ENGLISH 小泽园有几部步兵"Are they tolerably kind?"
"Where is that knife?" Von Manteuffel asked the sergeant who had fetched my belongings.Those wide carts had passed us now, and we could proceed slowly. The bridge led to a farmhouse with tall trees and underwood. They took me to the right, to a densely overgrown spot, where a clearing had been made amidst some smaller shrubs. In the centre stood a table covered with a shining white cloth, and a goodly number of wine-bottles and glasses. Half a dozen officers in fine uniforms, gilt collars and epaulettes, were seated around it.
When a piece is placed on an anvil, and struck on the top side with a certain force, the bottom or anvil side of the piece does not receive an equal force. A share of the blow is absorbed by the inertia of the piece struck, and the effect on the bottom side is, theoretically, as the force of the blow, less the cushioning effect and the inertia of the pieces acted upon.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.No subject connected with mechanics has been more thoroughly investigated than that of gearing. Text-books are replete with every kind of information pertaining to wheels, at least so far as the subject can be made a mathematical one; and to judge from the amount of matter, formul?, and diagrams, relating to the teeth of wheels that an apprentice will meet with, he will no doubt be led to believe that the main object of modern engineering is to generate wheels. It must be admitted that the teeth of wheels and the proportions of wheels is a very important matter to understand, and should be studied with the greatest care; but it is equally important to know how to produce the teeth in metal after their configuration has been defined on paper; to understand the endurance of teeth under abrasive wear when made of wrought or cast iron, brass or steel; how patterns can be constructed from which correct wheels may be cast, and how the teeth of wheels can be cut by machinery, and so on.
They made also sad havoc of the Boulevard de Namur. Many mansions of the aristocracy had been destroyed and many people killed. There were corpses still lying on the Boulevard as I passed, all in a state of decay. The smell was unbearable and the sight loathsome, especially when I saw several drunken soldiers insulting the bodies of these unfortunate people.
This mode of reasoning will lead to proper estimates of the difference in value between good tools and inferior tools; the results of performance instead of the investment being first considered, because the expenses of operating are, as before assumed, usually ten times as great as the interest on the value of a machine.In Louvain I was myself arrested, because a more than half-drunk soldier had accused me of spying and arson! There too I had to listen to all sorts of abuse because I was a franc-tireur. And in spite of all this they tried to extract a promise from me to write against the francs-tireurs!
Screw-cutting is divided into two kinds, one where the blanks or pieces to be threaded are supported on centres, the tools held and guided independently of their bearing at the cutting edges, called chasing; the other process is where the blanks have no axial support, and are guided only by dies or cutting tools, called die-cutting.In the end these stories of the soldiers convinced even the inhabitants that there had been francs-tireurs, but never in the place where they lived, always somewhere else. They could not believe that the Germans could be so cruel and wreck so much property if nothing at all had happened; and when at length the time came that they themselves were obliged to fly, many of them believed that their compatriots who elsewhere acted as francs-tireurs were to blame for all the dire calamities. But if they had had my opportunity to go "elsewhere" and gather information there, they would have been convinced of the untruth, and probably would have heard the name of their own village as90 the scene of the occurrence. That was how rumours and reports got about.Air seems to be the most natural and available medium for transmitting and distributing power upon any general system like water or gas, and there is every probability of such a system existing at some future time. The power given out by the expansion of air is not equal to the power consumed in compressing it, but the loss is but insignificant compared with the advantages that may be gained in other ways. There is no subject more interesting, and perhaps few more important for an engineering student to study at this time, than the transmission of power and the transport of material by pneumatic apparatus.

The term planing should properly be applied only to machines that produce planes or flat surfaces, but the technical use of the term includes all cutting performed in right lines, or by what may be called a straight movement of tools.
I had wished to publish this book a long time ago, because I think it my duty to submit to the opinion of the public the things which I witnessed in the unfortunate land of the Belgians, and where I was present at such important events as an impartial spectator. I call myself an impartial spectator, for if this book be anti-German, it should not be forgotten that the facts give it that tendency.At the Place des Tilleuls fifty men were taken from the crowd at random, escorted to the Meuse, and shot. In the meantime other soldiers went on wrecking, firing, and looting.
