      "Netherlander or not, it does not matter. Whosoever one be, every civilian is shot down by them."While all the others were denouncing me, one soldier was ready to believe that I was a peaceful foreign journalist, and that all the misunderstanding would disappear the next morning as soon as I should be taken to the commanding officer. He took pity on me, and got a thick soldier's coat for me as cover. I still feel grateful to the man for it! But sleep was out of the question on that wet floor, in the dense fog. When the guard was changed and soldiers came back, or others went, they could not see in the dark where they went, and treated me to a kick against my head or some other part of my body.

      "The powerful German army, victorious in our district, has promised to respect our land and private possessions.The Lige people were already up and about, and wandered through the streets full of fear, for all sorts of rumours were heardthat 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:

      Workshop processes which are capable of being systematised are the most easy to learn. When a process is reduced to a system it is no longer a subject of special knowledge, but comes within general rules and principles, which enable a learner to use his reasoning powers to a greater extent in mastering it.

      He was back in The Netherlands before me.For implements procure two drawing-boards, forty-two inches long and thirty inches wide, to receive double elephant paper; have the boards plain without cleets, or ingenious devices for fastening the paper; they should be made from thoroughly seasoned lumber, at least one and one-fourth inches thick; if thinner they will not be heavy enough to resist the thrust of the T squares.

      The prevailing custom of casting machine frames in one piece, or in as few pieces as possible, leads to a great deal of bar-boring, most of which can be performed accurately enough by boring bars supported in and fed through bearings. By setting up temporary bearings to support boring-bars, and improvising means of driving and feeding, most of the boring on machine frames can be performed on floors or sole plates and independent of boring machines and lathes. There are but few cases in which the importance of studying the principles of tool action is more clearly demonstrated than in this matter of boring; even long practical experience seldom leads to a thorough understanding of the [139] various problems which it involves.Castings are of course sprung by the action of unequal strains, caused by one part cooling or 'setting' sooner than another. That far all is clear, but the next step takes us into the dark. What are the various conditions which induce irregular cooling, and how is it to be avoided?

      (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?

      "Ah, so you are a Netherlander, aren't you? Then we are friends. The Netherlands remains neutral, does she not? What news have you from there; are you already at war with Britain?"General von Buelow says here that he gave his consent to the shooting of about one hundred persons, but I can state with absolute certainty that there were about 400 victims. We must therefore assume that the other 300 were killed without his consent.




      At Vis many men had been commanded to do certain kinds of work, cutting down trees, making of roads, bridges, and so on. Many of them never returned, because they refused to do the humiliating work and were shot. Among these there were even aged people; and I myself stood by the death-bed of a man of ninety, who had been forced to assist in building a bridge, until the poor wretch broke down and was carried to St. Hadelin College, turned into a hospital by Dr. Goffin; there he died.A difficulty which arises in hardening tools is because of the contraction of the steel which takes place in proportion to the change of temperature; and as the time of cooling is in proportion to the thickness or size of a piece, it follows, of course, that there is a great strain and a tendency to break the thinner parts before the thicker parts have time to cool; this strain may take place either from cooling one side first, or more rapidly than another.


      In regard to the use of the T square and set squares, no useful rules can be given except to observe others, and experiment until convenient customs are attained. A beginner should be careful of adopting unusual plans, and above all things, of making important discoveries as to new plans of using instruments, assuming that common practice is all wrong, and that it is left for him to develop the true and proper way of drawing. This is a kind of discovery which is very apt to intrude itself at the beginning of an apprentice's course in many matters besides drawing, and often leads him to do and say many things which he will afterwards wish to recall.The relation between invention and the engineering arts, and especially between invention and machines, will warrant a short review of the matter here; or even if this reason were wanting, there is a sufficient one in the fact that one of the first aims of an engineering apprentice is to invent something; and as the purpose here is, so far as the limits will permit, to say something upon each subject in which a beginner has an interest, invention must not be passed over.
