THREE:Were it not that moral influences in learning mechanics, as in all other kinds of education, lie at the bottom of the whole matter, the subject of this chapter would not have been introduced. But it is the purpose, so far as possible, to notice everything that concerns an apprentice and learner, and especially what he has to deal with at the outset; hence some remarks upon the nature of apprentice engagements will not be out of place. To acquire information or knowledge of any kind successfully and permanently, it must be a work of free volition, as well as from a sense of duty or expediency; and whatever tends to create love and respect for a pursuit or calling, becomes one of the strongest incentives for its acquirement, and the interest taken by an [19] apprentice in his business is for this reason greatly influenced by the opinions that he may hold concerning the nature of his engagement.The means of supporting cores must be devised, or at least understood, by pattern-makers; these supports consist of 'prints' and 'anchors.' Prints are extensions of the cores, which project through the casting and extend into the sides of the mould, to be held by the sand or by the flask. The prints of cores have duplicates on the patterns, called core prints, which are, or should be, of a different colour from the patterns, so as to distinguish one from the other. The amount of surface required to support cores is dependent upon their weight, or rather upon their cubic contents, because the weight of a core is but a trifling matter [96] compared to its floating force when surrounded by melted metal. An apprentice in studying devices for supporting cores must remember that the main force required is to hold them down, and not to bear their weight. The floating force of a core is as the difference between its weight and that of a solid of metal of the same size��a matter moulders often forget to consider. It is often impossible, from the nature of castings, to have prints large enough to support the cores, and it is then effected by anchors, pieces of iron that stand like braces between the cores and the flasks or pieces of iron imbedded in the sand to receive the strain of the anchors. FORE:Cynicism, if we understand it rightly, was only the mutilated form of an older philosophy having for its object to set morality free from convention, and to found it anew on a scientific knowledge of natural law. The need of such a system was not felt so long as Plato and Aristotle were unfolding their wonderful schemes for a reorganisation of action and belief. With the temporary collapse of those schemes it came once more to the front. The result was a new school which so thoroughly satisfied the demands of the age, that for five centuries the noblest spirits of Greece and Rome, with few exceptions, adhered to its doctrines; that in dying it bequeathed some of their most vital elements to the metaphysics and the theology by which it was succeeded; that with their decay it reappeared as an important factor in modern thought; and that its name has become imperishably associated in our own language with the proud endurance of suffering, the self-sufficingness of conscious rectitude, and the renunciation of all sympathy, except what may be derived from contemplation of the immortal dead, whose heroism is7 recorded in history, or of the eternal cosmic forces performing their glorious offices with unimpassioned energy and imperturbable repose."Oh, go on!" I answered. "I don't think that I need fear anything of the kind. I am in any case a Netherlander!"
