      "In and round about Visé people sleep in their cellars, as they are threatened frequently that the town will be set on fire.""You see, sir, the bridge across the Meuse has been destroyed, and in order to get back I had to walk first towards ... towards ... Liège ... and ... and ... and then they ferried me over somewhere down there, and told me that I had to go along the canal to get to Maastricht."The successful application of the pneumatic system at the Mont Cenis Tunnel in Italy, and at the Hoosac Tunnel in America, has demonstrated the value of the system where the air not only served to transmit power to operate the machinery but to ventilate the mines at the same time. Air brakes for railway trains are another example illustrating the advantages of pneumatic transmission; the force being multiplied at the points where it is applied, so that the connecting pipes are reduced to a small size, the velocity of the air making up for a great force that formerly had to be communicated through rods, chains, or shafts. The principal object attained by the use of air to operate railway brakes is, however, to maintain a connection throughout a train by means of flexible pipes that accommodate themselves to the varying distance between the carriages. Presuming that the flow of air in pipes is not materially impeded by friction or angles, and that there will be no difficulty in maintaining lubrication for pistons or other inaccessible parts of machinery when driven by air, there seems to be many reasons in favour of its use as a means of distributing power in manufacturing districts. The diminished cost of motive power when [56] it is generated on a large scale, and the expense and danger of maintaining an independent steam power for each separate establishment where power is employed, especially in cities, are strong reasons in favour of generating and distributing power by compressed air, through pipes, as gas and water are now supplied.

      Very large divisions marched from Visé to the pontoon bridge in the direction of Tongres. After the Liège forts had been taken the bridge might be passed in perfect safety. All day long troops came along that road without interruption. I could quite see that the soldiers who were at Visé the previous day, and brought about the conflagration, were gone, for they had left their traces behind. All along the road lay parts of bicycles, shoes, instruments, toys, and so on, everything new77 and evidently looted from the shops. Very valuable things were among them, everything crushed and smashed by the cavalry horses, the clumsy munition and forage waggons, or the heavy wheels of the guns.They did not understand, of course, that poor Belgium would have liked nothing better than to remain neutral also.

      I stood near the spot where the ferry-boat used to take people across; but to cross was now out of the question, for any one alighting on the opposite side would be landed in the scorching glare. Therefore, I returned to Lixhe, where I might try to cross the river by the pontoon-bridge, and get to Visé along the other bank of the Meuse.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.


      Forges, pneumatic machinery for blast, machinery for handling large pieces, and other details connected with forging, are easily understood from examples.By classifying these processes, it will be seen that there is in all but a few functions to be performed by machines, and that they all act upon a few general principles. Engineering tools employed in fitting are, for example, all directed to the process of cutting. Planing machines, lathes, drilling machines, and shaping machines are all cutting machines, acting upon the same general plan—that of a cleaving wedge propelled in straight or curved lines.

      The following propositions in regard to tempering, comprehend the main points to be observed:56Keeping 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.


      When a tool is guided by turning on points, the movement is perfect, and the straightness or parallelism of holes bored in this manner is dependent only on the truth of the carriage movement. This plan of boring is employed for small steam cylinders, cylindrical valve seats, and in cases where accuracy is essential."I refuse to sell 'bikes' to Germans."

      It is easy to learn "how" to draw, but it is far from easy to learn "what" to draw. Let this be kept in mind, not in the way of [79] disparaging effort in learning "how" to draw, for this must come first, but in order that the objects and true nature of the work will be understood.I THINK that there is no better occasion to deal with the question whether there was a franc-tireur-guerilla in Belgium than after the chapter on the destruction of Visé.When I told the doctor that I had to go to the station, he explained to me how I could get there without walking across red hot cinders, and I followed his advice. I walked through quarters which used to be the pride of the city, but were now turned into heaps of rubbish.


      And by my side stood officers and soldiers raging and cursing. To them came the returning men, blood running along their faces from insignificant wounds, and they bawled and bellowed, and thundered with a thousand curses that they wanted to go back and try again. How ghastly they rolled their eyes in frenzied excitement! Some pointing at me asked the officer who I was, and he explained. Then I had to listen to endless imprecations against the civilian population of Belgium, who, according to them, consisted entirely of francs-tireurs, who all of them deserved to be shot, and to have their61 houses burned down. To repeat the coarse words which they sputtered out in their rage would only cause disgust."German sappers and other military men cleared away the dead and the wounded. They also discovered General Leman, whose orderlies, who had a miraculous escape from death, were already busy in rescuing him from underneath the ruins.There is nothing more interesting, or at the same time more useful, in the study of mechanics, than to analyse the action of cutting machines or other machinery of application, and to ascertain in examples that come under notice whether the main object of a machine is increased force, more accurate guidance, or greater speed than is attainable by hand operations. Cutting machines as explained may be directed to either of these objects singly, or to all of them together, or these objects may vary in their relative importance in different operations; but in all cases where machines are profitably employed, their action can be traced to one or more of the functions named.

      CHAPTER ITo attain a double effect, and avoid the loss pointed out, Mr Ramsbottom designed what may be called compound hammers, consisting of two independent heads or rams moving in opposite directions, and acting simultaneously upon pieces held between them.

      They sang and shouted and waved their arms. Most of them carried bottles full of liquor, which they put to their mouths frequently, smashed them on the ground, or handed them to their comrades, when unable to drink any more themselves. Each of a troop of cavalry had a bottle of pickles, and enjoyed them immensely.
