      Many clerical gentlemen connected with the University had been ill-treated in the most atrocious manner. The architect Lenertz, a native of Luxemburg, also connected with the University, had been shot, for no reason at all, before the eyes of his wife at the moment that he left the house. And Louvain was so effectively cut off from the outer world that in most convents I was asked whether the rumour was true that the Pope was dead! And at that time his successor had already been appointed.

      It is evident that when the parts of a machine are joined together, each piece which has contact on more than one side must have specific dimensions; it is farther evident that as many of the joints in a machine as are to accommodate the exigencies of construction must be without space, that is, they represent continued sections of what should be solid material, if it were possible to construct the parts in that manner. This also demands specific dimensions.In the driving gearing of planing machines, conditions which favour the reversing movement are high speed and narrow driving belts. The time in which belts may be shifted is as their speed and width; to be shifted a belt must be deflected or bent edgewise, and from this cause wind spirally in order to pass from one pulley to another. To bend or deflect a belt edgewise there will be required a force in proportion to its width, and [133] the time of passing from one pulley to another is as the number of revolutions made by the pulleys.

      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.

      On Thursday everyone, even the persons staying in the Institution and hospitals, were ordered to leave the town, as it was to be shelled. They seemed to have no pity even on the wretched wounded men. Only the male and female nurses remained with these, of their own free will, determined to die with them if necessary.

      4. To cause a movement of the valve after the hammer stops there must be an intermediate agent, that will continue to [163] act after the movement of the hammer drop has ceased.
