THREE:Some hints will now be given relating to apprentice experience in a workshop, such matters being selected as are most likely to be of interest and use to a learner.
THREE:"5. Who undertake to enter into verbal or written communication with persons in the army or the fleet, of the enemy country at war with Germany, about matters relating to the war itself.The gauging system has been no little retarded by a selfish and mistaken opinion that an engineering establishment may maintain peculiar standards of its own; in fact, relics of this spirit are yet to be met with in old machines, where the pitch of screw-threads has been made to fractional parts of an inch, so that engineers, other than the original makers, could not well perform repairing, or replace broken parts.
THREE:From time to time the tour became a break-neck affair, as the mountain roads were wet and muddy after much rain, and at corners we were often in great fear of being hurled down into the depth. It was a wonderfully fine district of green rock, although somewhat monotonous after a time, as it seemed that we were simply moving in a circle, which impression was strengthened by the fact that frequently we passed through tunnels and viaducts which were very alike to one another.
TWO:The man got more and more excited, but then he was more than "half-seas over." The smoke made him cough and he stuck in the middle of his "swine." He made me shudder, and I hastened to pull out a packet of cigarettes, some of which I gave to him and his mates. In consequence the two others became more communicative, and in touching harmony assured me that:
TWO:It is strange, considering the simplicity of construction and the very important office filled by machines for cutting on plane surfaces, that they were not sooner invented and applied in metal work. Many men yet working at finishing, can remember when all flat surfaces were chipped and filed, and that long after engine lathes had reached a state of efficiency and were generally employed, planing machines were not known. This is no doubt to be accounted for in the fact that reciprocal movement, except that produced by cranks or eccentrics, was unknown or regarded as impracticable for useful purposes until late years, and when finally applied it was thought impracticable to have such movements operate automatically. This may seem quite absurd to even an apprentice of the present time, yet such reciprocating movement, as a mechanical problem, is by no means so simple as it may at first appear.
