"5. Van Zuylen, senator.Designing, or generating the plans of machinery, may be considered the leading element in engineering manufactures or machine construction, that one to which all others are subordinate, [75] both in order and importance, and is that branch to which engineering knowledge is especially directed. Designing should consist, first, in assuming certain results, and, secondly, in conceiving of mechanical agents to produce these results. It comprehends the geometry of movements, the disposition and arrangement of material, the endurance of wearing surfaces, adjustments, symmetry; in short, all the conditions of machine operation and machine construction. This subject will be again treated of at more length in another section.

"For the present I have my hands full. I've had some hard problems to solve in the way of plots, but never one like this. Here's Bruce coming along the street. Run away and leave me to my puzzle."

THREE:CHAPTER XVIII. MACHINE COMBINATION.Machine motion is mainly rotary; and as rotary motion is accomplished by cylindrical parts such as shafts, bearings, pulleys and wheels, we find that the greater share of machine tools are directed to preparing cylindrical forms. If we note the area of the turned, bored and drilled surface in ordinary machinery, and compare with the amount of planed surface, we will find the former not less than as two to one in the finer class of machinery, and as three to one in the coarser class; from this may be estimated approximately the proportion of tools required for operating on cylindrical surfaces and plane surfaces; assuming the cutting tools to have the same capacity in the two cases, the proportion will be as three to one. This difference between the number of machines required for cylindrical and plane surfaces is farther increased, when we consider that tools act continually on cylindrical surfaces and intermittently on plane surfaces.

  • THREE:The race was out of their hands.He thought that it was sufficiently protected by the immense Red Cross flag, and the words written on the door by the Germans themselves: "Professor Noyons, Netherland physician, to be spared." But he had been mistaken. The soldiers did not respect anything, and had forced an entry into the house, wounded that servant, and then wrecked everything in the most scandalous manner. Beautiful large Japanese jars had been smashed to pieces, valuable furniture damaged by knocking and breaking large pieces out of it with rifles and bayonets. A fine carpet was burned, as well as many pieces of furniture. A hole was burned even in the floor.

70If the nature of their errand was not precisely calculated to win respect for the profession of the Athenian envoys, the subsequent proceedings of one among their number proved still less likely to raise it in the estimation of those whose favour they sought to win. Hellenic culture was, at that time, rapidly gaining ground among the Roman aristocracy; Carneades, who already enjoyed an immense reputation for eloquence and ingenuity among his own countrymen, used the opportunity offered by his temporary residence in the imperial city to deliver public lectures on morality; and such was the eagerness to listen that for a time the young nobles could think and talk of nothing else. The subject chosen was justice. The first lecture recapitulated whatever had been said in praise of that virtue by Plato and Aristotle. But it was a principle of the sect to which Carneades belonged that every affirmative proposition, however strongly supported, might be denied with equal plausibility. Accordingly, his second discourse was entirely devoted to upsetting the conclusions advocated in the first. Transporting the whole question, as would seem, from a private to a public point of view, he attempted to show, from the different standards prevailing in different countries, that there was no such thing as an immutable rule of right; and also that the greatest and most successful States had profited most by unscrupulous aggressions on their weaker neighbourshis most telling illustrations being drawn from the history of the Romans themselves. Then, descending once more to private life, the sceptical lecturer expatiated on the frequency of those cases in which justice is opposed to self-interest, and the folly of122 sacrificing ones own advantage to that of another. Suppose a good man has a runaway slave or an unhealthy house to sell, will he inform the buyer of their deficiencies, or will he conceal them? In the one case he will be a fool, in the other case he will be unjust. Again, justice forbids us to take away the life or property of another. But in a shipwreck, will not the just man try to save his life at anothers expense by seizing the plank of which some weaker person than himself has got holdespecially if they are alone on the sea together? If he is wise he will do so, for to act otherwise would be to sacrifice his life. So also, in flying before the enemy, will he not dispossess a wounded comrade of his horse, in order to mount and escape on it himself? Here, again, justice is incompatible with self-preservationthat is to say, with wisdom123!213"PROCLAMATIONTomorrow a whole hoard of tradesmen would be down upon Lytton Avenue, but for the present Hetty was left in peace. Mamie was very far from well, flushed and feverish, so that at eleven o'clock she decided to call in Bruce. She rang the bell, but no servant appeared. She rang again, and went down presently into the basement to investigate.
