      Mr. Derricks lived at Roelanche, but with his wife and seven children had fled for security to Canne, where he was hospitably received in Mr. Poswick's, the burgomaster's, house.いい榈偿(1.) In what respect are air and water like belts and gearing, as means to transmit power?—(2.) What are some of the principal advantages gained by employing air to operate railway brakes?—(3.) Name some of the advantages of centralising motive power.—(4.) Are the conditions of working an engine the same whether air or steam is employed?イベBetween my tours through the Liège district I made a trip in the direction of Tongres, because I wanted to know what had become of all those Germans who had crossed the Meuse near Lixhe. It was remarkable to notice how friendly the Flemings of that district behaved with regard to the Germans. Although they criticised the violation of the country's neutrality sharply, and every family was proud of the sons who had taken up arms in defence of their Fatherland, yet they judged quite kindly the German soldiers who passed through their district. I often heard expressions full of pity toward those men, who could not help themselves, but were compelled to do whatever their superiors commanded them.イテ

      "They were all unrecognisable, their faces were black from smoke, their uniforms in rags, their hands covered with blood. The general was put on a stretcher, and carried outside the fort across the heaps of obstacles; there he was attended to by a surgeon. He had lost consciousness. As soon as he recovered it, he pressed the hands of two Belgian officers. 'It is all over; there is nothing left to defend. But we did our utmost courageously.'しバ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.谳笑dc堡CHAPTER XXXIV. BORING AND DRILLING.昆イ辘ズい

      5. The lubrication of surfaces working under air pressure, such as the pistons and valves of engines.ズ英ぅせいLOUVAIN DESTROYED兢ュイēフLeaving out problems of mechanism in forging machines, the adaptation of pressing or percussive processes is governed mainly by the size and consequent inertia of the pieces acted upon. In order to produce a proper effect, that is, to start the particles of a piece throughout its whole depth at each blow, a certain proportion between a hammer and the piece acted upon must be maintained. For heavy forging, this principle has led to the construction of enormous hammers for the performance of such work as no pressing machinery can be made strong enough to execute, although the action of such machinery in other respects would best suit the conditions of the work. The greater share of forging processes may be performed by either blows or compression, and no doubt the latter process is the best in most cases. Yet, as before explained, machinery to act by pressure is much more complicated and expensive than hammers and drops. The tendency in practice is, however, to a more extensive employment of press-forging processes.げ郡氯

      (1.) In comparing steam-hammers with trip or crank hammers what mechanism does steam supplant or represent?—(2.) What can be called the chief distinction between steam and other hammers?—(3.) Under what circumstances is an automatic valve motion desirable?—(4.) Why is a dead or uncushioned blow most effective?—(5.) Will a hammer operate with air the same as with steam?ヤ撺%イぉ4. To cause a movement of the valve after the hammer stops there must be an intermediate agent, that will continue to [163] act after the movement of the hammer drop has ceased.イ尢讠崇心米�ざ籁イ

      An apprentice in entering the workshop should avoid everything tending to an appearance of fastidiousness, either of manner or dress; nothing is more repulsive to workmen, and it may be added, nothing is more out of place in a machine shop than to divide one's time between the work and an attempt to keep clean. An effort to keep as neat as the nature of the work will admit is at all times right, but to dress in clothing not appropriate, or to allow a fear of grease to interfere with the performance of work, is sure to provoke derision.颔�熹─Machine-drawing may in some respects be said to bear the same relation to mechanics that writing does to literature; persons may copy manuscript, or write from dictation, of what they do not understand; or a mechanical draughtsman may make drawings of a machine he does not understand; but neither such writing or drawing can have any value beyond that of ordinary labour. It is both necessary and expected that a draughtsman shall understand all the various processes of machine construction, and be familiar with the best examples that are furnished by modern practice.欹ぅ居粘

      It is evident that when the parts of a machine are joined together, each piece which has contact on more than one side must have specific dimensions; it is farther evident that as many of the joints in a machine as are to accommodate the exigencies of construction must be without space, that is, they represent continued sections of what should be solid material, if it were possible to construct the parts in that manner. This also demands specific dimensions.い∶So at last the lock of the heavy door screeched, and I was admitted. I noticed that about a score of sisters had gathered behind the gate and were anxiously discussing the "strange occurrence." My meeting with S?ur Eulalie, however, was so cordial that the good nuns lost all anxiety, and I was taken inside accompanied by nearly all the inmates of the convent.单いイぅ颏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.瞟ぐいい

      May all the nations of the world after the war collaborate to compensate Louvain for her martyrdom, see that this city shall be restored to her former, happy prosperity, and get a library which approaches as much as possible the one she lost. The Germans can probably do their part by investigating where the motor-cars went which left the Halls on that wretched Tuesday night, heavily laden with books.芸"On which paper?"ゥ由イ¥罱ぉ�瑜ボリパ蜘

      A learner will no doubt wonder why sand is used for moulding, instead of some more adhesive material like clay. If he is not too fastidious for the experiment, and will apply a lump of damp moulding sand to his mouth and blow his breath through the mass, the query will be solved. If it were not for the porous nature of sand-moulds they would be blown to pieces as soon as the hot metal entered them; not only because of the mechanical expansion of the gas, but often from explosion by combustion. Gas jets from moulds, as may be seen at any time when castings are poured, will take fire and burn the same as illuminating gas.尚さ贩耙�レ趣ゅい长�そゑろ妞澶ユ

      This he had done. Already for many days he had treated several officers to his best claret.ⅴいいい扭殂A milling tool with twenty edges should represent as much wearing capacity as a like number of separate tools, and may be said to equal twenty duplicate tools; hence, in cutting grooves, notches, or similar work, a milling tool is equivalent to a large number of duplicate single tools, which cannot be made or set with the same truth; so that milling secures accuracy and duplication, objects which are in many cases more important than speed.巷ぃイЮウI will not consume space to explain the converse of this system of inventing, nor attempt to describe how a chance schemer would proceed to hunt after mechanical expedients to accomplish the valve movement in the example given.证伐犯
