THREE: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.

THREE:Plato does, no doubt, make it a charge against the Sophists that their doctrines are not only false and immoral, but that they are put together without any regard for logical coherence. It would seem, however, that this style of attack belongs rather to the later and constructive than to the earlier and receptive period of his intellectual development. The original cause of his antagonism to the professional teachers seems to have been their general pretensions to knowledge, which, from the standpoint of universal scepticism, were, of course, utterly illusive; together with a feeling of aristocratic contempt for a calling in which considerations of187 pecuniary interest were involved, heightened in this instance by a conviction that the buyer received nothing better than a sham article in exchange for his money. Here, again, a parallel suggests itself with the first preaching of the Gospel. The attitude of Christ towards the scribes and Pharisees, as also that of St. Paul towards Simon Magus, will help us to understand how Plato, in another order of spiritual teaching, must have regarded the hypocrisy of wisdom, the intrusion of fraudulent traders into the temple of Delphic inspiration, and the sale of a priceless blessing whose unlimited diffusion should have been its own and only reward.[92]
