DANGEROUS PLACE ON THE SUWO NADA. DANGEROUS PLACE ON THE SUWO NADA. "Richard, it helps the wrong way; I know that story. After hearing that story she is, yes! the one woman of all women to send me this." Another day arose. A courier brought passes for our three or four other wounded to go home as soon as they were fit to travel, and by night they were all gone. At early bedtime came two surgeons of high rank all the way from Johnston's army up in Mississippi. General Austin had asked this favor by telegraph. Harry had been gone thirty-six hours, and Ferry was just asking if he had not yet got back, when the surgeons came in to the room. A pleasantry or two consumed a few moments. Then the surgeon in charge of us told of a symptom or two, to which they responded only "hmm," and began the examination. Miss Harper sent her three nieces away. I lay and listened in the busy stillness. Presently one of the examiners murmured with a certain positiveness to the other, who after a moment's silence replied with conviction; Miss Harper touched our surgeon's arm inquiringly and he looked back in a glad way and nodded. Miss Harper nodded to me; they had located the ball! Now the conversation turned upon men and events of the day, while one of the visitors, with his back to the patient, opened a case of glittering knives. Presently the professional heads came so close together as quite to hide the patient; they spoke once or twice in a manly soothing tone. Miss Harper stroked my temples to keep me down, one of the busy ones spoke again, and lo! the thing was done, there was the ball in the basin. As the men of blood sped through their kind after-work the news flew to and fro; Camille wept,--since she could not hurrah,--Cécile told Charlotte, the heavenly-minded Estelle was confirmed in her faith, Miss Harper's black eyes, after a brief overflow, were keener and kindlier than ever, and as the surgeons spoke the word "done," Ferry asked again if Harry had not got back yet. Pretty soon Harry did arrive, with news of great feats by our cavalry against our old enemy Grierson, in which Austin's brigade had covered themselves with glory, and in which he had had his own share; his hand was swelled as big as his heart. In all the Confederacy no houseful went to sleep that night in sweeter content. I sank into perfect bliss planning a double wedding. "Well, I can name several! I don't call Scott Gholson anybody, but there's Major Harper--No, I'm not talking too loud, Ned isn't hearing a word. Major Harper's so hot against this thing that he brought it up, with me, yesterday on the battlefield." Mrs. Flack held the greater part of herself in a semicircle of red arm. "You are a one," she declared. Then she looked at Mr. Flack, who sat unmoved. "Why don't you laugh. It would do you good. You take everything so serious." "Certainly, captain." The final defeat of polytheism proved, in some respects, an advantage to Neo-Platonism, by compelling it to exchange theological controversy for studies which could be prosecuted, at least for a time, without giving umbrage to the dominant religion. At Alexandria the new spiritualism was associated, on genuinely Platonic principles, with the teaching of geometry by the noble and ill-fated Hypatia. In all the Neo-Platonic schools, whether at Rome, at Alexandria, at Constantinople, or at Athens, the writings of Plato and Aristotle were attentively studied, and made the subject of numerous commentaries, many of which are still extant. This return to the two great masters of idealism was, as we have already said, the most valuable result of the metaphysical revival, and probably contributed more than any other cause to the preservation of their works amidst the general wreck of ancient philosophical literature. Finally, efforts were made to present the doctrine of Plotinus under a more popular or a more scientific form, and to develope it into systematic completeness. [Pg 50] Beyond the "deadening" came a horde of pursuing rebels, firing and yelling like demons. The sight and sound swelled the boys' hearts with the rage of battle. "Why, what in the world have I got on that's military?" asked Billings, looking himself over. "Stephen, you were not used to answer me thus. I charge you, by the authority and love of thy mother, and in the name of the blessed saints, to tell me what has happened." HoME 飞鹰伦理影院ENTER NUMBET 004kdzp.net.cn
