During the night they passed Cape King and entered Yeddo bay. The great light-house that watches the entrance shot its rays far out over the waters and beamed a kindly welcome to the strangers. Slowly they steamed onward, keeping a careful lookout for the numerous boats and junks that abound there, and watching the hundreds of lights that gleamed along the shore and dotted the sloping hill-sides. Sixty miles from[Pg 77] Cape King, they were in front of Yokohama; the engines stopped, the anchor fell, the chain rattled through the hawse-hole, and the ship was at rest, after her long journey from San Francisco. Our young adventurers were in Japan. CHAPTER VII. A HIGH-PRIEST IN FULL COSTUME. A HIGH-PRIEST IN FULL COSTUME. "Tst!" he laid a finger on my lips; "'twill not be hard; we are not going on a scout--to jump fences." He began to make actual preparations, and presently helped me draw my shirt into place again over the clean bandages, while the old man went out after fresh water. "I am a hundred times more fit to go than to stay," he suddenly resumed. "I must go. Ah, idleness, there is nothing like idleness to drive a man mad; I must have something to do--to-night--at once." I wish I knew how to give the words with his quiet intensity. Leona said nothing. There was a queer, strained look, half of admiration, on her face. But she uttered no protest, no denial. Next in order are strains. As the cutting action is the source of strains, and as the resistance offered by the cutting tools is as the length or width of the edges, it will be found in the present case that while other conditions thus far have pointed to small proportions, there is now a new one which calls for large proportions. In displacing the metal between teeth of three-quarters of an inch pitch, the cutting edge or the amount of surface acted upon is equal to a width of one inch and a half. It is true, the displacement may be small at each cut, but the strain is rather to be based upon the breadth of the acting edge than the actual displacement of metal, and we find here strains equal to the average duty of a large planing machine. This strain radiates from the cutting point as from a centre, falling on the supports of the work with a tendency to force it from the framing. Between the rack and the crank-shaft bearing, through the medium of the tool, cutter bar, connection, and crank pin, and in various directions and degrees, this strain may be followed by means of a simple diagram. Besides this cutting strain, there are none of importance; the tension of the belt, the side thrust in bearings, the strain from the angular thrust of the crank, and the end thrust of the tool, although not to be lost sight of, need not have much to do with problems of strength, proportion, and arrangement. "No, only a couple of minutes." A Hellene, and an aristocrat as well. Or, using the word in its most comprehensive sense, we may say that he was an aristocrat all round, a believer in inherent superiorities of race, sex, birth, breeding, and age. Everywhere we find him restlessly searching after the wisest, purest, best, until at last, passing beyond the limits of existence itself, words fail him to describe the absolute ineffable only good, not being and not knowledge, but creating and inspiring both. Thus it came to pass that his hopes of effecting a thorough reform did not lie in an appeal to the masses, but in the selection and198 seclusion from evil influences of a few intelligent youths. Here we may detect a remarkable divergence between him and his master. Socrates, himself a man of the people, did not like to hear the Athenians abused. If they went wrong, it was, he said, the fault of their leaders.126 But according to Plato, it was from the people themselves that corruption originally proceeded, it was they who instilled false lessons into the most intelligent minds, teaching them from their very infancy to prefer show to substance, success to merit, and pleasure to virtue; making the study of popular caprice the sure road to power, and poisoning the very sources of morality by circulating blasphemous stories about the gods—stories which represented them as weak, sensual, capricious beings, setting an example of iniquity themselves, and quite willing to pardon it in men on condition of going shares in the spoil. The poets had a great deal to do with the manufacture of these discreditable myths; and towards poets as a class Plato entertained feelings of mingled admiration and contempt. As an artist, he was powerfully attracted by the beauty of their works; as a theologian, he believed them to be the channels of divine inspiration, and sometimes also the guardians of a sacred tradition; but as a critic, he was shocked at their incapacity to explain the meaning of their own works, especially when it was coupled with ridiculous pretensions to omniscience; and he regarded the imitative character of their productions as illustrating, in a particularly flagrant manner, that substitution of appearance for reality which, according to his philosophy, was the deepest source of error and evil. 178 It startled Sandy to see Jeff turn in at the old house, climb the veranda steps, cross the porch to the door—and go in. "Foster?" one drawled, "he'll be along presently, I reckon." Chapter 21 "I'm not trying to persuade you of anything." The woman wouldn't listen, that was the whole trouble: in the harsh bright light of morning she sat like a stone statue, casting a shadow of black on the polished desk. This was Dr. Haenlingen—and how did you talk to Dr. Haenlingen? But it was important, Norma reminded herself again: it was perfectly possible that the entire group of people at the party would be downgraded, or at the least get marked down on their records. "But we weren't doing anything harmful. If you have a party you've got to expect people to—oh, to get over-enthusiastic, maybe. But certainly there was nothing worth getting angry about. There was—" Dancing!... dancing!... Dying!... dying! Even the tune had faded now, and she could see nothing—only a grey patch where the window had been. She was not frightened, only very lonely. Her legs were like ice, and the inside of her mouth felt all rough and numb. HoME 国外无码成人动漫网站ENTER NUMBET 008mrmyxjvh.com.cn
