      In considering pneumatic machinery there are the following points to which attention is directed:—My little protégée was, however, soon very tired and complained that her feet ached. I had to carry her for nearly a mile and a half before we arrived at the Netherland Custom House, where I left her behind, as she was now safe. I went on to Maastricht alone, wired to my paper, and then saw the worried, but soon extremely happy parents of the little girl. They went at once to the Netherland frontier to take their child home.�

      �The mission house had become a sanctuary for a good many people. As bread was lacking, two brothers fried pancakes all day long and distributed them among the numberless persons who asked for food. Among these were people who a few days earlier belonged to the well-to-do, but who saw their business, in which often more than their own capital was invested, wrecked by fire, and were now obliged to appeal to the charity of these monks. Indeed during the first weeks after that terrible event many starved, and I assisted often at the distribution of the pancakes, because they were short-handed.�



      During the early days of the war the papers published a report, of German origin, that Visé had been destroyed because francs-tireurs had appeared. I was therefore not a little amazed when, arriving there on August 8th, I found the townlet entirely undamaged, and even the German military admitted that they had not heard a word about francs-tireurs.The Liège people were already up and about, and wandered through the streets full of fear, for all sorts of rumours were heard—that civilians were murdered, the town was to be burned down, and that a start would be made very soon. As they looked at those burning hamlets yonder they believed the rumours, and went nearly mad for fear; the men as well as the women could not help46 themselves, and wept. During the night various posters were stuck on the walls about military action. The following is the translation of one of these:—The importance of standard dimensions, and the effect which a system of gauging may have in the construction of machines, will be a matter of some difficulty for a learner to understand. The interchangeability of parts, which is the immediate object in employing gauges, is plain enough, and some of the advantages at once apparent, yet the ultimate effects of such a system extend much farther than will at first be supposed.

      The general expatiated once more on the francs-tireurs of Louvain, and asked me to explain in my papers without fail that the citizens had to thank themselves for what had happened. The sergeant who had taken me to him was ordered to escort me, that I might not have any further trouble with the soldiers in the city.�"I don't know yet. The things I see ... and ... of course that cannot do harm to the German army."


      �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.


      Pencilling is the first and the most important operation in draughting; more skill is required to produce neat pencil-work than to ink in the lines after the pencilling is done.CHAPTER VDrilling differs in principle from almost every other operation in metal cutting. The tools, instead of being held and directed by guides or spindles, are supported mainly by the bearing of the cutting edges against the material.

      �The wounded civilians had been put up in the small schoolrooms. Some of them must soon die. Some had burns, but most of them were hit the previous night during the mad outbreak, the mad shooting of the drunken and riotous Germans. In another room a number of old women were crowded together, who had to fly but could not walk all the way to the Netherland frontier.�




      To sum up, it is supposed to have been determined by inductive reasoning, coupled with some knowledge of mechanics, that a steam hammer, to give a dead blow, requires the following conditions in the valve gearing:An old smith who has stood at the forge for a score of years will take the same interest in tempering processes that a novice will. When a piece is to be tempered which is liable to spring or break, and the risk is great, he will enter upon it with the same zeal and interest that he would have done when learning his trade.�
