, constantly feared that death was near, and anxiously clutched small parcels, which for the most part contained worthless trifles hurriedly snatched up when they fled.

At Fort Pontisse or Lierce they seemed to have noticed that the factory was a station for observation. As the officer was still thinking about my case, one of those infernal monster shells crashed down among a group of soldiers, only some yards away. Those who were not hit ran away, but they came back soon, and took up seven or eight comrades, whom they carried into the factory. I shuddered when I saw what had happened, and through the shock the sight gave me I involuntarily jerked my arms.The man got more and more excited, but then he was more than "half-seas over." The smoke made him cough and he stuck in the middle of his "swine." He made me shudder, and I hastened to pull out a packet of cigarettes, some of which I gave to him and his mates. In consequence the two others became more communicative, and in touching harmony assured me that:These remarks upon hammers are not introduced here as a matter of curiosity, nor with any intention of following mechanical principles beyond where they will explain actual manipulation, but as a means of directing attention to percussive acting machines generally, with which forging processes, as before explained, have an intimate connection.

"On August 14th, at about four o'clock in the afternoon, the expected storm burst; for twenty-five hours the invisible siege-guns poured their torrent of projectiles on the fort. Flares of fire and dense clouds of smoke belched through the crevices. As the enemy's batteries could not be located, their fire could not be answered. The artillerists of the garrison were then taken to the spacious chief gallery, which offered a safe refuge under its vault, about two and a half to three yards thick. Outside the sentries were watching. In the parts near the entrance it was unendurable; the heavy projectiles from the guns mounted in the town had nibbled away the outer wall, only a yard and a half thick. There were as yet no casualties among the garrison; calmly they waited for the infernal tempest to subside and the enemy to storm the fort, for they had sworn to repulse the assault.During the week of my compulsory stay in Louvain I had also the privilege of making the acquaintance of two brave compatriots; I mean Professor Noyons and his wife.Tempering may be called a mystery of the smith-shop; this operation has that attraction which characterises every process that is mysterious, especially such as are connected with, or belong to mechanical manipulation. A strange and perhaps fortunate habit of the mind is to be greatly interested in what is not well understood, and to disregard what is capable of plain demonstration.

Trip-hammers employed in forging bear a close analogy to, and were no doubt first suggested by, hand-hammers. Being the oldest of power-forging machines, and extensively employed, it will be proper to notice trip-hammers before steam-hammers.I witnessed Pastor Claes's labours for a moment only, for the smell was unbearable even at a somewhat considerable distance. The good pastor persevered in the work after having started it, with the assistance of some faithful helpers, who all of them had sealed their mouths with a sponge soaked in some disinfectant. The corpses were taken from the cave, money and documents put away in separate bags, and the unfortunate owners coffined and blessed."August 22nd, 1914.

"September 1st, 1914."The arrangement of patterns with reference to having certain parts of castings solid and clean is an important matter, yet one that is comparatively easy to understand. Supposing the iron in a mould to be in a melted state, and to contain, as it always must, loose sand and 'scruff,' and that the weight of the dirt is to melted iron as the weight of cork is to water, it is easy to see where this dirt would lodge, and where it would be found in the castings. The top of a mould or cope, as it is called, contains the dirt, while the bottom or drag side is generally clean and sound: the rule is to arrange patterns so that the surfaces to be finished will come on the bottom or drag side."Now, look here, sister, I am a cousin of S?ur...."

This brings us back to the old proposition, that for structures which do not involve motion, mathematical data will furnish dimensions; but the same rule will not apply in machinery. To follow the proportions for shafts that would be furnished by pure mathematical data would in nearly all cases lead to error. Experience has demonstrated that for ordinary cases, where power is transmitted and applied with tolerable regularity, a shaft three inches in diameter, making one hundred and fifty revolutions a minute, its bearings three to four diameters in length, and placed ten feet apart, will safely transmit fifty horse-power.The material when in its crude state not only consists of various things, such as iron, sand, coal, and lumber, that must be kept separate, but the bulk of such materials is much greater than their finished product. It is therefore quite natural to receive such material on the outside or "periphery" of the works where there is the most room for entrances and for the separate storing of such supplies. Such an arrangement is of course only possible where there can be access to a considerable part of the boundary of a works, yet there are but few cases where a shop cannot be arranged in general upon the plan suggested. By receiving material on the outside, and delivering the finished product from the centre, communications between the departments of an establishment are the shortest that it is possible to have; by observing the plans of the best establishments of modern arrangement, especially those in Europe, it may be seen that this system is approximated in many of them, especially in establishments devoted to the manufacture of some special class of work.In the manufacture of machines, there are usually so many sizes and modifications, that drawings should assist and determine in a large degree the completeness of classification and record. Taking the manufacture of machine tools, for example: we cannot well say, each time they are to be spoken of, a thirty-six inch lathe without screw and gearing, a thirty-two inch lathe with screw and gearing, a forty-inch lathe triple geared or double geared, with a twenty or thirty foot frame, and so on. To avoid this it is necessary to assume symbols for machines of different classes, consisting generally of the letters of the alphabet, qualified by a single number as an exponent to designate capacity or different modifications. Assuming, in the case of engine lathes, A to be the symbol for lathes of all sizes, then those of different capacity and modification can be represented in the drawings and records as A1, A2, A3, A4, and so on, requiring but two characters to indicate a lathe of any kind. These symbols should be marked in large plain letters on the left-hand lower corner of sheets, so that the manager, workman, or any one else, can see at a glance what the [86] drawings relate to. This symbol should run through the time-book, cost account, sales record, and be the technical name for machines to which it applies; in this way machines will always be spoken of in the works by the name of their symbol.

"In Alsace the French are near the Rhine."Her reserve told me that I would not get much information here, and, finishing my beer, I asked:

General engineering work cannot consist in the production of duplicate pieces, nor in operations performed constantly in the same manner as in ordinary manufacturing; hence there has been much effort expended in adapting machines to general purposesmachines, which seldom avoid the objections of combination, pointed out in a previous chapter.General von Buelow says here that he gave his consent to the shooting of about one hundred persons, but I can state with absolute certainty that there were about 400 victims. We must therefore assume that the other 300 were killed without his consent."In the circumstances in which we are placed it is necessary to retain the greatest possible tranquillity and calm.
