FORE:CHAPTER XXV. A CHECK.
FORE: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 sizea 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.An apprentice may get a clear idea of this venting process by inspecting tubular core barrels, such as are employed in moulding pipes or hollow columns, or by examining ordinary cores about a foundry. Provision of some kind to 'carry off the vent,' as it is termed by moulders, will be found in every case. The venting of moulds is even more important than venting cores, because core vents only carry off gas generated within the core itself, while the gas from its exterior surface, and from the whole mould, has to find means of escaping rapidly from the flasks when the hot metal enters.
FORE:"It was in the interests of our suffering country, and we are those who ought to be grateful. May I insist once more that you ask our refugees to come back to Antwerp and don't omit to state the three favourable regulations...."The work of these sisters is the education of neglected children, and they spoke about their fears during the last momentous days. During the bombardment they stayed night and day with all those little ones in the heavily vaulted cellars of the nunnery, praying all the time before the Blessed Sacrament that had been removed from the chapel and taken into the cellar for safety.
FORE:The treatment of the passions by the Stoic school presents greater difficulties, due partly to their own vacillation, partly to the very indefinite nature of the feelings in question. It will be admitted that here also the claims of duty are supreme. To follow the promptings of fear or of anger, of pity or of love, without considering the ulterior consequences of our action, is, of course, wrong. For even if, in any particular instance, no harm comes of the concession, we cannot be sure that such will always be the case; and meanwhile the passion is23 strengthened by indulgence. And we have also to consider the bad effect produced on the character of those who, finding themselves the object of passion, learn to address themselves to it instead of to reason. Difficulties arise when we begin to consider how far education should aim at the systematic discouragement of strong emotion. Here the Stoics seem to have taken up a position not very consistent either with their appeals to Nature or with their teleological assumptions. Nothing strikes one as more unnatural than the complete absence of human feeling; and a believer in design might plausibly maintain that every emotion conduced to the preservation either of the individual or of the race. We find, however, that the Stoics, here as elsewhere reversing the Aristotelian method, would not admit the existence of a psychological distinction between reason and passion. According to their analysis, the emotions are so many different forms of judgment. Joy and sorrow are false opinions respecting good and evil in the present: desire and fear, false opinions respecting good and evil in the future.53 But, granting a righteous will to be the only good, and its absence the only evil, there can be no room for any of these feelings in the mind of a truly virtuous man, since his opinions on the subject of good are correct, and its possession depends entirely on himself. Everything else arises from an external necessity, to strive with which would be useless because it is inevitable, foolish because it is beneficent, and impious because it is supremely wise.
