"Never mind that yet. I didn't get this information from you. Behold the picture! You are sitting in your room on the night previous to the murder--a few hours before it in fact. Enter to you a more or less picturesque individual who tells you a story of a picture. It is an heirloom in his family. The family have had to part with it in their dark days. Now the same picturesque individual has become rich. Imagine his delight when he sees this family treasure in a shop window."
ONE:Ive just thought of a good scheme. Has Jeffertaken you into his confidence any?"But I'll swear to you," the Countess broke in vehemently. "I'll swear----"
ONE:Now what? demanded Jeff. We cant go in any closer.We have now reached a point in history where the Greek intellect seems to be struck with a partial paralysis, continuing for a century and a half. During that period, its activitywhat there is of itis shown only in criticism and erudition. There is learning, there is research, there is acuteness, there is even good taste, but originality and eloquence are extinct. Is it a coincidence, or is it something more, that this interval of sterility should occur simultaneously with the most splendid period of Latin literature, and that the new birth of Greek culture should be followed by the decrepitude and death of the Latin muse? It is certain that in modern Europe, possessing as it does so many independent sources of vitality, the flowering-times of different countries rarely coincide; England and Spain, from the middle of the sixteenth to the middle of the seventeenth century, being the only instances that we can recall of two countries almost simultaneously reaching the highest point of their literary development. Possibly, during the great age of Latin literature, all the most aspiring Greeks found employment as tutors in Roman families; while the reading public of the West were too much absorbed by the masterpieces composed in their own language,166 or too elated with the consciousness of a new superiority, to encourage the rivalry of those from whom they had wrested not only poetical independence, but also, what till then had never been disputed with the Greeks, supreme dominion in the world of mind. It is, at any rate, significant that while Greek was the favourite language of Roman lovers in the time of Lucretius and again in the time of Juvenal, there are no allusions to its having been employed by them during the intermediate period.264 Be this as it may, from the fall of the Republic to the time of Trajan, philosophy, like poetry and eloquenceor at least all philosophy that was positive and practicalbecame domiciled in Rome, and received the stamp of the Roman character. How Stoicism was affected by the change has been pointed out in a former chapter. What we have now to study is chiefly the reaction of Rome on the Greek mind, and its bearing on the subsequent development of thought.
TWO:58By examining the history of great achievements in the mechanic arts, it will be seen that success has been mainly dependent upon predicting future wants, as well as upon an ability to supply such wants, and that the commercial value of mechanical improvements is often measured by conditions that the improvements themselves anticipate. The invention of machine-made drills, for example, was but a small matter; but the demand that has grown up since, and because of their existence, has rendered this improvement one of great value. Moulded bearings for shafts were also a trifling improvement when first made, but it has since influenced machine construction in America in a way that has given great importance to the invention.
TWO:Forging plant consists of rolling mills, trip-hammers, steam-hammers, drops, and punches, with furnaces, hearths, and blowing apparatus for heating. A general characteristic of all forging machines is that of a great force acting throughout a short distance. Very few machines, except the largest hammers, exceed a half-inch of working range, and in average operations not one-tenth of an inch.
TWO:Invention, as applied to mechanical improvements, should not mean chance discovery. Such a meaning is often, if not generally, attached to the term invention, yet it must be seen that results attained by a systematic course of reasoning or experimenting can have nothing to do with chance or even discovery. Such results partake more of the nature of demonstrations, a name peculiarly suitable for such inventions as are the result of methodical purpose.
TWO:A carriage moving on angular ways always moves steadily and easily, without play in any direction until lifted from its bearing, which rarely happens, and its lifting is easily opposed by adjustable gibs. A carriage on a flat shear is apt to have play in a horizontal direction because of the freedom which must exist to secure easy movement. In the case of tracks, it may also be mentioned that the weight of a carriage acts as a constant force to hold it steady, while with a flat shear the weight of a carriage is in a sense opposed to the ways, and has no useful effect in steadying or guiding. The rigidity and steadiness of tool movement is notoriously in favour of triangular tracks, so much so that nearly all American machine tool-makers construct lathes in this manner, although it adds no inconsiderable cost in fitting.
THREE:"Some days ago you bought a picture," Herr Kronin proceeded. "It was a small picture of the early Dutch School, signed J. Halbin. A woman nursing a sick child, and the father looking on. Not a valuable picture."
