ENGLISH An engineer may direct and control work without a knowledge of practical fitting, but such control is merely a commercial one, and cannot of course extend to mechanical details which are generally the vital part; the obedience that may thus be enforced in controlling others is not to be confounded with the respect which a superior knowledge of work commands.After determining the ultimate objects of an improvement, and laying down the general principles which should be followed in the preparation of a design, there is nothing connected with constructive engineering that can be more nearly brought within general rules than arranging details. I am well aware of how far this statement is at variance with popular opinion among mechanics, and of the very thorough knowledge of machine application and machine operation required in making designs, and mean that there are certain principles and rules which may determine the arrangement and distribution of material, the position and relation of moving parts, bearings, and so on, and that a machine may be built up with no more risk of mistakes than in erecting a permanent structure."To the inhabitants of the City of Louvain

That is not evidence however, for how did they get the information? From my own experience I make bold to say with the greatest confidence that these reports came from German sources only, whereas there was not any ground for them.Only because these wretched people had not promptly obeyed the order of the military to march against the fort in front of the soldiers, Vivignes had been punished, and that morning over forty of the best houses had been set on fire.

They carried all those patients into the cellars on stretchers, and there waited with the nursing staff for the bombardment that had been announced, but never came off.It is well for an apprentice to invent or demonstrate all that he canthe more the better; but as explained in a previous place, what is attempted should be according to some system, and with a proper object. Time spent groping in the dark after something of which no definite conception has been formed, or for any object not to fill an ascertained want, is generally time lost. To demonstrate or invent, one should begin methodically, like a bricklayer builds a wall, as he mortars and sets each brick, so should an engineer qualify, by careful study, each piece or movement that is added to a mechanical structure, so that when done, the result may be useful and enduring.Other soldiers kept on running into the burning houses, carrying out vases, pictures, plate, or small pieces of furniture. They smashed everything on81 the cobbles and then returned to wreck more things that would have been destroyed by the fire all the same. It was a revelry of drunken vandalism. They seemed mad, and even risked being burned alive at this work of destruction. Most of the officers were also tipsy; not one of them was saluted by the soldiers.

Good fitting is often not so much a question of skill as of the standard which a workman has fixed in his mind, and to which all that he does will more or less conform. If this standard is one of exactness and precision, all that is performed, whether it be filing, turning, planing, or drawing, will come to this standard. This faculty of mind can be defined no further than to say that it is an aversion to whatever is imperfect, and a love for what [171] is exact and precise. There is no faculty which has so much to do with success in mechanical pursuits, nor is there any trait more susceptible of cultivation. Methodical exactness, reasoning, and persistence are the powers which lead to proficiency in engineering pursuits.On that occasion the Germans arrested me at about two miles from Tirlemont. Firstly, because I travelled by bicycle, and secondly, because I was accused of having "cooked" one of my passports.

To attain a double effect, and avoid the loss pointed out, Mr Ramsbottom designed what may be called compound hammers, consisting of two independent heads or rams moving in opposite directions, and acting simultaneously upon pieces held between them.

"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?"

It is, of course, very difficult to deal with so complex a subject as the present one with words alone, and the reader is recommended to examine drawings, or, what is better, water-wheels themselves, keeping the above propositions in view.Another peculiar feature in trip-hammers is the rapidity with which crystallisation takes place in the attachments for holding the die blocks to the helves, where no elastic medium can be interposed to break the concussion of the dies. Bolts to pass through the helve, although made from the most fibrous Swedish iron, will on some kinds of work not last for more than ten days' use, and often break in a single day. The safest mode of attaching die blocks, and the one most common, is to forge them solid, with an eye or a band to surround the end of the helve.1. The most economical and effectual mechanism for handling is that which places the amount of force and rate of movement continually under the control of an operator.

It is, of course, very difficult to deal with so complex a subject as the present one with words alone, and the reader is recommended to examine drawings, or, what is better, water-wheels themselves, keeping the above propositions in view."10. Falloise, alderman.
