      "Of course, captain; everything is properly signed, stamped, and legalised."Netherland soldiers and inhabitants of the village bustled about along the opposite river-bank. I shouted as loudly as possible; and when at last I succeeded in drawing their attention, I made them understand that I wanted to be pulled across in the little boat, which in ordinary times served as a ferry. A short consultation took place now on the opposite side, after which a soldier, who clearly possessed a strong voice, came as near as possible to the waterside and, making a trumpet of his two hands, roared:

      Although I had been commanded to return "at once" to Maastricht, I succeeded in having a chat here and there with the inhabitants of Riemst. I had visited the village about eight days ago, but what a change! Then the people assured me that "die Duutschen"[2] were not so bad after all, that they were compelled to do their duty, and were kind to the inhabitants if these were kind to them.130

      53The sudden and varied resistance to line shafts tends to loosen couplings, destroy gearing, and produce sudden strains that are unknown in other cases; and shafting arranged with the usual proportions for transmitting power will soon fail if applied to driving trip-hammers. Rigid connections or metal attachments ace impracticable, and a slipping belt arranged so as to have the tension varied at will is the usual and almost the only successful means of transmitting power to hammers. The motion of trip-hammers is a curious problem; a head and die weighing, together with the irons for attaching them, one hundred pounds, will, with a helve eight feet long, strike from two to three hundred blows a minute. This speed exceeds anything that could be attained by a direct reciprocal motion given to the hammer-head by a crank, and far exceeds any rate of speed that would be assumed from theoretical inference. The hammer-helve being of wood, is elastic, and acts like a vibrating spring, its vibrations keeping in unison with the speed of the tripping points. The whole machine, in fact, must be constructed upon a principle of elasticity throughout, and in this regard stands as an exception to almost every other known machine. The framing for supporting the trunnions, which one without experience would suppose should be very rigid and solid, is found to answer best when composed of timber, and still better when this timber is laid up in a manner that allows the structure to spring and [107] yield. Starting at the dies, and following back through the details of a trip-hammer to the driving power, the apprentice may note how many parts contribute to this principle of elasticity: First—the wooden helve, both in front of and behind the trunnion; next—the trunnion bar, which is usually a flat section mounted on pivot points; third—the elasticity of the framing called the 'husk,' and finally the frictional belt. This will convey an idea of the elasticity required in connecting the hammer-head with the driving power, a matter to be borne in mind, as it will be again referred to.I was greatly astonished to see a little old man sitting by his house, while all those in the neighbour118hood were burning. His own dwelling had escaped without much damage, and was only hit by rifle bullets. He told me that his family had fled, his son with wife and all children but one, a small boy. At length he left also, but had lost his way outside the town, and returned to his house, where the Germans "allowed" him to remain. I considered that I might after all sleep better in that house than yonder among the soldiers, and asked the little man whether he would put me up for the night. He did not object at all; but in spite of my pressing, he refused absolutely to accept any payment.


      "7. Colleaux, senator.In Liège things were no longer so depressing as at the time of my first visit. There was some traffic in the streets, and by order of the German authorities the shops had been reopened.This terrible tragedy took place at scarcely six yards from the Netherland frontier, for the burgo101master's house stands by a road half Belgian and half Netherland. The Netherland soldiers who were doing frontier-duty on the latter part had to fly from the mad shooting of the Germans. They hid behind a wall that was quickly full of bullet-holes. The German soldiers spent a considerable time guzzling the burgomaster's wine, which they looted, and afterwards went off in the direction of Tongres.

      He flushed red with anger, and asked the sergeant what it all meant. The latter told the story and I filled in some details.103"No!"


      VISé DESTROYED: A PREMEDITATED CRIMEA second point to be noticed in hammers of this class is the nature of the connection with the driving power. In all cases there will be found an equivalent for the elastic helve of the trip-hammer—either air cylinders, deflecting springs, or other yielding attachments,—interposed between the crank and the hammer-head, also a slipping frictional belt or frictional clutches for driving, as in the case of trip-hammers."Where do you come from?" was his first question.

      5. The obvious means of attaining this independent movement of the valve gear, is by the momentum of some part set in motion by the hammer-drop, or by the force of gravity reacting on this auxiliary agent."Tell me, father," he began, "did you allow this man by your side to stay the night at your house?"On Thursday, August 20th, I decided to go once more in the direction of Tongres. As the Germans had picketed the main road along the Netherland frontier, I made a detour and dragged my bicycle across the mountain near Petit Laney, a very trying job in the stifling heat. From the mountain top I had a beautiful vista, which enabled me to see that near Riemst a large German force was encamped at which I desired to have a look. So I walked down the hill to Canne, where some crofters were trying to get their cattle into The Netherlands. These poor creatures, who usually own two or three head of cattle, had been compelled already to give up half of their stock. From Canne I cut through corn and beetroot fields to the road to Riemst. The first German sentinels were tolerably friendly.


      (1.) What is the difference between geometric and artistic drawing?—(2.) What is the most important operation in making a good drawing?—(3.) Into what three classes can working drawings be divided?—(4.) Explain the difference between elevations and plans.—(5.) To what extent in general practice is the proportion of parts and their arrangement in machines determined mathematically?The terrible thunder of the guns, of both besiegers and besieged, vibrated through the air. In the distance I noticed a couple of men, probably German soldiers, but a pontoon-bridge was nowhere to be seen. After a few minutes, however, I reached a spot where the Meuse makes a short curve, and had scarcely walked round it, when I saw, only a couple of hundred yards away, the bridge in question, across which a long train of vehicles was passing, loaded with victuals, hay, straw, etc.

      There are also a large number of conventional phrases and endless technicalities to be learned, and to write them will assist in committing them to memory and decide their orthography."Not? Oh! they are sure to do it. All the villages are burning already. The smoke suffocates us here. In Bressoux there is not a house left standing, and in other villages all civilians have been killed, men, women, and children. Not even the tiniest babies escaped.... Oh!... and now it is Liège's turn!"To learn to chip and file is indispensable, if for no other purpose, to be able to judge of the proficiency of others or to instruct them. Chipping and filing are purely matters of hand skill, tedious to learn, but when once acquired, are never forgotten. The use of a file is an interesting problem to study, and one of no little intricacy; in filing across a surface one inch wide, with a file twelve inches long, the pressure required at each end to guide it level may change at each stroke from nothing to twenty pounds or more; the nice sense of feeling which determines this is a matter of habit acquired by long practice. It is a wonder indeed that true surfaces can be made with a file, or even that a file can be used at all, except for rough work.

      "Sister," I said, "I am a cousin of S?ur Eulalie, and should like to see her, to know how she is and take her greetings to her family in The Netherlands."VISé DESTROYED: A PREMEDITATED CRIME
