      149 "I prohibit all shooting in the towns without the order of an officer.啶ヂイ禄ヰ(1.) How may the arrangement of an establishment affect its earnings?—(2.) Why is the arrangement of engineering establishments generally irregular?—(3.) Why should an erecting shop be a base of arrangement in engineering establishments?—(4.) What are the principal materials consumed in engineering works?—(5.) Why is not special experience a safe guide in forming plans of shop arrangement?盲ぺバ绁柿Following this proposition into modern engineering examples, we find how practice has gradually conformed to what these properties in belts suggest. Wire and other ropes of small diameter, to avoid air friction, and allowed to droop in low curves to avoid too many supporting pulleys, are now in many cases employed for transmitting power through long distances, as at Schaffhausen, in Germany. This system has been very successfully applied in some cases for distributing power in large manufacturing establishments. Belts, among which are included all flexible bands, do not afford the same facilities for [49]taking off power at different points as shafts, but have advantages in transmitting power to portable machinery, when power is to be taken off at movable points, as in the case of portable travelling cranes, machines, and so on.饯

      The majority of the refugees returning to Louvain belonged to the lower classes, and they began to loot and plunder the town, encouraged thereto by the German soldiers, who threw the things into the streets, and said: "Take it, if you like!" In extenuation of the looting and plundering I might say that the poor wretches tried before all to get hold of half-burned eatables.ず嗓いBetween two of my several trips to Louvain I made one to Namur in the beginning of September, after having secured at Liège, by a trick, a splendid permit which enabled me to travel even by motor-car.ガぴ⒂哎いUnder certain conditions a given quantity of soft iron or steel may be cut away at less expense, and with greater accuracy, by milling than by any other process.ゥ瘳ゥぉ总`

      A carriage moving on angular ways always moves steadily and easily, without play in any direction until lifted from its bearing, which rarely happens, and its lifting is easily opposed by adjustable gibs. A carriage on a flat shear is apt to have play in a horizontal direction because of the freedom which must exist to secure easy movement. In the case of tracks, it may also be mentioned that the weight of a carriage acts as a constant force to hold it steady, while with a flat shear the weight of a carriage is in a sense opposed to the ways, and has no useful effect in steadying or guiding. The rigidity and steadiness of tool movement is notoriously in favour of triangular tracks, so much so that nearly all American machine tool-makers construct lathes in this manner, although it adds no inconsiderable cost in fitting.さ证いIf these various plans of arranging screw-cutting machines had reference to different kinds of work, it might be assumed that all of them are correct, but they are as a rule all applied to the same kind of work; hence it is safe to conclude that there is one arrangement better than the rest, or that one plan is right and the others wrong. This matter may in some degree be determined by following through the conditions of use and application.っはThe gauging system has been no little retarded by a selfish and mistaken opinion that an engineering establishment may maintain peculiar standards of its own; in fact, relics of this spirit are yet to be met with in old machines, where the pitch of screw-threads has been made to fractional parts of an inch, so that engineers, other than the original makers, could not well perform repairing, or replace broken parts.ゴГ澶


      CHAPTER VIII去Strains caused by cutting action, in planing or other machines, fall within and are resisted by the framing; even when the tools are supported by one frame and the material by another, such frames have to be connected by means of foundations which become a constituent part of the framing in such cases.啷ゥ袱イ肖

      "It is a pity, sir, that you did not arrive a day sooner, then you might have witnessed great barbarity of the Germans. If you walk on a little farther along the canal, you will see three persons hanging from a tree near Haccourt; one of these is a boy of fourteen. Nobody was allowed on the road, and as a patrol met these three persons, they concluded immediately that they were francs-tireurs, strung them up on the tree, without a trial of any sort, and in addition shot each a bullet through the head. To-day another patrol arrived and had the effrontery to tell the members of the Maastricht Red Cross that the boy had murdered a captain. And we are not allowed to remove the corpses. Horrible!... horrible!"丹─�ぅイWhen I drove into Namur, I found the town comparatively quiet; there was some traffic in the streets, and Belgian army surgeons and British nurses in their uniforms walked about freely.154 There were many wounded: the German wounded were all placed in the military hospital; the Belgians and the French had been taken to the Sisters of Mercy, the Institution Saint Louis, the High School for Girls, and the Sisters of Our Lady.议ズぅ

      The excellent man went on weeping, and I was not able to console him and did not know what to say. He took my arm, and led me to the large common hall, where twenty wounded Germans lay, who had been hit in the fight for the forts. He went to one bed after the other, and, with tears in his eyes, asked each man how he felt, and inquired, "Are you ... properly ... cared for ... here? Are you?" The sick men turned round, their eyes beamed, and they stammered words full of gratitude. Others said nothing, but took the Head's hand and pressed it long and warmly.铳いち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.ゥふイフIn respect to lathe manipulation, which is perhaps the most difficult to learn of all shop operations, the following hints are given, which may prove of service to a learner: At the beginning the form of tools should be carefully studied; this is one of the great points in lathe work; the greatest distinction between a thorough and indifferent latheman is that one knows the proper form and temper of tools and the other does not. The adjustment and presenting of tools is soon learned by experience, but the proper form of tools is a matter of greater difficulty. One of the first things to study is the shape of cutting edges, both as to clearance below the edge of the tool, and the angle of the edge, with reference to both turning and boring, because the latter is different from turning. The angle of lathe tools is clearly suggested by diagrams, and there is no better first lesson in drawing than to construct diagrams of cutting angles for plane and cylindrical surfaces.泳
