      "Yes, sir."Lathes in common use for machine fitting are screw-cutting engine lathes, lathes for turning only, double-geared, single-geared, and back-geared lathes, lathes for boring, hand-lathes, and pulley-turning lathes; also compound lathes with double heads and two tool carriages."Bear up, lad! Keep courage; it will soon be different."

      �As I felt myself one with the population, I uncovered my head and enthusiastically joined in the cry: "Au revoir! Au revoir!"A learner should, in fact, consider the application and operative conditions of gearing as one of the main parts of the subject, and the geometry or even the construction of wheels as subsidiary; in this way attention will be directed to that which is most difficult to learn, and a part for which facilities are frequently wanting. Gearing may be classed into five modifications—spur wheels, bevel wheels, tangent wheels, spiral wheels, and chain wheels; the last I include among gearing because the nature of their operation is analogous to tooth wheels, although at first thought chains seem to correspond more to belts than gearing. The motion imparted by chains meshing over the teeth of wheels is positive, and not frictional as with belts; the speed at which such chains may run, with other conditions, correspond to gearing.

      There is nothing in the construction or operation of milling machines but what will be at once understood by a learner who sees them in operation. The whole intricacy of the process lies in its application or economic value, and but very few, even among the most skilled, are able in all cases to decide when milling can be employed to advantage. Theoretical conclusions, aside from practical experience, will lead one to suppose that milling can be applied in nearly all kinds of work, an opinion [143] which has in many cases led to serious mistakes.103Pneumatic machinery, aside from results due to the elasticity of air, is analogous in operation to hydraulic machinery.

      �Of a heavy heart, however, there was not a trace. In the previous chapter I described how beastly they behaved during the destruction of Visé; how the soldiers drank immoderate quantities of alcohol, and then jeered at the wretched refugees; how they indulged in unmitigated vandalism, and wrecked by hand things of which they knew that by and by would be destroyed by fire."Oh, go on!" I answered. "I don't think that I need fear anything of the kind. I am in any case a Netherlander!"

      A little farther away they were still busy with Lierce, but excepting these four, all the forts were now taken by the Germans. I stood there for a moment, gazing at these cannon, the presence of which was clearly unknown to the Belgians, for their artillery took no notice of them. Only the day before these guns had started shelling the forts, and on the evening of August 15th they had silenced two of them; but Loncin kept up the fight.CHAPTER XL. INVENTION.�

      I met a doctor at this nunnery, who told me highly important news, but in whispers, because in these days "even walls have ears": the Allies had gained great victories over the Germans. As he saw by the expression of my face that I did not believe off-hand all he told, he became still more impressive in manner, and produced a paper, from which he recited:—�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.

      Immediately after the church was set on fire, the dean was arrested, as well as the burgomaster and five reverend sisters. These last-mentioned had been in prison a fortnight, when at last the Germans discovered that the little sisters were of German nationality. The Very Reverend Dean had been treated very badly during his captivity.��

      When we came to Jumet, a suburb of Charleroi, and a prosperous place with flourishing factories, we found the whole town wrecked.... Nearly all the houses were burned immediately after the occupation by the Germans, and many inhabitants were killed, of course under the pretext that they had been shooting.��
