THREE:No little astonishment was therefore created by an interview which I published with Dr. van der Goot of The Hague, who did so much excellent work in the Red Cross Hospital at Maastricht. He also had come to believe all these stories, and as everybody always mentioned a large hospital in Aix-la-Chapelle, which was said to be full of similarly mutilated soldiers, Dr. van der Goot went to that91 town to see for himself. The chief medical officer of that hospital in a conversation stated that not one single case of that sort had been treated in his institution nor in any of the other local hospitals where he was a visiting physician. At a meeting of the medical circle just lately held he had not heard one word, nor had any one colleague, about the treatment of similar cases.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.
