ENGLISH ²¨¶àsw146CHAPTER IIf asked for advice as to the most important object for an apprentice to aim at in beginning his fitting course, nine out of ten experienced men will say, "to do work well." As power is measured by force and velocity, work is measured by the two conditions of skill and time. The first consideration being, how well a thing may be done, and secondly, in how short a time may it be performed; the skill spent on a piece of work is the measure of its worth; if work is badly executed, it makes no difference how short the time of performance has been; this can add nothing to the value of what is done although the expense is diminished."4. Armand Flchet, senator.
6. Handling material in machine construction is one of the principal expenses to be dealt with; each time a piece is moved its cost is enhanced, and usually in a much greater degree than is supposed.An engine lathe is for many reasons called the master tool in machine fitting. It is not only the leading tool so far as performing a greater share of the work; but an engine lathe as an organised machine combines, perhaps, a greater number of useful and important functions, than any machine which has ever been  devised. A lathe may be employed to turn, bore, drill, mill, or cut screws, and with a strong screw-feed may be employed to some extent for planing; what is still more strange, notwithstanding these various functions, a lathe is comparatively a simple machine without complication or perishable parts, and requires no considerable change in adapting it to the various purposes named.
These various lathes, although of a widely varied construction and adapted to uses more or less dissimilar, are still the engine lathe either with some of its functions omitted to simplify and adapt it to some special work, or with some of the operative parts compounded to attain greater capacity.Fourth. The arrangement of the parts of a combination machine have to be modified by the relations between them, instead of being adapted directly to the work to be performed.

The process of milling, which has been so extensively adopted in the manufacture of guns, watches, sewing-machines, and similar work in America, has, on principles explained in the chapter on milling, enabled a system of gauging which it is difficult to comprehend without seeing the processes carried on. And so important is the effect due to this duplicating or gauging system, that several important branches of manufacture have been controlled in this way, when other elements of production, such as the price of labour, rent, interest, and so on, have been greatly in favour of countries where the trying system is practised.I took the liberty to explain to the officer that the man did not understand him, and stated that he did not know me.
During the night only a few houses were burnt down; the general destruction followed the next morning, Sunday, August 16th, and just as I reached the little town the flames were raging all over the place in a fierce blaze.Milling tools large enough to admit of detachable cutters being employed, are not so expensive to maintain as solid tools. Edge movement can sometimes be multiplied in this way, so as to greatly exceed what a single tool will perform.Near Haccourt, by the bank of the Meuse, I noticed a terrible glare of fire and dense smoke. It was an alarming sight, and made me fear the direst things. I considered for a moment whether I should go there or not, fearing that I had already taxed my nerves too much. Yet, I made up my mind to go, and by a side-way got to the Meuse, near Vis. German engineers were busy here laying telephone wires, and an officer stopped me, threatening me with his revolver. It was obvious that they were no longer accustomed to see civilians on that road. After having examined my passport and seeing that I was a Netherland journalist, he became very friendly, and politely urged me not to go farther.
"Ah well, you come from The Netherlands; tell me whether it is true that you have let the Germans through, allowing them to ravish us? Tell me whether this is true?"85

The adaptation, endurance, and cost of machines in designing become resolved into problems of movements, the arrangement of parts, and proportions.Two soldiers now took everything I had in my pockets, even my watch and my purse. This brought also to light a German map of Belgium, with a stamp "For military use only." I was told in a gruff voice that this was a highly suspicious thing, and that they could not understand how it got into my possession. I replied quite coolly that I had bought the thing in Aix-la-Chapelle for one mark, where it could be had in many shops, and that the words "For the military only" merely revealed the shrewd German commercial instinct, which knows that people always like to possess things which are not meant for them.The next morning at six I was out and about again. I had not been able to get any breakfast, for the people themselves had nothing. The Germans had called at all the hotels and shops requisitioning everything in stock to feed the thousands who had invaded Lige like so many locusts. The inhabitants practically starved during those days, and carefully saved up bits of bread already as hard as bricks. It was a good thing that the night before I had eaten something at the nunnery, for although at a shop I offered first one, and later on two francs for a piece of bread, I could not get any.
It has been already remarked that the boldness of young engineers is very apt to be inversely as their experience, not to say their want of knowledge, and it is only by a strong and determined effort towards conservatism, that a true balance is maintained in judging of new schemes.As darkness was coming on I asked him whether it was not dangerous to pass the night in the house of that little old man, whom I mentioned above. He saw nothing dangerous in it, as by far the greater part of the town was deserted, and no attack need be feared.
