ONE:Founding and casting relate to forming parts of machinery by pouring melted metal into moulds, the force of gravity alone being sufficient to press or shape it into even complicated forms. As a process for shaping such metal as is not injured by the high degree of heat required in melting, moulding is the cheapest and most expeditious of all means, even for forms of regular outline, while the importance of moulding in producing irregular forms is such that without this process the whole system of machine construction would have to be changed. Founding operations are divided into two classes, known technically as green sand moulding, and loam or dry sand moulding; the first, when patterns or duplicates are used to form the moulds, and the second, when the moulds are built by hand without the aid of complete patterns. Founding involves a knowledge of mixing and melting metals such as are used in machine construction, the preparing and setting of cores for the internal displacement of the metal, cooling and shrinking strains, chills, and many other things that are more or less special, and can only be learned and understood from actual observation and practice.For implements procure two drawing-boards, forty-two inches long and thirty inches wide, to receive double elephant paper; have the boards plain without cleets, or ingenious devices for fastening the paper; they should be made from thoroughly seasoned lumber, at least one and one-fourth inches thick; if thinner they will not be heavy enough to resist the thrust of the T squares. TWO:"Oh, go on!" I answered. "I don't think that I need fear anything of the kind. I am in any case a Netherlander!"

ONE:Behind his paper Prout gave a start. Here was a case where the pursuit of one crime led to another. The leader of the gang of thieves had large orange coloured freckles on his hand the same as Prout had seen on the hands of the victim of the Corner House tragedy. TWO:That was a relief! I began to translate, taking the liberties to which every translator is entitled. And I succeeded in making a favourable impression by censoring my own manuscript.

ONE:These remarks upon hammers are not introduced here as a matter of curiosity, nor with any intention of following mechanical principles beyond where they will explain actual manipulation, but as a means of directing attention to percussive acting machines generally, with which forging processes, as before explained, have an intimate connection."After this infernal rumble, deadly silence followed, interrupted only by the groans of the wounded. The German artillery ceased to fire, and from all sides their infantry came rushing on, their faces expressing the terror caused by such great calamities. They were no longer soldiers longing to destroy, but human beings hurrying to go to the assistance of other human beings. TWO:Anybody could have learned that the millionaire was in California, Sandy reflected; it would be easy for a clever jewel robber, one of a band, to impersonate the man when he was caught off guard by their exchange of aircraft.But the same moment his friend, the cashier, came rushing in. His eyes were gleaming behind his spectacles.

ONE:There could be no doubt about that. The label had the same chemist's name on it, with the red caution of "Poison" underneath. The girl put the bottle to her nostrils and noticed the difference in the smell. TWO:Than rightfully to celebrateEvery operation in a pattern-shop has reference to some operation in the foundry, and patterns considered separately from moulding operations would be incomprehensible to any but the skilled. Next to designing and draughting, pattern-making is the most intellectual of what may be termed engineering processesthe department that must include an exercise of the greatest amount of personal judgment on the part of the workman, and at the same time demands a high grade of hand skill.
