      When the dimensions and symbols are added to a drawing, the next thing is pattern or catalogue numbers. These should be marked in prominent, plain figures on each piece of casting, either in red or other colour that will contrast with the general face of the drawing. These numbers, to avoid the use of symbols in connection with them, must include consecutively all patterns employed in the business, and can extend to thousands without inconvenience.

      CHAPTER XVI. MACHINERY OF APPLICATION.Is it thinkable that persons in that frame of mind would take up arms and invite the enemy's revenge upon themselves and those near and dear to them, a revenge of which they were so mortally afraid?

      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.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.

      In working with dead blows, no steam is admitted under the piston until the hammer has finished its down stroke, and expended its momentum upon the work. So different is the effect produced by these two plans of operating, that on most kinds of work a hammer of fifty pounds, working with dead blows, will perform the same duty that one of a hundred pounds will, when acting by elastic or cushioned blows.


      Inventions in machine improvement, no matter what their nature, must of course consist in and conform to certain fixed modes of operating, and no plan of urging the truth of a proposition is so common, even with a chance inventor, as to trace out the 'principles' which govern his discovery.

      "Last night a shooting affray took place. There is no evidence that the inhabitants of the towns had any arms in their houses, nor is there evidence that the people took part in the shooting; on the contrary, it seems that the soldiers were under the influence of alcohol, and began to shoot in a senseless fear of a hostile attack.The dear lady rapped it out in such a decided tone of voice that I desisted. I told my trouble to the proprietor of a caf where I took a glass of beer; he, examining my papers, placed confidence in me, and got me a rickety thing, for which I paid twenty-two francs.

      And during these first days of the war I had not met a single person who was able to settle down quietly in the existing circumstances, not a single person in whom anger and fury subdued fear and terror.Machinery subjected to destructive wear, and to be operated at a distance from machine shopslocomotive engines for exampleif not constructed with standard dimensions, may, by the detention due to repairing, cause a loss and inconvenience equal to their value; if a shaft wheel bearing, or even a fitted screw bolt is broken, time must be allowed to make the parts new; and in order to fit them, the whole machine, or such of its details as have connection with the broken parts, must be taken to a shop in order to fit by trial.

      "That is a Netherland girl, sir, who was staying at her aunt's at Lige ... I mean to say at Vis, and whom I take now with me to Maastricht."Very large divisions marched from Vis to the pontoon bridge in the direction of Tongres. After the Lige 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 Vis 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.

      To urge the necessity of learning practical fitting as a part of an engineering education is superfluous. A mechanical engineer who has not been "through the shop" can never expect to attain success, nor command the respect even of the most inferior workmen; without a power of influencing and controlling others, he is neither fitted to direct construction, nor to manage details of any kind connected with engineering industry. There is nothing that more provokes a feeling of resentment in the mind of a skilled man than to meet with those who have attempted to qualify themselves in the theoretical and commercial details of engineering work, and then assume to direct labour which they do not understand; nor is a skilled man long in detecting an engineer of this class; a dozen words in conversation upon any mechanical subject is generally enough to furnish a clue to the amount of practical knowledge possessed by the speaker.
