The third plan of boring with bars resting in bearings is more extensively practised, and has the largest range of adaptation. A feature of this plan of boring is that the form of the boring-bar, or any imperfection in its bearings, is communicated to the work; a want of straightness in the bar makes tapering holes. This, of course, applies to cases where a bar is fed through fixed bearings placed at one or both ends of a hole to be bored. If a boring-bar is bent, or out of truth between its bearings, the diameter of the hole being governed by the extreme sweep of the cutters is untrue to the same extent, because as the cutters move along and come nearer to the bearings, the bar runs with more truth, forming a tapering hole diminishing toward the rests or bearings. The same rule applies to some extent in chuck-boring, the form of the lathe spindle being communicated to holes bored; but lathe spindles are presumed to be quite perfect compared with boring bars.
The history of this Crates was distinguished by the one solitary romance of Greek philosophy. A young lady of noble family, named Hipparchia, fell desperately in love with him, refused several most eligible suitors, and threatened to kill herself unless she was given to him in marriage. Her parents in despair sent for Crates. Marriage, for a philosopher, was against the principles of his sect, and he at first joined them in endeavouring to dissuade her. Finding his remonstrances unavailing, he at last flung at her feet the staff and wallet which constituted his whole worldly possessions, exclaiming,8 Here is the bridegroom, and that is the dower. Think of this matter well, for you cannot be my partner unless you follow the same calling with me. Hipparchia consented, and thenceforth, heedless of taunts, conformed her life in every respect to the Cynic pattern.13In multiplying the variations of a measuring implement by mechanism, it is obvious that movable joints must be employed; it is also obvious that no positive joint, whether cylindrical or flat, could be so accurately fitted as to transmit such slight movement as occurs in gauging or measuring. This difficulty is in most measuring instruments overcome by employing a principle not before alluded to, but common in many machines, that of elastic [151] compensation."Most courteous of Shylocks, it is all spent. I am going to be frank with you, which is very virtuous on my part, seeing that you have found me out. That San Salvator property is worth exactly nothing. Also it is mortgaged in four places. But for a bit of pure bad luck I should have got more out of you for it."Before leaving we went back to the hotel for breakfast. Thereit was a first-class hotelthey gave us an apology for coffee, without milk or sugar, and two flimsy pieces of bread, as hard as wood and as black as shoe-polish. I was intensely hungry, and as nowhere at Charleroi anything else could be had, I did my best with the wooden bread and succeeded in washing it down with much chewing and jawing. But the sweet, hard stuff did not suit my digestion, and I felt ill already when at six o'clock we got into the motor-car and left for Dinant.Vis had not been burnt yet, as had been reported in The Netherlands. Only here and there had the shells done some damage, and hundreds of window-panes had been burst by the vibration of the air. As a token of submission to the invader, small white flags hung from all the windows, and these, along the whole length of a street, made a decidedly lamentable impression.That happened each time that he started again, and I was more tired by trying to convince this man than if I had walked all the rest of the way to Brussels. But after all I got there.
FORE:"Lend me 500, Lady Longmere," the Countess asked gaily.
