ONE:In planing and turning, the tools require no exact form; they can be roughly made, except the edge, and even this, in most cases, is shaped by the eye. Such tools are maintained at a trifling expense, and the destruction of an edge is a matter of no consequence. The form, temper, and strength can be continually adapted to the varying conditions of the work and the hardness of material. The line of division between planing and milling is fixed by two circumstances��the hardness and uniformity of the material to be cut, and the importance of duplication. Brass, clean iron, soft steel, or any homogeneous metal not hard enough to cause risk to the tools, can be milled at less expense than planed, provided there is enough work of a uniform character to justify the expense of milling tools. Cutting the teeth of wheels is an example where milling is profitable, but not to the extent generally supposed. In the manufacture of small arms, sewing machines, clocks, and especially watches, where there is a constant and exact duplication of parts, milling is indispensable. Such manufactures are in some cases founded on milling operations, as will be pointed out in another chapter. TWO:"I'll try," she said, "but then I handle so much money. I play cards, I bet on horses. There are scores of ways. But I'll try."

ONE:A great reformer of the last generation, finding that the idea of Nature was constantly put forward to thwart his most cherished schemes, prepared a mine for its destruction which was only exploded after his death. Seldom has so powerful a charge of logical dynamite been collected within so small a space as in Mill��s famous Essay on Nature. But the immediate effect was less than might have been anticipated, because the attack was supposed to be directed against religion, whereas it was only aimed at an abstract metaphysical dogma, not necessarily connected with any theological beliefs, and held by many who have discarded all such beliefs. A stronger impression was, perhaps, produced by the nearly simultaneous declaration of Sir W. Gull��in reference to the supposed vis medicatrix naturae��that, in cases of disease, ��what Nature wants is to put the man in his coffin.�� The new school of political economists have also done much to show that legislative interference with the ��natural laws�� of wealth need by no means be so generally mischievous as was once supposed. And the doctrine of Evolution, besides breaking down the old distinctions between Nature and Man, has represented the former as essentially variable, and therefore, to that extent, incapable of affording a fixed standard for moral action. It is, however, from this school that a new49 attempt to rehabilitate the old physical ethics has lately proceeded. The object of Mr. Herbert Spencer��s Data of Ethics is, among other points, to prove that a true morality represents the ultimate stage of evolution, and reproduces in social life that permanent equilibration towards which every form of evolution constantly tends. And Mr. Spencer also shows how evolution is bringing about a state of things in which the self-regarding shall be finally harmonised with the social impulses. Now, it will be readily admitted that morality is a product of evolution in this sense that it is a gradual formation, that it is the product of many converging conditions, and that it progresses according to a certain method. But that the same method is observed through all orders of evolution seems less evident. For instance, in the formation, first of the solar system, and then of the earth��s crust, there is a continual loss of force, while in the development of organic life there is as continual a gain; and on arriving at subjective phenomena, we are met by facts which, in the present state of our knowledge, cannot advantageously be expressed in terms of force and matter at all. Even if we do not agree with George Sand in thinking that self-sacrifice is the only virtue, we must admit that the possibility, at least, of its being sometimes demanded is inseparable from the idea of duty. But self-sacrifice cannot be conceived without consciousness; which is equivalent to saying that it involves other than mechanical notions. Thus we are confronted by the standing difficulty of all evolutionary theories, and on a point where that difficulty is peculiarly sensible. Nor is this an objection to be got rid of by the argument that it applies to all philosophical systems alike. To an idealist, the dependence of morality on consciousness is a practical confirmation of his professed principles. Holding that the universal forms of experience are the conditions under which an object is apprehended, rather than modifications imposed by an unknowable object on an unknowable subject, and that these50 forms are common to all intelligent beings, he holds also that the perception of duty is the widening of our individual selves into that universal self which is the subjective side of all experience. TWO:"So recently! Ah, this is a veritable house of tragedies. I must get you to explain. I have come here direct from Paris to get certain papers. Put the gas out and come into the dining-room where the shutters are up. We don't want the police fussing about. You can tell me everything. If I don't make a mistake you are Mr. Gilbert Lawrence, the novelist."

ONE:"A beauty!" the Countess exclaimed, "And the same action as my own. I believe I know as much about it as my chauffeur. Captain Gifford, let me try it alone, do. Harris, give me a coat. No, one of the gentlemen's overcoats--that grey one will do. Do let me go round the square alone!" TWO:A milling tool with twenty edges should represent as much wearing capacity as a like number of separate tools, and may be said to equal twenty duplicate tools; hence, in cutting grooves, notches, or similar work, a milling tool is equivalent to a large number of duplicate single tools, which cannot be made or set with the same truth; so that milling secures accuracy and duplication, objects which are in many cases more important than speed.

ONE:Although I had been commanded to return "at once" to Maastricht, I succeeded in having a chat here and there with the inhabitants of Riemst. I had visited the village about eight days ago, but what a change! Then the people assured me that "die Duutschen"[2] were not so bad after all, that they were compelled to do their duty, and were kind to the inhabitants if these were kind to them. TWO:Cores expand when heated, and require an allowance in their dimensions the reverse from patterns; this is especially the case when the cores are made upon iron frames. For cylindrical cores less than six inches diameter, or less than two feet long, expansion need not be taken into account by pattern-makers, but for large cores careful calculation is required. The expansion of cores is as the amount of heat imparted to them, and the amount of heat taken up is dependent upon the quantity of metal that may surround the core and its conducting power.
