ENGLISH ²Ô¾®¿ÕavÖÖ×ÓÑ¸À×mp4On the afternoon of the 23rd the hostile troops entered the town, and on that day the inhabitants had not to suffer, excepting from requisitions made. But the following evening it was suddenly on fire at various spots, and the soldiers began to shoot in all directions, making many victims. Before setting the houses on fire, with a liberal use of the lozenges mentioned already, the usurpers ransacked them and removed numerous pieces of valuable furniture. The Place d'Armes, the Place Lopold, the Rue St. Nicolas, Rue Rogier, and the Avenue de la Plante were almost entirely reduced to ashes. With the town-hall many valuable pictures were destroyed. The day following the conflagration they left off shooting at last, but the looting went on for days more.
In this way I got into conversation with a middle-aged lady. Her husband had been shot, and she got a bullet in her arm, which had to be amputated in consequence. The poor creature had lost all courage, and lived on her nerves only. It was remarkable to hear this father find the right words, and succeed in making her calm and resigned.138 Before she left us, she had promised that for her children's sake she would do all in her power to control herself.The soldiers lying round about me, and those in other parts of the station, got up, shouting, "There are the British," and ran towards the arriving trains. They jeered at the beaten enemies in all sorts of vulgar and filthy words, which made the German129 enthusiasm absolutely lacking in chivalry. Eight trains with captured British arrived during that night.
Thus it went on all day long: motors and other conveyances travelled to and fro between the battle-17fields and hospitals at Maastricht; fugitives moved about in streets and squares, upsetting each other more and more by fantastic stories."Yes, sir."
(1.) Why are shaping machines better adapted than planing machines for planing slots, key-ways, and so on?(2.) What objects are gained by a quick return motion of the cutter bar of shaping machines?At Vis many men had been commanded to do certain kinds of work, cutting down trees, making of roads, bridges, and so on. Many of them never returned, because they refused to do the humiliating work and were shot. Among these there were even aged people; and I myself stood by the death-bed of a man of ninety, who had been forced to assist in building a bridge, until the poor wretch broke down and was carried to St. Hadelin College, turned into a hospital by Dr. Goffin; there he died.
Another principle in planing machines which deserves notice is the manner of driving carriages or platens; this is usually performed by means of spur wheels and a rack. A rack movement is smooth enough, and effective enough so far as a mechanical connection between the driving gearing and a platen, but there is a difficulty met with from the torsion and elasticity of cross-shafts and a train of reducing gearing. In all other machines for metal cutting, it has been a studied object to have the supports for both the tools and the material as rigid as possible; but in the common type of planing machines, such as have rack and pinion movement, there is a controversion of this principle, inasmuch as a train of wheels and several cross-shafts constitute a very effective spring between the driving power and the point of cutting, a matter that is easily proved by planing across the teeth of a rack, or the threads of a screw, on a machine arranged with spur wheels and the ordinary reducing gearing. It is true the inertia of a platen is interposed and in a measure overcomes this elasticity, but in no degree that amounts to a remedy.Die-cutting produces screws which may not be true, but are still sufficiently accurate for most uses, such as clamping and joining together the parts of machinery or other work.CHAPTER XX. GENERALISATION OF SHOP PROCESSES.
By what accident had I not been disturbed? The height, perhaps, at which my miserable little garret-room was situated.

The lathe as a tool for producing heliacal forms would occupy a prominent place among machine tools, if it were capable of performing no other work; the number of parts of machinery which have screw-threads is astonishing; clamping-bolts to hold parts together include a large share of the fitting on machinery of all kinds, while screws are the most common means for increasing power, changing movements and performing adjustments.My little protge was, however, soon very tired and complained that her feet ached. I had to carry her for nearly a mile and a half before we arrived at the Netherland Custom House, where I left her behind, as she was now safe. I went on to Maastricht alone, wired to my paper, and then saw the worried, but soon extremely happy parents of the little girl. They went at once to the Netherland frontier to take their child home.All the wounded were Roman Catholics, and as they saw the approaching priest, they implored him in a loud voice to give them absolution of sins, some making an act of contrition. The priest was unable to come near each of them, and therefore called out in a loud voice: "My Jesus, be merciful!" He then gave them all absolution of sins. But as he kneeled down to perform this sacred task, a hostile bullet whizzed past his ear, and several soldiers who ran by aimed at him, so that he had to seek safety behind a tree. I saw with my own eyes five bullet-holes in the tree that was pointed out to me.
The action of steam-hammers may also be divided into what is termed elastic blows, and dead blows.Fifth.The range and power of the blows, as well as the time in which they are delivered, is controlled at will; this constitutes the greatest distinction between steam and other hammers, and the particular advantage which has led to their extended use.
