      Drilling, more than any other operation in metal cutting, requires the sense of feeling, and is farther from such conditions as admit of power feeding. The speed at which a drill may cut without heating or breaking is dependent upon the manner in which it is ground and the nature of the material drilled, the working conditions may change at any moment as the drilling progresses; so that hand feed is most suitable. Drilling machines arranged with power feed for boring should have some means of permanently disengaging the feeding mechanism to prevent its use in ordinary drilling."What," I exclaimed, "you dare to say that the Netherlanders act with the Germans? No, shall I tell you something? The Germans have asked206 the Netherland Government for permission to place a 42 cm. gun on their territory to shell Antwerp from that side, but the Netherland Government have refused."


      93But stop and think of these things, he continued, urging his two friends to use their own imaginations. The amphibian was old-looking and didnt seem to be much good, and the gas gauge was broken, and the chewing gum was quite fresh. That might look as though


      CHAPTER XL. INVENTION.

      The prevailing custom of casting machine frames in one piece, or in as few pieces as possible, leads to a great deal of bar-boring, most of which can be performed accurately enough by boring bars supported in and fed through bearings. By setting up temporary bearings to support boring-bars, and improvising means of driving and feeding, most of the boring on machine frames can be performed on floors or sole plates and independent of boring machines and lathes. There are but few cases in which the importance of studying the principles of tool action is more clearly demonstrated than in this matter of boring; even long practical experience seldom leads to a thorough understanding of the [139] various problems which it involves.

      No! he cried. No! LarryDickyou, Mister! Come on, quickunder these trees yonder!VI.


      The remarks, given in a former place, relating to tools for turning, apply to those for planing as well, except that in planing tools greater rigidity and strength are required.

      The final antithesis of conscious life is that between the398 individual and the state. In this sense, Aristotles Politics is the completion of his Ethics. It is only in a well-ordered community that moral habits can be acquired; and it is only in such a community that the best or intellectual life can be attained, although, properly speaking, it is not a social life. Nevertheless, the Politics, like every other portion of Aristotles system, reproduces within itself the elements of an independent whole. To understand its internal organisation, we must begin by disregarding Aristotles abortive classification (chiefly adapted from Plato) of constitutions into three legitimateMonarchy, Aristocracy, and Republic; and three illegitimateDemocracy, Oligarchy, and Tyranny. Aristotle distinguishes them by saying that the legitimate forms are governed with a view to the general good; the illegitimate with a view to the interests of particular classes or persons. But, in point of fact, as Zeller shows,291 he cannot keep up this distinction; and we shall better understand his true idea by substituting for it anotherthat between the intellectual and the material state. The object of the one is to secure the highest culture for a ruling caste, who are to abstain from industrial occupations, and to be supported by the labour of a dependent population. Such a government may be either monarchical or aristocratic; but it must necessarily be in the hands of a few. The object of the other is to maintain a stable equilibrium between the opposing interests of rich and poortwo classes practically distinguished as the few and the many. This end is best attained where supreme power belongs to the middle class. The deviations are represented by oligarchy and tyranny on the one side, and by extreme democracy on the other. Where such constitutions exist, the best mode of preserving them is to moderate their characteristic excess by borrowing certain institutions from the opposite form of government, or by modifying their own institutions in a conciliatory sense."No, sir, I am returning from there."

      That same Friday evening the women and children living in the Rue de la Station were told to leave their houses as the whole street was to be burned down. Everybody fled, but the design was not executed. The burgomaster and his son were taken prisoners, and brought to Tongres; later on the son was released; the Very Reverend the Dean was also arrested.CHAPTER XXXIII A BATTLE ABOVE THE CLOUDS
