ENGLISH 苍井空无码作品在线云播"The Reverend Head has been notified already ten times that he would be shot, and he is frequently being arrested for alleged shooting from the building. This shooting is actually done by German soldiers alone, who are loafing and looting, as I myself noticed a short time ago. The Head took me to a room where an old man of ninety, who had just received the extreme unction, lay dying. By his side sat a broken-hearted little old woman, his wife. This old man had been taken prisoner with other men of Vis, and forced to work at a new bridge. The poor fellow broke down under the strain; it cost him his life."A proof of this last proposition is found in the fact that a thorough latheman will perform nearly as much work and do it as well on an old English lathe with plain screw feed, as can be performed on the more complicated lathes of modern construction; but as economy of skill is sometimes an equal or greater object than a saving of manual labour, estimates of tool capacity should be made accordingly. The main points of a lathe, such as may most readily affect its performance, are firsttruth in the bearings of the running spindle which communicates a duplicate of its shape to pieces that are turned,second, coincidence between the line of the spindle and the movement of the carriage,third, a cross feed of the tool at a true right angle to the spindle and carriage movement,fourth, durability of wearing surfaces, especially the spindle bearings and sliding ways. To these may be added many other points, such as the truth of feeding screws, rigidity of frames, and so on, but such requirements are obvious.

Seventh.There is no waste of power by slipping belts or other frictional contrivances to graduate motion; and finally, there is no machinery to be kept in motion when the hammer is not at work."The burgomaster informs the population that any utterance contrary to the regulations will be severely punished.As remarked in the case of other machines treated of, there is no use of describing the mechanism of trip-hammers; it is presumed that every engineer apprentice has seen trip-hammers, or can do so; and the plan here is to deal especially with what he cannot see, and would not be likely to learn by casual observation.

Grinding, no doubt, if traced to the principles that lie at the bottom, is nothing more than a cutting process, in which the edges employed are harder than any material that can be made into cutters, the edges firmly supported by being imbedded into a mass as the particles of sand are in grindstones, or the particles of emery in emery wheels.It is exceedingly difficult for an apprentice engineer, without experimental knowledge, to choose plans for his own education, or to determine the best way of pursuing such plans when they have been chosen; and there is nothing that consumes so much time, or is more useless than attempting to make original designs, if there is not some systematic method followed.Crowds of soldiers moved through the main streets, revelling, shouting, screaming in their mad frenzy of victors. They sat, or stood, or danced in the cafs, and the electrical pianos and organs had been started again "by order." Doors and windows were opened wide, and through the streets sounded forth the song "Deutschland über Alles" (Germany before all other), which affected the inhabitants as a provocation and a challenge. Oh! one could41 see so clearly how thousands of citizens suffered from it, how they felt hurt in their tenderest sentiments. Dull and depressed they stared in front of them, and whenever their set features relaxed, it was a scornful grin.

I went to bed early, for that day I had again walked from Maastricht to Lige. My little bedroom was quite in the roof of the house, and had evidently been used by a servant.This he had done. Already for many days he had treated several officers to his best claret.

Inventions in machine improvement, no matter what their nature, must of course consist in and conform to certain fixed modes of operating, and no plan of urging the truth of a proposition is so common, even with a chance inventor, as to trace out the 'principles' which govern his discovery."Where is that knife?" Von Manteuffel asked the sergeant who had fetched my belongings.Marine and railway engineering have engrossed the best talent in the world; investigation and research has been expended upon these subjects in a degree commensurate with their importance, and it would be hard to suggest a single want in the many able text-books that have been prepared upon the subjects. Marine and railway engineering are sciences that may, in a sense, be separated from the ordinary constructive arts, and studied at the end of a course in mechanical engineering, but are hardly [61] proper subjects for an apprentice to take up at the beginning.

Finishing, therefore, it must be borne in mind, is but one among several processes, and that the fitting department is but one out of four or more among which attention is to be divided."5. Van Zuylen, senator.
